A neighbor down the road thought the same thing, although since he doesn't own a tractor it is more understandable. He rented a TLB, got it stuck and then told me "This cheap thing only drives with one wheel!" and I said "Uhh... I think they all do." I showed him the differential lock and that did the trick. If your tractor has a differential lock I think it is a pretty fair bet that it doesn't have a limited slip differential. Although maybe there's an idea for an aftermarket customization! Who wants to manufacture them?

Well, I tried. I don't see where everyone has to make a big deal out of it though........I thought the tractors diffs. are like those on a truck......Sorry. Lets just forget about it.

You TRIED what? To give someone bad information because you wanted to be part of a discussion? Even worse, to state someone else was wrong with what they presented when you don't have the first fact to support your position? Several people (I do not claim to be one of them) here have tried in a truly patient and kind manner to ask you to recognize your limitations, yet you seem either unwillling to heed their advice, or incapable of understanding it. Me personally....I am simply opposed to bad information being given out (Remember? That's my biggest complaint against many recon dealers) for any reason.Travis_R said:
Take a hint and don't STATE something as FACT when it is nothing more than your feeling or belief. You create your own trouble. You can't keep doing silly things like this and then say "sorry, let's forget it" and expect it to all go away. You have a lot of ground to make up before many of us will give any credibility to anything you claim or state. You can start making up that ground by reading and learning, rather than interjecting some inaccuracy or some half-baked excuse. I really think most of us would truly rather have you do some maturing rather than just go away....but you have to want to grow up first.

Hang in there Travis. You can learn alot here from experienced people.
I'm still wondering from the thread starter if this tractor is a regular run of the mill used Yannie or was it a "Recon/Refurb" unit????
Travis, hang in there and learn. You got to walk before you can run. Lots of expertise on here, listen to em!

A truck differential doesn,t work like that either.

Well everyone has strayed from the question.
The '4wd', as I understand it works this way:
When engaged the drive to the front and rear is locked together as there is no differential in the center 'transfer case'. This is like older jeeps and non full time fwd.
So, if the engine is running, the trans is in gear and the clutch is out at least one front and one rear will be turning.
Assuming all four wheel have equal traction all will be driving.
But, since open differentials transfer power to the wheel with the least traction, if one spins the other has the same amount of power applied. If that isn't enough to move the machine, you're stuck, unless the other end has enough traction to move you. Usually, when the rear diff lock is engaged, locking both wheels together, and forcing both to turn along with at least one front, you can move.
Now the poster says the machine pulls to one side when 4wd is engaged but not when in 2wd.
This would indicate that the hubs and axles turn freely when not being driven. The only way I can see that 4wd would make it pull, is if the differential is somehow fouled up so that is does not divide power as designed AND one axle is not driving. If only one axle is broken or somehow disconnected and the diff was working ok, everything should just spin in place with no drive and no steering impact.
Anyway, the earlier suggestion to speak to the selling dealer is still a good one. If that doesn't get it fixed, then if it were mine, I would jack up the back and front, place on jack stands and start troubleshooting.
start it, put it in gear and watch wheel motion. It should be apparent at that point what is or is not happening.

I fully agree with what Satohbull says. The purpose of a differential is to allow the two driven wheels to rotate at different speeds when going around a corner. The differential supplies equal amounts of torque to both driven wheels. If one wheel loses traction(in an open diff such as your tractor is more likely to have) then the amount of torque provided to the other wheel will be the same amount as to the wheel losing traction. Hence you see one standing still and the other spinning.
Did you check the oil level in the front axle? I also think that there is something wrong with the diff or it could also be that there is something wrong with the gears taking drive down to your left front wheel causing it to bind or turn more difficult when 4 wheel drive is engaged and torque is applied to those gears. I think it is pulling right because more torque is applied to the right hand wheel when 4X is engaged.
