INDIVIDUAL CIRCUIT DESCRIPTION
PARK BRAKE
Power for the 2G5694 Park Brake Solenoid Valve is through the 60 amp circuit
breaker to the solenoid valve. The solenoid valve is normally closed.
The solenoid valve is activated (open) anytime the disconnect switch is closed.
When the disconnect switch is open the valve closes. In the closed condition, it
prevents the release of the parking brake. It also prevents the retraction of the
centershift lockpin. This prevents dropping the blade if it was not on the ground when
the engine was stopped.
