CAT 6 Double CV Design for Maximum Articulation<br \/>\nThe CAT 6 constant-velocity configuration positions an 80-degree wide-angle CV joint on the tractor PTO output end and a 50-degree CV joint on the discbine input end. This dual-CV architecture eliminates the cyclic torque spikes and torsional vibration that destroy standard U-joint shafts during tight headland turns, slope mowing, and offset cutting passes. The result is noticeably smoother power delivery at both 540 and 1000 RPM PTO speeds, reduced wear on the tractor gearbox, and a longer effective service life for all connected drivetrain components. Ideal for offset and bent-tongue discbine configurations where articulation angles frequently exceed 30 degrees.<\/p>\n<p>2. Precision-Machined Alloy Steel Tubes and Yokes<br \/>\nThe PTO shaft tubing on this unit is drawn from high-grade alloy steel and precision-machined to OEM-equivalent dimensional tolerances using advanced CNC turning centers. Each PTO shaft yoke and cross-and-bearing assembly undergoes induction hardening and shot-blasting to maximize surface fatigue resistance. The telescoping inner and outer profiles are profiled to match OEM PTO shaft dimensions exactly, ensuring slip-fit assembly without shimming or adapter collars. Heavy-duty snap rings and retention clips prevent axial disengagement even under shock-load events. This commitment to dimensional precision means the shaft slides straight onto your tractor PTO stub and discbine input without any modification.<\/p>\n<p>3. Full-Length Polyethylene PTO Shaft Guard Included<br \/>\nEvery unit ships with a complete PTO shaft cover and PTO shaft guard assembly manufactured from high-density polyethylene. The guard fully encloses the rotating shaft and both CV joints from end to end, satisfying CE and OSHA PTO safety requirements without additional purchases. Safety cones at both ends deflect loose material and protect bystanders from contact with the spinning components. The guard profile is designed with adequate radial clearance to avoid contact with the shaft at any rated articulation angle, preventing the heat buildup and premature wear that occur when poorly designed guards rub against shaft bodies during turning.<\/p>\n<p>4. Shear Bolt Overload Protection System<br \/>\nKonfigurasi aci PTO bolt ricih ini menggabungkan antara muka bolt ricih aci PTO yang dinilai ketepatan pada sambungan yoke, yang direka bentuk untuk patah pada ambang tork yang telah ditentukan sebelum kerosakan dahsyat boleh merebak ke kotak gear PTO traktor atau aci input dan set gear serong cakera. Tempat duduk bolt ricih diseragamkan supaya bahagian aci PTO gantian mudah didapati di seluruh dunia. Tidak seperti sistem klac geseran yang boleh tergelincir tanpa diduga semasa musim memotong rumput, kaedah bolt ricih menyediakan peristiwa beban lampau yang jelas dan boleh dipercayai secara mekanikal yang boleh dikenal pasti, dibetulkan dan ditetapkan semula oleh pengendali di lapangan dalam beberapa minit menggunakan sepana asas.<\/p>\n<p>5. ISO9001 and CE Certified Quality Assurance<br \/>\nCMN Transmission holds ISO9001, CE, and TS16949 certifications, and every tractor PTO shaft produced undergoes a multi-stage quality inspection protocol covering raw material certification, dimensional verification, dynamic balance testing, torque rating validation, and surface finish inspection before shipment. These standards are not merely administrative credentials; they reflect a production culture of documented process control and measurable output quality. For international buyers and fleet equipment managers, certified compliance reduces procurement risk, simplifies customs documentation, and provides the documentary evidence required for warranty claims and insurance purposes. Certification records and test reports are available upon request for every batch order.<\/p>\n<p>6. Factory-Direct Pricing and Custom PTO Shaft Options<br \/>\nBecause CMN Transmission is an integrated manufacturer and trading company, buyers receive custom PTO shaft manufacturing support at factory-direct prices with no dealer-chain markups. Non-standard PTO shaft sizes and PTO shaft dimensions are accommodated through our in-house engineering team, which provides dimensional drawings, torque calculations, and prototype approval within days. This customization capability makes CMN the preferred supplier for agricultural equipment OEMs requiring production-volume tractor PTO shafts built to proprietary specifications, as well as for repair depots that need a single versatile PTO shaft adapter range to cover multiple machine models across their service fleet.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-7022 size-full\" src=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/04\/PTO-Shaft-for-New-Holland-Disc-Mower-9.webp\" alt=\"PTO Shaft for New Holland Disc Mower\" width=\"1200\" height=\"800\" srcset=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/04\/PTO-Shaft-for-New-Holland-Disc-Mower-9.webp 1200w, https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/04\/PTO-Shaft-for-New-Holland-Disc-Mower-9-980x653.webp 980w, https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/04\/PTO-Shaft-for-New-Holland-Disc-Mower-9-480x320.webp 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) and (max-width: 980px) 980px, (min-width: 981px) 1200px, 100vw\" \/><\/p>\n<h2>Prinsip Kerja Aci PTO Pemotong Cakera<\/h2>\n<p>Aci pemacu PTO pada New Holland Discbine 411 berfungsi sebagai satu-satunya penghubung mekanikal antara stub output pengangkut kuasa traktor dan kotak gear input mesin pemotong cakera. Apabila pengendali traktor mengaktifkan PTO, kuasa berputar pada kelajuan 540 atau 1000 RPM dihantar melalui aci stub traktor ke dalam pemasangan yoke aci pemacu PTO traktor, kemudian secara paksi di sepanjang tiub aci PTO teleskopik, dan keluar melalui yoke alat ke dalam kotak gear serong cakera. Profil aci dalaman dan luaran teleskopik membolehkan panjang aci PTO keseluruhan berubah secara dinamik apabila ketinggian hitch berubah semasa operasi lapangan dan semasa pengangkutan, memastikan penghantaran tork berterusan tanpa pengikatan atau pelepasan tanpa mengira kedudukan menegak alat berbanding traktor.