PTO Shaft Keeps Falling Off

How about the shroud on the shaft? IS it a little too long, and holding up on the mower gear box?

B7510,

</font><font color="blue" class="small">( I swapped the shaft end for end and it is not the shaft. Either end locks to the tractor spline just fine and neither end will lock to the mower spline. )</font>

Have you tried wire brushing the stub shaft on the mower? I'm thinking either a little bit of dirt or paint starting to bubble.

I have a landpride rear mower and had the same problem when I first purchased it. I could not get the shaft to lock onto my pto. After about twenty minutes I discovered that the bearings in the shaft where jammed into position. I released the collar and with the plastic head of a screw driver popped the bearings loose. After that it clicked onto the pto and has been working perfectly since. I'm not sure if you have the same problem, but it may be as simple as that.

Hope things start working.

Could it be something as simple as a locking c-clip not letting it slide back enough to seat? I had to finagle my KK pto shaft onto the gearbox and wiggle and cuss at it a bit to get the c-clip in the groove it rode in..

I bought a slip clutch that wouldn't lock in place. It needed to have 1/8' removed (machine shop, $15) from the end that was on the tractor to allow the slip clutch to go on far enough to lock.

I had a defective PTO U joint on my BX2000 60 in. MMM. The firs time it came off it ruptured the hydro filter and bent one of the parking brake linkage. Kubota (the dealer) instisted that I had not installed the shaft properly. At first I thought that they were right but I found that if I wiggled the shaft and pulled on it, it would come off. The problem was in the locking mech. on the PTO shaft. As I recall, there were three balls that locked into the grove on the shaft. One of the balls was hung-up and would not snap into the grove. I tried to lube it but it still would not lock properly. Kubota finally replaced the U joint and it resolved the problem.

Do you have any info on the final resolution to this problem? I just bought the exact same mower and am having the exact same problem and am curious as to how you resolved it.

Thanks,
