Ah yes, the price of ignorance is the cost of education.... As others have said dremel tool and stone to remove the burr and it should slide off. If you have a flex shaft dremel or similar, they have a smaller body that won't get in the way, as much...

I posted a similar problem with the PTO shaft binding on a 15 ft batwing a few weeks ago... My idea was the front shaft is TOO SHORT and should be a couple feet LONGER and the TOWER mount back further on the hitch.. Then when you turn a corner, the ANGLE in the shaft would be much reduced..... Apparently it is not a big problem if you DONT TURN TOO SHARP..... I rebuilt the batwing original tower so it pivots easier and rebuilt the SHORT front pto shaft ( new u-joint) ..........
your photo.....mine looks similar. |

Im working on a 15 ft Batwing right now... Correct me if i am wrong, but there is a TOWER on the mower hitch at the BACK END of the drive shaft... There is a support bearing that hangs inside that tower... The "front pto shaft) is maybe 24 inches long and SOLID.. it does not slide and change length... BEHIND the tower there is a 5 ft long drive shaft with a square drive inside a tube... that is what gives you the LENGTH NEEDED.. When you turn a corner, the TOWER is suppose to PIVOT forward or back a couple inches and make sure what happened, does not happen..
I dont think you shaft is TOO LONG... I think you turned TOO TIGHT for this design of pto shaft / hitch ... You need to take a small air or electric die grinder and reach in and grind off the burrs or any high spots on the end of the shaft... Go slow and take off plenty.. A little undersize at the edge will not hurt... Eventually the shaft will then slide off.

540 RPM is 14" and 16" is for 1000 RPM I believe.

Aren't 540's supposed to be 16 inches from end of shaft to center of drawbar hole?

Neighbor did pretty much same thing, we dropped the bush hog and pulled the driveshaft apart,we pulled the plastic guard off the half still on the tractor, then we put a breaker bar on the back of the pto shaft,and lifted up on the drive shaft, pulled it right off there.

Maybe remove the 'cross' of that Ujoint first, so you get GOOD access to the end of the PTO shaft, then deburr and see if the yoke moves. You may be able to put a 'gear puller' on the stuck yoke and pull it off. If possible PUSH the yoke closer to the tractor to expose more of the PTO shaft for deburring operations.

You might have raised a bit of a burr or distortion where it was striking the end of the shaft, I think I’d start by dressing that on both sides with a file or small grinder and then see if shaft will slide off.

While using my CA and Woods brush hog, I turned as sharp as I desired. Initially I didn’t pay attention to the drive line chatter and vibration that occurred during the sharp turns. But the damage was already done. The binding of the Woods drive shaft forced the yoke forward of the tractor’s pto shaft detent. Now I can’t remove the Wood’s shaft. The Woods shaft can slide forward until it contacts the tractor and can be pulled rearward to what I believe is almost the intended operating position.
What is the best approach to removing the mower’s shaft from the tractor? |
