I have a 1954 shaw tractor.
This just started to happen.
When I release the clutch the gears engage but seems like the drive shaft is binding. No movement to rear end.
If I lift the rear end up wheels spin.
Trans is ok its Jamed between the trans and the pinion gear I think.

Welcome aboard Woody, someone will be along to help you figure it out I'm sure.

Welcome to the forum. What model Shaw are we dealing with? Is it trying to kill or bog the engine down when you let out the clutch? Can you push the tractor and roll it in neutral?

[Woody1723]

Thanks. Yes the tractor gets bogged down it cannot be pushed or driven but the wheels do turn in opposite directions when I lift up the rear end up..

Also when I take off the transmission shift cover I could see the gears engage when the clutch is released but seems jammed between the end of the trans and the pinion?.

Is a small yard tractor

That is an R series tractor. The fact that the wheels spin in opposite directions means that you are going through the spider gears in the differential. You're not turning the ring and pinion. I would say the most likely cause in that tractor is the pinion bearings. Seems like a common failure in those. If the trans was locked in 2 gears it wouldn't sit and idle in neutral without the clutch pushed in. I can't see that driveshaft locking the tractor up.

Thanks for your help, that seems like the spot to start at.

My first check would be the rear end oil level.  If low, fill it and gently try to move the tractor to get oil in the pinion bearings.  If full, you will have to get into the rear end.  If you need a parts list or help, just ask.  Nice looking tractor.

Thanks. I will check that also.