<\/p>\n<p>Conventional single-joint PTO shaft u joint drivelines suffer from a fundamental mechanical limitation: when the input and output shafts are not co-axial (i.e., when the shaft runs at an angle), the angular velocity of the output shaft oscillates twice per revolution. At typical disc mower operating speeds, this cyclic velocity variation generates intense torsional pulsations that stress the drivetrain components, produce audible vibration, and dramatically reduce the service life of connected PTO shaft universal joint assemblies, gearbox input bearings, and even tractor PTO clutch packs.<\/p>\n<p>Reka bentuk CV berganda CAT 6 pada aci PTO cakera ini menghapuskan masalah ini sepenuhnya. Sambungan CV 80 darjah sudut lebar di bahagian traktor menggunakan mekanisme bola-dan-sangkar yang mengekalkan halaju output yang malar sempurna tanpa mengira sudut antara stub PTO traktor dan garis tengah aci, walaupun semasa selekoh tanjung tajam. Ini amat penting untuk New Holland 411, yang menggunakan konfigurasi lidah bengkok atau hitch ofset yang secara rutin meletakkan aci pemacu PTO pada sudut ekstrem semasa manuver di lapangan. Sambungan CV 50 darjah di hujung alat menyediakan peringkat penyamaan halaju kedua pada sambungan cakera, memastikan kotak gear input pemotong cakera menerima tork halaju malar yang lancar walaupun semasa pergerakan apungan sisi kepala pemotong di atas tanah yang tidak rata.<\/p>\n<p>When the disc mower encounters an overload event such as striking a submerged rock, a hardwood stump, or an accumulation of material wrapped around the disc assembly, the instantaneous torque spike in the driveline can reach several times the rated operating torque within milliseconds. Without a protective device, this peak torque would shear the input shaft of the discbine gearbox, fracture the tractor PTO output shaft, or strip the splines from the PTO shaft yoke. The shear pin PTO shaft arrangement on this unit addresses this risk by incorporating pre-calculated shear elements that sacrifice themselves at a defined torque limit, absorbing the energy of the impact and protecting all downstream drivetrain components from damage. Replacement PTO shaft shear bolt kits are inexpensive and can be installed in the field in under five minutes, getting the machine back to work quickly after an overload event.<\/p>\n<p>The PTO shaft u joint cross-and-bearing assemblies are packed with high-performance grease at the factory and fitted with grease nipples (zerks) for periodic re-lubrication in the field. The CV ball-and-cage elements operate in a sealed grease reservoir that provides long-interval maintenance capability. The telescoping PTO shaft tubing profile is coated with a low-friction polymer lining that maintains smooth sliding action under load and prevents the tube seizure that can occur with uncoated profiles when dirt or crop debris infiltrates the telescope joint during field operation.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-7014 size-full\" src=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/04\/PTO-Shaft-for-New-Holland-Disc-Mower-1.webp\" alt=\"PTO Shaft for New Holland Disc Mower\" width=\"1200\" height=\"760\" srcset=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/04\/PTO-Shaft-for-New-Holland-Disc-Mower-1.webp 1200w, https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/04\/PTO-Shaft-for-New-Holland-Disc-Mower-1-980x621.webp 980w, https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/04\/PTO-Shaft-for-New-Holland-Disc-Mower-1-480x304.webp 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) and (max-width: 980px) 980px, (min-width: 981px) 1200px, 100vw\" \/><\/p>\n<h2>Kawasan Aplikasi<\/h2>\n<p><strong>1. Penuaian Jerami<\/strong><br \/>\nThe primary use case for this disc mower PTO shaft. The disc mower cuts grasses and legumes into windrows, while the integrated conditioning rolls crimp and crack the stems to accelerate field drying before baling. A reliable, vibration-free PTO driveline shaft for disc mower operation is essential for maintaining consistent cutter disc speed across the full cutting pass, ensuring clean, even cuts that maximize forage quality and minimise leaf shatter in high-value crops such as alfalfa and clover.<\/p>\n<p><strong>2. Penuaian Makanan Rumput<\/strong><br \/>\nMowing high-value crops like alfalfa, clover, and ryegrass at the correct stage of maturity requires precise, consistent cutter disc speed to maximize nutritional content for livestock feed, whether the crop is stored as dry hay or green chop. The constant-velocity design of this <a href=\"https:\/\/korea-transmission.com\/ms\/pto-shafts\/\"><strong>aci PTO pertanian<\/strong><\/a> maintains even disc speed across the full PTO speed range, reducing leaf loss and mechanical damage to the plant material, which directly preserves the protein and digestibility values that determine the commercial value of the harvested forage crop.<\/p>\n<p><strong>3. Pengeluaran Silaj<\/strong><br \/>\nCutting crops at higher moisture levels for fermented silage storage in bunkers, pits, or wrapped bales requires fast, even cutting to ensure uniform fermentation throughout the clamp. A heavy-duty tractor PTO shaft that transmits power smoothly and without interruption is essential for maintaining the high field speeds needed during the narrow harvesting window that exists between the correct crop moisture content and field deterioration. The shear bolt protection on this unit also prevents costly gearbox damage when processing dense, high-moisture crop stands.