PTO Shaft for Supreme Vertical Feed Mixer Model: 700T, 800T, 900T, 1000T, 1200T, 1400T

The CMN Transmission PTO Shaft for Supreme Vertical Feed Mixers is a purpose engineered tractor PTO shaft designed specifically for the Supreme International TMR lineup spanning the 700T, 800T, 900T, 1000T, 1200T, and 1400T models. As a heavy duty PTO shaft built for continuous load mixing, this PTO drive shaft for feed mixer transmits up to 150 HP at 540 RPM and 120 HP at 1000 RPM, enabling tractors from 90 HP to 220 HP to drive the feed mixer gearbox of Supreme vertical feed mixers with consistent, vibration free torque. The cold drawn lemon profile PTO shaft tubing, induction hardened PTO shaft yoke, and precision ground cross kit combine to deliver service life that typically exceeds 3,500 operating hours when properly maintained.

In real world applications, this vertical feed mixer PTO shaft powers the screw auger of Supreme TMR mixers as they blend silage, hay, grain, minerals, and protein supplements into a homogeneous ration on dairy, beef, sheep, goat, horse, and swine operations. Whether you are running a 700T single auger mixer behind a 90 HP utility tractor on a small dairy, or a 1400T twin auger unit pulled by a 220 HP row crop tractor on a commercial feedlot, this PTO shaft for Supreme TMR mixers integrates a slip clutch PTO shaft or shear bolt PTO shaft protection system, safety telescoping PTO shaft guard, and SAE standard splines that match Supreme OEM dimensions. It functions equally well as a factory fit replacement or as a direct replacement of Weasler PTO shaft units already in the field.

Features of PTO Shaft for Supreme Feed Mixer

1. Precision Forged Yoke & Cross Kit
Each PTO shaft yoke is closed die forged from 40Cr alloy steel and induction hardened to HRC 52-56, delivering yield strength above 850 MPa. The matched PTO shaft u joint cross kit uses needle bearings with sealed end caps, lubricated for life with lithium complex grease. This combination withstands the shock loads generated when a loaded Supreme 1400T auger meets frozen silage or baled hay cores, giving the PTO driveline shaft a service life that typically exceeds 3,500 operating hours.

2. Heavy Duty Slip Clutch Protection
A factory calibrated friction slip clutch PTO shaft protects both your tractor and the Supreme mixer gearbox from sudden overload. Torque release is factory set between 1,800 Nm and 2,400 Nm depending on mixer size, and the friction discs can be re-faced in the field. Customers can also specify a shear bolt PTO shaft or ratchet type PTO shaft with slip clutch for redundant overload safety, reducing expensive gearbox repairs on 1000T and 1200T vertical mixers.

3. CE Certified Safety Guard
The full length PTO shaft guard is injection molded from high impact polyethylene that remains flexible down to minus 30°C, critical for winter feeding in Canada, Russia, and Nordic dairies. The two piece rotating PTO shaft cover meets EN 12965 and CE safety standards, with a restraint chain anchor and grease access port on every bearing. This PTO shaft parts assembly keeps livestock workers safe while preserving the bearings inside.

4. Cold Drawn Telescoping Tube Profile
The inner and outer PTO shaft tube are cold drawn from C45 carbon steel in a lemon, triangular, or star cross section. The 4.5 mm to 5.0 mm wall thickness prevents tube collapse under the off angle shock loads common when a Supreme 900T mixer pivots over uneven yard concrete. Surfaces are phosphate coated for low friction sliding, and PTO shaft dimensions are matched within 0.1 mm tolerance to avoid rattle at 1000 rpm PTO shaft speed.

5. OEM & Custom PTO Shaft Fit
CMN Transmission offers a full range of custom PTO shaft configurations: 1 3/8" 6-spline, 1 3/8" 21-spline, 1 3/4" 20-spline tractor ends, plus optional quick release push pin, ball detent, or collar locks. PTO shaft sizes cover series 4 through series 9 to match every Supreme model from the compact 700T up to the 1400T twin auger. Any PTO shaft length from 800 mm to 2,100 mm closed can be specified without tooling charge for orders above five pieces.

