Aci pemacu PTO<\/strong><\/a> for discbine with a true double CV architecture rather than a simpler and cheaper wide-angle shaft.<\/p>\nDuring normal mowing operation, the PTO shaft tractor connection transmits continuous torque to drive the cutterbar discs, the conditioning system (rubber rolls or flail rotor), and the windrow shields. The telescoping PTO shaft tube sections allow the PTO shaft length to vary as the Discbine header rises and falls over uneven terrain and as the tongue angle changes during headland turns. This telescoping action is critical: a PTO shaft that is too short will disengage under extension, while one set too long will bottom out its inner tube and transmit axial force into the CV joints, causing rapid failure. The correct PTO shaft dimensions for the Discbine 1431\/1432 application ensure the shaft operates in the middle of its extension range under normal field conditions, with adequate reserve at both extremes.<\/p>\n
In configurations featuring a PTO shaft with slip clutch or shear bolt PTO shaft protection, the overload device is positioned at the implement input end to interrupt torque transmission before drivetrain damage can occur if the cutterbar encounters a rock, gopher mound, or severe crop blockage. A slip clutch PTO shaft uses a calibrated friction disc that slips at a preset torque, protecting both the shaft and the implement gearbox from shock loads while allowing the machine to resume cutting without stopping to replace a PTO shaft shear bolt. A shear pin PTO shaft design uses a sacrificial bolt or pin that fractures under overload a simple, low-cost protection system that requires the operator to install a replacement PTO shaft shear bolt after each event.<\/p>\n

Applications of PTO Shaft for Disc Mower<\/h2>\n
1. Penuaian Jerami<\/strong>
\nThe primary use case for this PTO shaft for New Holland discbine. The disc mower cuts grasses and legumes into windrows or swaths, while the integrated conditioning rolls crimp and crack the stems to accelerate field drying before baling. The double CV tractor PTO shaft delivers smooth, continuous power through the full cutting width of the 13-foot Discbine 1431\/1432, enabling high field speeds and uniform crop placement essential for quality first-crop hay.<\/p>\n2. Penuaian Makanan Rumput<\/strong>
\nMowing high-value crops such as alfalfa, clover, and ryegrass at the right stage of maturity to maximize nutritional content for livestock feed, whether stored as dry hay or green chop. The PTO driveline shaft for disc mower operations ensures power is delivered without interruption across multiple cuts per season, maintaining consistent disc speed for clean, low-loss cuts that preserve leaf material and maximize forage quality.<\/p>\n3. Pengeluaran Silaj<\/strong>
\nCutting crops at higher moisture levels for fermented silage storage in bunkers, pits, or wrapped bales, where fast, even cutting ensures uniform fermentation. A reliable discbine PTO shaft is critical in silage operations where any downtime represents significant loss of fermentable crop quality. The CAT 6 double CV design handles the torque demands of cutting dense, heavy grass and legume crops at higher field speeds, maintaining throughput in challenging conditions.<\/p>\n4. Pengurusan Padang Rumput<\/strong>
\nTopping and trimming pastures to control rank or stemmy growth, remove weeds, and encourage fresh, palatable re-growth for grazing animals. The agricultural PTO shaft on the Discbine 1431\/1432 efficiently powers the wide cutterbar through varied pasture conditions, including areas with uneven terrain, fire ant mounds, and gopher hills. The center-pivot tongue design allows the mower to follow irregular field boundaries while the double CV PTO drive shaft maintains smooth power delivery at all tongue angles.<\/p>\n5. Penamatan Tanaman Penutup Bumi<\/strong>
\nMenebang tanaman penutup bumi musim sejuk seperti rai bijirin atau vetch sebelum musim penanaman, meninggalkan biojisim sebagai lapisan sungkupan pelindung untuk menyekat rumpai dan melindungi struktur tanah. Aplikasi ini memerlukan aci PTO tugas berat yang teguh yang mampu mengendalikan ketumpatan dan kematangan biojisim tanaman penutup bumi yang berubah-ubah. Aci CAT 6 CMN Transmission menyediakan rizab tork yang diperlukan untuk prestasi yang konsisten walaupun menghadapi tanaman penutup bumi yang tersadai, basah atau padat yang tipikal pada masa penamatan musim bunga.<\/p>\n6. Roadside and Specialty Mowing<\/strong>
