How do you change the belt that drives the thing?

There are several belts but just one that drives the transmission. Lower the mower deck all the way. Reach between the mower deck and the underside of the tractor. Follow the belt that goes from the engine to the trans, have someone depress the clutch/brake pedal while you find the spring loaded tensioner pulley, pull out on that pulley and you should be able to peel off the belt. It is usually easier to peel it off the trans rather than the smaller pulley on the engine. Good luck and write back if you hit a road block.

More then likely your going to have 2 go under neath it and you'll find two belts, one of them powers the blades the other moves it. Your going to have to find the right size belt and above the axle (between the two back tires) there is a circle disks that the belt fits on, put the belt around that then run to the front where there will be a smaller disk, At least that's how I fixed my sister's,, oh yeah it will help if its in neutral
