When to Replace

• Significant stretching that prevents the tensioner from maintaining proper belt tautness.
• Hardening or glazing of the belt surface due to excessive heat or age.

Installation Tips

• Disengage the mower deck and remove the ignition key before starting the installation.
• Refer to the owner manual for the specific belt routing diagram to ensure proper threading around pulleys and idlers.
• Release tension on the idler pulley to provide enough slack to slide the old belt off and the new belt on.
• Ensure the belt is properly seated in the V-grooves of all pulleys before reapplying tension.
• Cycle the mower deck engagement manually once installed to verify the belt tracks correctly.
