[TenTec] Argosy II problem

[Mike Bryce]

I remember reading that article, but let me toss this out

those bad jumpy PTOs left the factory with a defect,

I don’t feel after 34 years of operation, that factory defect would raise its ugly head.

An old mod was to use a safety pin to ground the PTO shaft. Putting the shaft at ground potential. There is enough ‘spring’ in the safety pin to apply pressure to the shaft. It fastens to the chassis with one of the PTO mounting screws.