<\/p>\n<p><strong>4. Pengurusan Padang Rumput<\/strong><br \/>\nTopping and trimming pastures to control rank or stemmy growth, remove seed heads, and encourage fresh, palatable re-growth for grazing animals represents a regular seasonal workload for mixed livestock farms. In pasture topping applications, the mower frequently encounters uneven terrain, buried stones, and surface debris that would destroy a standard PTO drive shaft. The shear bolt overload protection on this PTO shaft for New Holland discbine hardware absorbs impact events safely and returns the machine to work within minutes, protecting both the mower gearbox and the tractor PTO output.<\/p>\n<p><strong>5. Penamatan Tanaman Penutup Bumi<\/strong><br \/>\nCutting down winter cover crops such as cereal rye, vetch, or crimson clover ahead of the planting season leaves a protective biomass mulch layer that suppresses weeds and retains soil moisture. Cover crop termination with a disc mower is demanding work because the crop canopy is typically dense and the machine must operate at field speed to complete the task before planting windows close. A reliable 1000 PTO shaft or 540 PTO shaft that sustains full cutter disc speed without vibration-induced slowdowns or component failures is critical for maintaining the daily output needed during this compressed seasonal operation period.<\/p>\n<p><strong>6. Roadside and Specialty Mowing<\/strong><br \/>\nMaintaining roadsides, drainage ditches, airport buffer strips, and conservation headlands where a clean, controlled cut is needed in irregular or sensitive areas places particular demands on the PTO driveline. The wide-angle CV joints on this PTO shaft for disc mower allow the operator to work the machine at steep lateral offsets and in tight turn-around situations without inducing the vibration and power interruption that occur with straight-shaft designs. The robust PTO shaft guard and safety cone assembly also provides the enclosed, compliant driveline protection required in roadside and public-access environments under local safety codes.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-7018 size-full\" src=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/04\/PTO-Shaft-for-New-Holland-Disc-Mower-5.webp\" alt=\"PTO Shaft for New Holland Disc Mower\" width=\"1200\" height=\"800\" srcset=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/04\/PTO-Shaft-for-New-Holland-Disc-Mower-5.webp 1200w, https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/04\/PTO-Shaft-for-New-Holland-Disc-Mower-5-980x653.webp 980w, https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/04\/PTO-Shaft-for-New-Holland-Disc-Mower-5-480x320.webp 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) and (max-width: 980px) 980px, (min-width: 981px) 1200px, 100vw\" \/><\/p>\n<h2>How to Install PTO Shaft on New Holland Discbine<\/h2>\n<p>1. Safety and Pre-Installation Checks<br \/>\nSebelum memulakan sebarang kerja pemasangan aci PTO, tanggalkan PTO traktor, matikan enjin, dan tanggalkan kunci. Biarkan sebarang komponen yang berputar berhenti sepenuhnya. Sahkan bahawa aci pemacu PTO traktor gantian anda sepadan dengan unit asal dengan membandingkan kiraan dan diameter splin traktor (1-3\/8\u2033 x 21 atau 1-3\/4\u2033 x 20 splin) dengan stub PTO traktor, dan dengan mengesahkan splin alat (1-1\/2\u2033 x 23 splin) dengan aci input cakera. Periksa stub PTO traktor dan aci input alat untuk kakisan, haus splin atau kerosakan sebelum meneruskan. Bersihkan dan griskan kedua-dua titik sambungan dengan sedikit.<\/p>\n<p>2. Verify PTO Shaft Length Before Mounting<br \/>\nWith the tractor hitched to the New Holland 411 discbine in the working position, measure the distance between the tractor PTO stub face and the implement input shaft face. Confirm that the compressed PTO shaft length allows at least 150mm of telescoping overlap between the inner and outer PTO shaft tubing at minimum hitch distance, and that the shaft does not bottom out when the hitch is raised to transport position. If the measured PTO shaft dimensions are outside the rated range, contact CMN Transmission for a custom-length replacement. Incorrect shaft length is one of the most common causes of premature driveline failure.<\/p>\n<p>3. Install the Implement-End Yoke First<br \/>\nMulakan dengan menggeser yoke aci PTO sisi alat (1-1\/2\u2033 x 23 spline) ke atas aci input cakera. Tolak yoke sepenuhnya ke atas spline sehingga gelang snap atau pin pengunci berbunyi klik ke dalam alur lilitan pada aci input. Sahkan penglibatan dengan cuba menarik yoke ke belakang: ia harus menahan penyingkiran dengan kuat tanpa menggunakan butang pelepas. Masukkan rantai sauh pelindung aci PTO ke sekeliling perumah input cakera untuk mengelakkan pelindung daripada berputar bersama dengan aci semasa operasi. Kegagalan untuk menambat rantai pelindung adalah pelanggaran keselamatan dan akan mengakibatkan kerosakan pelindung dan bahaya pembalut.<\/p>\n<p>4. Connect the Tractor-End Yoke and Anchor Guard Chain<br \/>\nSlide the tractor-side yoke onto the tractor PTO stub shaft, aligning the splines carefully and pushing the yoke home until the snap ring engages its groove. For the wide-angle 80-degree CV tractor-end, ensure the CV assembly is oriented so that the wide-angle articulation provides clearance in the direction of maximum tractor-implement articulation during tight turns. Anchor the tractor-end guard chain securely to the tractor drawbar or rear linkage support point. Test the anchor chain tension by pulling the guard laterally; it should be tight enough to prevent rotation but allow the CV assembly to pivot freely.