John Deere 320 Skid Steer Parking Brake Problems

[dawgfandanno]

I have a John Deere 320 skid steer. I switched machine off without engaging the parking brake, took off seatbelt and exited the machine. I re-entered, put on seatbelt and attempted to crank it. The seatbelt indicator functions properly. The instrument panel shows the indicator that machine's parking brake and boom lock is engaged even though the light behind the parking brake switch is not lit up. When I try to crank, no beep and no start. Battery has plenty of juice. The right pedal for rolling boom is free. The left pedal, for boom up/down, is locked leading me to believe the boom lock is preventing the park brake from being engaged to re-crank the machine. Any suggestions to cranking my loader would be greatly appreciated!

Not familiar with the 320 but on our 250 everything was grounded through the display when the display went it wouldn't unlock. Good luck
