Hey everybody, man this seems like a cool website, its like a mechanic's facebook! Anyways one of my D6 Dozers has a problem. I bet it's something small and easy but i can't figure it out because I don't have the technical manual on hand. The hydraulic lock-out switch will not disengage and i cant figure out why. I checked all fuses and reset my circuit breakers. I thought it may be the pressure indicator for the seat but its not that either. Any advice is much appreciated.