<\/p>\n<p>5. Install Shear Bolts and Verify Fit<br \/>\nInsert the rated PTO shaft shear bolt hardware at both yoke interfaces and tighten to the torque specification listed on the shaft label. Do not substitute alternative grade fasteners for the OEM-specified shear bolt PTO shaft elements; using higher-grade bolts will prevent the overload protection system from functioning and will shift the failure point to the more expensive downstream drivetrain components. Rotate the fully connected PTO driveline shaft by hand through at least two full turns to confirm there is no binding, no guard contact, and smooth telescoping action throughout the range of hitch movement.<\/p>\n<p>6. Run-In and First-Operation Check<br \/>\nEngage the PTO at low engine idle speed in an open area, clear of bystanders, and observe the assembled agricultural PTO shaft for the first 60 seconds of operation. Listen for abnormal vibration, ticking, or guard contact noise. Gradually increase engine speed to operating RPM. After the first 30 minutes of field use, stop the tractor, disengage the PTO, and re-check the yoke snap ring engagement, guard chain anchor points, and shear bolt condition before continuing. Grease the PTO shaft u joint cross-and-bearing assemblies at the specified 8-hour interval during the first season, then follow the routine maintenance schedule in the operator documentation.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-7015 size-full\" src=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/04\/PTO-Shaft-for-New-Holland-Disc-Mower-2.webp\" alt=\"PTO Shaft for New Holland Disc Mower\" width=\"1200\" height=\"760\" srcset=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/04\/PTO-Shaft-for-New-Holland-Disc-Mower-2.webp 1200w, https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/04\/PTO-Shaft-for-New-Holland-Disc-Mower-2-980x621.webp 980w, https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/04\/PTO-Shaft-for-New-Holland-Disc-Mower-2-480x304.webp 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) and (max-width: 980px) 980px, (min-width: 981px) 1200px, 100vw\" \/><\/p>\n<h2>Cara Memilih Aci PTO yang Tepat untuk Mesin Pemotong Cakera<\/h2>\n<p><strong>Step 1: Confirm Your Tractor Spline Profile<\/strong><br \/>\nSebelum memesan sebarang aci PTO traktor, sahkan kiraan spline dan diameter aci stub output PTO traktor anda. Profil paling biasa untuk traktor jarak pertengahan yang mengendalikan New Holland 411 ialah spline 1-3\/8\u2033 x 21 (1.375-21) untuk traktor 35-100 HP, dan spline 1-3\/4\u2033 x 20 (1.750-20) untuk model kuasa kuda yang lebih tinggi. Menggunakan penyesuai aci PTO untuk merapatkan spline yang tidak sepadan adalah mungkin tetapi menambah titik sambungan dan mod kegagalan yang berpotensi. Pendekatan paling selamat adalah dengan memesan aci yang sepadan secara langsung dengan stub traktor anda. CMN menawarkan kedua-dua pilihan spline sebagai konfigurasi standard untuk aplikasi cakera ini.<\/p>\n<p><strong>Step 2: Verify PTO Speed and Shaft Rating<\/strong><br \/>\nConfirm whether your tractor operates the PTO at 540 RPM or 1000 RPM, as indicated by the tractor operator manual and the PTO stub markings. The New Holland 411 disc mower typically operates at 1000 RPM for higher cutting capacity, though some older tractor-discbine combinations use 540 RPM. Both 540 PTO shaft and 1000 RPM PTO shaft configurations are available from CMN Transmission. Running a shaft rated for 540 RPM at 1000 RPM operating speeds will cause premature bearing and yoke failure. If you are uncertain, our technical team can advise based on your tractor model and implement input speed requirements.<\/p>\n<p><strong>Step 3: Measure the Correct Shaft Length<\/strong><br \/>\nUkur jarak tengah ke tengah antara stub PTO traktor dan aci input cakera dengan mesin dipasang pada kedudukan kerja medan biasa. Panjang aci PTO yang bersaiz betul mesti mengekalkan sekurang-kurangnya 150mm pertindihan teleskopik pada jarak kerja minimum (kedudukan terpendek) dan tidak boleh mencapai dasar (mampatan penuh) pada sudut pengangkutan atau pusingan maksimum. Jika jarak yang diukur berada di luar julat undian standard untuk konfigurasi 411, pasukan kejuruteraan CMN Transmission boleh mengeluarkan aci PTO tersuai mengikut dimensi yang anda tetapkan dengan masa tunggu standard selama 7-14 hari bekerja.<\/p>\n<p><strong>Step 4: Select the Appropriate Overload Protection Type<\/strong><br \/>\nFor the New Holland 411 disc mower, the standard overload protection is a shear bolt configuration. The shear bolt PTO shaft design is the most cost-effective option for farms where overload events are infrequent and field-side replacement is straightforward. For operations in rocky or debris-laden fields where overload events occur regularly, a PTO shaft with slip clutch or slip clutch PTO shaft option may be more economical over the full season because the slip clutch resets automatically after an overload event without requiring replacement hardware. CMN Transmission can configure this discbine PTO shaft with either a shear bolt or slip clutch overload system based on your operational requirements.<\/p>\n<p><strong>Step 5: Consider Full Assembly vs. Half Shaft<\/strong><br \/>\nIf only one half of your existing PTO drive shaft for discbine is damaged, consider ordering just the tractor half or implement half as a replacement instead of the full assembly. CMN supplies both tractor-end and implement-end half shafts individually, which can reduce replacement costs significantly when only one CV joint or yoke has failed. The implement half uses a 55N 50-degree CV design, while the tractor half uses the 55N 80-degree wide-angle CV. If both halves show significant wear or if the PTO shaft tube itself is bent or corroded, a full shaft replacement is the more reliable and cost-effective long-term decision.