I have a clutch stuck on my Mitsubishi 2wd tractor. I have tried to start the tractor with the clutch pushed down, I drove it around for a couple hours and it never disengaged. I tried different gears, gave lots of gas and hit breaks. This has work previosly. I would love to avoid splitting this. Any other thoughts? Is there any way to access the flywheel to get a screw driver in there to break that without taking it all apart?
