Features of PTO Drive Shaft for Jaylor Feed Mixer
1. Precision-Machined PTO Shaft Yoke
Every PTO shaft yoke on both the tractor and implement ends is forged from alloy steel and finish-machined to DIN 808 tolerances. Bearing cup bores are held to a tolerance of plus or minus 0.012 mm, which eliminates the radial play that causes premature needle bearing failure in high-vibration environments typical of twin auger feed mixer operations. Each yoke fork is CMM-inspected before assembly to guarantee dimensional accuracy.
2. Integroitu liukukytkimen suojaus
The built-in PTO shaft with slip clutch mechanism provides critical overload protection for both the tractor drivetrain and mixer gearbox. When the twin augers encounter a sudden overload from a frozen bale or foreign object in the feed, the multi-disc friction slip clutch PTO shaft disengages momentarily to absorb the shock, preventing catastrophic damage to the PTO driveline shaft, gearbox internals, and tractor transmission.
3. Heavy Duty Cross-and-Bearing U-Joints
Each PTO shaft u joint uses a full-complement needle bearing design with case-hardened cross trunnions and high-temperature grease fill. The PTO shaft universal joint assemblies are rated for continuous 1000 RPM operation at operating angles up to 25 degrees, ensuring smooth torque delivery even when the tractor and mixer are not perfectly aligned on uneven farmyard surfaces or during turns at the feed bunk.
4. Cold-Drawn Steel PTO Shaft Tubing
The inner and outer PTO shaft tube assemblies are cold-drawn from high-carbon steel and profiled in a lemon or triangular cross-section to maximize torque transfer while allowing the shaft to telescope freely. This PTO shaft tubing design prevents rotational play between inner and outer sections, a common wear mechanism in lower-cost aftermarket shafts. The precision-ground outer profile ensures smooth sliding with minimal friction heating during telescoping cycles.
5. Full-Length Safety Guard System
A complete PTO shaft guard and PTO shaft cover system encases the entire rotating assembly. The free-spinning plastic guard shields the rotating PTO drive shafts from accidental contact, protecting operators and bystanders. The guard bearing design allows the cover to remain stationary while the shaft spins at full 1000 RPM speed, and it can be removed quickly for maintenance access without special tools.
6. Shear Bolt Option Available
For operations that prefer a sacrificial protection system, this PTO shaft for Jaylor feed mixer is also available with a PTO shaft shear bolt configuration. The shear bolt PTO shaft uses calibrated shear pins that break cleanly at a predetermined torque threshold, providing positive overload protection and allowing quick field replacement. This shear pin PTO shaft option is ideal for operators who want the simplest possible protection mechanism for their feed mixer driveline.
7. Direct-Fit OEM Replacement
This heavy duty PTO shaft is engineered as a direct-fit replacement of Bondioli & Pavesi PTO shaft assemblies originally supplied with Jaylor twin auger TMR mixers. The PTO shaft dimensions, spline profiles, and yoke geometry match original equipment specifications exactly, so no PTO shaft adapter or modification is needed. Simply remove the old shaft and install the CMN replacement to get back to mixing.
8. Customizable Length and Configuration
CMN Transmission offers this as a custom PTO shaft solution, with adjustable PTO shaft length and multiple PTO shaft sizes to match your specific tractor-to-mixer distance. Whether your setup requires a compact 900mm center-to-center shaft or a longer 1500mm assembly, we manufacture each unit to your exact measurements. Multiple spline and clutch combinations are available to ensure perfect compatibility with your equipment.

How the Tractor PTO Shaft for Jaylor TMR Mixer Works
The operating principle of a PTO shaft for Jaylor twin auger TMR mixers begins at the tractor's rear power take-off stub. The tractor engine generates rotational energy, and the PTO output transmits this energy at a standardized 1000 RPM PTO shaft speed of 1,000 revolutions per minute. The female splined hub on the tractor end of the PTO driveline shaft engages with the male spline on the tractor's PTO stub, creating a secure rotational coupling that transfers engine torque directly into the shaft assembly.
