I just inherited my great grandfathers 36 A, my father took good care of it the last 15 yrs. started it regularly etc.., recently he attempted to spin the flywheel, not electric start, he said it is locked up, can turn fly wheel backwards and then it comes back to the same spot but won't go any further, any help out there? the tractor is in his barn in OHIO, I am in Bryan,Texas, I was counting on it starting to load it this spring and bring to Texas to do a restoration on it. Please advise, all help is appreciated.

How long since it last ran? Will the flywheel continue to rotate backwards and not stop or? Also has the temp been below freezing where the tractor is located? If so there may be some water in something that froze.

Valve stuck? Ron MN

I was there in Ohio in mid-Sept and dad started it, as for water in the engine freezing? it is in a barn but yes it is that cold in Ohio, but are you thinking water in the oil inside the engine? don't know about how far he can turn the flywheel backwards, will ask my brother to go and check it this weekend, dad found this problem this fall when he tried to start it prior to draining the water out of the radiator and get it ready for winter.

not sure what your response means, or is intended to mean.

I was thinking if there might be water in the reduction gearcase it could have froze. But like another member mentioned, an intake or exhaust valve could be stuck. Meaning it could be stuck closed and the not able to open. Or I don't know if it was stuck open, if the piston would hit the valve or not. Either way do NOT force it. I would pull the valve cover and at least have a look while rocking the flywheel if it were me

Have him take the spark plugs out and try it.

You said that this happened before the water was drained from the radiator. So I would assume that it was before anything froze up. So that would eliminate frozen water in the crankcase or other gear housings. So that would leave me to believe that it would be rust causing a stuck valve or rust on the cylinder wall. There's always the possibility that the head gasket rusted from years of using plain water in the cooling system and that allowed water to enter a cylinder bore and hydro locking the piston.

Congratulations on receiving a great piece of family history. Have something in common with you but not the same circumstances. My late uncle owned a 36 A and I remember him cutting and raking hay with it back in the 1950's. I was fortunate enough too acquire this tractor but had to buy it from a neighbor a few years ago who had gotten it many years prior at my uncle's retirement farm auction and had restored it and was talking to this fellow one day and he asked me if I would be interested in buying the model A tractor from him. Of course, I took him up on that offer and since have used it to do a little plowing and a few parades.
Keep us informed of the progress on your project.

ALLEN1964 · Feb 7, 2023
