Question ...I own a '59 sos never had issues till one day neighbor was moving things out of his garage ..my sos was stored their and I had carburetor off for repair .. He decided to pull it out .. When parked it it ran moved great...when I reinstalled carb it runs great but wouldn't move in any gear sounds as if the pump is running but zero movement. Well I drain trans oil as it needed and stuck a magnet in drain hole came out spotless I put magnet in again. And pulled out a snap ring about half I ch I. Diameter ...any clues to where it goes or am I going to have to split the tractor? Thanks ahead Dave

If your neighbor pulled it out and didn't slide the tires he used the disconnect. Ask he what he did to move it and have him show you how to work the disconnect.

Or the bands were backed off.

Can't help on the snap ring situation but if it was moved without the carburator I'd say the transmission disconnect on the left side has been rotated to disconnect. May have to wiggle the tractor a little sometimes to re-engage.
Pull up the parts diagram to see if you can find that size snap ring before doing any splitting. Find someone who knows how to tear into one of those also would help a lot. Get/follow the service manual directions to the letter.
