Folks--
Need a little help here. Have a '76 c120 automatic. Starts right up and engine runs great. Moved fine in fwd and reverse at the beginning of the snow season, but past two times I've plowed with it the transmission (or something) has quit on me in the middle of a plow. Usually first happens when I'm stopping to put it into reverse. Might catch a little, but then stops. No noises, nothing else noticeable. If I had to find something to comment on, it would be that the lever to engage the transmission feels like it has less resistance than normal. In the past, I've let it sit for a little and then it's worked. Other times it will start working, then I'll shut it off a minute later and when I restart--nothing. Last night I went to turn it around in the garage and got halfway through a 3 point turn before she just stopped moving. Again--no noise and no engine problems.
One other point--when this happens the tractor can be pushed without having to unlock the push valve. But I've never tried pushing it that way--just noticed that I could. Valve opens and closes fine, but at this point there isnt any noticeable difference when it's open versus when it's close. It's that last point that worries me.
Whaddya think?
Chris
