ABSTRACT:
A fluid control circuit for controlling the disengagement of first and second drive mechanisms and the engagement of first and second brake mechanisms for a track-type vehicle has a fluid pump and first and second foot operated fluid control valves in fluid communication with the pump. Shifting of either control valve individually disengages the associated drive mechanism and engages the associated brake mechanism. Shifting of both control valves concurrently, engages both first and second brake mechanisms while the first and second drive mechanisms remain engaged. Conventional track-type vehicles use two pedals to sequentially control the disengagement of first and second drive mechanisms and the engagement of associated brake mechanisms. A third pedal controls engagement of both brake mechanisms without disengaging the drive mechanisms. The three pedals complicate the control system and create a crowded operator's station. The subject control circuit uses only two pedals to operate two control valves to disengage the drive components and engage the brakes.
