Appreciate the responses.  I'm sure MacLorry is right on target and once the weather warms up I'll start in and see what's not connected.  I just tried to see if my machine could 'heal itself' and when that didn't work I looked at the Right wheel and saw that the cotter pin was missing, causing the wheel to move on the shaft.  Thinking that was my only problem I replaced the pin temporarily with a screw and nut.  Still though not getting any 'drive' action but possibly with the missing pin the axle has moved out of alignment ???  So once I get the covers off maybe the problem will be easy to see.  Happy New Year !!!! 

My 3 year old machine just developed this same problem.  It worked fine in the last snowstorm of 14".  Tried it last night and it wouldn't propel.  Luckily it was only a 4" storm and I was able to 'self'-propel it and cleared most of the driveway.  I looked at the linkages and I don't see an obvious problem.  This model doesn't use shearpins and the chain belt looks to be intact.  Any thoughts?
