We had this on our 760. Sounds like you have end float in the drive shaft couplers maybe the retaining bolts are worn thin or have worn grooves into the shaft ends. Worst part on ours was every time I got off to investigate the shaft had moved back to centre and was in register with the sensor. When you grease the inner coupling watch the drive shaft it will probably move about a half inch towards the outside of the machine under pressure of the grease. We had a badly worn outer coupling sleeve that was the real cause of trouble. Good harvesting Greyhawk (from Australia)