6. Direct Replacement of Weasler PTO Shaft
Dimensionally engineered as a drop in replacement of Weasler PTO shaft and Walterscheid units, this aci PTO pertanian uses interchangeable yokes, cross kits, and tubing so field crews can swap damaged parts from their existing PTO shaft parts inventory. No tractor modification is needed and no PTO shaft adapter is required for standard Supreme 700T-1400T installations, saving up to four hours of downtime during peak silage season.

Working Principle of Feed Mixer PTO Drive Shaft

The PTO Shaft for Supreme Vertical Feed Mixers operates as the mechanical power bridge between the tractor Power Take Off stub and the input gearbox of the mixer. When the tractor operator engages the PTO lever, the 540 PTO shaft or 1000 PTO shaft output of the tractor transmission begins rotating at a fixed ratio relative to engine RPM. This rotation is transmitted into the tractor end yoke of the PTO drive shaft through the internal splines, which mesh with the tractor PTO stub. The torque then flows through the first PTO shaft universal joint, which is essentially a hooke type cross and bearing assembly that allows up to 25 degrees of continuous angular misalignment between the tractor and the mixer drawbar hitch.

From the first u joint, torque travels into the inner telescoping tube. The telescoping feature is critical because the distance between the tractor PTO stub and the mixer gearbox changes constantly as the mixer is pulled over uneven ground, turned in tight farmyards, or loaded with feed. The lemon, triangular, or star profile tubes slide axially within one another while still transmitting full rotational torque, preventing any backlash or spline wear that would be seen on a splined sleeve design. The cold drawn surface and molybdenum disulfide coating inside the tube keep sliding friction below 0.12, so no binding occurs even when the Supreme 1200T is fully loaded with 12 cubic meters of wet silage.

Torque exits the telescoping tubes through the second PTO shaft u joint, then enters the protection device. On most Supreme feed mixer PTO shaft configurations this is a friction slip clutch PTO shaft that holds factory calibrated friction discs under Belleville spring pressure. As long as the torque remains below the slip threshold, the clutch acts as a rigid link. If the auger suddenly jams against a frozen silage face or a foreign object, the friction discs slip and limit the torque peak to a safe value, protecting the Supreme feed mixer gearbox, the mixer auger, and the tractor transmission. A shear bolt PTO shaft variant can replace this function using a calibrated shear pin PTO shaft that breaks cleanly above the rated torque.

After the safety device, the torque is delivered into the mixer end yoke, which connects directly to the input shaft of the Supreme vertical feed mixer gearbox. This gearbox then drives the vertical screw auger that performs the mixing, cutting, and discharging functions. Throughout the entire torque path, the rotating inner components are fully enclosed by the two piece PTO shaft cover, which rotates independently on sealed bearings and is held stationary by the restraint chains. This guard prevents loose clothing, livestock, or tools from contacting the rotating shaft while allowing continuous service at 540 or 1000 RPM for eight to ten hour feeding shifts typical of commercial dairies and feedlots.

Kawasan Aplikasi

1. Ladang Tenusu
On modern dairy farms running 150 to 2,000 milking cows, the PTO shaft for TMR feed mixer runs four to six times every day to blend corn silage, haylage, cottonseed, soybean meal, minerals, and buffer into a consistent total mixed ration. The Supreme 700T through 1200T vertical mixers are the backbone of North American, European, and Australian dairy feeding programs. The CMN tractor PTO shaft withstands the long duty cycle of 30 to 60 minutes per mix with fully loaded augers cutting through long fiber hay bales, something a standard duty 540 PTO shaft simply cannot sustain.

2. Operasi Lembu Pedaging
Beef feedlots and cow calf operations rely on the Supreme 1000T, 1200T, and 1400T vertical mixers to prepare finishing rations based on rolled corn, distillers grains, roughage, and protein pellets. These larger TMR units demand a heavy duty PTO shaft that can deliver 140 HP continuously on hot summer days and still start reliably at minus 25°C in winter on the northern Plains and Canadian prairies. The CMN PTO drive shaft's sealed u joints and cold resistant guard make it the preferred replacement of Weasler PTO shaft units on cow calf ranches in Texas, Alberta, and Queensland.