\nMaintaining roadsides, drainage ditches, airport buffer strips, and conservation headlands where a clean, controlled cut is needed in irregular or sensitive areas. The double CV PTO driveline shaft of the Discbine excels in these environments where frequent angular changes, stops, and starts are required. The 38.5-degree center-pivot tongue swing allows the Discbine 1431\/1432 to navigate tight corners and obstacles while the tractor PTO drive shaft continues delivering smooth, vibration-free power to the cutterbar.<\/p>\n![\"Aci](\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/04\/PTO-Shaft-for-New-Holland-Discbine-12.webp\")
<\/p>\n
Langkah Pemasangan<\/h2>\n
1. Safety Preparation Before Installation
\nBefore beginning any PTO shaft installation work, shut down the tractor engine completely, engage the parking brake, and wait for all rotating components to come to a full stop. Disconnect the PTO by pulling the engagement lever to the disengaged position. Ensure the tractor key is removed and placed in your pocket to prevent accidental restarting. Lower the Discbine header fully to the ground to relieve hydraulic pressure and prevent unintended movement. Wear appropriate personal protective equipment, including heavy gloves, as PTO shaft yoke edges are sharp and cross kits can have burrs from shipping.<\/p>\n
2. Measure and Record the Original PTO Shaft Length
\nBefore removing the old PTO drive shaft for discbine, measure and record the collapsed length and extended length of the existing shaft assembly in the operating position. This measurement is your reference for setting the new shaft to the correct working length. The correct PTO shaft length should leave at least 1\/3 of the inner tube engaged inside the outer tube when the shaft is at maximum extension, and must not bottom out (compress fully) when the Discbine header is fully lowered. Incorrect PTO shaft dimensions are the most common cause of premature CV joint and telescoping failure.<\/p>\n
3. Remove the Old PTO Shaft Assembly
\nRelease the PTO shaft guard retention chain from the tractor and Discbine anchor points. Depress the tractor-side retention collar button and slide the yoke off the tractor PTO stub shaft. Then release the implement-side collar and slide the yoke off the Discbine input shaft. Remove the old shaft assembly and guard. Inspect the tractor PTO stub and Discbine input shaft for wear, corrosion, or damage to the splines. Clean both shafts with a wire brush and apply a thin film of grease to the splines before installing the new disc mower PTO shaft.<\/p>\n
4. Identify and Prepare the New Shaft Ends
\nLetakkan aci PTO baharu untuk pemasangan cakera New Holland di atas permukaan yang bersih. Kenal pasti hujung traktor (yoke CV 80 darjah, sepadan dengan spesifikasi spline traktor anda) dan hujung alat (yoke CV 50 darjah, spline 1-1\/2\u2033 x 23). Sapukan gris pelbagai guna yang banyak pada kedua-dua spline stub traktor dan aci input alat. Periksa sama ada mekanisme kolar pengunci yoke aci PTO baharu bergerak bebas. Jika peranti beban aci PTO bolt ricih disertakan, sahkan bolt ricih dipasang dengan betul mengikut dokumentasi produk sebelum meneruskan.<\/p>\n
5. Install and Secure Both Shaft Ends
\nStarting with the implement end, align the PTO shaft splines with the Discbine input shaft, slide the yoke on until the retention collar clicks positively into the locking groove. Confirm engagement by attempting to pull the yoke off \u2014 it should not disengage without depressing the collar button. Repeat the installation for the tractor-side yoke, aligning the splines and pushing firmly until the collar locks. Gently pull-test both connections. Anchor the PTO shaft guard retention chains to their respective attachment points on the tractor and Discbine, ensuring the guard does not rotate with the shaft.<\/p>\n
6. Low-Speed Test Run and Final Verification
\nStart the tractor and engage the PTO at low engine speed (900-1000 RPM engine) while standing well clear of the PTO driveline shaft. Observe the shaft for smooth rotation, correct guard alignment, and any signs of vibration or binding. Raise and lower the Discbine header through its full range of motion with the PTO running at low speed to confirm the shaft telescopes freely and maintains engagement throughout. Once satisfied with the low-speed test, increase engine speed to the rated 540 RPM PTO speed and perform a short field test before returning to full production use. Grease all PTO shaft U-joint cross kits before the first field operation.<\/p>\n

