M7040 4wd problems

[budlite8]

I have a 2011 M7040 4wd, my problem is that the 4wd stays engaged, I got under the tractor and physically took it out of 4wd, the light went off and all worked fine in 2wd. I was able to put it in and out of 4wd, but now it's back to staying in 4wd, I can pull up and down on the lever, but stays in 4wd, but I can go under the tractor and take it out, and it stays in 2wd until I use the lever to place it back in 4wd, then it stuck again! I think it may be something to do with the linkage, but this is in a very tight spot and I possible would have to remove the fuel tank to access it unless someone has a better idea.
Any and all suggestions are greatly appreciated.

If it's a 2011, is it not covered under warranty?

You don't explain what you do to get it out of 4WD while you are under the tractor. It must be moving a lever or some such maneuver.

The engagement/disengagement lever by the seat should move the same linkage that you do by hand. Look for a loose or missing pin.

If there is a turnbuckle for adjustment then that may be the issue.

Call the dealer and maybe he/she will send someone out for a look.

Linkage needs lube.

I have to move the linkage that is connected directly to the transfer case.. When I move the lever by the seat, the linkage by the transfer case does not move any..

 

[budlite8]

The warranty would cover the transfer case, but not any linkages,etc.. been down that road.

Have you tried moving the tractor forward a tad while using the lever to disengage the 4 wheel drive?

It could be that it just needs a little relief of the gears to release.

If that doesn't help then I would check the linkage to make sure it hasn't gotten bent, or lost a pin or the turnbuckle hasn't loosened a bit, or it could just be due for adjustment.

The adjustment turnbuckle should be under the tractor where it is pretty easy to get to.

Good. At least you have isolated the problem to be somewhere between the lever and the transfer case. It is not inside the case so can more easily be dealt with.

Something in the linkage has to be loose, binding, and/or out of adjustment. It sounds like you already know that to be the case. Now access is the issue.

I'll look at my M7040 later and see if there is a way to get to it that you may have overlooked. Something as "simple" as taking off the rear tire may open something up.

Since you have explored the dealer/warranty aspect you may want to call again and ask how to get to the linkage. All the dealer can say is "I won't tell" and you have lost nothing except the knowledge that another dealer will get your future business.

I always push my out of 4WD on the go. Sometime I have to turn a little but it snap out fine in time.

I dont know about the M series but my little beast wont come out of 4wd unless you are just moving a little bit, takes pressure off the grears I guess, same with Hi to Lo and back

I just went through the same thing only mine wouldn't go into 4WD. I have the same tractor and it was the linkage that was sticking. The dealer removed the rear wheel and fuel tank to get at the linkage and they coated everything with white lithium grease. Has worked fine since repaired.

^^^That post give me an idea. Maybe a rock, mud, or other debris has somehow affected the linkage.

If you have a power washer, stick it up under the gas tank and blast away for a while - maybe it will loosen something up. Later, hose it with WD-40 or the like.

It is worth a try before tearing into the tractor.

Grease will tend to pick up dirt and debris making it harder to remove in the future. But...whatever works.

The real question is: Did r40kh's dealer do the repair under warranty? Despite what the OP's dealer said it seem that if something is not working under the warranty period it is the dealer's responsibility to fix it.

Yes, all done under warranty as the tractor is less tha a year old with only 50 hrs on it. The dealer was great ..sent up a trailer picked it up and was ready the next day