3. Perusahaan Biri-biri & Kambing
Sheep and dairy goat operations increasingly use Supreme 700T and 800T compact vertical feed mixers to deliver precisely formulated rations that improve milk yield and lamb growth. The smaller capacity means mixers are run more frequently, often eight to ten times per day in high density milking parlors. Our agricultural PTO shaft's rapid push pin lock makes hitching to a 90 HP utility tractor a 15 second job, and the slip clutch PTO shaft prevents gearbox damage when wool contaminated hay causes momentary binding in the vertical auger.

4. Operasi Babi (Khinzir)
Farrow to finish swine operations that raise their own pigs on site use the Supreme 900T and 1000T TMR mixers to blend ground corn, soybean meal, whey permeate, lysine, and vitamin premix into consistent rations for gestation, lactation, and grow finish barns. The tractor PTO drive shaft operates under high RPM but lighter torque conditions, making the 1000 rpm PTO shaft configuration ideal. Precision balanced yokes and tight tolerance tubing eliminate the vibration that previously caused premature failure of u joints on low quality aftermarket PTO drive shafts.

5. Operasi Kuda & Ekuin
Racing stables, equestrian breeding centers, and boarding facilities use the Supreme 700T and 800T vertical mixers to prepare custom equine rations that blend chopped alfalfa, oats, beet pulp, and rice bran without damaging fragile hay stem structure. Because horses are sensitive to feed dust and contamination, owners demand a smooth running PTO shaft that does not throw grease onto the mixer sides. Our sealed PTO shaft u joint and factory lubricated cross kits deliver the clean, quiet operation that premium equestrian operations in Kentucky, Newmarket, and Chantilly require.

How to Install PTO Shaft on Supreme Feed Mixer

Step 1: Safety preparation.
Before installing the PTO shaft for Supreme feed mixer, park the tractor on level ground, engage the parking brake, fully disengage the PTO lever, shut off the engine, remove the ignition key, and wait for all rotating parts to stop. Chock the mixer wheels. Wear cut resistant gloves and safety glasses. Inspect the tractor PTO stub, the mixer input shaft, and both yokes of the new PTO driveline shaft for burrs, rust, or damaged splines. Clean all splines with a wire brush and a clean rag.

Step 2: Measure and verify PTO shaft length.
With the tractor correctly hitched to the Supreme 700T-1400T drawbar, measure the distance between the tractor PTO stub groove and the mixer input shaft groove. Compare this dimension to the closed length marked on the shaft label. The telescoping section must retain at least 100 mm of overlap at the longest working position and at least 50 mm of clearance at the shortest position. If the measurement falls outside the allowable range, select a different PTO shaft length rather than forcing the shaft to bottom out, which would destroy the gearbox or the tractor transmission.

Step 3: Grease all fittings.
Locate the grease nipples on both U joints, both telescoping halves, and the guard bearings. Apply 3 to 5 pumps of NLGI 2 lithium complex grease at each point until fresh grease emerges. This pre-lubrication is essential because the factory grease can dry out during shipping and storage. Work the joints through their full angular range while greasing.

Step 4: Connect the tractor end.
Identify the tractor end yoke, which is usually marked with a tractor symbol and carries the slip clutch or shear bolt PTO shaft device on Supreme mixer applications. Pull back the push pin collar or depress the quick-release button, slide the yoke fully onto the tractor PTO stub until the locking balls seat in the groove, then release the collar. Tug the shaft firmly to confirm positive engagement. Do not use a hammer or pry bar, which would damage the internal locking mechanism.

Step 5: Connect the mixer end.
Repeat the quick-release procedure on the input shaft of the Supreme vertical feed mixer gearbox. Verify that the slip clutch or shear bolt end is on the tractor side, not the mixer side, to maximize protection of the more expensive gearbox. Attach both restraint chains: one to the tractor drawbar support and one to the mixer drawbar bracket, using the shortest path that still allows full articulation. The chains must not twist during operation.

Step 6: Function test.
Start the tractor, engage the PTO at low idle, and run the empty mixer for 60 seconds while listening for knocking, rubbing, or vibration. Then stop, inspect for heat at the U joints, and verify that the guard rotates freely relative to the shaft. Bring the engine up to 540 or 1000 RPM PTO speed and run for another two minutes. Only after this clean run is complete should you load the mixer and begin feeding. Document the installation date for warranty tracking.

