Parking Brake Not Disengaging.

[B2Blain]

I am using a Bobcat for some work on my lot. It doesn't always happen. Usually turning it off or raising and lowering the armrest works. But there was an incident today when I had to go through several cycles of turning it off and on and raising and lowering the armrest. I didn't have a load in the bucket. Any thoughts on whether something is failing? Thanks!

Could be a problem with operator present system. Depending on model could be seat sensor or seat bar sensor. Could also be in the park lock. They are a double circuit solenoid with a lift and hold side. If the lift side gets weak it won’t always lift the lock pin
