Mf 65

EDITED:
He said he could engage the PTO with the clutch just fine. When he tries to disengage the PTO , using the clutch it doesn't release. Sounds like a clutch malfunction to me.

I went to www.agcopartsbook.com and looked up the clutch assembly on a MF 65. No hydraulics involved here. Purely mechanical as I thought. There are clutch levers that the throwout bearing is probably hanging in. The OP didn't mention whether it's a single or duel stage clutch. The single stage clutch is somewhat simple design. The duel stage has quite a few additional parts that if came loose could cause this hangup. Inspecting the clutch thru it travel via inspection plate would be my first coarse of action.

I'll wait for a better description of the problem from the OP. The problem is pure speculation at this point.

There is no problem with pushing the clutch in and activating the pto. The problem is when you pressing in the clutch and try to disengage the pto. Today I tried it and it worked. Yesterday it would not disengage until I cut tractor off.

sounds like the sliding gear or lever hanging up. That my take on the problem.

I always tap the pto lever with my heel while dropping rpm's to get the load off the drive train, this will pop it right out I am sure this will work for you.We had 2 65's on the farm and I spent a lot of hours on them as a kid.Give it a shot.

Try lowering your RPMs since the gears are not synchronized. My 135 does that on occasion then i'll lower the RPMs and it drops right in.

So it's not the clutch. does it shift in and out easily when the engine is off? You may need to rotate the PTO shaft by hand to get it to line up. Then check the movement of the shift lever, if it shifts out about the same with the same pressure as it shifts in the problem is likely torque on the drivetrain as I mentioned in my first post. If there is a big difference it could be the detent in the lever on the PTO lever cover. If you remove it you will have to drain off some trans- diff fluid.
