My Big Boss shifts so hard I have to turn it off some times to shift it. About a month ago the belt blew on it when the grandson was on a ride and he put a new one on. Now I'm told if any of the belt material got behind the secondary clutch that will mess with the shifting. I will look into it and would appreciate any ones thoughts on it.

Check your fluids in tranny and your shift arms I lubed mine where the accuator connects to shift rods and that helped. PM me for details.
