On my 400 I extended the bracket for the front(I think) idler so it sits much taller. I think I did it to accommodate a longer belt when I didn't have the right one, but has never twisted since then, and gives more wrap around the small pulley for less slippage. I just used a piece of flat bar, bolted an idler to one end and bolted it into the slot on the bottom. Might be shimmed or tipped to keep everything in line.
I do know that they were never built to spin a large diameter pickup reel in a wet down tangled crop. I carry all spare belts, roll pins, even pulleys and chains.
I also know that if I never see another twisted belt again it will be too soon.
Swather is unofficially retired now, at least that is the plan, doesn't break my heart at all.
Also check if any of the pulleys are bent or warped, the big one could easily be damaged by forcing a belt into it without unbolting the bearing, since it sits too close to the frame otherwise.
