460 PTO

Hello,
I'm new to this forum. I've searched and read through here and cannot seem to find the answer so if it's here please by all means point me in the right direction. I have a 460 Farmall, with a PTO that will not stop. I brought it is a few years back for an overhaul and while it was in it had the same issue then. At the time he adjusted the bands and was able to correct the issue. I have looked around to find out where the adjustments are and cannot seem to figure it out. Can someone please let me know where I can find these and how to adjust. I can send pictures if that will help.

Thank you.

Hello and welcome. Someone will chime
in and help. I have Fords and know how
to do that on them but not Farmalls.
You might get a quicker response down
on the Farmall forum. There is a welth
of knowledge on this site.

believe the adjustment is similar to my SMTA with independent PTO. There are 2 screwdriver head bolts that have a jam nut on them on top right side of the independent pto box on the back of the tractor. one of them is for the brake band and the other for the "load" band. If I remember correctly the front one is for the brake. I would suggest getting an operator's manual for the tractor as it covers this as well as many other important adjustments including TA.

Two different types of pto units. Early model are planetary like older Farmalls and then they switched to the over center clutch type. Most likely, you have clutch type if it won't shut off because planet unit rarely have that problem and it is very common on clutch type.

Only external adjustment on clutch type is the linkage. It should have a definite spring feel about half inch before it latchs in off positon. Some times more will help, usually not.

The lever has no latch positon in the run positon. The handle should hang free when engaged or damage will occur to internal mechanism.

If you do have planetary style, there are two screws under that little cover on top. With latching lever between the on and off positons, you want equal movement both ways to feel resistance when moving lever to on or off positon. Tighten screws down to snug with latch centered and then back each off about one and half turns. You will be able to feel which one if for brake by playing with adjustment and lever. Actually, if in good condition, you should not be able to turn shaft by hand in middle positon but with a short like 6 inch punch through hole in shaft, turn with some effort.
