Small Engines (Lawn Mowers, etc.): Husqvarna drive belt, problem thanks, transaxle

Question
Hello,
I have a husqvarna 42" ride on with a hydro static drive, the old belt(3 years) started jumping off the drive so I replaced the belt and 2 idler pulley's but it still jumps off when i try to reverse any ideas what may be causing this problem.
Thanks
Tony

Answer
Are the transaxle bolts tight.  Since the belt runs the same direction all the time and it does not jump off in forward drive I'd suspect something is loose and pivoting when in reverse.

Make sure all the pulley bolts/fasteners and all other fasteners in the drivetrain are tight.
