Can't Remove MMM PTO Shaft

Can\'t Remove MMM PTO Shaft

I have a BX2200 with a 60" MMM. I am having a problem removing the MMM PTO shaft from the mower. The release collar appears to slide back OK, but the ball bearings do not seem to be loosening enough allow the shaft to slide free of the spline (it moves only 1/4", then jams). I've lubed it, twisted, pulled, pryed and cursed it with no luck.

Some history... The shaft came loose once this summer when the dealer failed to put it on all the way after service. I had the RPMs all the way down when I engaged the PTO and stopped it pretty quick when I heard the noise. The shaft took a few hits on the underside of the mower and was a little banged-up but did appeared not to be damaged. It went back on OK at the time and I didn't try to get it off until now.

I now have the MMM off the tractor so I have good access to the underside. I slid the shaft off at the coupling, but still have the collar, U-joint, and a 6" piece of shaft attached to the PTO. I'll go ahead and buy a replacement (anyone have a good source?) but I need to get this off first!

Any suggestions?

Thanks in advance for the help.

I assume you have removed the mower by lifting the front end, pulling the pins and sliding it forward until the shaft separates.
I would pull the retaining ring forward, spray the shaft with penetrating oil and let it set. Then tap on the back of the shaft while holding the ring forward. If one or more of the bearings has set, that would be the best way to free it up.

i have an bx1800 mine has been stubborn when it came time to take it off after a season of cutting. i use a prybar and a rubber hammer. i apply pressure with the prybar trying to slide the shaft of while tapping on the coupler with the rubber hammer.

it should come right off. i always lube both sides before i reinstall the shaft

Take it back to the selling dealer and have them replace it under the 1 year warranty. If the selling dealer won't replace it, then order a new one from www.tractorsmart.com. The reason for not purchasing it from the selling dealer is why reward him for not taking care of a warranty problem that he won't resolve for you.

Problem solved.

I just got a better angle and used a pry bar to slide it off the spline with the collar fully retracted. It took a lot of leverage to come free. It shouldn't be this difficult! I lubed it and tried to put it back on and had the same problem. One of the ball bearings won't retract fully.

Well... I guess I have all winter to figure it out.

Thanks to everyone for your suggestions. This is a great web site and discussion forum!

I had the opposite problem with mine. One of the ball bearings would not extend all of the way and the shaft would come off while you were mowing. At first the dealer and Kubota insisted that I was not pushing the shaft on all of the way. Eventually they conceded that the collar was defective. If you examined it closely you could see that one of the ball bearings was not popping out far enough to lock onto the PTO shaft.
