Kawasaki Mule 610 shutter

[golfgooroo]

Would anybody be able to help me figure what I did to our mule. I would using it to winch out a stuck tractor and with it in 4x4 and locked differential, my son was giving it gas but it wasn't able to pull the small tractor out because it was REALLY stuck. So heavy throttle for 30 sec or so with no tire movement. No worries, I got the tractor out with the truck but now the Mule has a shutter when in gear at a standstill. The shaking goes away in neutral and is less prounounced with brake applied. Hoping it's something i can adjust or replace.

Thanks for the help!

My first guess would be to look at the drive belt. Pulling like that may have worn the sides real bad in one or tow areas and now you would get a shudder effect each time the worn section went over the pulleys.

My thought too....may have smoked the CVT belt.
