My Super C, though, restored is primarily a worker. It started to become a little hard to shift and their was a little more free play than called for. I was able to readjust the clutch via the external linkage. Everything seemed normal. I left to plow snow no apparent problems. However, when I returned, there was no resistance when I pushed on the pedal and there was loud chattering or grinding noise as if trying to engage without pushing in the clutch. I had to shut down before I could stop the tractor. When looking through the hand access hole underneath. The Release Yoke, was not connected to anything and the 3 Release Arm's, were laying just inside the access hole. Haven't pulled it apart to see what's going on yet. Has anybody ever had this happen or heard of it happening before?