<\/p>\n
Maintenance Tip for Discbine PTO Drive Shaft<\/h2>\n
1. Regular Greasing of Cross-and-Bearing Kits<\/strong>
\nGrease all PTO shaft U-joint cross-and-bearing kit Zerk fittings every 8 hours of operation or at least once weekly during active harvesting seasons. Use a quality EP2 multi-purpose grease and pump until fresh grease begins to purge from the bearing seals. Under-greasing of the PTO shaft universal joint assemblies is the single most common cause of premature cross bearing failure on agricultural PTO shafts. Do not use high-pressure grease guns at excessive pressure, as this can blow out the bearing needle roller cups.<\/p>\n2. PTO Shaft Guard Inspection<\/strong>
\nInspect the PTO shaft guard and PTO shaft cover assembly before every use. Look for cracks, missing sections, or damage to the plastic guard halves. Check that the retention chains are intact and firmly anchored. A damaged or missing PTO shaft guard creates a serious operator entanglement hazard and is a regulatory violation in most jurisdictions. Replace any cracked or broken guard sections immediately; CMN Transmission supplies replacement guard parts and components as part of our PTO shaft parts range.<\/p>\n3. PTO Shaft Tube and Spline Lubrication<\/strong>
\nThe telescoping PTO shaft tubing sections should be separated and lubricated at the beginning of each working season and after any prolonged storage period. Separate the two tube sections, clean the inner tube profile and outer tube bore with a brush, and apply a light film of grease before re-engaging. Lubricated PTO shaft tube profiles telescope smoothly throughout the working range, preventing the binding and jerky extension that causes fatigue cracking in the shaft tube walls and damages the CV joints through axial shock loading.<\/p>\n4. U-Joint and CV Joint Play Inspection<\/strong>
\nWith the PTO disengaged and the tractor shut down, manually grasp each yoke on the PTO drive shaft and check for angular play in the PTO shaft U-joint and CV joints by attempting to rock the yoke relative to the adjacent shaft section. Any detectable radial play in the cross bearings indicates wear that will quickly progress to total bearing failure and shaft vibration. Identify and replace worn PTO shaft universal joint cross kits before the season begins to prevent in-field breakdowns at critical harvesting time.<\/p>\n5. Seasonal Storage Preparation<\/strong>
\nAt the end of the harvesting season, disconnect the disc mower PTO shaft from both tractor and implement, clean the shaft and guard assembly thoroughly, and apply a preservative grease to all exposed metal surfaces including the spline yokes and PTO shaft tube profiles. Store the shaft horizontally in a dry, covered location away from UV exposure, which degrades the plastic PTO shaft cover and guard components over time. Using the original packaging or a purpose-made shaft storage bracket prevents the shaft from being stepped on or accidentally run over during storage.<\/p>\n6. Shear Bolt Inspection and Replacement<\/strong>
\nOn units equipped with a shear bolt PTO shaft or shear pin PTO shaft overload protection device, visually inspect the PTO shaft shear bolt at the beginning of each operating day. A shear bolt that has been partially sheared but has not fully fractured provides inadequate overload protection and should be replaced immediately with the correct grade and specification bolt. Never substitute a higher-grade bolt as this defeats the protection function. Always carry a supply of correct replacement shear bolts in the tractor toolbox when operating in rocky or debris-prone fields where overload events are more likely.<\/p>\n![\"Aci](\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/04\/PTO-Shaft-for-New-Holland-Discbine-19.webp\")
<\/p>\n
Penyelesaian Masalah Biasa<\/h2>\n
1. Getaran Berlebihan Semasa Operasi
\nCause: Worn or failed PTO shaft U-joint cross bearings, imbalanced shaft assembly, or incorrect shaft phasing angle. Fix: Check all PTO shaft universal joint cross kits for radial play. Replace worn kits. Verify the two shaft tube sections are assembled with yoke ears in the same plane (correct phasing). If vibration persists with new cross kits, inspect the PTO shaft yoke for cracks or bends and replace if damaged. Verify shaft is not operating at extreme extension or compression throughout the field operation cycle.<\/p>\n
