John Deere tractor gearbox plate

The John Deere tractor gearbox plate is made of alloy steel with tempering and quenching, providing 52–58 HRC surface hardness. Outer diameter ranges from 400 to 480 mm, with 18 mm thickness, supporting gear pressure and torque up to 350 Nm. Mounting holes are machined with ±0.1 mm precision, and dynamic balancing is accurate to 0.02 mm to reduce gearbox vibration.

The contact surface with discs and pads features lubrication grooves that optimize oil flow, reducing friction temperature by 15%. Gearbox plate weight ranges from 15 to 18 kg, with a service life of up to 2,500 hours under standard operating conditions. Anti-corrosion coating and wear-resistant hardening extend durability while maintaining optimized friction coefficient at 0.32.