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-7021 size-full\" src=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/04\/PTO-Shaft-for-New-Holland-Disc-Mower-8.webp\" alt=\"PTO Shaft for New Holland Disc Mower\" width=\"1200\" height=\"870\" srcset=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/04\/PTO-Shaft-for-New-Holland-Disc-Mower-8.webp 1200w, https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/04\/PTO-Shaft-for-New-Holland-Disc-Mower-8-980x711.webp 980w, https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/04\/PTO-Shaft-for-New-Holland-Disc-Mower-8-480x348.webp 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) and (max-width: 980px) 980px, (min-width: 981px) 1200px, 100vw\" \/><\/p>\n<h2>Penyelesaian Masalah Biasa Aci PTO Discbine<\/h2>\n<p>1. Problem: Vibration During PTO Operation<br \/>\nPunca dan Penyelesaian: Getaran berlebihan dalam pemasangan aci PTO traktor biasanya disebabkan oleh aci yang tidak sejajar atau bersaiz salah yang melebihi sudut kerja yang dinilai, tiub dalam yang bengkok atau melengkung akibat beban lampau, atau pemasangan silang dan galas sambungan u aci PTO yang haus. Mula-mula sahkan bahawa panjang aci adalah betul dan sudut alat traktor tidak melebihi sudut artikulasi yang dinilai pada sambungan CV pada mana-mana titik dalam laluan pemotongan. Periksa dan gantikan sambungan-U yang haus. Jika tiub itu sendiri cacat secara visual, gantikan pemasangan penuh. Jangan terus beroperasi dengan saluran pacu yang bergetar; kerosakan lesu yang terhasil akan berkembang dengan cepat dan menyebabkan kegagalan aci sepenuhnya.<\/p>\n<p>2. Problem: Shear Bolt Repeated Failure<br \/>\nPunca dan Penyelesaian: Jika bolt ricih aci PTO gagal berulang kali semasa keadaan pemotongan rumput biasa tanpa halangan yang jelas, kemungkinan besar puncanya ialah gred atau saiz bolt yang salah digunakan sebagai pengganti. Hanya gunakan gred dan dimensi bolt yang ditentukan OEM untuk aplikasi aci PTO pin ricih 55N. Punca biasa kedua ialah mengendalikan mesin pemotong rumput ke dalam bahan yang terlalu padat untuk kapasiti undian mesin, yang boleh ditangani dengan mengurangkan kelajuan tanah atau ketinggian cakera pemotong. Di medan berbatu, memasang penaiktarafan aci PTO klac gelincir menghapuskan keperluan penggantian bolt berulang dan membuatkan mesin kembali berfungsi dengan lebih cepat selepas kejadian beban lampau.<\/p>\n<p>3. Problem: Telescoping Stiffness or Seizure<br \/>\nCause and Solution: If the PTO shaft tube or telescoping profile is difficult to slide or has seized, the most frequent cause is dirt, crop debris, or corrosion between the inner and outer tube walls of the PTO shaft tubing. Disassemble the two shaft halves, thoroughly clean the inner and outer profiles with a wire brush and solvent, inspect for scoring or denting of the tube bore, and re-grease with the recommended multi-purpose grease before reassembly. If the inner tube shows visible deformation or if the corrosion has pitted the surface deeply, the tube should be replaced before further operation to prevent the shaft from seizing in the compressed position during a tight turn.<\/p>\n<p>4. Problem: PTO Shaft Guard Damage or Contact<br \/>\nCause and Solution: Damage to the PTO shaft cover or PTO shaft guard is often the result of the anchor chain coming loose, which allows the guard to rotate with the shaft and contact the tractor drawbar or frame. Re-anchor the guard chains at both ends before every field operation. Guards cracked by impact or UV degradation should be replaced immediately; a damaged guard provides inadequate operator protection and fails CE compliance requirements. CMN Transmission supplies replacement guard sets and individual PTO shaft parts for this shaft series. Do not continue operating with a compromised guard, particularly in environments with public access.<\/p>\n<p>5. Problem: Excessive Noise from CV Joints<br \/>\nPunca dan Penyelesaian: Bunyi klik atau kisaran yang terpancar dari kawasan sambungan CV aci pemacu PTO ini untuk cakera biasanya disebabkan oleh pelinciran yang tidak mencukupi dalam pemasangan bebola dan sangkar CV, bebola CV yang haus atau berlubang, atau pengedap but CV yang retak\/rosak yang telah membenarkan pelincir keluar dan pencemaran masuk. Periksa keadaan but CV sebagai sebahagian daripada setiap servis pramusim. But yang koyak atau retak mesti diganti sebelum ia membenarkan kemasukan pasir dan air memusnahkan bahagian dalam CV yang tepat. Jika klik berterusan selepas pelinciran semula, bahagian dalam sambungan CV harus diperiksa dan diganti. Kit penggantian sambungan CV CMN dipadankan secara dimensi dengan siri 55N dan tersedia sebagai bahagian aci PTO individu.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-7019 size-full\" src=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/04\/PTO-Shaft-for-New-Holland-Disc-Mower-6.webp\" alt=\"PTO Shaft for New Holland Disc Mower\" width=\"1200\" height=\"870\" srcset=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/04\/PTO-Shaft-for-New-Holland-Disc-Mower-6.webp 1200w, https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/04\/PTO-Shaft-for-New-Holland-Disc-Mower-6-980x711.webp 980w, https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/04\/PTO-Shaft-for-New-Holland-Disc-Mower-6-480x348.webp 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) and (max-width: 980px) 980px, (min-width: 981px) 1200px, 100vw\" \/><\/p>\n<h2>Aci PTO Pemotong Cakera dan Kotak Gear Pemotong Cakera<\/h2>\n<p>Aci PTO mesin pemotong cakera ialah komponen saluran pacuan luaran yang menghubungkan output pengambilalihan kuasa traktor kepada aci input sistem saluran pacuan utama mesin pemotong cakera. Ia merupakan komponen yang berasingan sepenuhnya daripada sistem kotak gear cakera dalaman, diletakkan di luar antara kedua-dua mesin dan terdedah kepada julat penuh sudut artikulasi alat traktor yang berlaku semasa operasi lapangan, pusingan tanjung dan pengangkutan. Aci PTO untuk model saluran cakera New Holland secara khusus mesti menampung keperluan penghantaran kuasa putaran dan pergerakan sudut lebar yang diperlukan oleh konfigurasi hitch ofset atau bengkok lidah saluran cakera, itulah sebabnya reka bentuk CV berganda CAT 6 ditentukan untuk aplikasi ini dan bukannya aci CV tunggal atau sambungan silang standard yang lebih mudah.