PTO Shaft for New Holland Discbines & Disc Mowers

SKU: Multiple Models Available  |  Compatible: New Holland / Case IH Discbines  |  Category: Agricultural PTO Shaft

PTO Shaft-Product Overview

Das Zapfwelle is purpose-engineered as a direct replacement for New Holland Discbine and Case IH disc mower models, covering both Weasler and Bondioli & Pavesi original configurations. Built to handle 65–100 HP inputs at 540 or 1000 RPM, each agricultural PTO shaft is manufactured from high-grade alloy steel and passes CE certification before leaving the factory.

Unlike generic tractor PTO drive shafts, these units are matched to OEM spline counts, yoke dimensions, and CV joint angles for each specific Discbine model — eliminating the guesswork and misfit issues common with universal-fit alternatives. All drivelines incorporate a shear-bolt or friction overload clutch to protect gearboxes from sudden torque spikes during cutting operations.

Compatible models span the full New Holland Discbine range — from the compact 1409/1410 series to the high-output H7560 — as well as Case IH DC 132, giving dealers and fleet operators a single-source solution for multiple machine types.

Rubber Spacer Coupling Performance in Agricultural PTO Drivelines

The rubber spacer coupling integrated into our tractor PTO drive shaft assemblies serves three measurable functions that directly extend drivetrain service life on disc mowers and Discbines:

• Vibration Damping — up to 40% reduction in transmitted vibration: The rubber element absorbs rotational irregularities generated at PTO engagement and during blade contact with dense crop material. This protects the tractor’s transmission and the mower’s gearbox from cumulative fatigue stress.
• Torque Shock Absorption: When a disc mower blade strikes a rock or debris at 1000 RPM, the torque spike can reach 3–5× normal operating load within milliseconds. The rubber coupling deforms elastically under this spike, absorbing the energy before it travels up the driveline to the PTO stub shaft or gearbox input.
• Angular Misalignment Tolerance (±3°): Field terrain is uneven. Rubber spacer couplings tolerate minor angular deviation between the tractor PTO output and the mower input without imposing side loads on the yoke bearings — a common cause of premature cross-bearing failure in rigid drivelines.
• Electrically Isolating: The rubber element provides natural electrical isolation between tractor and implement chassis, preventing stray current corrosion at yoke contact points — particularly relevant in wet or irrigated field conditions.
• No Lubrication Required: Unlike metal coupling spiders, rubber spacer elements require no field lubrication, reducing maintenance intervals. The element is field-replaceable in under 15 minutes without removing the entire shaft assembly.

Benefits of CE Certified PTO Driveline Shafts

Every PTO shaft in this range carries CE certification under EU Machinery Directive 2006/42/EC. For export customers in Europe and buyers sourcing compliant equipment for regulated markets, this means:

• Full safety guard coverage: CE requirements mandate a complete plastic guard tube over all rotating driveline components. Our guard assemblies cover the full shaft length with no exposed section, tested to EN 12965 (PTO drive shafts and their guards).
• Third-party torque rating verification: CE-certified shafts are independently tested to confirm that rated torque capacity matches the marked specification. You receive a shaft that actually handles 55N or 35N — not one that claims it on the label.
• Documented conformity declaration: A Declaration of Conformity is available for every part number, supporting import documentation for EU, UK, and Australian agricultural machinery markets.
• Overload protection compliance: CE certification requires an integrated overload clutch (shear-bolt or friction type) on PTO shafts used in disc mower applications, preventing gearbox damage during sudden blade stalls. All our Discbine-spec shafts include a compliant clutch.

Applications of PTO Shafts in Agricultural Machinery

While this listing is specifically configured as a PTO shaft for disc mowers and Discbines, the same driveline engineering applies across a wide range of tractor-powered implements. As a specialist agricultural PTO shaft manufacturer for discbines and related machinery, we supply compatible shafts for the following applications:

Contact us with your implement model and tractor PTO specification — we can cross-reference the correct shaft, yoke, and clutch combination for applications beyond the Discbine models listed above.

Features of Heavy-Duty PTO Shafts

• Alloy Steel Tube — wall thickness 4–6 mm: Cold-drawn seamless steel tube in the 35N and 55N series meets the torque and bending loads generated by 65–100 HP disc mower operations, with a static torque rating of ≥1,500 N·m on 55N shafts.
• Double CV Joint (80°/50° rated): The double constant-velocity configuration on models like part 14656853 maintains smooth torque delivery even when the mower head swivels or the terrain forces a 50° operating angle — preventing the speed fluctuation that damages gearbox input seals on standard universal joints.
• OEM-Matched Spline Profiles: Tractor yokes are ground to 1.375-21 spline (6-spline) or 1.750-20 (21-spline) profiles matching New Holland CAT 3 and CAT 6 PTO stubs. No adapter required — direct bolt-on fit.
• Overload Clutch — factory set at 1.1× rated torque: Shear-bolt or multi-disc friction clutch disengages when torque exceeds the shaft’s continuous rating, protecting the mower gearbox from sudden stalls. Clutch can be reset in the field without tools in under 5 minutes (friction type) or with a standard bolt (shear type).
• Full-Length Safety Guard with Locking Chain: Co-rotating plastic outer guard covers the entire shaft length. The retaining chain prevents the guard from rotating with the shaft if the outer tube contact is lost — required under EN 12965 and all North American PTO safety standards.
• Surface Treatment — zinc phosphate + topcoat: All metal components receive zinc phosphate pretreatment followed by a 60–80 µm epoxy topcoat, providing 500+ hours of salt spray resistance (per ISO 9227) for operation in irrigated or coastal agricultural environments.
• Operating Temperature Range: −30°C to +80°C: Grease-packed cross bearings and rubber coupling elements are specified for year-round field operation across North American and European climates, from winter soil preparation to summer hay cutting.
