Hey looking for some insight on some issues. Recently purchased a 2001 kubota m5700 i got it for very cheap because it is stuck in reverse (manual shuttle shift) also if you engage the pro and let the clutch out the tractor will bog and die. It drives in reverse no problem. The previous owner said that this happend a couple times before but he would wiggle the shifter and it would pop back out. But the last time it happend it just stayed in reverse.

It won't be cheap after you split it or have it split. You have internal gearcase issues.

Even if you put an additional 5 in it, you will be ahead.

If I were you (I'm not), I'd take it to your local dealer and tell them to go through it and make everything right.

What I did last winter with the M9 I bought used. I had them keep it all winter (slow time for them) and take care of every issue they might have found and they did. Cost me 4 grand as was worth every penny I spent. They used it for 'make work'. Even kept it in the heated shop all winter.

I basically have a 2002 M9 that is 100% issue free now.

Stuck in reverse sounds similar to a M4900 I once owned that hung in reverse. The synchronizers in sync-shuttle were worn out. I had tractor split & sync shuttle replaced. Engine loosing rpm's when pto is engaged is a totally different problem from shuttle

Too bad in a way that you cannot remove a top cover to access the gear sets (like the old Muncie top loader). That would eliminate a split to access. Splitting a unit is the expensive and time consuming part and on a bigger tractor involves dealer / shop time. Not an in the garage at home deal like the little ones.

So just looking at it again yesterday and looks like I was misinformed. When you engage the PTO the tractor does not stall. Only when you put it in forward. But i moved it a bit with my excavator and it deffinetly sounds like something is broken in the tranny. I am going to split it next week

Does it ever roll free? Low-hour failures are not common on this model. Start with the WSM and study, poke & prod until its clearer where the problem is. Lift a rear wheel, rock it back and forth, clutch pedal up, down, etc. to isolate where the lockup is. Some of the shuttle linkage can be seen under the floor on top of trans.

Mechanical (gear-type) shuttles are fairly simple. A shift collar slides back and forth, engaging either forward or reverse. My GUESS is the linkage isn't moving it far enough to disengage reverse before starting to engage forward ( and locking up). Best not to force the machine to move this way - its pretty robust but it would be a shame to break something expensive because of a worn or loose linkage.

Mechanical (gear-type) shuttles are fairly simple, a sliding collar moving to engage forward or reverse. My GUESS is the linkage isn't moving it far enough to get completely out of reverse before partially engaging forward. Best not to force the machine to move this way - its pretty robust but it would be a shame to break something expensive because of a worn or loose linkage.
It will roll forward only in neutral. When you put it in forward and in gear it wont roll. But another thing i forgot to mention is that when you put the shuttle shifter in forward or neutral the tractor goes backwards. And you cant put the shifter into reverse. So the only 2 positions i have are neutral and forward wich now both act as reverse

Points to a possible linkage issue. Attached pdf's are parts drawings of the hand lever and the links. Take off the inspection plate under the floor mat. Start by confirming that all appear to be undamaged and moving normally.

Try disconnecting and inspecting for free motion. See if it might shift ok without using the linkage (using vise grips etc.)

If it looks like there's a problem further inside, someone here or on TBN might know if the cab can stay in place or maybe just lifted a bit for splitting it.

Customary cautions for working under a tractor ALL APPLY. Dick B

I have a M6800, couple of years older. I had a gear to break just outside of warranty. If something like has happened it is possible you have a broken piece inside the transmission affecting shifting. Why don't you drain the hyd oil and filters and see if you find any metal in it. I would run flexible magnetic in to see if found any sign of pieces of metal.
