Good To Know

Q: Does this pulley require a special belt? A: Use the belt specified for your tractor model; a worn belt can mimic pulley failure, so inspect both before replacement.

Q: Is professional installation recommended? A: The pulley can be replaced with basic hand tools, but referencing your tractor’s service manual ensures proper alignment and torque.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