Cara Memilih Aci PTO Traktor yang Tepat untuk Pengadun Suapan

1. Match PTO Shaft Size to Tractor Horsepower
The number one selection criterion is matching the PTO shaft sizes and series to your tractor horsepower. Supreme 700T and 800T typically pair with tractors from 90 to 130 HP, which call for a series 6 or 7 shaft. Supreme 900T-1200T mixers demand 130 to 180 HP tractors and require a series 8 PTO driveline shaft. The Supreme 1400T twin auger mixer needs 180 to 220 HP and a series 9 heavy-duty PTO shaft. Under sizing causes early failure, and oversizing wastes money.

2. Verify Spline Configuration on Both Ends
Inspect the tractor PTO stub to determine whether you need a 1 3/8" 6-spline or a 1 3/4" 20-spline tractor end, and confirm whether the tractor operates at 540 or 1000 PTO shaft speed. The Supreme mixer input is almost always 1 3/4" 20-spline, but always verify before ordering. A PTO shaft adapter should be avoided when possible because it adds length and reduces torque capacity. Email us a photo of both shaft ends and we will confirm the correct PTO shaft part number.

3. Measure the Installed PTO Shaft Length
With the mixer hitched to the tractor in the operating position, measure the straight line distance between the PTO stub groove and the mixer input groove. Typical closed lengths for Supreme mixer PTO shafts range from 1010 mm for the 700T to 1410 mm for the 1400T with long drawbar. Choose a shaft whose closed length is at least 50 mm shorter than your installed distance. The PTO shaft dimensions must always allow telescoping room on turns.

4. Pilih Perlindungan Beban Lebih yang Tepat
A slip clutch PTO shaft is preferred for operators who mix frozen silage, long fiber hay, or high moisture rations where frequent minor overloads occur, because the friction clutch resets itself after slipping. A shear bolt PTO shaft is preferred for uniform, predictable ratios where overloads would indicate a serious problem. Ratchet-type PTO shaft with slip clutch combinations offer the highest protection for 1200T-1400T mixers, but cost more. Match the safety device to your specific feeding practice.

5. Confirm Certificates and Safety Compliance
European and Australian regulations require CE marked PTO shaft guard assemblies that meet EN 12965 and ISO 5674. North American OSHA rules require ASABE-compliant safety shields. Always choose a PTO shaft cover from an ISO9001 and CE certified manufacturer to avoid fines, insurance issues, and liability after farm accidents. CMN Transmission supplies all required documentation with every shipment, which also helps customs clearance in Europe, South America, and Oceania.

6. Consider OEM vs Direct Replacement
If your Supreme mixer still carries the original Weasler or Walterscheid driveline, a direct replacement of Weasler PTO shaft from CMN will plug in with zero modification. If you want to upgrade to a heavier-duty shaft or to standardize a single PTO shaft part number across multiple mixers, our custom PTO shaft program builds to your drawing in two to three weeks. Ask us about volume discounts on fleet standardization orders.

Penyelesaian Masalah Biasa

1. Knocking or clunking at PTO engagement.
This usually indicates worn U-joint bearings, a loose yoke bolt, or a spline engagement problem. Shut down the tractor, disconnect the shaft, and manually rotate each U joint. Any detectable radial play exceeding 0.2 mm means the cross kit needs replacement. Inspect the yoke ear bores for elongation. If the yoke is oval, replace the entire PTO shaft yoke assembly because a worn bore cannot be salvaged. Check that the push pin collar has fully engaged on both ends.

2. Excessive vibration at 540 or 1000 RPM.
Vibration above 3 mm/s RMS points to a bent tube, an out of balance universal joint, or excessive operating angle. Measure the angle between the tractor PTO and the mixer input with an angle gauge. Both u joints must see the same angle or the driveline will whip. Adjust tractor drawbar position or mixer hitch height until the angles match within 3 degrees. If the tube itself is bent, replace the shaft because straightening cold drawn tubing is not reliable.

3. Slip clutch overheats or slips continuously.
A clutch that smokes or slips during normal mixing has either a torque setting that is too low, glazed friction discs from contamination, or a loaded mixer that exceeds the clutch capacity. First, clean the friction discs with brake cleaner and sand them lightly with 120 grit paper. Re adjust the Belleville spring compression per the label torque. If slip persists, reduce the mixer load per batch or upgrade to a higher rated slip clutch PTO shaft. Never tighten the clutch past factory maximum because this defeats the safety function.