<\/p>\n<p>The disc mower gearbox is an enclosed, oil-lubricated gear transmission integrated into the cutterbar of the machine. In the New Holland Discbine design, the cutterbar uses a modular architecture in which each disc module contains its own sealed gear case. These individual gearboxes are connected in series by hardened alloy intermediate drive shafts, allowing the rotary power input from the main bevel gearbox at the cutterbar input end to be distributed sequentially to each disc module along the full cutting width. Each disc module gearbox steps up the input speed to achieve the required disc rotational velocity of approximately 3,000 RPM at the cutter discs themselves. Unlike the external PTO drive shaft for discbine connection, the internal disc gearboxes are maintenance items that require periodic oil changes and seal inspections, but they are designed for long service intervals and operate in a sealed, protected environment.<\/p>\n<p>Aci PTO pemotong cakera dan sistem kotak gear pemotong cakera dalaman saling bergantung secara langsung: kedua-duanya tidak boleh berfungsi tanpa yang lain, dan prestasi serta kebolehpercayaan setiap komponen secara langsung mempengaruhi jangka hayat komponen yang lain. Aci saluran pacu PTO menyampaikan kuasa putar dari PTO traktor ke kotak gear serong utama pada aci input cakera. Kotak gear serong utama kemudian menukar paksi putaran aci sebanyak 90 darjah dan mengagihkan kuasa secara lateral di sepanjang palang pemotong melalui siri kotak gear cakera modular yang saling berkaitan. Jika aci PTO pertanian menghantar getaran atau lonjakan tork ke dalam kotak gear input melalui saluran pacu yang haus atau tidak sejajar, impuls tersebut bergerak melalui keseluruhan rantai kotak gear modular, mempercepatkan haus galas dan keletihan gigi gear merentasi lebar palang pemotong penuh. Sebaliknya, modul kotak gear cakera yang gagal atau terputus mewujudkan peristiwa beban lampau serta-merta dalam saluran pacu yang mesti diserap oleh bolt ricih atau klac gelincir dalam aci PTO traktor untuk melindungi kedua-dua mesin daripada kerosakan lata.<\/p>\n<p>CMN Transmission supplies both the PTO shaft for disc mower applications and the full range of disc mower gearboxes as independent products, allowing agricultural dealers, repair workshops, and farm operators to source both components from a single, certified supplier.

Konfigurasi splin standard ialah sambungan traktor 1-3\/8\u2033 x 21 splin (1.375-21) dengan sambungan alat splin 1-1\/2\u2033 x 23. Varian hujung traktor splin 1-3\/4\u2033 x 20 juga tersedia untuk traktor berkuasa kuda yang lebih tinggi. Sahkan profil splin rintisan PTO traktor anda yang tepat sebelum memesan untuk memastikan padanan langsung. Pasukan teknikal CMN Transmission boleh membantu dengan pengenalpastian splin jika anda tidak pasti.<\/p>\n<p><strong>Q: Is this PTO shaft a direct replacement for the Weasler 55N assembly on the New Holland 411?<\/strong><br \/>\nA: Yes. This shaft is engineered as a direct replacement of Weasler PTO shaft 55N-series assemblies specified for the New Holland 411. The dimensional envelope, spline profiles, CV joint articulation angles, and telescoping tube dimensions are all matched to the OEM specification. No adapters, shimming, or modification to the tractor or discbine are required for installation. The shaft is supplied with a full-length PTO shaft guard assembly compatible with the existing anchor chain attachment points on the New Holland 411 input housing. Batch test reports confirming dimensional compliance with the 55N specification are available upon request.<\/p>\n<p><strong>S: Apakah perbezaan antara aci PTO 540 dan aci PTO 1000 untuk aplikasi mesin pemotong cakera?<\/strong><br \/>\nA: Penamaan aci PTO 540 dan aci PTO 1000 merujuk kepada kelajuan putaran di mana aci output pengangkut kuasa traktor beroperasi. Aci PTO 540 RPM mempunyai stub diameter 1-3\/8\u2033 pada kebanyakan traktor, manakala aci PTO 1000 rpm menggunakan stub diameter 1-3\/4\u2033. Pemotong Cakera New Holland 411 biasanya ditentukan untuk operasi PTO 1000 RPM bagi mencapai kelajuan cakera yang diperlukan, tetapi diameter stub PTO sebenar dan kiraan spline traktor menentukan konfigurasi saiz aci PTO yang anda perlukan. Ketidakpadanan aci dengan kelajuan PTO traktor anda akan mengakibatkan kelajuan cakera yang salah, peningkatan bunyi bising dan kehausan yang dipercepatkan. Transmisi CMN membekalkan konfigurasi yang serasi dengan 540 dan 1000 RPM untuk aplikasi ini.<\/p>\n<p><strong>Q: How do I measure the correct PTO shaft length for my New Holland 411 setup?<\/strong><br \/>\nA: Dengan traktor dan New Holland 411 diikat pada kedudukan medan kerja (bukan pengangkutan), ukur jarak tengah ke tengah antara permukaan stub PTO traktor dan permukaan yoke aci input cakera. Panjang aci PTO yang betul mesti menyediakan pertindihan teleskopik minimum 150mm antara tiub aci PTO dalam dan luar pada jarak kerja minimum ini, dan tidak boleh dimampatkan sepenuhnya (bottom out) apabila gandingan dinaikkan ke ketinggian pengangkutan atau apabila alat dipusingkan ke sudut headland maksimum. Jika ukuran anda berada di luar julat standard, hubungi CMN Transmission dengan dimensi gandingan dan kami akan membekalkan aci PTO tersuai kepada dimensi aci PTO yang anda tentukan.