TC35A won’t move

[Notavegetarian]

Was mowing the roads, then moved up to a small field been rolling along a good 4 hours. I wasn’t mowing fast was in low range and third gear moving about 3 mph or so. Had made several passes. It’s starting to bog down a bit not too much it’s a big ant bed got past it rpm’s picked back up and the tractor stopped moving. Engine is at PTO rpm, PTO is spinning. Thought maybe I had knocked it out of gear. I disengaged the PTO lifted the mower, tried every gear, mid rang, high nothing. Did not hear any noises before it stopped, no jerking nothing. Let it sit there overnight, checked all the fluids, looked to see if anything may have popped up from underneath and wedged into anything. Just in case it was to move I had the trailer in front of it ready to load. Started up fine, nothing in low range, tried mid range nothing, felt it lock in high range and it moved. Drove it on the trailer. Does anyone have any ideas what may be going on with it.

Sorry gang noticed I didn’t have the year and model. It’s a 2006 TC35A. Stays covered, or in my shop. Try to keep maintenance up. Any ideas what’s going on. It’s has about 650 hrs on it. Use it to mow the roads and small fields, carry stuff in the bucket.

Plugged filter or strainer possibly?

Linkage bent, maybe?

The fact it moved in high range says the issue would probably be in the range portion of the transmission. No low or medium range, right? So what do you "feel" when shifting the range into low, neutral, medium, and high? Can you feel distinct positions where the detents hold in place? If so then the levers and shift rails are working as they should, and the problem could be a sheared roll pin on a shift fork.

Have it off the trailer and in my shop. Will take a good look at it tomorrow. One tech told since I had the lift cylinders rebuilt the maybe some trash or clogs in the hydraulic system. I’m changing all the fluids tomorrow as well. Will let y’all know how it goes. Thanks

Is it a hydrostat or a gear drive.
Either way I'd be looking at the range shift linkage.

 

[Harry in Ky]

I find it interesting that people come in with problems and/or questions concerning possible drive or transmission concerns, yet don't bother to mention what transmission version they have. The details DO make a difference.

 

[5030]

Probably a hydrostat. Most smaller units are today. Very few gear drive units below 75 horse today.

It’s a 35 hp 12 speed hydrostatic transmission, 4 wheel drive.

Did take it off the trailer and it shifted through each gear cleanly locked into each detent . I’m at a loss as to what happened. It’s in my shop. The tech that rebuilt the front cylinders earlier this year said there may be a bit of trash in the system. Ok I’m changing the fluids now. Will let y’all know if I find anything in the oil
