I have a Beeline Stump Grinder, 30hp Kohler engine walk behind unit. The electric clutch failed on it and the company is out of business. Does anybody know a part number or clutch that will work to replace it? So far all I know about the clutch which has no part numbers or anything on it, is that it is a 300 ft. lb torque and 4 groove style electric clutch. If anybody can help me out i'd really appreciate it I need to get this thing fixed and back in action!