<\/p>\n<p><strong>Q: What is the correct shear bolt grade and size for the 55N series PTO shaft shear bolt protection?<\/strong><br \/>\nA: The PTO shaft shear bolt specification for the 55N series is printed on the shaft label and supplied in the product documentation. Only use the specified bolt grade (typically a mild-grade metric M8 or M10, grade 4.6 or as marked) as the shear bolt PTO shaft protection element. Do not substitute higher-grade (grade 8.8 or above) fasteners: higher-grade bolts will not shear at the design torque limit and will transfer the overload energy to the more expensive downstream components. Replacement PTO shaft parts including shear bolt kits are available individually from CMN Transmission and are commonly stocked by agricultural fastener suppliers worldwide. Always carry a supply of the correct grade bolts in the tractor toolbox during the mowing season.<\/p>\n<p><strong>Q: Can I order a slip clutch PTO shaft version instead of a shear bolt configuration for the New Holland 411?<\/strong><br \/>\nA: Yes. CMN Transmission can supply a PTO shaft with slip clutch or slip clutch PTO shaft configuration for the New Holland 411 application in place of the standard shear bolt design. A slip clutch PTO shaft incorporates a friction disk assembly that slips when torque exceeds the set threshold, then automatically re-engages when the overload condition clears, without requiring any operator intervention or replacement hardware. This is particularly valuable for operations in rocky terrain or dense weed conditions where overload events occur frequently enough to make individual shear pin PTO shaft replacements economically burdensome during the mowing season. Contact our technical team to specify the correct slip clutch torque setting for your tractor and discbine combination.<\/p>\n<p><strong>Q: How often should I grease the PTO shaft u joint and CV assemblies on this discbine driveline?<\/strong><br \/>\nA: For the PTO shaft u joint cross-and-bearing assemblies on this shaft, we recommend greasing with a quality multi-purpose EP (extreme-pressure) grease every 8 hours during the first 50 hours of operation on a new or replacement shaft, then every 20-25 operating hours or at the beginning of each working day thereafter during peak season use. The CV ball-and-cage assemblies are sealed units with their own grease reservoir; they should be inspected at each greasing interval for boot condition and topped up through the CV grease nipple if any boot damage or grease loss is evident. The telescoping PTO shaft tube inner profile should be cleaned and re-greased at the start of each season. Following these intervals maximizes the working life of all the PTO shaft parts in the assembly.<\/p>\n<p><strong>Q: Is the PTO shaft guard (PTO shaft cover) included with the CMN replacement assembly?<\/strong><br \/>\nA: Yes. Every complete PTO shaft assembly from CMN Transmission ships with a full-length high-density polyethylene PTO shaft guard and PTO shaft cover assembly, including both safety cones and the anchor chain hardware. The guard is dimensioned to fit over the full shaft assembly including both CV joint housings at all rated articulation angles without contact. Guard replacement sets and individual cone components are also available separately as PTO shaft parts for operators who need to replace a damaged guard without replacing the complete driveline. All guards meet CE Machinery Directive requirements for PTO driveline guarding and are UV-stabilized for long outdoor service life.<\/p>\n<p><strong>Q: Can CMN Transmission supply a custom PTO shaft for non-standard tractor or implement spline configurations?<\/strong><br \/>\nJ: Ya. Pasukan kejuruteraan CMN Transmission menyediakan perkhidmatan pembuatan aci PTO tersuai penuh untuk aplikasi bukan standard. Ini termasuk profil kuk aci PTO tersuai untuk kiraan atau diameter spline traktor yang luar biasa, konfigurasi penyesuai aci PTO bukan standard untuk aci input alat yang lebih lama atau khusus, dan pembuatan panjang aci PTO tersuai untuk geometri hitch yang berada di luar julat standard. Pesanan tersuai memerlukan pelanggan untuk memberikan spesifikasi stub PTO traktor (diameter, kiraan spline, panjang) dan spesifikasi aci input alat, bersama-sama dengan jarak hitch kerja dan pengangkutan yang diukur. Lukisan dimensi disediakan untuk kelulusan sebelum pengeluaran. Masa utama untuk aci pemacu PTO tersuai biasanya 7-15 hari bekerja bergantung pada kerumitan konfigurasi dan kuantiti.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-7023 size-full\" src=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/04\/PTO-Shaft-for-New-Holland-Disc-Mower-10.webp\" alt=\"PTO Shaft for New Holland Disc Mower\" width=\"1000\" height=\"1000\" srcset=\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/04\/PTO-Shaft-for-New-Holland-Disc-Mower-10.webp 1000w, https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/04\/PTO-Shaft-for-New-Holland-Disc-Mower-10-980x980.webp 980w, https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/04\/PTO-Shaft-for-New-Holland-Disc-Mower-10-480x480.webp 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) and (max-width: 980px) 980px, (min-width: 981px) 1000px, 100vw\" \/><\/p>\n<h2>Ulasan Pelanggan<\/h2>\n<p dir=\"auto\"><strong>Marcus Hollingsworth, Pengurus Ladang, Amerika Syarikat<\/strong><br \/>\n\u201cTelah mengendalikan New Holland 411 di operasi seluas 340 ekar kami di tengah Kansas selama beberapa tahun, dan kami telah melalui beberapa aci PTO sepanjang tempoh itu.

