I have had problems with the clutch disc sticking before and now use a block of wood on my TC29 to keep the clutch pedal depressed. While it was parked this last time I found that now the release collar is stuck and I haven't found any way to break it loose. now the clutch is disengaged all the time. Any thoughts or ideas to get it loose. I've soaked it as well as I can with penetrating oil, but the angle through the bell housing opening makes getting any kind of tool on the release bearing collar very dificult. Guess it rusted due to condensation from recent rain storms. not looking forward to splitting the tractor.
