Deutz D4006 misc. info requested

It has a Serial Number 7877/9028, and other numbers on the plate are SFE 232 6877 and A-1003-00. Can anyone give me any information as to the year model of this tractor? I have ordered some manuals, but I doubt they will have that information and I cannot find it anywhere else.

My real question deals with the fact that the 3 pt. lift seems to have an internal leak. The lift is very strong, but under a load, it will slowly drop, then the hydraulics will quickly lift back up to its position, almost to the point that it will bounce the front end off the ground with a heavy bushog behind it. It does not change much with the weight of the load, it is just more noticeable with something heavy on it.

How hard are the hydraulics on this model of tractor to work on? Is this something that an "untrained" shadetree mechanic can repair? Or is this something that I should take to someone who is experienced in working on tractor hydraulics?

Also, left real wheel seal is leaking. How hard is this seal to replace? How hard will the brake drum be to remove? Will I have to pull the axle out to replace the seal?

I also need brake shoes. Can I buy new ones, or will I be better off having my old ones relined?

Any advice that can be offered will be greatly appreciated.

There's a valve in the rearend of the tractor that is bad that causes the 3 point to act that way. You have to know what your doing to replace it, so i'd look for someone who has done one before to get it fixed..

I've never replaced a rear wheel seal, so i can't help you on that...

As for the brakes, the lineings were too hard from the factory on those models, so i'd get a brake shop to reline them instead of getting new parts from Deutz. (will be cheaper too)

Here's the number for my Deutz dealer if you need it.... 231-924-3420

Thanks for taking the time to give your advice.

I have gone to some local tractor "fixer uppers" and havee been asking others the same question. Most all of them have told me that is likely a check valve in the lift controls and that it is not too hard of a fix for someone "experienced" And, most all of them have told me that I should probably have someone "experienced" work on the hyd lift b/c I would like not be able to get it back together myself.

Thanks again
