Ford 4000 pto slipping

[Larry Cobb]

I recently purchased a 1964 Ford 4000 tractor with a Slecto-O-Speed transmission
The pto tends to slip under heavy load such as my roto tiller
Is there any adjustment to the pto
Any input whould be appreciated

Select-o-speeds use a hydraulic clutch for the pto. If your pto slows or stops under heavy load, the cluch is probably worn.

I would check the adjustment on the cable first--

fordfarmer did you buy the 5000??

Cable adjustment could cause this symptom. It makes more sense to check that first than not.

Wrong oil in transmission will also make the clutch packs slip.
