Having an issue with the park brake. When driving the tractor, it will randomly pop out of gear and the park brake light will come on as well as the 4WD light. I can stop, put the park brake lever on, on the left hand reverser and sometimes it will come off and sometimes it won't and I have to override the park brake with the OK button on the dash. The brakes on the tractor seem squashy to me. It doesn't throw any codes either. Could anyone help me out on this issue before I call the dealer for the third time?
