Adjusting a PTO Slip Clutch

[@g.alistar7798]

Key point. Draw it tight by hand...then one and 1/2 turns. Each bolt....thanks!

Attach tiller on tractor, loosen up all the bolts and run tiller to conferm all the disks are spinning. Continue with adjustment. Do every year before use.

I just bought a new 6' King Kutter. Factory set pto clutch bolts were 3 1/2 turns in. I turned all nuts loose and slipped the clutch. I started of with 1 1/2 turns in. Ran the tiller one time across the field. Marks showed the clutch slipped and clutch was starting to get hot. Turned nuts in another 1/2 turn. Another pass across field and marks showed it had slipped. Turned nuts another 1/2 turn. Another pass across field showed it still slipped. Clutch was not getting hot but I had no way to tell if clutch slipped 1/4 turn or several turns. I may go in one more 1/2 turn to see if it stops moving. 1/2 turn after that and I am back to the way it came from the factory, which was really tight . The springs were mashed almost together.

@@fredricksiegmund627 this all sounds very frustrating, sorry you are experiencing it. I almost wonder if the springs could lose their tension.

Any ideas on how to TEST it manually? My instruction say to spin it 2 turns. Maybe I'll lock in the tines and try to spin the PTO..

[@YoungbloodFamilyFarm]

Hmm, I believe the instructions say once a year to loosen bolts and let the clutch spin to prevent rust locking it up, I would make sure you don’t damage your tractor clutch or pro, but decent idea

Mine has less than 50 hours on it,brush cutter not tiller. I also don't think the dealer did a "run in" on the clutch, just tried and appears one plate slipped but not the other one. I'm thinking about contacting another kubota dealer. Any advice would be greatly appreciated!

Best of luck, I find I have the best luck when I visit these place in person instead of phone calls

[@iSAAConrad]

There’s no way one could spin and not the other if you see how it works. The clutches don’t necessarily have to turn relative to the drive side or the driven side.

Have you ever had any issues with these getting out of center?

[@YoungbloodFamilyFarm]

I have not, are you referring to the clutch disc?

[@jeffstrains4014]

@@YoungbloodFamilyFarm Yeah I am thinking the hub might be worn or bent, going to take apart clean put back together burn in see if that helps. bought an older brush cutter. the disk are not centered with the hub so it shakes, then causes its self to come loose from the gear box making a wobble. In respect to what it is bought at farm auction really cheap, its a 7ft super heavy duty cutter that was used with a 130hp john deer tractor SO its possible it could have hit something not slipped and warped where it connects to gear box. The splines do not appear to be worn.

Thank you!

[@YoungbloodFamilyFarm]

Glad this helped

[@mervynshute880]

if it stopped the tractor. that means the clutch was not slipping

[@YoungbloodFamilyFarm]

Absolutely, this is what brought on this video and the research to adjust,
