Right side track keeps locking

Hi, I am having an issue with my tracked Troy-Bilt where the right side track keeps locking. I can run the machine for a few minutes and it will go forward and pivot right and pivot left no problem, but then I hear a "click" and the right track locks. If I put it in reverse and then back into forward it will unlock. Also it can lock when in reverse and if I put it into forward it will unlock for a short time. Any help as to possible causes would be great. I have to reverse and forward to unlock many many times while doing the driveway.

Thank you!

Is it possibly loose and coming off the track or maybe has a bad bearing in one of the wheels?

What is the model#?

Garage:
MTD....2 stage(modern 8.5 HP) not my favorite
Honda HS622 TA-B - acquired at an auction- nice machine for it's size.
Toro S-140- Picked it up on trash day... it runs, sort of.
Yamaha YS 240 TB "Ricky" latest Craigslist find- on the bench now.

Hi, the manual number is 772C0767, and when it locks the track and wheels all do not move, but the left track will pivot.

It sounds as though the axle is binding, and the manual number does not allow me to look up the schematics. Is there a general generic number?

Like 4510, or 210?

I found a manual. In the end of the manual it has a parts diagram. It looks like there are some chains on the drive train. Each track has a separate chain and drive system. I wonder if one of your chains needed tightened.

On page 30, I would also look at #32. It too may also be a source for axle play.