4. Shear bolt fails repeatedly.
If the shear pin PTO shaft keeps breaking, do not substitute a higher grade bolt because that will transfer the overload into the gearbox. Instead, investigate the root cause: frozen silage, a foreign object in the auger, binding bearings in the mixer, or a seized auger stub. Check the mixer auger rotation by hand. Examine the previous batch for metal fragments or stones. Use only the exact grade and diameter shear bolt PTO shaft part number specified by CMN for the Supreme model in use.

5. Grease leaking from the guard or the U joint.
Minor grease weeping at the cross seals is normal during the first two hours of operation. Heavy leakage indicates a damaged seal, a ruptured cross, or over-greasing. Wipe clean, then operate for 30 minutes and re-inspect. If fresh grease continues to leak, replace the cross kit. Over-greasing can also push grease past the guard bearings into the PTO shaft cover, creating a slippery hazard at the tractor operator platform.

6. Guard does not rotate freely.
A stationary guard rotating with the shaft is a serious safety issue. The guard bearings may have seized from lack of grease, the restraint chain may be wrapped around the shaft, or ice and feed debris may be jammed between the guard and the tube. Disconnect, clean all debris, regrease the two guard bearings, and verify the restraint chain pulls straight without looping. Replace any PTO shaft guard that has cracks, missing material, or deformed bearing housings. Never operate without a functional guard.

The Feed Mixer PTO Shaft and the Feed Mixer Gearbox are the two mechanical heart components of every Supreme vertical feed mixer. The PTO shaft is the rotating tubular driveline that carries torque from the tractor PTO stub to the input shaft of the mixer, incorporating telescoping tubes, two universal joints, a slip clutch or shear bolt, and a safety guard. It is a power transmission element that must absorb angular misalignment, length variation, and shock loads while transferring 80 to 220 HP at 540 or 1000 RPM.

The feed mixer gearbox, by contrast, is a sealed cast iron or cast steel housing containing helical or spiral bevel gears and heavy taper roller bearings. It sits directly on the mixer tub and drives the vertical screw auger that actually cuts, blends, and discharges the total mixed ration. The gearbox reduces the incoming 540 or 1000 RPM PTO shaft speed to the 28 to 45 RPM required at the auger, multiplying torque by a factor of 12 to 25 times. Supreme vertical mixer gearboxes typically transmit 80 to 200 HP continuously and are engineered to survive the dust, ammonia, and moisture environment of livestock barns.

The connection between the two components is direct and critical. The PTO shaft output yoke bolts directly to the input shaft flange of the gearbox, meaning every torque spike, every vibration, and every misalignment in the PTO shaft is transmitted straight into the gearbox bearings. A failing PTO shaft u joint will quickly damage the gearbox input seal and pinion bearing, causing repair costs ten to twenty times greater than the PTO shaft itself. This is why farmers who standardize on a quality CMN Transmission PTO shaft routinely see their Supreme mixer gearboxes last 8,000 to 12,000 hours instead of the 3,000 to 5,000 hours typical with cheap aftermarket drivelines. CMN also supplies matched feed mixer gearbox units for the 700T through 1400T range, making us a one stop source for the complete driveline system.

Soalan Lazim

Q: Will this PTO shaft fit all Supreme vertical feed mixer models from 700T to 1400T?
A: Yes, our PTO shaft for Supreme TMR mixers is configured to cover the complete 700T, 800T, 900T, 1000T, 1200T, and 1400T model range. The specific series (6 through 9), length, and safety device change with mixer size, so when ordering please specify your exact model, tractor PTO shaft speed (540 or 1000), and tractor horsepower. Our technical team will confirm the correct PTO shaft part number before shipping.

Q: Can this replace a Weasler or Walterscheid PTO shaft?
A: Absolutely. This unit is engineered as a direct replacement of Weasler PTO shaft as well as Walterscheid drivelines on Supreme vertical feed mixers. Spline dimensions, cross journal size, tube profile, and guard mounting are all dimensionally interchangeable. No tractor or mixer modification is required, and no PTO shaft adapter is needed for standard Supreme installations.

