I'm trying to change the v belt on my green craftsman riding lawn mower. I need to know how to put it on. What is the path of the belt and what is the procedure in putting it on?

This thread will show you my stock answer for deck belts on all tractors. However you have a drive belt to the trans mission and another belt going to the deck. Which belt is your issue? https://www.askmehelpdesk.com/tools-power-equipment/mtd-riding-lawnmowere-belt-diagram-137312.html or try this one https://www.askmehelpdesk.com/tools-power-equipment/deck-belt-252705.html

I am attempting to replace the mower deck belt. This is on a craftsman model 917.256550.

Review both of my posts and you should be good to go. Bob
