</font><font color="blue" class="small">( The black collar on the shaft won't turn either way, left or right or back and forth. When I line up the splines, it will go on about a 1/2 inch onto the pto shaft before a raised "bump" in one of the groove's of the drive shaft stops it from going on any further. )</font>
I have to agree with the others then, you have the type that pulls back. Get a good grip on the shaft behind the collar with one hand, and use the other hand to pull it back. Hold the shaft up to the PTO and align it, push it on all the way and let go of the collar. Then pull back to lock in place. I hope this works without your having to go to the dealer. John