Q: What is the difference between a 540 PTO shaft and a 1000 PTO shaft for my Supreme mixer?
A: A 540 PTO shaft rotates at 540 RPM and is standard on tractors below 130 HP, while a 1000 rpm PTO shaft rotates at 1000 RPM and is typical on larger tractors above 130 HP. Supreme mixer gearboxes are designed for a specific input speed, so you must match the PTO shaft speed to both the tractor and the gearbox. Running the wrong speed reduces mixing efficiency and damages the gearbox.

Q: Should I choose a PTO shaft with slip clutch or a shear bolt PTO shaft?
A: The slip clutch PTO shaft is generally preferred for feed mixing because it resets itself automatically after a minor overload, which is valuable during daily ration mixing. A shear bolt PTO shaft requires manual replacement of the shear pin and is better suited to predictable, uniform feeding where any overload indicates a serious issue. CMN also offers a ratchet type PTO shaft with slip clutch for the largest 1400T mixers where redundancy is desired.

Q: What is the lead time for a custom PTO shaft order?
A: Standard PTO shaft part numbers ship from stock in 7 to 15 days. Custom PTO shaft orders with specific length, spline configuration, or safety device calibration typically take 18 to 25 working days from purchase order confirmation. We can expedite urgent orders for an additional fee. Air freight to North America and Europe adds 6 to 10 days, while sea freight takes 22 to 40 days depending on destination port.

Q: What PTO shaft sizes and lengths are available for Supreme mixers?
A: We stock PTO shaft sizes from series 4 (up to 65 HP) through series 9 (up to 220 HP), covering every Supreme vertical feed mixer application. Closed PTO shaft length ranges from 800 mm to 2,100 mm depending on your tractor and mixer hitch geometry. For Supreme 700T-1400T, the typical closed length is 1010 mm to 1410 mm. Always measure your installed distance before ordering.

Q: Do you supply PTO shaft parts separately for field repair?
A: Yes. We carry a full range of PTO shaft parts including yokes, cross and bearing kits, telescoping tube profiles, slip clutch friction discs, shear bolts, safety guards, and grease nipples. Field crews can rebuild damaged PTO drive shafts rather than replacing the entire assembly, saving cost and downtime. Quote requests on individual parts are usually answered within 24 hours by email or WhatsApp.

Q: How do I know the correct PTO shaft length for my Supreme mixer?
A: Hitch your tractor to the Supreme mixer in the operating position and measure the straight line distance between the groove on the tractor PTO stub and the groove on the mixer input shaft. This is your installed distance. The closed PTO shaft length must be 50 to 100 mm shorter, and the extended length must be 50 to 100 mm longer than the range of motion during field use. Email us photos with measurements and we will confirm the correct PTO shaft dimensions.

Q: What certifications does this agricultural PTO shaft carry?
A: Every PTO drive shaft for feed mixer we ship carries CE marking per EN 12965, ISO 9001 quality management certification, and TS 16949 automotive quality standard. The PTO shaft guard meets ISO 5674 safety requirements and North American ASABE standards.

Jeremiah Vanderwall, Dairy Farm Owner, United States
"Running a 1,200 head Holstein operation in Wisconsin, and we mix ration on a Supreme 1200T five times a day. The original Weasler driveline lasted about 4,200 hours before the front u joint started knocking. Ordered the CMN heavy duty PTO shaft as a direct replacement, 1 3/4 20-spline both ends with the friction slip clutch. Install took my hired hand about 20 minutes in the yard. We're 1,300 hours in now and it runs smoother than the original, honestly. Grease zerks line up perfectly, guard spins free, and the clutch hasn't slipped once even when we bury the auger in frozen corn silage. Will buy again for the other two mixers."

Dietrich Braunschweiger, Beef Feedlot Manager, Germany
"We run two Supreme 1400T twin auger mixers on our feedlot near Münster, pulled by Fendt 724 tractors at 1000 PTO RPM. The CMN tractor PTO drive shaft arrived within 11 days from Qingdao to Hamburg, properly crated, zero damage. CE documentation was exactly what the German TÜV inspector wanted, no paperwork hassles. Ran the new shaft through an entire winter feeding season now, about 14 hours daily, and the slip clutch calibration has stayed exactly on target. Price was just over half of what Bondioli quoted me, and the tolerances feel equivalent. Sehr gut, would recommend to any German farmer running Supreme mixers."

