Super M clutch or tranny problem?

Hi, my husband's Super M is stuck in 1st gear, he down shifted, and then couldn't get it out of gear.

He split the tractor hoping it was the clutch, but even when split, the gear shifter won't move.
Does this mean it's the tranny rather than the clutch?
The clutch "looks fine", throw-out bearing works. He just got it split and had to go to work, so I thought I'd ask for him.
thanks in advance!
 
Common problem, the end of the shifter is wore, and now its hung in 1st or in 2 gears. Cure is to build up the end of the shifter by welding and cutting it back down. Then the shifter rails need to be re-aligned back in neutral, and the shifter re installed.If youll search the archives, youll find all the info on fixing this.
 
What a good wife.

He should have asked you before picking up his wrenches. You would have asked us and we would have told you it is the shift lever.

It has to come out and weld material added to the tip. It is a common problem.

Once the shifter is removed, a stout screwdriver can be used to line up the shifting rails.

You can also buy a repair thing-a-mug-jig that corrects some of the sloppyness in the shifter lever. I have one sitting on my desk but don't have the packaging. I bought it on eBay. It also replaces the 5/8th plugs (Welsh plugs) that will be destroyed when removing the shifter
 
I appreciate both replies. I need to add that the tractor was stuck in 1st, even with the clutch pushed in.
When he turned it off, he couldn't restart it because pushing in the clutch didn't disengage the gears, and as you know you can't start a vehicle while in gear...

Does this change anything?

Boy, am I hoping your first answers are correct!
 
The tractor has no interlock to prevent starting in gear, but it would do no good to start it with no way to change them, or find neutral.
The tip reshaping is covered by dimensions and pictures in the "search for" box. There will be (probably) thousands of hits, so be patient. Jim
 
ok, how would he know this? The 3 fingers all were retracted on the pressure plate when he pulled it apart...they all look the same, and the wear on the throwout bearing looks even.
The only other thing I know is he thinks the clutch pads looks fairly worn (maybe down to 1/16 inch), and wants to replace it while he has it split.

Any best place to order one would be much appreciated!
 
Husband says to tell you he agrees, should have asked me first, lol.

A search on ebay for welsh plugs turns up no repair thingy for tractors, any idea what to search for?

Thanks!
 
Yeah, I meant "it's very difficult" to start when in gear because of bucking or dying unless the rpm's are way way up...

I searched for stuck in gear before I asked my question and saw all those posts, lol. Thought this might be different because of clutch not disengaging the gear...

What you would be looking for is a 5/8 inch Welch expansion plug. The IH part number is 172529 but they get about $2.50 apiece for them. Go to NAPA or another auto parts store and you should be able to get them for less than a buck apiece.
 
Actually, it's my error. I think it is spelled Welsch.

Some people don't bother replacing them. They just shove in a 1/2" bolt and maybe smear some caulk or silcone around the ends. Or maybe take a coin and do the same thing.

Well, your husband learned the hard way. Perhaps he should consult this board in the future. It's a great knowledge resource.
 
If you are saying the engine won't turn even with the clutch pushed in there's more of a problem than the transmission locked up. Engine should still crank with clutch released even if the transmission is locked. Unless there's a problem with the clutch not releasing or maybe the starter jamed in the flywheel when trying to start tractor. It would unjam when the engine was removed if so. Like the other posters said the transmission is probably in two gears, the shifter jumped slots and let transmission get in more than one gear. If he gets the transmission fork slots all lined up in neutral the shaft the clutch plate goes on to drive transmission should turn by hand.
 
No, I'm saying that he down shifted into 1st, then when he pushed the clutch in to up shift, it kept running forward, AND the gear shift lever would not move...so he just shut it down.
 
You are saying the tractor engine drives the rear wheels with the clutch down (pushed in).
If this is the case the clutch could be stuck to the flywheel. In which case it is easy to fix when apart. The pilot bearing in the engine flywheel to clutch shaft could be jammed and driving the clutch shaft, but that is about it, and it is now removed from the FW.
Is this tractor a Super M TA. If it is it is a whole different ball game. Stuck in gear can be a TA clutch adjustment. Especially if the tractor is on a grade that tries to make it coast backward. If the lever is stuck in 1st, the way to get it free is to push the rear tires forward to relieve the pressure on the Trans. Jim
 
Sudden failure of the clutch not releasing is often caused by one of the clutch lever pivot pins coming out of the cast plate. It is almost a such thing if the pins are installed backwards. The cotter pins will wear off rather than the head of the pin taking the wear.
