Mahindra 6000 4wd tranny problems?

antks · Apr 26, 2006

I have a 6000 that is having a problem pulling it's own weight in high gear. One of the helpers was on it a few days ago, and he said it just "quit on him". The problem only seems to occur while in high gear - in low gear the thing goes just fine, but of course its very slow. Also, the tractor seems to be fine when its cold, but after a few hundred feet it will just stop. Sometimes if I let it sit for a second it will seem to catch and get going again for a little while if I rev it high. I will say that it was very low on hydraulic fluid when I checked it after this problem came up. I assume since there aren't any problems in low gear that it isn't a clutch problem. Is this a poblem with he hydraulics? Is the tranny fried? Any ideas before I pay my dealer a small fortune to fix it?

Thanks!

Well if it's not revving high in high gear I would say it's not in the clutch. Could it be starved for fuel? Perhaps filter clogged?
Could you elaborate a little more on the problem? Is it hanging up or just dying? Shifting easily or hard?
Doesn't make sense! /forums/images/graemlins/smirk.gif

It will rev high in high gear - and it isn't dying at all. The problem comes while in high gear just getting the thing to move. It's like the transmission isn't engaging and moving the wheels. The best part is that it only happens after you drive it for a bit. I mean, I can get it out of the stall, drive it out into a pasture for a few hundred yards and everything seems fine - then all of a sudden it will just stop moving.....engine still running and still in gear. But, it always seems to move just fine in LOW gear. Now to make it even more confusing /forums/images/graemlins/smirk.gif if you let it sit for a minute, then rev it really high, it will slowly start to move again for 20 or 30 feet then stop again......and you could do that all day.

thanks for your reply

Your clutch needs adjusting. Anytime a vehicle won't hold in high gear but the engine runs, its the clutch. Also it would seem fine in low gear as the momemtum of the gears will carry it forward. Check your freeplay on your clutch pedal, you should have about an inch or so before you feel any resistance. DO NOT RIDE YOUR CLUTCH! This means don't even let your foot rest on it while you are working. BobG in VA

Let me try to give you another scenario that may help explain. I have a 1984 Nissan 4x4 5spd. Recently, while in 2wd and high range it started to stop moving. I could put it in 4wd and low range and it would move fine. Of course, it turned out to be the clutch, which was slipping bad, but the lower gears didn't need as much force to make them move.
Now to your problem. I would have to say that either your clutch is wearing, or you may have burned up your hydraulic pump and/or sheared your hyd oil. I don't know if the lack of oil could burn something up that would stop it from moving, but I would assume it could be related being that you said it is fine until you get it hot. Usually a slipping clutch will slip all the time, cold or hot. If you have the flow through hydraulic system, this could be the case.

Bob is right it's your clutch freeplay. If the clutch is not too badly worn it will adjust out with a little effort. The owners manual details how. Mine started slipping under load at about 200 hours, but once adjusted I haven't had any more trouble. I doubt being low on hydraulic oil has hurt it unless it was completely empty or run like that for a substantial period of time. Keep us posted on your problem.
It will help you get responses on your posts if you fill out your profile. Folks are always suspicious of a problem with no profile. Seems folks do that to try to put down a brand.

Like others said, check your clutch adjustment. It takes more of load to take off in high gear than it does in low. Mine did the the same thing @ 200 hrs.

One of the helpers was on it a few days ago, and he said it just "quit on him".

Do you think one of the helpers could be not knowlingly riding the clutch? Do they know anything about tractors?

Just a thought.
