My 350 U tractor suddenly will not move. The TA always seemed to growl in low side, but worked fine in handle forward position. I can shift transmission through all gears, and reverse, and it will grind like crazy and occasionally try to move. I don't know if its a clutch problem or a TA problem. How do I find out? How do I replace clutch? Split the tractor? Where at...the front or back of transmission. Is there a book on this? I've never done it, but to have the "man" do it will be too expensive. I'm ready to rip and tear, but have no clue where to begin. HELP!

Turns out the planetary gears of the TA are broken. It may need a little clutch work as well. It's going to be expensive, but with the tractor in 3 pieces, I don't know what else to do

You may want to add some oil in the transmission and let it set for a while. It may let the clutch brake loose if stuck.

Does the engine pull down with tractor in gear & the clutch out? If not, could be the center is out of the clutch disc or the splines are worn out in the disc or off of the clutch shaft.

I think Owen has it pegged. In either lever position, power is transmitted through the TA gears. In direst, they turn as a unit, but they still are loaded and spinning. In TA they turn on each other resulting in the growl being an indication of gear death. JimN

The growling in low TA position may be an indication of the problem. The pinion gears and bearings are the only additional parts moving while in TA rather than direct drive position. Direct drive is accomplised by locking the TA carrier with the pinion gears to the TA input shaft which in turn drives the transmission input shaft all as one unit. A failure of the pinion gears or either shaft gear will cause a condition of no drive through the TA in either position of the lever.

Remove the TA clutch inspection cover and see if the TA clutch is turning when the engine clutch is engaged. That should allow you to determine if the problem is in the TA or engine clutch.

Probably your main clutch. How did your TA work before? Did it slip on the low side at all? If not, then the problem is probably not in the TA, as it is very unlikely that both sides would fail at the same time. The other possibilties are a differential problem, broken bull pinion shaft on one side, broken axle on one side, or an axle spinning out inside of the wheel hub on one side. Try starting the engine, putting it in gear, and applying each brake pedal one at a time. See if it moves, if it does, you've got a final drive/axle problem.

I am not sure, but the TA has nothing to do with it in the forward position that is direct drive. It very well could be the clutch. Have you noticed it slipping with a load prior to this. The tractor needs to split between engine and bell housing to replace clutch. It may also be a adjustment problem between clutch and TA. You need to get a IT manual it will have all these procedures in it including the proper engine clutch to TA clutch adjustments. The more I think about it it may need adjustment. I bought a 450 while back that would not move and I adjusted the cluth linkages and got it to work. Regardless you need that book they have to be exactly right by the book. The book ia available at TSC or IH and maybe on this site look to the left at the top of page and click on tractor manuals.

Sure it's not as simple as the brakes locking up? Occured on my super C after sitting a while and it was the brakes sticking.
