PTO Shaft

Joe Styke · Oct 10, 2019

I have a relatively new Kuhn gyro rake (5 years old) which is the best rake I've ever owned.
Today PTO shaft will not come off tractor shaft. It will moved about 1/4 inch with collar pulled back and then stop. I have put LOTS of pressure on it to no avail.
I thought shaft might be bent but disconnected other end and it telescopes perfectly?

Maybe there's some dirt or grit that's causing it not to release the little ball or pin that keeps it on the pto. I'd get some brake cleaner and spray it well to clean it out, then spray in something like WD 40 for lube. Hopefully that will do the trick.

Found that to happen of 3 newer tractor pto shafts recently, the power shaft balls push forward, or pull back and they make a burr on the pto shaft. I had to take the snap ring off and let the balls fall out, then a little pounding on the yoke, and it came off the pto. Use an angle grinder with the sand paper disk to smooth it up, removing it often and cleaning up the shaft will keep it from getting that bad again.

The drive (pto) shafts on my corn head do that sometimes. As tight as they fit on the splines you wouldn't think there is any play from spline to spline but I can get mine by turning the shafts backward. It seams like it lets the collar release the balls a wee bit more. With rake engaged try turning the gyro backward putting pressure on the other side of the spline.
ps. make sure tractor is off while you are screwing around with this.

I also have seen this also,, on the ball type,, or jd type of collar with balls. even the newer twist collars do it somewhat with the pin type keepers... had to twist the collar off to get the pin to push in far enough.

Unhook the rake then slowly drive ahead until the halves come apart and try taking it off then. That usually works.
