ABSTRACT:
Controls for a hydraulically driven vehicle, so designed as to actuate a pilot change-over valve for directional control of travel for proper change-over by means of a lever for directional control of travel, to cause the hydraulic pressure fed by a hydraulic pressure source for a pilot to operate a valve for directional control of travel, and to actuate the valve for directional control of travel for proper change-over, whereby to cause a pair of motors for directional control of travel, arranged on the right and on the left of the vehicle, to either revolve in a forward or reverse direction, thus causing the vehicle to be put in forward movement or rearward movement, respectively where the controls for a hydraulically driven vehicle are so designed as to actuate a lever for directional control concurrently, thus enabling the vehicle to be put in either a right revolution or a left revolution.
