Hi,
I am new in tractors and I have an orchard tractor M5101N (used 2200hrs).
Error 21 popped up and the manual says “Range gear shift (Hi) switch trouble”.
It happens only when I put the 6th gear for travelling home. I switch off the tractor and the error disappears. Until I put the 6th gear!
All day at work… no errors. Only when I travel! Also I don’t feel or hear anything wrong when the error appears. The tractor moves normally. I stop, switch ignition off, switch on, put 5th gear, and return home with no more errors.
Has anyone else the same problem? Please advise.

Check the wiring and switches located on the shifter cover. They are on the RH side of the transmission.
