Is does not steer at all I have put on a new belt need to know how to adjust it
It sounds like you might have something broken in your variator. Here is a
LINK to the definitive read on rebuilding and adjusting the variator by Lyndon.
To help trouble shoot the problem and to help with the
centering procedure put your Snow Master up on jack stands so it is high enough that the tracks can turn freely. Then with the aid of a helper you can inspect the variator's action while it's operating by putting the machine in gear and turning the steering wheel from side to side. You should be able to see the chives opening on one side whist closing on the opposite side.
Hint: I always remove the hood and air cooling horn when I'm working on the variator. Makes it way easier.
Good luck and post your results back here...
