How will installing these pulleys affect deck performance?

Replacing worn pulleys with properly sized, precision-machined parts reduces belt slippage, noise, and uneven blade speed. That helps protect belts and other drive components, giving more consistent cut quality and fewer unscheduled repairs.

• Reduces belt fraying and premature wear
• Improves belt tracking and cuts down on vibration
• Helps maintain consistent blade speed for a more even cut

What should I check during installation to ensure longevity?

Inspect pulleys, mounting bolts, and surrounding deck hardware for wear or damage before installation. Proper torque on the supplied hardware and clean, debris-free spindles will maximize service life.

• Remove grass, grit and rust from mounting points before fitting
• Use supplied bolt, washer and nylon lock nut and torque to manufacturer spec
• Check belt condition and replace if frayed or cracked while you service pulleys