Once engaged, the rotational force travels through the first PTO shaft universal joint at the tractor end. This cross-and-bearing assembly allows the shaft to operate at an angle relative to the tractor's PTO output axis, which is necessary because the Jaylor TMR mixer's input shaft is rarely perfectly aligned with the tractor's PTO during operation. The universal joint accommodates angular misalignment of up to 25 degrees while maintaining continuous torque transfer. As the shaft rotates, the torque passes through the outer PTO shaft tube, which is telescopically connected to the inner tube via a profiled lemon or triangular cross-section.
This telescoping mechanism is critical for vertical feed mixer PTO shaft applications because the distance between the tractor and the TMR mixer changes constantly as the operator maneuvers around the feed storage area, backs up to the bunk, or turns corners during the feeding route. The profiled tubes slide freely in and out while maintaining a positive rotational lock, ensuring that 100% of the torque is transmitted regardless of shaft extension length. Unlike round profile tubes used in some economy drivelines, the multi-lobe geometry eliminates rotational backlash that would create vibration and accelerated wear.
At the implement end, the rotational energy passes through the second PTO shaft u joint and into the mixer's input shaft. Before reaching the gearbox, the torque passes through the overload protection device, either a slip clutch PTO shaft mechanism or a shear bolt PTO shaft system. The slip clutch uses spring-loaded friction discs that allow controlled slippage when torque exceeds the preset threshold. This protects the mixer's planetary gearbox, auger bearings, and the tractor's own PTO drivetrain from damage caused by sudden overloads, such as a frozen bale core or a piece of wire baling twine wrapping around an auger flight.
The Jaylor mixer's planetary gearbox receives the 1000 RPM input and reduces it to the appropriate auger speed, typically between 20 and 40 RPM depending on the model and mixing stage. The twin augers rotate in opposite directions, pulling feed material downward at the center of the tub and pushing it upward along the outer walls. This continuous circulation pattern is what produces the uniform, sort-resistant TMR that Jaylor mixers are known for. Throughout this entire process, the PTO drive shaft for feed mixer operation must deliver consistent, vibration-free torque to maintain smooth auger rotation and prevent the pulsating loads that can damage gearbox seals and bearings over time.

Applications of Feed Mixer PTO Shaft
1. Dairy Farms
Dairy operations depend on consistent TMR quality to maintain milk production, butterfat percentages, and overall herd health.

How to Install PTO Shaft on Your Jaylor TMR Mixer
Vaihe 1: Turvallisuusvalmistelut
Before beginning any installation work on the PTO shaft for Jaylor twin auger TMR mixers, park the tractor on level ground and set the transmission to PARK or place it in gear with the parking brake fully engaged. Shut off the engine and remove the ignition key. Wait for all rotating components to come to a complete stop. Never work on or near a PTO drive shaft with the engine running. Wear close-fitting clothing, safety gloves, and eye protection. Ensure no bystanders are within the operating zone of the tractor or mixer.
Vaihe 2: Irrota vanha nivelakseli
If you are replacing an existing shaft, disconnect the old tractor PTO shaft from the tractor's PTO stub first. Locate the locking collar or push-pin mechanism on the tractor-end PTO shaft yoke. Press the release button or pull the locking pin while gently sliding the yoke rearward off the splined stub shaft. Then disconnect the implement end from the Jaylor mixer's input shaft using the same method. Support the shaft with both hands during removal because a complete PTO driveline shaft assembly is heavy, typically 15 to 25 kg depending on the category size. Set the old shaft aside for inspection or disposal.
Step 3: Verify Length and Fitment
Before installing the new CMN Transmission PTO shaft for Jaylor feed mixer, verify the PTO shaft length and PTO shaft dimensions match your application. Extend the telescoping tubes to their maximum length and compare the center-to-center distance with the actual distance between the tractor PTO stub and the mixer input shaft when the tractor and mixer are positioned at maximum working separation. The PTO shaft tube overlap must remain at least 150mm (6 inches) at full extension to prevent the inner and outer tubes from separating during operation. If the shaft is too long, it may bottom out when the tractor is close to the mixer; if too short, it could pull apart at full extension.
