PTO

Well, this is kind of like k0ua's post.

When looking into the shaft's splined connection you should see one of the lands (deeper groove) obstructed by the pin.

Depress the pin until the land is completely clear of the obstruction. That is how much the pin has to be pushed to get it on. The pin is actually shaped like an hourglass.

Some pins have an enclosed "other" end with a little hole in it. If the pin won't depress far enough, then it may be clogged. Hose some WD40 (or similar) in the hole and follow it with compressed air. Check to see if the pin will fully depress now. If not, disassembly may be necessary.

A screwdriver with a blade tip can be run in the lands of the implement's PTO shaft and the drive shaft on the tractor. That should let you feel if there are burrs.

I have pushed the button in flush. I have checked the PTO for burrs. I haven't checked the attachment completely for burrs. I had to go to work today so I haven't checked out the entire attachment for burrs.

The button may be pushed in too far. That is why I recommended looking in the shaft to see how far it should be depressed to clear the blocking of the land.

The way I usually hook up the pin style is to push the PTO shaft on as far as it will go, then continuing the pressure, push in the pin. At the exact moment the pin lines up with the land then the shaft should slip on, usually too far.

Then let go of the pin, back up the PTO shaft, and the pin should snap into place.

I have seen 2 different attachments my friends have had in the past and the PTO shaft itself would not slide freely. Probably not your problem but you can check to see that it does slide freely.

It's not uncommon to get a piece of stalk or twig mashed into the implement end which will raise Cain with later hookups until it's removed - needle nose pliers or hemostats and a flashlight (and cheaters if you need 'em) can be a big help.

in one rare case i have seen a pin be able to rotate so that even pushed it is still warding the pto shaft groove. n that case, the yoke was worn, and not easilly repairable. I bolt now lives there. pull bolt out slide on.. put bolt in. not elegant. but was cheap.

I have a slip clutch with female splines that came from the factory with a bolt & nut instead of a push pin.

deffinately cheaper to implement!

If you do find out the button has a problem>
If your dealer services older tractors and equipment he should have a rebuild kit that has all the parts you need to fix it.

i remember when tsc used to sell the button and spring kit. not sure anymore.