Callum Mackintosh, Ranch Owner, Canada
"Up here in Alberta we had minus 38 Celsius for two weeks straight in January and my old Walterscheid shaft on the Supreme 1000T snapped a cross on the first cold morning. Called CMN, they had the heavy duty replacement shipped air freight to Calgary in six days. The plastic guard stayed flexible at those crazy temperatures, no cracking, no brittle breakage like the old one. Splines were tight out of the box, grease was already packed into the u joints. Three winters in and she's still running strong. The service guy was actually responsive on WhatsApp even with the time difference, which honestly shocked me."

Oliver Henderson, Farm Operations, Australia
"We run a 4,000 hectare mixed beef and cropping operation south of Toowoomba in Queensland. Needed a replacement of Weasler PTO shaft for our Supreme 900T and CMN was recommended by a neighbor. Ordered the 540 PTO shaft version with shear bolt protection since we prefer shear bolts in the Aussie dust. Shipping to Brisbane took 22 days via sea, which is normal. Quality is honestly indistinguishable from the OEM unit, weld beads are clean, paint coverage is thick, all welds ground smooth. Cross kits feel heavier actually. Saved us about 1,400 AUD versus the dealer price. No complaints, mate."

Jean-Philippe Lacombe, Dairy Farmer, France
"Dairy farm with 180 Holstein cows in Normandy. Installed the CMN PTO shaft for Supreme TMR mixers on our 800T unit last autumn. The spline match to our John Deere 6155R 1 3/8 21-spline was perfect, which surprised me because previous aftermarket units always had slight play. Eight months of twice daily mixing, zero issues. The friction slip clutch kicked in once when a wooden pallet fragment got into the auger, saved the gearbox completely. CE markings are genuine; I verified with our MSA insurance. Communication in English with the CMN sales team was clear and professional. Very satisfied with this purchase."

Luciano Bertinelli, Gestore Mangimificio, Italy
"We run a 600-head farm in Lombardy using a Supreme 1200T. The PTO shaft for Supreme feed mixer came with exactly the tube profile and length I specified in my drawing, impressive for a custom order. Took about 18 working days from PO to delivery in Verona. Only small complaint is the paint color was slightly more orange than the sample photo, but mechanically perfect. Power transmission at 1000 RPM is vibration free, gearbox temperature at the input seal dropped 4 degrees compared to the old shaft. Good product, reasonable price, would definitely buy a second one when the other mixer needs replacement."

Santiago Echeverría, Ganadero, Argentina
"I have a 450-cow dairy farm near Rafaela, Santa Fe. Ordered a custom PTO shaft for the Supreme 1000T with metric 1 3/4 20-spline tractor end to match our New Holland T7. Delivery to Buenos Aires port took about 35 days including customs clearance, CMN handled all documentation for Mercosur regulations professionally. The heavy duty construction is exactly what we needed because our sorghum silage is very fibrous and the shaft sees heavy intermittent loads. Slip clutch works as advertised. Price was roughly 45 percent of what Bondioli local distributor wanted. Highly recommended for South American farmers running Supreme equipment."

"Our dairy operation in Mazowieckie voivodeship runs a Supreme 700T mixer on a Zetor Proxima 110. Needed an affordable replacement because original unit got damaged when a new employee forgot to disconnect before backing up. CMN's PTO shaft tubing wall thickness is noticeably heavier than the competing brand I considered, probably 5mm vs 4mm. Installed in maybe 30 minutes with basic tools. Running 14 months now at about 1,800 hours, zero grease leakage, no u joint play, the guard still rotates smoothly. Polish documentation was provided for our voivodeship agricultural inspection. Excellent value, very happy, thank you, CMN."

"I own a dairy farm in Minas Gerais with three Supreme mixers: one 900T and two 1200T. I replaced one of the old PTO shafts with the CMN heavy-duty version 22 months ago. The vertical feed mixer PTO shaft performance has been flawless, and the yellow safety guard is still in perfect condition despite exposure to our intense Brazilian sun. The UV resistance is noticeably better than that of a cheaper Chinese brand I tried previously, which cracked within six months. The torque rating matches the original OEM specifications exactly. Customer service responded to my technical questions within hours, in English. I have already ordered the second and third units to standardize my fleet. Thank you very much."
