Tom asked me to better identify my snowblower. Model 910926, tractor 910995,serial 045776. I believe this is a 1971 Ariens. When I depress the clutch it compleatly disengages and the unit comes to a compleat stop.  When I release the clutch she's off and running no slippage. That is except in 1st gear (when I can get it in) and then it  just jerks along. When I am able to get it into 1st, usually by shifting from a higher gear back down to 1st, it pulls fine. I can get it into 1st gear ok , no binding or anything like that, it's just that some times she rolls right along but most of the time it jerks along. I can never go from neutral into 1st without it then jerking along. It's like the friction disk is touching , then not touching, then touching etc. although when I do catch 1st it preforms fine. What do you think?  Thanks,   richb
