Tr\u1ee5c PTO cho m\u00e1y b\u0103m c\u1ecf John Deere Model: 115, 120<\/strong><\/p>\n

The PTO Shaft for John Deere Flail Shredders 115 and 120 is engineered to transfer full engine power from your tractor’s power take-off output to the demanding drivetrain of the John Deere 100 Series drawn flail shredder. Manufactured to CAT4 Series 4 driveline standards, this PTO driveline shaft for flail shredder is constructed from cold-drawn alloy steel tubing, precision-forged yokes, and heat-treated universal joints, delivering consistent, vibration-free power at 1000 RPM PTO speeds. An integrated slip clutch provides overload protection, preventing costly gearbox and drivetrain damage when the flail rotor contacts rocks, stumps, or unexpected debris. The shaft meets ISO 9001, CE, and TS16949 quality standards and is offered as an equivalent replacement of Weasler PTO shaft and other OEM units, at significantly lower cost without any compromise in reliability or safety.<\/p>\n

\nThe built-in slip clutch PTO shaft mechanism automatically disengages the drivetrain when shock loads or sudden obstructions exceed the preset torque threshold, protecting your tractor’s PTO gearbox, the flail shredder gearbox, and the entire PTO driveline shaft from catastrophic overload damage. Unlike a shear bolt PTO shaft which requires stopping work and replacing a bolt after each event, the slip clutch re-engages automatically once the obstruction clears, dramatically reducing downtime in the field. Clutch slip torque is factory-set and field-adjustable.<\/p>\n

\nThe entire power transmission chain begins at the tractor’s rear PTO stub shaft. On most utility tractors paired with the John Deere 115 or 120 flail shredder, this is a standard 1-3\/8″ diameter, 21-spline output rotating at 1000 RPM. The tractor’s engine converts fuel energy into rotational torque, and the PTO gearbox inside the tractor routes this rotation rearward to the external PTO stub shaft. The tractor PTO drive shaft yoke at the tractor end of our driveline shaft slides over this stub and locks via a spring-loaded collar pin, securing the connection and ensuring true axial alignment between the shaft centerline and the tractor PTO output axis.<\/p>\n

\nBefore installing the new PTO shaft tractor connection, shut down the tractor engine completely, engage the parking brake, and wait for all rotating components to stop. Verify that the collapsed and extended PTO shaft dimensions match the measured distance between the tractor PTO stub and the shredder gearbox input stub under both minimum and maximum hitch operating geometry. Confirm that both stub shafts are the correct spline size (1-3\/8″ x 21-spline for 1000 RPM) to match the yoke bore on the replacement shaft. Check that the minimum tube overlap at full extension is at least 150 mm to prevent shaft separation during work.<\/p>\n

\nWith the tractor engine off and PTO disengaged, slide the tractor-end PTO shaft yoke onto the tractor’s rear PTO stub shaft, aligning the spline teeth carefully to avoid cross-threading. Push the yoke fully home until the spring-loaded locking collar snaps over the retention groove on the PTO stub. Pull back firmly on the yoke to confirm the collar has fully engaged and the shaft is secured. Note the yoke’s phasing: both yokes on a standard Cardan driveline must be phased in the same plane (both forks parallel) to cancel velocity variation through the universal joints and ensure smooth rotation at the gearbox end.<\/p>\n

\nBefore the first full field operation, verify the slip clutch PTO shaft torque setting by consulting the spring compression adjustment on the clutch body. The factory setting is calibrated for the John Deere 115 \/ 120 gearbox’s rated input torque. Engage the tractor PTO at low engine speed first to confirm the driveline rotates freely without vibration, noise, or guard interference. Gradually increase speed to full 1000 RPM PTO speed and listen for any abnormal sound from the universal joints or telescoping tube. Confirm the shredder engages and operates at the expected performance level before committing to full-load field operation.<\/p>\n

