Hi, went out to start my 961 diesel to run some fuel through it as it's been sitting since fall. It's kept in a heated garage, I don't use it for snow removal. It started fine and it went into reverse but that's about it. Once outside I couldn't move it into any gear from neutral. When I depressed the clutch pedal and tried to move it into gear it would just grind. I tried adjusting the pedal for more travel but that didn't help, would not go into any gear. I'm assuming the clutch is shot? A friend mentioned that the clutch might be stuck. How would I check that? I can start it in neutral but not in any gear to jar it loose. Any comments would be greatly appreciated. Thanks, Terry
