Help! The pto is stuck on the model 50 that I recently finished restoring. The engagement lever will push down some but won't pull up to engage the pto, it is just frozen when pulling up. Also you can't turn the pto shaft by hand, but can turn it with a pipe wrench, but there is resistance. I bought the tractor last fall and the pto worked, however when I pulled her out of the garage after restoring, it wouldn't move. I didn't touch anything with regard to the rear end or pto so not sure what happened. It was in a heated garage all last winter so nothing could have frozen up due to water or something. As I mentioned earlier, the arm that the linkage attaches to on the right side will move up some when the lever is pushed down, but when trying to pull up she is tighter than a drum and will not move at all. Anybody have any ideas? Like I say, it did work, but now it doesn't, and I didn't touch anything in that area. I do have an oil leak back there, so it could be low on oil, but I haven't checked into that yet. I wouldn't think that would cause the whole thing to freeze up altogether, but I could be wrong. Any suggestions would be appreciated! Thanks in advance! Also, which direction (right or left) does the foot lever go in order to allow the pto to engage? This is the lever down by the gear shifter. It might be important to also note that this lever does seem to work okay, but only if the tractor is shut off. It just grinds when you try to engage it with the engine running, clutch in or out. Thanks!

Sounds like your PTO clutch might be stuck engaged. To confirm, move the foot lever to the left to connect the PTO drive shaft to the engine. Do this with the engine off. You may have to bump the starter a time or two to get the gears in mesh. Then start the engine and observe the PTO shaft.

I have found that a balky clutch can often be disengaged as follows: Attach the PTO to a moderate load that is not working but has some inertia (a 5-6 ft rotary mower would do nicely). With the PTO gear (foot lever) engaged, start the engine on low throttle. (Everything will start up so make sure load is clear.) Gradually rev the engine to full throttle, then quickly pull the throttle lever all the way back, so that the load is trying to keep the engine turning. Try to disengage the clutch while the deceleration is going on.

If it's still stuck you'll probably have to take the clutch assembly off to get it unstuck. It's not too bad a job. An I&T Manual would be a great help. Be carefull--the engaged clutch pack is spring-loaded.

When you get it all back together, fill the housing with light-weight oil (SAE 10).

Guy, Floor board lever engages to the left always have engine off to engage!!! Once this lever is engaged then pick up the pto lever beside the battery box to lock position. If tractor engine pull down or stalls then u have problems.

The PTO on my 50 is transmission driven, so the only thing I can answer in your case is that the PTO engaging lever by the shift quadrant moves to the right for engagement. It should engage with the clutch lever back even with the engine running. Don't give up.