2. CV Joint Binding or Stiff Articulation
\nCause: Insufficient lubrication, contamination of the CV joint internals, or operating beyond the rated angular range. Fix: Grease the CV joint through its dedicated Zerk fitting. If binding persists after greasing, the CV joint internals may be contaminated or scored from previous dry operation. In this case, the CV joint assembly requires replacement. Ensure the Discbine center-pivot tongue does not swing beyond 38.5 degrees during field operation, as exceeding the CV joint angular limit causes internal binding and rapid wear in the PTO drive shaft for discbine.<\/p>\n
3. Unusual Clicking or Knocking Noise
\nCause: Failed or severely worn cross bearing needle rollers, loose yoke collar, or debris caught in the guard assembly. Fix: Stop operation immediately upon noticing unusual noises from the tractor PTO shaft assembly. Disengage PTO, shut down, and inspect all cross kits for needle roller failure (indicated by metallic particles in the grease or visible scoring of the cross pin journals). Replace any failed cross-and-bearing kits. Inspect the PTO shaft guard for contact with the rotating shaft that could indicate guard mounting chain failure. Do not continue operating with a noisy PTO driveline shaft.<\/p>\n
4. Shaft Disengaging from Implement Under Load
\nCause: Worn retention collar locking groove on the implement input shaft or worn collar retention button on the PTO shaft yoke. Fix: Inspect the implement input shaft locking groove for rounding or wear. If the groove is worn, the input shaft may require replacement. Inspect the PTO shaft yoke collar button and spring mechanism; if the spring tension is weak or the button is worn, replace the yoke collar assembly. Never operate with a shaft that is not positively retained on both ends, as disconnection under load creates serious safety and equipment damage risks.<\/p>\n
5. Telescoping Sections Difficult to Extend
\nCause: Corrosion, lack of lubrication, or impact damage to the PTO shaft tube profiles causing binding. Fix: Separate the inner and outer PTO shaft tubing sections, clean the telescoping profiles with a wire brush to remove corrosion and dried grease, then lubricate generously with EP grease before reassembly. If the profile sections have been bent from impact damage, they may need to be replaced. To prevent recurrence, lubricate the profiles at the start of each season and after washing the shaft with a pressure washer, which can strip lubrication from the tube profiles.<\/p>\n
6. Premature Cross Bearing Failure
\nCause: Inadequate greasing intervals, overspeeding (running at 1000 RPM on a 540-rated agricultural PTO shaft), or operating at excessive angular deflection. Fix: Review and increase greasing frequency to a maximum of every 8 operating hours. Confirm the tractor PTO is operating at 540 RPM, not 1000 RPM. Inspect the Discbine tongue angle during operation to confirm it is within the rated angular range of the CV joint. If cross bearing life is consistently short despite correct maintenance, the operating condition (field speed, crop density, terrain) may require upgrading to a higher-series heavy duty PTO shaft.<\/p>\n

Aci PTO Pemotong Cakera dan Kotak Gear Pemotong Cakera<\/h2>\n
Aci PTO mesin pemotong cakera ialah komponen penghantaran kuasa luaran yang menghubungkan traktor ke mesin pemotong cakera atau penyaman mesin pemotong cakera. Dalam konteks New Holland Discbine 1431 dan 1432, aci PTO untuk cakera New Holland ialah pemasangan Halaju Malar Berganda CAT 6 yang memindahkan kuasa putaran daripada aci rintisan PTO traktor pada 540 RPM ke kotak gear input utama alat. Reka bentuk CV berganda adalah unik sesuai untuk aplikasi mesin pemotong cakera potongan lebar kerana ia menghapuskan getaran kilasan dan turun naik kelajuan di bawah pesongan sudut yang besar, yang wujud dalam reka bentuk lidah pangsi tengah mesin ini. Aci PTO traktor ini terdedah kepada unsur-unsur, tertakluk kepada perubahan sudut semasa operasi, dan mesti diselenggara secara rutin dan diganti secara berkala sebagai komponen servis. Transmisi CMN membekalkan rangkaian lengkap bahagian aci PTO termasuk sambungan CV gantian, kit silang, kuk, pelindung dan pemasangan aci penuh untuk mengekalkan kesinambungan operasi sepanjang hayat perkhidmatan alat.<\/p>\n