Step 4: Connect the Implement End First
Align the implement-side PTO shaft yoke with the Jaylor mixer's input shaft. Slide the splined connection onto the mixer's input stub and push firmly until the locking mechanism engages with an audible click. Verify that the shaft is locked by attempting to pull it back off. The shaft should not come free without pressing the release mechanism. If your configuration includes the PTO shaft with slip clutch, the clutch assembly should be positioned on the implement side of the shaft, closest to the mixer.
Step 5: Connect the Tractor End
With the implement end secured, carefully align the tractor-side splined yoke with the tractor's 1000 RPM PTO shaft stub. The 1-3/8" 21-spline profile will only engage in the correct alignment. Slide the yoke onto the stub shaft until the locking collar snaps into position. Verify the lock is fully engaged. Secure the PTO shaft guard retaining chains to both the tractor drawbar and the mixer frame to prevent the guard from rotating with the shaft.
Step 6: Test and Verify
Start the tractor engine and slowly engage the PTO at low idle speed. Observe the PTO shaft for any unusual vibration, wobble, or noise. Gradually increase to full operating speed (1000 RPM). Check that the PTO shaft cover remains stationary and that neither end connection shows any sign of looseness. Run the mixer empty for two to three minutes to confirm smooth operation before loading feed material. After the first hour of operation, shut down and re-check all connections, grease all PTO shaft u joint fittings, and inspect the slip clutch or shear bolt PTO shaft mechanism for proper function.

How to Choose the Right PTO Drive Shaft for Feed Mixer
1. Confirm PTO Speed (540 vs. 1000 RPM)
The Jaylor 6000 Series twin auger models (6600, 6650, 6750, 6850) operate on a 1000 RPM PTO shaft standard. Check your tractor's PTO output specification before ordering. A 1000 RPM PTO stub typically features a 1-3/8" 21-spline profile, whereas a 540 PTO shaft uses a 1-3/8" 6-spline profile. Connecting a 1000 RPM shaft to a 540 RPM PTO or vice versa will result in incorrect auger speed and potential equipment damage.
2. Determine the Correct Shaft Category
Different PTO shaft sizes handle different torque loads. For the Jaylor 6600 and 6650 models, a CAT4 (Size 6) shaft is typically sufficient. Larger models like the 6750 and 6850 may require a CAT6 (Size 8) shaft to handle the higher torque demands of larger tub volumes and heavier feed loads. Choosing the correct category ensures the PTO drive shaft operates within its rated capacity, preventing premature failure from under-specification.
3. Measure the Required Shaft Length
Measure the center-to-center distance between the tractor PTO stub and the mixer input shaft in both the closest and farthest working positions. The PTO shaft length must accommodate both extremes with adequate tube overlap (minimum 150mm). CMN Transmission manufactures custom PTO shaft assemblies to your specific measurements, so provide both minimum and maximum distances when ordering to ensure perfect fitment.
4. Select the Overload Protection Type
Choose between a slip clutch PTO shaft and a shear bolt PTO shaft based on your operational preferences. The slip clutch offers automatic, resettable protection and is ideal for operations mixing abrasive or variable-density feed ingredients daily. The PTO shaft shear bolt option is simpler and less expensive but requires replacement pins after each overload event. For high-frequency commercial mixing, the slip clutch is the recommended choice.
5. Verify Spline Compatibility
Check both the tractor-side and implement-side spline profiles. Most 1000 RPM tractors use a 1-3/8" 21-spline PTO stub. The implement side connecting to the Jaylor mixer input may be 1-3/8" 21-spline or 1-3/4" 20-spline depending on the mixer model and year. If your configuration requires a different spline on either end, CMN Transmission can supply the correct PTO shaft adapter or custom yoke to match.
6. Consider Your Operating Environment
If you operate in dusty, wet, or corrosive conditions such as near silage pits, manure storage, or coastal environments, request the enhanced surface treatment option with zinc plating on all critical surfaces. For operations mixing multiple batches daily with minimal downtime, the heavy duty PTO shaft with the highest clutch torque rating (1800 Nm) provides additional reserve capacity and longer service intervals between adjustments.

