a solenoid including a solenoid housing defining a central bore, a conductive winding extending around the central bore, and an armature within the central bore;
a foot pedal pivotably mounted to a base and extending over the solenoid, the foot pedal including a foot pedal piston that is mechanically coupled to the solenoid armature; and
a hydraulic valve including a spool contained within a valve body having a pressure port, a work port, and a tank port, wherein the spool is operatively coupled to the armature, wherein the solenoid and the foot pedal are first and second valve operators for the hydraulic valve and independently cause the spool to move from a first position in which the work port is closed to the pressure port to a second position in which the work port is open to the pressure port.