\nCause and Solution: Vibration in a PTO driveline shaft most commonly results from worn or damaged PTO shaft universal joint needle bearings, incorrect yoke phasing, a bent shaft tube, or operating at excessive angular misalignment above the shaft’s rated angle. Check both universal joints for free rotation and play in all directions. Re-inspect yoke phasing to confirm both forks are in the same plane. Measure the operating angle between tractor PTO stub and implement gearbox input to confirm it does not exceed 15 degrees at maximum articulation. Replace any worn cross-and-bearing sets immediately, as a failed universal joint at operating speed can cause severe equipment and personal safety incidents.<\/p>\n

\nCause and Solution: If the slip clutch PTO shaft slips repeatedly under normal operating conditions rather than only during genuine overloads, the friction disc springs may have fatigued, reducing the clutch’s preset engagement torque below the nominal level required to transmit rated power. Alternatively, moisture contamination or grease migration into the friction disc surfaces can cause sustained slip under normal loads. Open the slip clutch assembly, clean all friction disc faces with a dry cloth or brake cleaner, replace fatigued springs with new components, and reset the spring compression to the correct specification. If the problem is a genuine overload, reduce forward travel speed or cutting depth rather than increasing clutch pressure above its designed limit.<\/p>\n

The flail shredder PTO shaft is the mechanical link between the tractor and the flail mower or shredder. It is a telescoping, two-universal-joint driveline assembly that transmits the rotational torque produced at the tractor’s PTO output shaft to the input stub of the flail shredder’s main gearbox. Without a properly sized, correctly installed, and well-maintained PTO driveline shaft for flail shredder, the shredder cannot operate regardless of how powerful the tractor is or how well the shredder’s internal components are maintained.<\/p>\n

The key engineering characteristics of a flail shredder PTO shaft include its driveline series rating (which determines maximum torque capacity), the spline configuration at each end (which must match both the tractor PTO stub and the gearbox input stub), the overall collapsed and extended length, the operating angle range of the universal joints, and the type of overload protection device fitted. For demanding applications like the John Deere 115 and 120 flail shredders, a CAT4 or Series 4 shaft with an integrated slip clutch is the recommended specification, providing both the torque capacity for heavy vegetation shredding and the overload protection to handle the frequent impact loads inherent in flail shredder operation. CMN Transmission’s PTO shaft for John Deere flail shredder is engineered to all of these specifications and is available with custom yoke configurations, tube lengths, and clutch settings for OEM and aftermarket buyers worldwide.<\/p>\n

The flail mower gearbox, also referred to as the flail shredder gearbox or mulcher gearbox, is the mechanical heart of the shredder machine. It receives the longitudinal rotational input delivered by the PTO driveline shaft and transforms it into the transverse, high-speed rotor rotation required to drive the flail knife blades at the effective cutting velocity needed to shred heavy vegetation. In the John Deere 100 Series flail shredders, the gearbox achieves this through a combination of bevel gears (to redirect the axis of rotation by 90 degrees) and spur gear stages (to achieve the correct speed ratio between the 1000 RPM PTO input and the flail rotor’s operating speed).<\/p>\n

\nA: The John Deere 115 and 120 drawn flail shredders use a standard 1-3\/8″ x 21-spline tractor-end connection for 1000 RPM PTO operation. The implement-end yoke also uses a 1-3\/8″ x 6-spline connection to mate with the shredder gearbox input stub. CMN Transmission’s CAT4 \/ Series 4 PTO shaft for John Deere flail shredder is supplied with these exact spline specifications as standard, with a 1-3\/8″ x 21-spline 1000 RPM version available on request for tractors equipped with 1000 RPM PTO outputs.<\/p>\n

\nA: Yes. CMN Transmission’s PTO driveline shaft for the John Deere 115 and 120 flail shredders is engineered as a dimensional equivalent to the Weasler OEM shaft supplied with these machines. The collapsed and extended lengths, yoke spline sizes, series torque rating, and guard dimensions all match the original Weasler specification, enabling a direct bolt-on replacement of Weasler PTO shaft without modification. Customers consistently confirm that the CMN shaft installs without shimming, adapters, or adjustment to any tractor or implement component.<\/p>\n