Common Troubleshooting for Feed Mixer PTO Shaft Issues
1. Liiallinen tärinä käytön aikana
If you notice unusual vibration while the PTO shaft is running, the most common causes are worn PTO shaft u joint cross bearings, misaligned yoke phasing, or insufficient tube overlap. Begin by shutting down the tractor and inspecting each PTO shaft universal joint for play. Grip each yoke near the cross bearing and try to rock it. Any detectable movement indicates the cross bearing kit needs replacement. Next, verify that both yoke forks on the same side of the shaft are aligned in the same rotational plane (proper phasing). Misphased yokes create a sinusoidal vibration that intensifies at higher RPM. Finally, check that the inner and outer PTO shaft tube sections maintain at least 150mm of overlap; insufficient overlap allows lateral deflection that manifests as vibration.
2. Slip Clutch Engages Too Frequently
If your slip clutch PTO shaft is slipping during normal mixing loads, the friction disc springs may have weakened or the disc surfaces may be glazed from heat. Remove the clutch assembly and inspect the friction plates for glazing, scoring, or reduced thickness. If the plates appear serviceable, adjust the spring preload according to the clutch manufacturer's specification to restore the correct engagement torque. If the discs are glazed or worn below minimum thickness, replace the entire friction pack. Also verify that you are not exceeding the mixer's rated batch weight, which can overload even a properly adjusted clutch.
3. Shaft Difficult to Telescope
When the PTO shaft tubing becomes difficult to slide in or out, the most likely cause is lack of lubrication on the slip profile surfaces, or corrosion buildup from exposure to silage acids and moisture. Disconnect the shaft from both the tractor and mixer. Separate the inner and outer tubes, clean the profile surfaces thoroughly with a wire brush, and apply a generous coating of anti-seize or PTO shaft slip profile grease. Reassemble and verify smooth telescoping action across the full range of travel. If the tubes are scored or corroded beyond cleaning, replacement PTO shaft tube components are available from CMN Transmission.
4. Shear Bolts Breaking Repeatedly
Frequent PTO shaft shear bolt failure indicates either an overload condition within the mixer or incorrect shear bolt grade. First, inspect the mixer tub for foreign objects such as wire, metal fragments, or frozen feed masses that may be overloading the auger system. Check that the auger knives are sharp and the tub liner is not excessively worn, both of which increase mixing resistance. If the mixer is mechanically sound, verify that you are using the correct grade of shear pin PTO shaft bolts as specified by CMN Transmission. Using bolts from a hardware store with unknown shear strength will result in either premature failure or, worse, failure to shear under overload, risking damage to the gearbox.
5. Epätavallinen ääni murtosovitteista
Clicking, popping, or grinding sounds from the PTO shaft u joint area indicate bearing failure or inadequate lubrication. Grease all PTO shaft universal joint fittings every 8 operating hours using a high-quality EP2 lithium grease. Pump grease until fresh lubricant appears at all four bearing cap seals. If noise persists after greasing, the cross bearing has likely failed internally and must be replaced. CMN Transmission supplies replacement cross-and-bearing kits matched to each shaft category, ensuring correct fit and bearing capacity for the 1000 rpm PTO shaft operating speed of Jaylor twin auger TMR mixers.

Feed Mixer PTO Shaft and Feed Mixer Gearbox
The feed mixer PTO shaft and the feed mixer gearbox are the two most critical power transmission components in any TMR mixing system, and they must work in concert for the mixer to operate reliably and efficiently. The PTO drive shaft for feed mixer serves as the external mechanical link that transfers rotational energy from the tractor's power take-off output to the mixer. It handles the variable geometry between tractor and mixer through its telescoping tube design and PTO shaft universal joint assemblies, while simultaneously providing overload protection through its integrated slip clutch PTO shaft or shear bolt PTO shaft mechanism. Without a properly functioning PTO shaft, the mixer's gearbox receives no input power and the augers cannot rotate.
