hello tractor was not run for 18 years try to pull it clutch in or out or in or out of gear goes about 10 feet then locks up the rear end any ideas. a little play in gears but not enough to worry about thank you

I had a similar thing with a WD. I never did find out the cause for sure but here is what I think was going on. It too sat for maybe 20 to 25 years. Had real mud for lube in the finals. I think all the mud settled to the bottom and plugged up the gear teeth. When I jacked it up to make sure the brakes were free to move it the right rear would only turn about 3/4 turn and stop. By working it back and forth quite a bit it finally freed up,and when I got it home and took off the pan I could find no mechanical problem. Because you are getting about 10 feet of movement I feel it is something like this as all other gears would turn more than once around for this much movement. Only the rear wheel bieing so big would only move less than one turn, the axles would turn several times because of the bull gear reduction, (step-up when you turn the wheel). Hope this helps, let us know how it works out, I would be interested what you find.

hello there was a little bit of rust in the gears so that could be the problem . the only thing that bothers me is that when you have the backend jacked up you can turn both wheels and it doesnt lock up you feel a restriction once and a while but not every revolution thank you

Well you could take the cover off of the back of the differential and look inside there pretty easy, looking at all the gear teeth. Same with the fianls, with the wheels off or the rims out (wide) it is easy. And it isn't too hard to get the shifter cover off of the top of the transmisson,with the oil drained out you should be able to see most of the gear teeth. Just for the heck of it try backingoff the brake adjustment a good bit too. This inspection is a good oportunity to change your oils too.