\nA: The 540 PTO shaft standard uses a 1-3\/8″ diameter stub with 6 splines and rotates at 540 RPM at rated engine speed. The 1000 PTO shaft or 1000 rpm PTO shaft uses a 1-3\/8″ diameter stub with 21 splines (or a 1-3\/4″ stub with 20 splines for heavy-duty 1000E applications) and rotates at 1000 RPM. For the John Deere 115 and 120 shredders, which are rated for tractors in the 40-75 HP range, the standard 540 RPM configuration is correct. If your tractor only has a 1000 RPM PTO output, please contact CMN Transmission for the appropriate custom PTO shaft configuration.<\/p>\n

\nA: A slip clutch PTO shaft incorporates a friction disc clutch assembly set to disengage automatically when the transmitted torque exceeds a preset limit. This is critically important for flail shredders because the flail rotor frequently strikes rocks, thick stumps, and buried objects during operation, generating instantaneous torque spikes that can be five to ten times the normal operating torque. Without a slip clutch, these spikes propagate through the driveline and can shatter the shredder gearbox internals or damage the tractor’s PTO output gear. Unlike a shear bolt PTO shaft, which requires stopping and replacing a bolt after each overload event, the slip clutch re-engages automatically once the torque returns to normal, dramatically reducing downtime.<\/p>\n

\n“Been running a John Deere 120 on our 120-acre cattle farm in central Texas for the better part of six years now, and we went through two Weasler shafts before I found CMN Transmission online. Ordered the CAT4 unit with slip clutch as a replacement of Weasler PTO shaft and honestly didn’t expect much for the price difference. Thing is, it slid straight onto our 1-3\/8″ x 6-spline stub without any adapter or shimming needed. We’ve had it on the machine for just over a full season now, probably 220 hours, cutting heavy brush and thick Johnson grass along the fence lines. Zero slippage, zero vibration, guard is still solid. Build quality is noticeably better than the last aftermarket unit we tried. Would order again without a second thought.”<\/p>\n

\n“Run a contracting business in Queensland, shredding everything from green cane trash to dried kikuyu pasture on behalf of about eight different farm clients. The conditions here are brutal on equipment, especially on the driveline. I ordered a Series 4 heavy duty PTO shaft from CMN after my original unit on the 115 developed play in both U-joints after about 600 hours. The new shaft arrived in 12 days to Brisbane, which I was happy with. Fit was dead on. I’ve since put over 300 hours on it across five different properties, including some extremely tough cane trash work, and the universal joints are still tight, the tube slides smoothly, and the slip clutch hasn’t given me any trouble. For the price, the quality is really impressive. I’m recommending CMN to a mate who runs a similar setup on a 120.”<\/p>\n

Pierre Lefebvre, N\u00f4ng d\u00e2n, Ph\u00e1p<\/strong>
\n“I use my John Deere 115 to shred crop residues in my cereal fields in the Beauce region. When I needed a new PTO shaft I checked several suppliers but CMN offered the best price without compromising on certifications. The shaft arrived quickly, well packaged, and the PTO shaft dimensions were exactly as specified. I especially appreciated the detailed installation guide included in the box. The slip clutch saved my gearbox twice already during the first season when I hit some buried stones I didn’t know were there. Very happy with the purchase. For the price versus quality ratio, it’s hard to beat for a European farmer watching costs carefully this season.”<\/p>\n