The feed mixer gearbox, mounted internally on the mixer frame, receives the rotational input from the PTO driveline shaft and converts it into the specific speed and torque outputs required to drive the mixer's auger or augers. In Jaylor twin auger TMR mixers, the gearbox is a planetary gear system that performs two essential functions: it reduces the 1000 RPM input from the 1000 RPM PTO shaft down to the 20-40 RPM range required for effective auger rotation, and it redirects the rotational axis from the horizontal PTO input to the vertical auger shafts. This right-angle speed reduction and directional change would be impossible without a properly engineered gearbox.
The relationship between the PTO shaft for TMR feed mixer and the gearbox is symbiotic. If the PTO shaft delivers inconsistent or pulsating torque due to worn PTO shaft u joint bearings, misphased yokes, or damaged PTO shaft tubing, the gearbox bearings and seals absorb those vibrations and wear out prematurely. Conversely, if the gearbox develops internal problems such as worn planet gears or damaged bearings, the resulting resistance spikes are transmitted back through the shaft, overloading the PTO shaft universal joint assemblies and accelerating their failure. This is why CMN Transmission recommends inspecting both the PTO shaft and the gearbox together whenever either component shows signs of wear.
CMN Transmission supplies both feed mixer PTO shaft assemblies and feed mixer gearbox units for Jaylor and other major TMR mixer brands. By sourcing both components from a single manufacturer, you ensure that the shaft's torque output characteristics precisely match the gearbox's input requirements, eliminating compatibility issues that can arise when mixing parts from different suppliers. Whether you need a complete PTO shaft for Jaylor feed mixer replacement, a standalone gearbox rebuild, or both components as a matched set, CMN Transmission provides the engineering expertise and manufacturing capability to keep your mixing operation running at peak efficiency.

K: Kuinka usein minun pitäisi voidella rehunsekoittimeni voimanottoakselin nivelet?
A: CMN Transmission suosittelee kaikkien nivelten voitelua 8 käyttötunnin välein tai jokaisen työpäivän alussa ruuhka-aikaan. Käytä korkealaatuista EP2-litiumpohjaista rasvaa ja pumppaa, kunnes tuoretta rasvaa ilmestyy kaikkien neljän laakerikannen tiivisteisiin kussakin nivelessä. Säännöllinen voitelu on tärkein huoltovaihe traktorin nivelakselin käyttöiän pidentämiseksi ja kalliiden poikittaislaakerivaurioiden estämiseksi.
K: Voinko käyttää 540 rpm:n nivelakselia Jaylor 6750 TMR -sekoittimessani?
V: Ei. Jaylor 6750 (ja kaikki 6000-sarjan kaksoisruuvimallit: 6600, 6650, 6750, 6850) on suunniteltu käytettäväksi 1000 rpm:n voimanottoakselilla. 540 rpm:n voimanottoakselin käyttö johtaisi siihen, että ruuvit pyörisivät noin puolella aiotusta nopeudesta, mikä johtaisi huonoon seoksen laatuun, pidempiin sekoitusaikoihin ja vaihteiston mahdolliseen ylikuormitukseen. Sovita voimanottoakselin nopeus aina sekoittimen syöttöspesifikaatioon.
K: Mikä on tämän kokoonpanon voimanottoakselin ristinivelten suurin sallittu käyttökulma?
A: Tämän raskaaseen käyttöön tarkoitetun nivelakselin nivelkokoonpanot on mitoitettu jatkuvaan käyttöön jopa 25 asteen kulmissa. Parhaan tuloksen ja laakerin pisimmän käyttöiän saavuttamiseksi CMN Transmission suosittelee pitämään käyttökulman alle 15 astetta jatkuvan sekoitustoiminnan aikana. Liialliset kulmat kiihdyttävät nivelen kulumista ja aiheuttavat syklisiä nopeusvaihteluita, jotka lisäävät tärinää koko voimansiirrossa.
K: Voiko CMN Transmission valmistaa mittatilaustyönä voimanottoakselin juuri minun traktoriini ja sekoittimeeni sopivaksi?
A: Ehdottomasti. CMN Transmission on erikoistunut mittatilaustyönä tehtyjen voimanottoakseleiden valmistukseen. Anna vain traktorisi voimanottoakselin ja Jaylor-sekoittimen sisääntuloakselin välinen vähimmäis- ja enimmäisetäisyys keskeltä keskelle, niin suunnittelutiimimme valmistaa akselin, jolla on optimaalinen kokoontaitettu pituus ja teleskooppialue. Saatavilla on myös räätälöityjä ura- ja kytkimen vääntömomenttiarvoja, jotka sopivat mihin tahansa traktori-sekoitinyhdistelmään.
