L3010 pto problem

[crazy pole hops farm]

My L3010 PTO slams in and out when I run the rototiller it feels like it has teeth missing on 1 of the gears I took it to the dealer and they put it on the dyno and that's what they think is wrong with it I took the tractor apart. I took out the mid case and looked in the rear end all the gear seem okay. Dose anyone have any ideas what else could be wrong with it. I just went through some of the older posts from a couple years ago an found what seems like my problem and they said it was just the cable needed to be adjusted. Could it be that simple.

The parts diagram shows 3 different types of PTO in that tractor. What type of transmission does your machine have? If it's not a hydrostatic do you have a live PTO?

Silly question but have you checked the PTO running different implements (brush hog etc..) to ensure the problem isn't in the tiller gearbox?

It's hydrostatic with 3 ranges I believe it's an HST

Yes I took it to the dealer and they put it on a dyno.

Ok at least it's a simple mechanical drive. Your PTO is actuated by a cam clutch that does double duty as the over running clutch. That would be the next most likely failure point. Look up your machine here, expand the clutch\transmission tree and go down towards the bottom to PTO Clutch [HST Type]. 050 and 070 is your over running clutch. It seems to be sandwiched between the transmission and the clutch. Follow the cable that actuates your PTO forward and see if you can find a way to inspect it. Examine the cable and linkage too, something could just be bent or out of adjustment preventing full engagement.

When I use the tiller I put on ear-muffs over the ear-plugs; we have lots of rocks and a rotovator banging the rocks sounds pretty bad, like 2 gearboxes spitting teeth. Unless you are tilling topsoil that has been screened.

I went to the Kubota website you sent me to but it won't let me pull up the diagram. I have the tractor apart and the overrun clutch looks okay it's located in the mid section between the rear end and the transmission I have the shop manual and I looked at the diagram I'm pretty sure that's what you're talking about.

Hummm. Strange it wouldn't let you open the diagrams, you clicked "open" next to the left of the tractor's name? Anyway I believe we're talking about the same part. If possible put it back together so you can still see it engage and see how far the linkage causes the clutch to engage. It's possible that's not allowing the clutch to fully engage.

I wonder if perhaps the main clutch's clamping force is low because it's worn out or out of adjustment. Do you notice any jerking in the travel speed when the PTO slips? Pulling and turning a rototiller is a very high constant load with large torque spikes as you hit rocks and such, it would certainly cause clutch slip before a lot of other loads.

Is it possible your tiller is too big for your machine? How big is it?

My tiller is 5 foot and the ground I was using in was very loose and it also did it when the dealer put it on the dyno to test the PTO. It slams In N Out like there's teeth missing on a large gear. Where is the clutch you're talking about located I haven't separated transmission from the block yet is it in that section
