Agricultural PTO Driveline for New Holland & Case IH Disc Mowers<\/h2>\n

This PTO shaft assembly is engineered to transfer rotational power from the tractor output to New Holland Discbine and Case IH disc mower gearboxes. Built around the 55N-series constant-velocity (CV) joint platform, the driveline maintains uniform angular velocity at operating angles up to 80 degrees, reducing vibration and extending component life across 540 rpm and 1000 rpm applications.<\/p>\n

Each agricultural PTO driveline in this range is a direct-fit replacement for OEM Weasler and Bondioli & Pavesi units. Telescoping tubing allows length adjustment for different tractor-implement setups, while precision-ground spline profiles (1.375″ x 21 spline, 1.750″ x 20 spline, or 1.5″ x 23 spline) ensure zero-backlash engagement with both tractor and implement ends.<\/p>\n

<\/p>\n

Compatible Disc Mower Models<\/h2>\n

Our PTO shaft fits the following New Holland Discbine and Case IH disc mower models. Each model uses multiple PTO shafts paired with a combination clutch; shaft types and clutch locations vary by model.<\/p>\n

Key Features of This PTO Shaft Assembly<\/h2>\n
\n
\n

55N-Series CV Joint<\/p>\n

The 80-degree and 50-degree constant-velocity joints maintain uniform rotational speed at high operating angles, which is critical for PTO shafts paired with New Holland Discbine 1431 disc mower setups where the hitch geometry creates steep driveline angles during turns.<\/p>\n<\/div>\n

\n

Precision Spline Profiles<\/p>\n

Manufactured with 1.375″ x 21, 1.750″ x 20, and 1.5″ x 23 spline options. CNC-ground tooth profiles provide tight-tolerance engagement (<0.05 mm backlash), reducing shock loads during PTO engagement and extending cross-kit bearing life.<\/p>\n<\/div>\n

\n

Telescoping Length Adjustment<\/p>\n

The inner and outer profile tubes allow length adjustment to suit varying tractor-to-implement distances. Hardened steel tubing with anti-corrosion coating withstands field debris, moisture, and high-load telescoping cycles without scoring.<\/p>\n<\/div>\n

\n

Combination Clutch Protection<\/p>\n

Each driveline assembly is paired with a friction-disc or shear-pin clutch that absorbs torque spikes when cutting discs encounter rocks or dense material, preventing damage to the gearbox and tractor PTO output shaft.<\/p>\n<\/div>\n

\n

65\u2013100 HP Capacity Range<\/p>\n

Rated from 65 HP (H7220\/H7320 at 540 rpm) up to 100 HP (H7460\/H7560 at 1000 rpm), matching the full operating range of mid- to large-frame New Holland disc mower Discbine models.<\/p>\n<\/div>\n

\n

OEM Cross-Compatibility<\/p>\n

Engineered to interchange with Weasler and Bondioli & Pavesi original equipment, including cross kits, bearing caps, and guard assemblies. No modifications required for installation on factory-spec machines.<\/p>\n<\/div>\n<\/div>\n

<\/p>\n

Applications in Agricultural Disc Mower Operations<\/h2>\n