K: Mistä tiedän, milloin nivelakselini osat on vaihdettava?
A: Yleisiä merkkejä voimanottoakselin osien vaihtotarpeesta ovat: havaittava tärinä käytön aikana (kuluneet voimanottoakselin U-nivelen laakerit), vaikeudet akselin teleskooppiliikkeessä (naarmuuntuneet tai syöpyneet voimanottoakselin putkipinnat), kuuluva naksahdus tai poksahtelu (vialliset poikkilaakerit), näkyvä rasvavuoto laakerikansista (vaurioituneet tiivisteet) ja liiallinen välys tai heiluminen voimanottoakselin haarukkaa tartuttaessa lähellä mitä tahansa niveltä. Jos havaitset jonkin näistä oireista, tarkasta ja vaihda vaurioituneet osat viipymättä, jotta sekoittimen vaihdelaatikko ei vaurioidu ketjureaktion kautta.
K: Tarjoaako CMN Transmission erikseen nivelakselin suojien vaihtoja?
V: Kyllä, voimanottoakselin suojus ja voimanottoakselin suojuksen osat ovat saatavilla erillisinä varaosina. Voimanottoakselin käyttö ilman toimivaa suojusta on erittäin vaarallista ja rikkoo turvallisuusmääräyksiä useimmissa lainkäyttöalueissa. Jos nykyinen suojuksesi on haljennut, puuttuu tai sisäinen laakeri ei enää salli vapaata pyörimistä, CMN Transmission toimittaa vaihtosuojia, jotka on mitoitettu vastaamaan kutakin akseliluokkaa Jaylor TMR -sekoitinsovelluksiin.
K: Mitä sertifikaatteja CMN Transmissionilla on voimanottoakselien valmistukseen?
A: CMN Transmissionilla on ISO9001-laatusertifikaatti, CE-merkintä Euroopan markkinoiden vaatimustenmukaisuudesta ja TS16949-autoteollisuuden laatusertifikaatti. Nämä sertifikaatit varmistavat, että jokainen maatalouden nivelakseli valmistetaan valvotuissa prosesseissa, joissa on dokumentoitu materiaalin jäljitettävyys, mittatarkastusrekisterit ja laadunvalvontamenettelyt raaka-aineesta valmiiseen kokoonpanoon.
K: Voiko tätä nivelakselia käyttää muiden merkkien pystysuuntaisissa rehunsekoittimissa kuin Jaylorissa?
A: Vaikka tämä Jaylor-rehunsekoittimen nivelakseli on erityisesti suunniteltu ja mitoitettu Jaylor 6600-, 6650-, 6750- ja 6850-kaksoisruuvisten TMR-sekoittimien käyttöön, sen alla olevat nivelakselin osat ja voimansiirtoarkkitehtuuri ovat yhteensopivia muiden pystysuuntaisten rehunsekoittimien nivelakselisovellusten kanssa, joissa käytetään samoja uraprofiileja, akseliluokkaa ja 1000 rpm:n käyttönopeutta. CMN Transmission valmistaa myös erillisiä nivelakseleita muille rehunsekoitinmerkeille, kuten Supreme, Peecon, Kuhn Knight, NDE ja Penta. Ota yhteyttä suunnittelutiimiimme ja kerro sekoittimesi malli ja traktorisi tekniset tiedot yhteensopivuusarvioinnin saamiseksi.