The disc mower gearbox is the enclosed power distribution system inside the disc mower cutterbar itself. In the New Holland Discbine modular design, this refers to both the main input gearbox (which receives power from the agricultural PTO shaft and distributes it to the cutterbar) and the individual sealed disc module gear cases that step up the speed from the module driveline to the disc speed of approximately 3,000 RPM. Each disc module gear case is individually sealed and lubricated, containing precision-forged bevel and spur gears that convert the relatively low-speed driveline rotation into the high-speed disc rotation required for efficient, clean crop cutting. The disc mower gearbox operates in a continuous enclosed oil bath, is largely maintenance-free between 200-hour oil change intervals, and is designed to be individually replaced if a single module is damaged, without requiring replacement of the entire cutterbar. CMN Transmission manufactures and supplies a complete range of disc mower gearboxes, including center input gearboxes, intermediate module gearboxes, and end module assemblies, compatible with New Holland Discbine and other leading disc mower brands.<\/p>\n
Aci PTO pemotong cakera dan sistem kotak gear pemotong cakera tidak dapat dipisahkan secara fungsinya: satu menyalurkan kuasa kepada mesin, yang satu lagi mengagihkannya melalui mekanisme pemotongan. Antara muka antara keduanya ialah aci input alat, di mana aci PTO untuk kuk pemotong cakera menghubungkan aci input kotak gear palang pemotong utama melalui sambungan spline 1-1\/2\u2033 x 23. Jika aci pemacu PTO menyalurkan kuasa dengan getaran kilasan (seperti aci yang haus atau tidak betul), lonjakan tork kitaran dihantar terus ke dalam galas input kotak gear, memecutkan haus dan berpotensi mematahkan gigi gear. Sebaliknya, galas atau gear input kotak gear yang rosak boleh menyebabkan aci PTO kehabisan penjajaran, memecutkan haus sambungan CV dan galas silang. Inilah sebabnya CMN Transmission mengesyorkan untuk memeriksa kedua-dua aci pemacu PTO dan kotak gear pemotong cakera bersama-sama semasa sebarang acara servis, dan mengapa kami menyimpan kedua-dua rangkaian produk untuk membolehkan perolehan sehenti untuk pelanggan pertanian global kami.<\/p>\n

Soalan Lazim<\/h2>\n
Q: What PTO shaft fits the New Holland Discbine 1431 and 1432?<\/strong>
\nA: Aci PTO yang betul untuk cakera New Holland 1431 dan 1432 ialah aci Halaju Malar Berganda (CV Berganda) CAT 6 yang bersamaan dengan konfigurasi asal Weasler 55N 80\u00d750 darjah. Hujung alat memerlukan yoke spline 1-1\/2\u2033 x 23. Hujung traktor tersedia dalam spline 1-3\/8\u2033 x 21 (untuk kebanyakan traktor utiliti) atau spline 1-3\/4\u2033 x 20 (untuk traktor berkuasa kuda yang lebih tinggi). Kedua-dua model 1431 (penyaman gulungan getah) dan 1432 (penyaman flail) menggunakan aci PTO yang sama untuk spesifikasi mesin pemotong cakera, kerana kedua-duanya berkongsi pemasangan palang pemotong, input kotak gear dan lidah pangsi tengah yang sama.<\/p>\nQ: What does CAT 6 mean for PTO shaft classification?<\/strong>
\nA: CAT 6 refers to the ISO 500 series classification system for agricultural PTO shafts, which categorizes shafts by their torque rating and physical dimensions. The category system runs from CAT 1 (light duty) through CAT 8 (very heavy duty). CAT 6 is a heavy-duty PTO driveline shaft category rated for high-torque implements such as 10-disc to 12-disc wide-cut disc mower-conditioners. The PTO shaft dimensions, tube diameter, wall thickness, yoke size, and cross kit specifications for CAT 6 shafts are standardized under ISO 500, ensuring interchangeability between brands in the same category when correctly specified.<\/p>\nQ: Can I use a 1000 PTO shaft on a New Holland Discbine 1431\/1432?<\/strong>
\nA: Tidak. New Holland Discbine 1431 dan 1432 direka bentuk untuk beroperasi secara eksklusif pada 540 RPM. Menggunakan aci PTO 1000 atau aci PTO 1000 rpm pada model ini akan menyebabkan sistem cakera cutterbar (direka bentuk untuk 3,000 RPM cakera daripada input PTO 540) dan sistem pengkondisian melaju secara berlebihan, menyebabkan kerosakan teruk serta-merta pada drivetrain alat. Sentiasa sahkan pilihan kelajuan PTO traktor anda (kebanyakan traktor moden menawarkan output 540 dan 1000 RPM) dan sahkan ia ditetapkan kepada 540 RPM sebelum menggunakan Discbine. CMN Transmission juga mengeluarkan pemasangan aci PTO 1000 rpm untuk aplikasi alat lain; sila nyatakan kelajuan operasi yang betul semasa membuat pesanan.<\/p>\nQ: Why does a disc mower need a double CV PTO shaft instead of a standard wide-angle shaft?<\/strong>
