What size drive belt do I need for my Snapper zero-turn mower?
This depends entirely on your specific Snapper zero-turn mower model. The model number, usually found on a sticker on the mower deck or frame, is essential to determining the correct belt size. Never guess; consult your owner's manual or the Snapper parts website.
Tools and Materials You'll Need
Before starting the replacement, gather the necessary tools and materials:
