Does anyone here have experience working on the bobcat versahandlers? I have a 2001 v518 with about 1,500 hours on it. The automatic park brake that engages when coming to a stop and disengages when the throttle is pressed isn't working properly. Randomly when I start the machine up sometimes the automatic park brake wont disengage when the throttle is pressed and the machine wont move. I am thinking it is a sensor/electrical issue. Has anyone else had these issues and if so what was the fix? The local bobcat dealer does not carry/service versahandlers. Also, randomly when the AC is turned on and the engine is under load it will surge and bog down/almost die.
