Was using brush cutter with slip clutch. Hit a small tree stump and carried on for about 30 feet and cutter stopped spinning. Check PTO shaft on tractor and it spins freely. No grinding or metal on metal when I spin but I do hear a slight noise from a bearing. Any thoughts about issue before I get too excited?

Could be anything in the pto driveline , from something failing at the rear -- all the way to the engine coupler
At this point pulling the pto housing would be the first step

Pictures of the carnage for the forum would be helpful , in case someone has this same problem

I would look for a shear pin (bolt) where the PTO shaft connects to the gear box input shaft on the brush cutter.

It probably sheared due to the slip clutch being locked up and not slipping. When was the last time you slipped the slip clutch in the drive line?

I removed the brush cutter. Tractor end of the PTO Shaft spins freely. I did adjust the slip clutch in the spring but probably should check it more often. Thanks.

Unfortunately the tractor is coming up on 3 years old ... so I will probably get Kubota to take a look ... I have so many things to sort out this time of year that if I start working on it will take months .... months I do not have. Painful $$$s. I will make sure the techs take pictures of the damage and will send out.

If the PPTO shaft spins freely you broke something in the drive line. Should be almost trivial and 10 minutes to find what.

I guess from reading closely that you are saying the PTO shaft that exits the tractor will rotate freely in both directions so something inside the tractor is broken.

That is somewhat surprising considering the brush cutter blades should have folded back, or the slip clutch should have slipped but neither safety worked.

I know nothing about your tractor but would assume that there is a shaft broken inside the tractor but it could be a PTO clutch problem.

Good luck at the dealer and if you have it financed then you may have KTAC insurance to cover the damage.

If the clutch is stuck due to rust or other reasons, it may not slip when needed, which can cause overloading and stop the rotation.

If your steering works, the failure is from the hydraulic PTO clutch or rearward.

The English language is so easily confused. Read what he wrote again.

I removed the brush cutter. Tractor end of the PTO Shaft spins freely.

He is talking about the PTO shaft on the implement not the output shaft on the tractor.