\nA: The New Holland Discbine 1431\/1432 center-pivot tongue swings up to 38.5 degrees in either direction during field operation. At these large angles, a single wide-angle CV joint still introduces a velocity variation in the power delivery (second-order vibration), causing torque pulses that damage the implement gearbox input bearing and shorten the service life of the PTO shaft universal joint assemblies. A discbine PTO shaft with true double CV geometry uses two complementary CV joints to cancel this velocity variation completely, delivering smooth, constant rotational speed to the Discbine input shaft regardless of tongue angle. This is why the original equipment on the 1431 and 1432 is a double CV shaft, not a simpler single-CV or standard PTO drive shaft.<\/p>\nQ: Is this PTO shaft a direct replacement for the original Weasler unit?<\/strong>
\nJ: Ya. Aci Transmisi CMN ini direka bentuk sebagai pengganti berfungsi aci PTO Weasler kepada spesifikasi CV Berganda CAT 6 siri 55N yang sama. Dimensi splin yoke, sudut sambungan CV (traktor 80 darjah \/ alat 50 darjah), dan geometri aci keseluruhan adalah bersamaan secara dimensi dengan peralatan Weasler yang asal. Saiz aci PTO dan spesifikasi antara muka sepadan dengan keperluan aci input New Holland Discbine 1431 dan 1432. Tiada penyesuai atau pengubahsuaian diperlukan untuk pemasangan. Harga terus kilang CMN Transmission biasanya mewakili penjimatan kos 40-60% berbanding harga penggantian OEM sambil mengekalkan prestasi kejuruteraan yang setara.<\/p>\nQ: Can I order a custom PTO shaft length from CMN Transmission?<\/strong>
\nA: Yes. CMN Transmission offers custom PTO shaft manufacturing for non-standard PTO shaft length requirements. If your tractor-to-implement spacing differs from the standard Discbine configuration due to a drawbar extension, front hitch adapter, or other modification, our engineering team can manufacture a shaft to your specified collapsed and extended length. When requesting a custom PTO shaft, please provide the compressed length (shaft at minimum length), extended length (shaft at maximum operating length), tractor spline, implement spline, CV joint angle requirements, and operating PTO speed. Dimensional drawings are available upon request for pre-order verification.<\/p>\nQ: How do I know when my PTO shaft U-joints need replacing?<\/strong>
\nA: Warning signs that your PTO shaft U-joint or PTO shaft universal joint cross kits need replacement include: noticeable vibration or shuddering during PTO engagement that was not previously present; clicking or knocking sounds from the shaft at operating speed; visible rust staining or metallic debris around the cross bearing caps; any detectable angular play when manually rocking the yoke against the cross pin with the PTO disengaged and the tractor shut down; or cross bearing caps that are visibly cracked, split, or have lost their needle rollers. Do not continue operating with failed cross kits, as secondary damage to the yoke bores makes the repair significantly more expensive. CMN Transmission supplies replacement cross-and-bearing kit assemblies as individual PTO shaft parts.<\/p>\nQ: Does this PTO shaft include a slip clutch overload protection?<\/strong>
\nA: Konfigurasi standard aci PTO pemotong cakera ini tidak termasuk klac gelincir atau peranti beban lampau bolt ricih, kerana New Holland Discbine 1431 dan 1432 menggabungkan perlindungan beban lampau dalam rangkaian pemacu alat itu sendiri. Walau bagaimanapun, jika persekitaran operasi atau keperluan insurans anda memerlukan aci PTO dengan pemasangan aci PTO klac gelincir atau klac gelincir sebagai lapisan perlindungan tambahan, CMN Transmission boleh membekalkan konfigurasi ini. Versi aci PTO klac gelincir menggunakan klac cakera geseran yang dikalibrasi yang tergelincir pada tork pratetap tanpa memerlukan campur tangan pengendali untuk menetapkan semula, menjadikannya sesuai untuk kontraktor volum tinggi yang memotong di ladang dengan batu atau serpihan tersembunyi. Nyatakan keperluan ini semasa membuat pesanan.<\/p>\nQ: How do I properly grease the PTO shaft cross kits and CV joints?<\/strong>