Klaus Weber, Ch\u1ee7 trang tr\u1ea1i, \u0110\u1ee9c<\/strong>
\n“As a farmer in Bavaria with ISO and CE compliance expectations for all equipment I run, I was naturally skeptical about sourcing a PTO shaft for John Deere flail shredder from a Chinese manufacturer. But CMN provided full documentation: ISO 9001 certificate, CE declaration of conformity, and the TS16949 certificate, which no other supplier at this price point could offer. The technical data sheet matched our existing Walterscheid unit in every critical dimension. We installed the shaft on our 120 in April and have been running it through hay and straw work until October without a single issue. The engineering precision is evident when you hold it next to the OEM part. A professional product at a fair international price. We have already ordered two more units for our other machines.”<\/p>\n

\n“I manage a 600-acre estate in Lincolnshire and we use the John Deere 115 shredder extensively for hedgerow base management and grass strip maintenance across the whole property. I was a bit hesitant about the customer service side when ordering from overseas but the CMN team responded to every email within a day and gave me the exact shaft specification I needed including a 1000 PTO shaft version for our 1000 RPM tractor. The shaft itself is well made, heavier than I expected which suggests they haven’t skimped on material, and the guard is decent quality. Delivery to the UK took nine working days which was fine. I’d mark them down slightly only because the tracking information wasn’t updated regularly during transit, but the product is exactly what we needed.”<\/p>\n

\n“I work as an agricultural services contractor in the interior of S\u00e3o Paulo and use the John Deere 120 for shredding sugarcane straw and brachiaria grass. I purchased a CAT4 PTO shaft for the straw shredder from CMN and the cost was very competitive compared to local distributors. The product arrived in 14 days, with excellent packaging and no damage. The fit onto the 6-spline hub was perfect, with no play. I have already operated the shaft for over 400 hours and it is performing very well so far. The overload clutch functioned perfectly on at least ten occasions when the rotor hit stumps on the ground. I am very satisfied with the purchase. I have already recommended it to two colleagues who also work with John Deere shredders in the region.”<\/p>\n

David Kowalski, N\u00f4ng d\u00e2n, Canada<\/strong>
\n“Located in southern Ontario. Ordered a CAT4 tractor PTO drive shaft for my John Deere 115 to replace a shaft that was showing visible wear on the U-joint cups after about four seasons. The CMN unit arrived quickly from their warehouse and the fitment was straightforward. The new shaft installed in under fifteen minutes with basic tools. I greased everything before first use as instructed and have been running it through late-season corn stalk shredding and cover crop mulching without any issue. The slip clutch engagement feels very positive and I’ve confirmed it kicks out properly on a couple of test overloads. Build quality feels solid, heavier steel than some of the budget aftermarket units I’ve seen. Genuinely happy with this purchase and would recommend it to other John Deere 115 \/ 120 operators in Canada.”<\/p>\n

\n“We are an agricultural parts dealership in Emilia-Romagna and have been selling cardan shafts to agricultural professionals for twenty years. I compared the CMN product with Italian and German brand shafts in the same category and can say that the construction quality and dimensional tolerances are absolutely competitive. The universal joints are robust, the tube profiles slide very smoothly, and the slip clutch is well calibrated. The price allows us attractive resale margins without compromising end-customer satisfaction. We have added the models for John Deere 115 and 120 to our official catalog. CMN is a professional supplier that is a pleasure to work with; they respond quickly and the quality documents are always complete and correct.”<\/p>\n

\n“Running a mixed sheep and crop farm in the Waikato and I’ve had the John Deere 115 for about eight years. The original PTO shaft finally gave out a couple of seasons back and I went with a CMN unit on recommendation from a farmer contact in Hawke’s Bay. The shaft has now done two full seasons of fairly intensive work, including some very tough thistle and gorse seedling shredding on paddocks being brought back into production. I grease it every week during peak season and the U-joints and tube are still in excellent condition. The after-sales support from CMN was also impressive when I had a question about the slip clutch adjustment; they responded with a clear technical explanation within 24 hours. For value and durability in the NZ context, I’m very satisfied and would buy from CMN again.”<\/p>","protected":false},"excerpt":{"rendered":"
