My wife was doing some brush hog work yesterday and when she was done for the day she said that in the areas where the grass was thicker the mower would stop. First thing I told her was to only cut half a row in those areas but I tightened the clutch on the mower a bit also. Today I was doing some of the mowing and the mower did the same thing. However, after looking into what was happening I found that the PTO was actually stopping. It has an independent PTO and I bought this brush hog years ago because my wife went through shear bolts by the box on my original mower with no clutch so pto certainly did not stop when the going got tough then. I thing that is really puzzling is that there is no bad noises or smells that would indicate anything is wrong. The PTO just quits turning. I've had 6 Kubotas and never experienced this before. Any one have any thoughts on what is happening. Thank you

I would look for a pto clutch test port. How long since hyd filters were changed? Do other hyd functions operate as designed?
Sounds expensive to me! If the PTO slips, even for just a little while, the clutch discs will be warped and ruined.

Please clarify what you’re saying about “pto was actually stopping”.
Did the short shaft out of the tractor and the first part of the pto shaft stop turning?
Did the rear end of the pto shaft stop turning and the front part at the tractor keep turning?
Trying to see if tractor problem (sounds like what you mean) or pto slip clutch problem (what you thought you resolved by tightening it up).

All new filters and fluid change less then 20hrs ago. PTO stops..... It has nothing to do with the clutch on the drive line to the mower. All other hydrolics work fine as does the transmission clutch. When PTO stops turning there is no squeals, growns, bangs, or shattering. It just stops till mower is lifted then starts turning again . Nor is there "any" smell like a hot burning clutch.
Russells’ post brings up a matter I’ve seen occur several times/places in these forums….. identification or definition of ”PTO”.
I believe the confusion can be clarified by recognition/definition of PTO as “Power Take-Off”…..which is the splined-shaft that exits the rear axle/transmission of the tractor.
The “PTO” …. is NOT… the Drive-Line that connects the tractor to the implement (shredder in this thread….. “Bush-Hog” is a common phrase but is actually a brand-name of a shredder or rotary-cutter implement…. sort of like saying “Xerox copy”…when meaning “photocopy”.
Anyway, the PTO-shaft is the short shaft exiting the rear of the tractor to which is connected any PTO-Driven device…such as a drive-line (usually equipped with Universal-joints)….that transmits the PTO power to the implement.
In THIS thread, I understood that the PTO-shaft of the tractor stopped turning. If so, it can be an internal clutch, gear-set, or other tractor-internal problem.
If the PTO is turning….but the driveline does not turn…it might be a U-joint collar shear-pin/bolt that has failed. Look to see if the first U-joint is spinning… if so then look to see if the drive-shaft is spinning…then the aft U-joint….. lastly the driveline clutch.
