Ok, so my little brothers sled has an issue. Its an '01 Mountain Cat EFI 600 w/136. I haven't experienced it but evidently under full load like in a climb in deep snow, the whole sled will "have a big shudder." I guess the whole sled is shuddering 
. He says when he lets out it will smooth out and quit, then he can hammer it again and be good.
My only thought is belt slippage? If it is slipping how do you fix it?
Any thoughts?
Thanks in advance!
