Just so we are singing from the same song sheet
You are saying that the drive belt, the top one that connects to the hydros jumps off when you turn the belts on ?

All the belts engage fine but the hydro belt comes off while I'm mowing.

Okay this particular Hustler setup can be cause by several problems. Loose transaxle mounting bolts (screws), Hydro fan blades that have drooped,hitting the drive belt. And single most troublesome part is the little 2 inch idler pulley bearings failing. Being only 2 inches it is operated at overspeed of the bearing rating. Also check the drive belt idler arm for wear.

Referencing Model 938381.

There were some problems with the transaxle cross member support bracket. Take a look for failure there too.

When the 42" Raptor first came out, missing bolts was one of the main problem as Hustler had only used plain nuts. They finally started using nylon lock nuts.

I only worked on one SD so far It had threw the belt but by the time it got here there was a lot more damage so the root cause wasn't discernible. The customer's wife had dropped a tractor bucket on the mower while attempting to loan it. I had to unload and move it around using a floor jack. Wheels would not turn. Several broken bolts was the result so I straighten out the mounts new 8 grade bolts, changed the belt and and idler pulley. I haven't seen it back yet and that was last year. But idler pulley bearing was shot.

Common issue with these mowers. Broken brackets are a big issue. There are updated brackets and cross members for these. However if you have access to a welder and a few pieces of metal you can make it so this never happens again w/o buying any kit from Hustler. One major help is adding a simple cross brace in the rear just over the muffler. Also replace bolts with grade 8.
