How to Put a Riding Lawn Mower Belt On: Deck Belt & Drive Belt Step-by-Step Guide
To put a riding lawn mower belt on: disengage the PTO, remove the deck or access panel, note the old belt's routing path (or consult your model's diagram), loop the new belt around the blade spindle pulleys and idler pulley, engage the tensioner, reinstall the deck, then run the mower at low throttle to confirm the belt tracks without slipping or squealing.
