I bought a 1085 tractor for 6800 now I find out it needs an overhaul and main and pto clutches.
Is it worth fixing or not? I would also like to know what years they made them.

I have a 1085 that has hyd. problems. I'm in the process of tearing it apart to replace the hyd. pump and pto clutches. My multipower started shifting in and out of high range. About 1 - 2 hours later, the pto shaft started bogging down with the slightest pressure. Operating the tractor with the weak hyd pump burn't up my pto clutches. It is going to be a long job. Never had any other problems with the tractor before.

The 1085 is a good tractor, the PTO has an update kit to make em better, I put one in my dads a few years ago, the engine clutch is no big deal, a fairly easy tractor to split. I would do some hydraulic pump test to see if it is good, If you don't know it is bad, replace the cluch and put it back together, u will have to rip it all apart again, u have to take the pump out anyway when you change the pto clutch disk. Is the clutch workable enough to tell how the Multipower works, (if it has one) You will be right there also to change them if needed. Another thing you can do is remove the hydraulic filter and cut it apart and check for metal. If the PTO disk went and metal got into the filter and inhibit the oil flow to the Multipower clutch causing them disk to slip and eat themselves up. If the motor is good and u can do the work yourself I would remove the saddle tanks, split it, roll it apart a good distance, do the engine clutch, take the tranny off the back end, You have to remove the steering wheel and the dash, it removes pretty easy also. then having a good book go through the procedures to remove the PTO and check the multi-power disk since u r there. e-mail me I am sure I will remember some few fine points about this.

the multipower works great, the reason I think the pto clutch is bad is because the main clutch has'nt gotten so bad where the tractor slips just bad enough so I can not putt it in gear all the time, and yet the pto will not turn off unless under a heavy load. Every one I have talked to told me that was the pto clutch then aswell.

There is a PTO brake on it, you are saying it works ok but it won't shut off? There are O rings in there that if is blown the PTO brake won't apply. I guess I am wondering if it drives OK. There are also these wavy springs that go around the outside of the disk that are suppose to push the main piston back. That was the update, the new springs were much heavier. I am working 3-11 shift starting Wednesday and will bring my massy manual to work and check it out if u have any questions. The pump that drives the multipower and PTO are in the same unit but are two separate gear pumps. There is a test port on the firewall I believe. If that pump is not putting out it won't stop or if there is an internal leak. I wanted to test mine before I put the cab back on the tractor and had all the oil going through the pump dumping back into the transmission. The PTO would not stop then I realized I must hook back up the remote valve lever so it will build pressure and apply the brake, after I did that it stopped. Give me a shout if I can help, I got a boring job and this is a great way to pass time.

MF-1085 : from 1973 to 1978; I have one; it is a nice, not expensive winter job if you know what to do and have access to a heated, well equipped garage.

Sorry to hear!! We have a 285, which is the utility version. It is a very good tractor and has been pretty faithful. You wouldn't be able to sell it for as much as you paid in it's condition, but it also would be cheaper than fixing it. On the other hand, once you fix it, it would make a good tractor. The perkins in these tractors is a real workhorse, ours just rolled 5800 a few weeks ago, never been opened up. We used to pull 3-16's with it, and we still do most all of our other feild prep with it(it has duals, and lots of weight on the front when we need it) The 285 might be a little handier, but the 1085 is also a good tractor from what I understand. I only saw 2 in my area though compared to the 285's on almost every farm
