Friend of mine has a JD 6420S, its sat in my yard having had two mobile mechanics have a look - the second with laptop and JD software etc... neither can work out whats going on.
It has left had reverser, and I AutoQuad I think (Although bear with me as I know nothing about Green Tractors, far too expensive for me).
Anyway you start the tractor and all seems OK will move forward and backwards ok, BUT after about 2 mins will stop going backwards (then after a while wont go forwards). The only error code was Low Transmission speed, we did tilt the cab and change that sensor, BUT suspect that error is valid in that its erroring due to not moving....
Anyway the owner and another mechanic already put a new reverse solenoid on, and changed filters etc... and the 2nd Mechanic tested pressures on the gearbox and all seems OK, he also said you can watch all the pressures ramping up correctly but then it just doesn't move....?
The really odd thing is that you turn the tractor off and back on and then it moves forwards and back instantly OK?
Anyone else had this issue?