Saya mengesyorkannya tanpa teragak-agak untuk alat ganti.\u201d<\/p>\n<p dir=\"auto\"><strong>Klaus Weber, Kontraktor Pertanian, Jerman<\/strong><br \/>\n\u201cSaya mengendalikan perniagaan kontrak di Bavaria dan bergantung pada alat ganti yang boleh dipercayai. Saya memesan aci sambungan universal CAT-6 (55N 80\u00d750) daripada CMN Transmission untuk mesin pemotong cakera New Holland 411 kami selepas aci Weasler asal mencapai hayat perkhidmatannya selepas kira-kira 5 musim. Harganya jauh lebih rendah daripada pengedar Jerman, namun kualitinya setanding. Tiub pelindung aci pemacu adalah berkualiti HDPE yang kukuh, dan semua sambungan silang dihantar dengan pelincir bersih. Pensijilan CE disertakan dan penting untuk insurans perniagaan kami. Masa penghantaran ke selatan Jerman ialah 11 hari. Saya juga akan terus memesan daripada CMN pada masa hadapan.\u201d<\/p>\n<p dir=\"auto\"><strong>Tyler Mackenzie, Hay Producer, Canada<\/strong><br \/>\n\u201cKami menghasilkan kira-kira 4,000 bal bulat setiap musim dari selatan Ontario, jadi masa henti semasa tempoh pemotongan rumput bukanlah sesuatu yang kami mampu. Saya memesan aci penggantian separuh alat CMN (separuh CV 50 darjah 55N, spline 1.5\u00d723) apabila hanya hujung alat aci 411 kami yang menunjukkan haus. Terima kasih kerana anda boleh memesan separuh sahaja yang anda perlukan dan bukannya pemasangan penuh \u2013 menjimatkan wang sebenar apabila hanya sebahagian daripada aci yang telah siap. Pembungkusan adalah baik, sebahagiannya tiba tanpa kerosakan dalam masa 10 hari ke alamat Ontario kami. Satu-satunya sebab untuk empat bintang dan bukannya lima ialah helaian arahan agak kurang terperinci untuk spesifikasi bolt ricih \u2013 terpaksa menyemaknya sendiri. Aci itu sendiri kukuh, tiada masalah selepas satu musim pemotongan penuh.\u201d<\/p>\n<p dir=\"auto\"><strong>James Whitfield, Estates Farm Manager, United Kingdom<br \/>\n<\/strong> \u201cSaya menguruskan armada kilang untuk operasi pertanian ladang besar di Lincolnshire dan kami memerlukan aci PTO gantian yang berkualiti untuk New Holland 411 kami pada bajet yang berpatutan. Harga pengedar untuk penggantian OEM Weasler terus terang sangat menarik perhatian, jadi saya melihat CMN Transmission sebagai alternatif. Pasukan teknikal mengesahkan keserasian spline untuk traktor John Deere kami (rintisan 1.375-21) sebelum kami membuat pesanan, yang memberi kami keyakinan. Aci tiba dalam keadaan baik, dipasang pada percubaan pertama, dan kami memotong keseluruhan program pemotongan rumput seluas 220 ekar kami pada musim panas ini tanpa satu masalah pun. Kualiti binaan setanding dengan apa yang saya harapkan daripada jenama tier-1. Penjimatan harga adalah besar. Amat disyorkan untuk pembeli armada.\u201d<\/p>\n<p dir=\"auto\"><strong>Pablo Rodriguez, Agricultural Producer, Argentina<\/strong><br \/>\n\u201cSaya membeli aci pengangkut kuasa ini untuk New Holland 411 kami di sebuah estancia di wilayah Buenos Aires, di mana kami memotong kira-kira 600 hektar padang rumput semula jadi setiap musim. Aci Weasler asal patah pada sambungan silang di bahagian traktor selepas enam tahun, dan pengganti rasmi mengambil masa berminggu-minggu untuk tiba disebabkan lokasi kami. CMN Transmission menghantar pemasangan CV berganda 55N 80\u00d750 yang lengkap dalam masa kurang daripada dua minggu terus ke Buenos Aires, yang merupakan kejutan yang sangat positif. Kesesuaiannya tepat, aci gelongsor beroperasi dengan lancar dari jam pertama, dan jaminan selepas jualan telah disahkan secara bertulis. Produk yang sangat baik dan perkhidmatan pelanggan yang cemerlang.\u201d<\/p>\n<p dir=\"auto\"><strong>Declan O'Brien, Petani Tenusu, Ireland<br \/>\n<\/strong> \u201cKami memerah susu 320 ekor lembu di sebuah ladang di County Cork dan 411 merupakan unit pemotongan silaj utama kami. Kami mengendalikan aci pacu asal selama tujuh tahun sebelum ia akhirnya perlu diganti. Kami memilih CMN Transmission berdasarkan cadangan daripada petani lain di kedai-kedai dan benar-benar gembira kerana telah berbuat demikian. Aci CV tugas berat mengendalikan rumput ryegrass padat kami tanpa sebarang rungutan, dan kami tidak mempunyai masalah dengan perlindungan bolt ricih sepanjang musim termasuk satu kejadian di mana kami memotong tepi jalan granit pada pintu pagar. Bolt ricih berfungsi seperti yang sepatutnya \u2013 rosak dengan bersih, mudah diganti, tiada kerosakan lain. Nilai yang baik, kualiti yang boleh dipercayai dan hubungan selepas jualan adalah mesra dan membantu apabila saya menghubungi anda untuk soalan tentang selang masa pelinciran.\u201d<\/p>\n<p dir=\"auto\"><strong>Brad Thompson, Broadacre Farmer, Australia<\/strong><br \/>\n\u201cMenjalankan operasi tanaman luas dan jerami di daerah Riverina, New South Wales. Saya memesan pemasangan aci penuh CMN \u2013 hujung traktor 1.375-21, hujung alat 1.5\u00d723, CV berganda 55N \u2013 untuk New Holland 411 kami. Mengukur semuanya dengan teliti sebelum memesan seperti arahan yang dicadangkan dan acinya meluncur dengan sempurna. Saya agak ragu-ragu tentang kualiti yang datang daripada pembekal dalam talian tetapi ketebalan tiub keluli dan kualiti tempaan yoke kelihatan sama dengan yang asal pada pandangan saya. Pelindung polietilena adalah baik, sauh rantai diperbuat daripada keluli tahan karat dan tidak akan berkarat. Kami telah melakukan sekitar dua musim memotong penuh pada aci, sekitar 240 jam keseluruhan memotong campuran tanaman penutup tanah sub-semanggi, vetch dan rai bijirin. Tiada sebarang kesan padanya. Akan membeli daripada CMN lagi.\u201d<\/p>","protected":false},"excerpt":{"rendered":"<p>Shop CMN Transmission\u2019s heavy-duty PTO shaft for New Holland Discbine 411 disc mower, a precision-engineered CAT 6 constant-velocity agricultural PTO shaft designed as a direct replacement of Weasler PTO shaft assemblies.
