Question:
Drive belt jumping off of pulleys.
Model=RZ4623,ID=966764501

I am having trouble with the drive belt jumping off the pulleys, even at slow speeds while turning. I bought the RZ4623 from a local Lowes and they know nothing about the mower. They didn't even have it set up correctly when they delivered it. I had to connect the seat interlock safety switch and go back to them for bolts to connect the seat to the mower deck. I'm an automotive engineer so I can follow instructions pretty well if you can deal with me directly. It seems the spring applying force to the idler pulley is too weak to keep the belt from developing a wave large enough to jump the lip of the pulley when I try to turn. It only jumps every other week or so, but the mower only has 9 hours on it.
