i've had the above unit since new, at around 800hrs i started to find that tractor would only move at about 1/8 norm opp speed when pushing forward or reverse pedals. i could overcome this by cutting reves right down, drepressing pedal & building revs back to working level. JD dealer found it was a "computer calibration issue" & reset unit & all seems fine. Question has anyother JD 3120 owner experienced this?