Asiakasarvostelut
Robert Vandenberg, maitotilan omistaja, Yhdysvallat
"Meillä on 600-pään maitotila Wisconsinissa, ja Jaylor 6750 -traktoriamme käytetään kahdesti päivässä, 365 päivää vuodessa. Neljän kauden jälkeen alkuperäiset Bondiolin ristinivelet paloiteltiin kokonaan ja putkiprofiili uritettiin. Tilasin CAT6-vaihtoliittimen CMN Transmissionilta, ja se saapui 12 päivässä ovellemme. 1-3/8 tuuman 21-urainen liitos meni suoraan traktorimme 1000 rpm:n voimanottoakselin päähän ilman muutoksia. Olemme nyt käyttäneet uutta akselia noin 300 tuntia sekoittaen maissisiilon, heinäsäilörehun ja viljatiivisteiden kanssa, ja se käy yhtä tasaisesti kuin asennuspäivänä. Liukukytkin pelasti meidät jo kerran, kun jäätynyt säilörehun pala osui ruuvien väliin. Olen erittäin tyytyväinen rahoilleni."
Craig Morrison, ruokintapaikan johtaja, Kanada
"Johdan Albertassa naudanlihanruokintatilaa, jossa on kaksi Jaylor 6850 -sekoitinta. Kun toinen nivelakselimme alkoi pitää ääntä ristinivelissä, otin yhteyttä CMN:ään löydettyäni heidät verkosta. Heidän tiiminsä oli nopea ja auttoi minua valitsemaan oikean kytkimen vääntömomentin toimintoomme. Akselin laatu on erittäin hyvä, haarukan työstö tuntuu tiukalta ja tarkalta. Toimitus Kanadaan kesti noin kaksi ja puoli viikkoa, mikä oli nopeampaa kuin odotin ulkomaiselta toimittajalta. Olemme käyttäneet akselia nyt viisi kuukautta päivittäisessä käytössä, eikä mitään ongelmia ole ollut. Suojamuovi on paksumpaa kuin alkuperäinen ja rasvanipat ovat helposti saavutettavissa."
Klaus Richter, maatilan toiminnan johtaja, Saksa
"Käytössämme on 420 putken nivelakseli ja sen käyttöön tulee Jaylor 6650 -kierreakseli. Vanha nivelakseli oli Walterscheid-tyyppinen ja kesti noin 3 vuotta ennen kuin putket alkoivat jumiutua. CMN:n vaihtoakseli liukuu erittäin sujuvasti ja poikkilaakerit tuntuvat paljon tukevammilta kuin aiemmat akselimme. Hinta oli noin 40% vähemmän kuin mitä paikallinen jälleenmyyjämme tarjosi Bondiolin alkuperäisestä akselista. Toimitus Saksaan kesti 18 päivää, mikä oli hyväksyttävää. Mekaanikkoni sanoi, että uran ja haarukan mittatarkkuus on erinomainen. Sekoitamme noin neljä erää päivässä, ja tämä akseli selviytyy työmäärästä valittamatta."
Shane Rutherford, karjankasvattaja, Australia
"Lammas- ja vuohitilallamme New South Walesissa käytetään Jaylor 6600 -sekoitinta noin 1 200 eläimen rehun sekoittamiseen. Vanhat nivelakselin murtopultit katkesivat joka toinen viikko, mikä maksoi meille aikaa ja tuotantoa. CMN suositteli päivittämistä omaan liukukytkimeensä. Paras päätöksemme. Kytkin käsittelee kuivien heinäpaalien kuormituspiikit ongelmitta, eikä meillä ole ollut yhtäkään suunnittelematonta seisokkia neljän kuukauden päivittäisen käytön aikana. Asiakaspalvelutiimi lähetti minulle myös yksityiskohtaisen mittapiirroksen ennen tilausta, jotta voisin varmistaa, että pituus vastaa traktorimme asetuksia."
Alejandro Navarro, meijerialan toimija, Argentiina
"Ostan CMN:n voimanottoakselin Jaylor 6750 -akselillemme. Olin skeptinen ostaessani ei-eurooppalaiselta merkiltä, mutta laatu ylitti odotukseni. Seosteräksestä valmistetut haarukat ovat painavat ja hyvin koneistetut, murrosnivelissä ei ole välystä heti pakkauksesta otettaessa, ja turvasuojus on suunniteltu oikein, ja ketjun kiinnityspisteet ovat molemmissa päissä. Meillä on 350 lehmän maitotila lähellä Córdobaa, ja akseli on toiminut moitteettomasti kuuden kuukauden raskaan talviruokinnan ajan. Mekaanikkomme huomasi, että poikkilaakerien rasvanipat ovat 90 asteen kulmassa toisiinsa nähden eivätkä kaikki ole samalla puolella, mikä helpottaa voitelua paljon ahtaissa tiloissa."
