AH85276 Tension Wheel JOHN DEERE (Royal Tiger)

Tension Wheel AH85276 for John Deere

The replacement part AH85276 is a tensioning wheel used in the belt drives of John Deere agricultural combines. It maintains the required tension of the drive belt, ensuring smooth torque transfer and stable operation of mechanisms such as straw walkers, lifts, fan drives, and other belt-driven components.

This wheel is made of high-strength steel, equipped with a groove for the belt, and is designed to operate under high loads, dust, and vibrations typical of fieldwork in combines and large equipment.

Application

The AH85276 tension wheel is mounted in the drive system of John Deere grain combines and serves to:

maintain the correct tension of the belt, preventing it from slipping;

reliably transfer torque between the engine, fan, lift, and straw walkers;

reduce vibrations and noise during the operation of the belt drive;

increase belt lifespan and improve the smooth operation of drive mechanisms.

The pulley is an important part of the mechanical drive system of large equipment – timely replacement allows for stable operation of the combine in field conditions.