\nA: To grease the PTO shaft U-joint cross-and-bearing kits on your agricultural PTO shaft, locate the Zerk grease fittings on each cross kit (one fitting per cross, typically accessible through the guard). Use a standard grease gun loaded with EP2 multi-purpose grease. Apply steady pressure until fresh grease begins to emerge from the bearing seal lips on all four bearing cups of the cross, confirming that all needle rollers have received fresh lubrication. Do not apply excessive pressure, which can blow out bearing seals. The CV joint center ball assembly should also be greased through its dedicated fitting. Grease intervals: every 8 operating hours during active use, and before any period of storage exceeding two weeks.<\/p>\nQ: What tractor horsepower is required to run the Discbine 1431\/1432 with this PTO shaft?<\/strong>
\nA: New Holland Discbine 1431 dan 1432 ialah mesin pemotong rumput 10-cakera, selebar 13 kaki yang dinyatakan oleh New Holland memerlukan kira-kira 80-100 kuasa kuda PTO untuk prestasi optimum. Aci PTO tugas berat Transmisi CMN CAT 6 ini dinilai untuk beban tork yang berkaitan dengan julat kuasa kuda ini. Aci PTO traktor dan pemasangan aci pemacu PTO traktor direka bentuk untuk menghantar kuasa penuh traktor kelas 100 HP secara berterusan tanpa terlalu panas atau kegagalan keletihan di bawah keadaan operasi biasa. Menggunakan traktor dengan kurang daripada 80 PTO HP boleh mengakibatkan prestasi rendah dalam keadaan tanaman yang padat atau basah, tetapi tidak akan merosakkan aci. Sentiasa pilih pilihan spline traktor yang betul (1-3\/8\u2033 x 21 atau 1-3\/4\u2033 x 20) agar sepadan dengan aci stub PTO traktor anda.<\/p>\n![\"Aci](\"https:\/\/korea-transmission.com\/wp-content\/uploads\/2026\/04\/PTO-Shaft-for-New-Holland-Discbine-18.webp\")

Kami telah mendapatkan alat ganti Weasler melalui pengedar tempatan sebelum ini tetapi harganya terus meningkat. Memberi CMN Transmission cadangan daripada kontraktor lain. Memesan dua aci CV berganda CAT 6 lengkap \u2013 satu dengan 1-3\/8 x 21 dan satu dengan spline traktor 1-3\/4 x 20 agar sesuai dengan traktor kami yang berbeza, kedua-duanya dengan hujung alat 1-1\/2 x 23. Kedua-duanya muat buat kali pertama tanpa sebarang masalah. Mengendalikannya sepanjang musim pemotongan penuh \u2013 kira-kira 400 jam gabungan \u2013 dan ia bertahan dengan sangat baik. Tiub aci PTO diperbuat daripada keluli padu, bukan sampah berdinding nipis. Pelanggan gembira, akan memesan lebih banyak mengikut keperluan.\u201d<\/p>\nKlaus Hoffmann, Dairy Farmer, Germany<\/strong>
\n\u201cKami menjalankan operasi tenusu seluas 180 hektar di Bavaria dan menggunakan New Holland Discbine 1432 untuk kerja silaj rumput kami. Apabila aci PTO asal haus selepas lima musim penggunaan berat, saya menghubungi CMN Transmission dan pasukan teknikal mereka benar-benar membantu dalam mengesahkan konfigurasi CV dan spesifikasi spline yang betul untuk traktor Fendt saya. Aci PTO pertanian CV berganda CAT 6 yang mereka bekalkan sepadan dengan sempurna \u2013 sudut CV 80\u00d750 darjah dan spline alat 1-1\/2 x 23 terpasang dengan bersih. Kualiti binaan kukuh dan pemasangan pelindungnya kukuh. Penghantaran ke Jerman mengambil masa kira-kira 12 hari bekerja yang boleh diterima. Harganya jauh lebih rendah daripada yang dipetik oleh pengedar New Holland tempatan saya untuk penggantian OEM. Sejak itu, kami telah meluangkan lebih 300 jam untuk memotong campuran rumput dan kekacang tanpa sebarang masalah langsung. Akan memesan lagi tanpa teragak-agak.\u201d<\/p>\nPierre Morisset, Livestock Farmer, France<\/strong>
\n\u201cSaya menguruskan ladang lembu pedaging di Brittany dengan kira-kira 140 hektar padang rumput kekal, dan New Holland 1431 kami mengalami kerosakan teruk setiap tahun memotong rumput pantai yang tebal dan basah. Aci pemacu PTO traktor asal mula menunjukkan kecondongan pada sambungan-U selepas kira-kira tiga musim. Seorang rakan petani menunjukkan saya ke arah Transmisi CMN dan saya sangat gembira dia berbuat demikian. Saya menyatakan hujung traktor 1-3\/8 x 21 dan hujung alat 1-1\/2 x 23, mengesahkan konfigurasi CV berganda adalah betul, dan membuat pesanan. Aci tiba dalam masa kira-kira 10 hari. Pemasangan adalah mudah dan kurang daripada sejam. Dimensi aci PTO adalah tepat, kuk dipasangkan dengan bersih, dan sambungan CV bersendi dengan lancar melalui julat stereng penuh lidah pangsi tengah Discbine. Sangat berpuas hati dengan kualiti dan nilainya. Penghantaran lebih cepat daripada yang saya jangkakan.\u201d<\/p>\nWilliam Hargreaves, Grassland Farmer, United Kingdom<\/strong>
