Mahindra 2638 HST quit.

Update. Spent some time under the tractor looking at linkage viewing how they engage the transmission. They all look good and turn the shaft going into the transmission. Added fluid until sight glass was half full. Started the tractor and tried to back up or go forward and nothing. Lifted the front end with the bucket and engaged 4WD. Pushing the pedals made the front tires turn both forward and reverse. Put it back in 2WD and pushed pedals. The engine would labor but no movement so, it looks like the problem is inside the transmission. Will take another look under the tractor tomorrow before calling the shop. I hate being work stoppage. BTW: I did not hear any gears clank or make any noise before the failure.

Have you tried it with the Differential lock engaged?

Maybe it broke all the bolts holding the ring gear in place? Or something in the diff let go.

I tried the differential lock with no success. I have called the dealer to come and pick it up. I don't have a clue how we will load it. lol

Well, they picked up my tractor and said it may be a month to four months to get a new transmission. So much work to do and no tractor to do it.

That sucks , I have the same tractor with 380 hrs , hope it stays strong. I also have a lot of work to do coming up. Good luck and keep us informed. Have they actually diagnosed the problem ?

I have the 2538, predecessor to the 2638 (same drive train). Had it since 2017, got 1400 hours on it, and not one problem.

In fact, this is the 1st significant problem I've seen on this board for the 2538, or 2638 since 2017. Rarely do you hear of any problems at all with them.

Hopefully this is a one-off for the OP.

I went to the dealer and the tractor is just sitting there. They said there work load was backed up. hopefully, they will look at it this week. It is no skin off their nose. lol

Have you had any updates? I have one with exact same problem and my bolts thru ring gear carrier to ring gear are all broke or backed out! Does not appear they were long enough to start with!

I talked with them yesterday and they finally got it into the shop. No status when they will break it down. Will update when I know more. Did you get yours from Anderson Feed in Dahlonaga? I am also in Cleveland GA.
