Ok, I am new to the Cub Loboy 185 seen, but if the PTO spline is the same on the 154, 184 and 185, why not just pick an electric clutch on it and tact weld the two shafts together and eliminate the old style clutch altogether? :big give up:

Does anyone know if you can put a PTO in the rearend pig of a lowboy 185 like the ones in the red cub cadets have in there rearends?

Sure now you tell me, I just spent $200 for the kit... I had a lot of work cut out for me on this clutch. the short shaft had a crack in it, so i had to put it in my vise, weld it then use die cutting wheel to dress it clean. I am using a brass bushing inside the short shaft and on the long shaft instead of the set of pin bearings. Not sure how that will work out. seem to fit ok though. I also used emery clothe ribbon to clean the shaft really well where the cam and cam bearing will slide very freely. I think this is very important, this may be why people are getting PTO cluches buring up because they are not sliding appart freely and releasing the clutches completely thus overheating when not being used. Also if not shimmed just right it will wear out quicky.
This advise comes from years of experience as a mechanic, but not a tractor mechanic... so it is worth what you are paying for it.

Additionally I looked at the PTO clutch picture that is assemble on this website and i think it may be put together incorrectly. The cams are turned around backward. You want to be able to put the clutch pack as far into the clutch bell as possible, so make sure the clutch cam ingauging arms are facing in such a way as will allow that.

My 154 LoBoy was mowing fine, when the pto clutch suddenly disengaged, pulling the lever down into the disengaged position. When I tried to re-engage it, it engaged for a few seconds, then violently disengaged again, taking the knob right out of my hand. I subsequently installed a new clutch pack, but when I tried to engage the pto clutch, it did the same thing it did before, taking the lever right out of my hand. It seems to snap firmly in place when I engage it, it just won't stay that way. It does this with or without the drive pulley and belt for the mower in place. I need to mow! Does anyone have any idea what I'm not seeing here?

Check the large cam bearings. If one is binding it will cause the cam to rotate and disengage as you describe.

It was one of the two ball-bearings in the rotary PTO clutch. It's all fixed, but in the meantime I bought a Toro 62" commercial zero-turn mower. I'm not sure yet what I'm going to do with the old Cub Lo-boy.