\n\u201cBertani kira-kira 350 ekar tanah pertanian campuran dan padang rumput di Yorkshire. Kami memotong jerami dan rumput kering dengan New Holland 1432 di belakang New Holland T6. Aci pemacu PTO asal mula mengetuk pada musim bunga lalu \u2013 mendiagnosisnya sebagai sambungan-U yang haus. Daripada membayar harga pengedar, saya mendapatkan aci PTO pemotong cakera gantian lengkap daripada CMN Transmission. Memesan unit CV berganda CAT 6 dengan spline traktor 1-3\/4 x 20 dan spline alat 1-1\/2 x 23. Tiba dalam masa seminggu di ladang kami. Pemasangannya bersih dan mudah. \u200b\u200bTolok tiub aci PTO adalah baik; pelindung meliputi keseluruhan panjang kerja dengan betul. Jalankannya melalui tiga potongan rumput rye dan semanggi tahun ini tanpa masalah. Satu-satunya perkara kecil yang saya perhatikan ialah arahan pemasangan boleh diperincikan dengan lebih terperinci \u2013 tetapi pemasangan itu sendiri tidak menyusahkan. Harganya sangat kompetitif berbanding harga pengedar UK. Akan memesan daripada CMN lagi.\u201d<\/p>\nShane O'Brien, Kontraktor Hay, New Zealand<\/strong>
\n\u201cKami melakukan pemotongan dan pengepakan rumput secara kontrak merentasi Canterbury Plains, mengendalikan dua New Holland Discbine \u2013 sebuah 1431 dan sebuah 1432. Setahu saya, apabila anda menggunakan mesin selama lebih 800 jam setiap musim, bahagian aci PTO adalah bahan habis pakai. Menemui CMN Transmission melalui carian dalam talian apabila saya memerlukan aci PTO pertanian gantian untuk 1431. Saya ragu-ragu untuk memesan dari luar negara tetapi penghantarannya lebih cepat daripada yang dijangkakan dan spesifikasi aci adalah tepat \u2013 CAT 6 CV berganda, hujung traktor spline 1-3\/8 x 21, hujung alat 1-1\/2 x 23. Padanannya sempurna pada traktor PTO 540 kami. Kualitinya setanding dengan unit Weasler asal yang pernah saya gunakan sebelum ini, dan harganya jauh lebih rendah. Pelindung aci PTO terasa tahan lama dan puting gris pada kit silang mudah diakses. Telah membuat pesanan kedua.\u201d<\/p>\nCarlos Eduardo Ferreira, Ranch Owner, Brazil<\/strong>
\n\u201cKami mengendalikan ladang seluas 500 hektar di negeri Sao Paulo yang menanam tanaman jerami dan silaj, dan New Holland Discbine 1432 kami merupakan tulang belakang operasi makanan ternakan kami. Apabila aci pemacu PTO asal mula menunjukkan haus pada galas silang selepas dua musim pemotongan berat padang rumput dan sorgum bersebelahan tebu, saya mencari dalam talian dan menemui Transmisi CMN. Pasukan teknikal mereka mengesahkan spesifikasi yang betul \u2013 CV berganda CAT 6, spline alat 1-1\/2 x 23 \u2013 dan aci tiba dalam masa kira-kira 14 hari. Penglibatan yoke aci PTO adalah ketat dan betul, tiada masalah langsung. Kami kini telah menyelesaikan dua musim silaj penuh pada aci ini dan ia tahan lama. Harganya sangat kompetitif berbanding dengan mengimport alat ganti OEM. Amat mengesyorkan Transmisi CMN untuk sesiapa sahaja yang memerlukan alat ganti aci PTO berkualiti pada harga yang berpatutan.\u201d<\/p>\nRoberto Alejandro Guzman, Forage Contractor, Argentina<\/strong>
\n\u201cSaya bekerja sebagai kontraktor makanan ternakan di wilayah Pampas, Argentina, memotong alfalfa, ryegrass dan sorgum untuk operasi ternakan tempatan. Salah satu mesin saya ialah New Holland Discbine 1431, dan apabila aci PTO asal akhirnya rosak selepas bertahun-tahun bekerja keras, seorang rakan sekerja yang telah membeli daripada CMN Transmission mengesyorkannya. Saya memesan aci PTO tugas berat dengan spline traktor 1-3\/8 x 21 dan hujung alat 1-1\/2 x 23. Penghantaran ke Argentina mengambil masa kira-kira 18 hari yang berpatutan. Aci itu sendiri dibina dengan baik \u2013 reka bentuk CV berganda mengendalikan artikulasi lidah pangsi tengah Discbine tanpa sebarang getaran atau pengikatan yang saya dapat kesan. Penutup dan pelindung aci PTO kukuh dan memenuhi piawaian keselamatan. Selepas satu musim alfalfa penuh dengan aci ini, saya berpuas hati dengan pelaburannya. Kualiti yang baik, harga yang jujur, disyorkan.\u201d<\/p>","protected":false},"excerpt":{"rendered":"Looking for a reliable replacement PTO shaft for New Holland Discbine 1431 or 1432 disc mower?
