Troy, you are exactly right on the operation of the PTO. I was misleading in my last post to Duane because I just took what my dealer had told me about overrun being built-in and transposed that to similar operation to the external overrun clutch I have on my Ford Jubilee. Well, it ain't the same and I'm cleaning the egg off my face./w3tcompact/icons/blush.gif This morning I went out to my tractor and did a little experimentation after reading my repair manual. Here is what I found:
1. With the engine off (before starting) and the PTO disengaged or engaged, I could not turn the PTO shaft by hand.
2. With the engine running and the PTO disengaged, I could not turn the PTO shaft by hand.
3. With the engine running and the PTO engaged and spinning, I turned the engine off and quickly tried to turn the PTO. It turned easily for about 10 seconds and then suddenly became firm, then difficult, then impossible to turn.
My conclusion is that since it takes hydraulic pressure to release the PTO clutch/brake, there was sufficient pressure remaining to hold the brake off for a few seconds when I killed the engine. This might be just enough time to jog the shaft and line up the spline-gear teeth. Of course, it's also kinda funny to think of all of us shutting off our tractors and making a mad dash back to align our splines./w3tcompact/icons/smile.gif/w3tcompact/icons/smile.gif That seems to be the only choice we have without adding the old (keep rotating forever) PTO overrun clutches./w3tcompact/icons/crazy.gif/w3tcompact/icons/frown.gif
