I have a kubota kx121-3 that will not come out of hi range on the tracks. The green rabbit button stays lit green and when you push the button it keeps like normal but nothing happens and the light stays lit. What can I check? I do not have a manual for this machine.

Do you hear a beep noise when you push the button? Mine was sticking in high but would go back to normal if you cycle the key. Sprayed some silicone in the switch and it worked better
Figure it out? Sounds electrical to me. I have a series 3 manual