Wei Jianping, maatilan tekninen johtaja, Kiina
"Meillä on 8 000 eläimen kaupallinen sikatila Henanin maakunnassa ja käytämme Jaylor 6650 -konetta kylvö- ja karjarehun sekoittamiseen. CMN Transmission on kotimainen toimittajamme, joten toimitus kesti vain viisi päivää. Voimanottoakseli saapui hyvin pakattuna, urien suojakorkit ja ristinivelet esivoideltuina. Asennus kesti noin 30 minuuttia. Akseli käsittelee käyttämämme kosteat maissi- ja soijapapujauhoseokset ilman tärinäongelmia. Eniten minuun teki vaikutuksen tekninen tuki. Heidän insinöörinsä soitti meille varmistaakseen traktorimme voimanoton tekniset tiedot ennen toimitusta, mikä esti mahdollisen urien yhteensopimattomuuden vanhemman traktorimallimme kanssa."
Jean-Pierre Delacroix, hevostilojen johtaja, Ranska
"Ostin CMN:ltä kaksi nivelakselia Jaylor 6600- ja 6850-sekoittimiimme hevoskasvatuslaitoksellamme Deauvillen lähellä. Hevoset tarvitsevat erittäin tasalaatuista rehuseosta, ja kaikki ruokinta-aikataulun keskeytykset aiheuttavat stressiä tallissa. Nämä akselit ovat toimineet nyt kahdeksan kuukautta, ei melua, ei tärinää, ei kytkimen luistamista normaalikuormituksessa. 1000 rpm:n kierrosluku on tasainen ja turvasuojukset pysyvät täysin paikallaan, kun akseli pyörii alla. Arvostan myös sitä, että CMN toimitti lähetyksen mukana metriset mittatodistukset, jotka vakuutustarkastajamme vaati maatalouskoneidemme vaatimustenmukaisuustiedostoa varten."
Ricardo Ferreira, operaatiojohtaja, Brasilia
"Toimitamme TMR-seosrehua kolmelle meijeriosuuskunnalle São Paulon osavaltiossa. Käytämme Jaylor 6750- ja 6850 -sekoittimia yhteensä 12–14 erää päivässä koko kalustoomme. Voimanottoakselin luotettavuus ei ole meille valinnainen asia, vaan se ratkaisee, noudatammeko toimitussopimuksia tai maksammeko sakkoja. Vaihdoimme CMN-akseleihin 10 kuukautta sitten, kun Bondiolin varaosien toimittaminen paikallisen jälleenmyyjämme kautta viivästyi toistuvasti. CMN-akselit ovat toimineet identtisesti alkuperäisten kanssa, mutta huomattavasti halvemmalla. Tehdas toimittaa ne suoraan meille, ja akselit saapuvat kiinteissä puulaatikoissa asennusvalmiina."
Murray Henderson, maidontuottaja, Uusi-Seelanti
"Lypsytilamme lähellä Christchurchia on käyttänyt CMN:n nivelakselia Jaylor 6650 -sekoittimessamme jo yli vuoden ajan. Lypsämme 480 lehmää ja sekoitamme kolme erää päivittäin huippusesongin aikana. Akseli on toiminut reilusti yli 500 tuntia, ja sitä on voiteltu vain kahdeksan tunnin välein. Minulla oli hieman epäilyksiä ulkomailta tilaamisesta, mutta CMN:n myyntitiimi tarjosi WhatsApp-tukea koko tilaus- ja toimitusprosessin ajan, mukaan lukien kuvia omasta akselistamme ennen kuin se lähti tehtaalta. Liukukytkinmekanismi tuntuu vakaalta ja vääntömomentti on pysynyt tasaisena. Kun toinen sekoittimemme tarvitsee akselin vaihdon, tilaamme uudelleen CMN:ltä ilman, että vertailemme eri vaihtoehtoja."
