I will take a guess. Did you break the bolt off that hold the pto on. I would drain the oil, remove the battery and turn the tractor on its side. Drill a hole in the broken bolt and remove it with an easyout. I have a 178, easiest starting rig that I have.
Yup what Ed said. Might have to siphon some gas out too. Get a good e z out set and high quality bit. You get one shot at getting that thing centered and drilling straight. Not simple but certainly doable. I can’t remember breaking that bolt but yes that the motors crankshaft.
