ABSTRACT:
A crawler tracked vehicle of the type including right and left crawler tracks is provided and includes a prime mover drivingly connected to the crawler tracks through a differential, or the equivalent, as well as separate clutch and brake mechanisms interposed in the drive train for the tracks intermediate the differential and the tracks. A single oscillatable control is provided as well as a set of fluid pressure actuators for the clutch and brake mechanisms. A source of fluid under pressure is also provided and a set of fluid flow conduits communicate the source of fluid pressure with each of the actuators, independently, with a set of valves being provided and operatively associated with the fluid flow conduits for selectively controlling the flow of fluid therethrough to the corresponding actuators. The single oscillatable control and the set of valves include coacting structure for opening and closing the valves in predetermined opening and closing sequence in response to oscillation of the oscillatable control. Still further, a second set of fluid flow conduits is provided for communicating the source of fluid pressure with each of the actuators, independently, and a second set of valves is included in the second set of fluid flow conduits for selectively controlling the flow of fluid therethrough to the corresponding actuators. The single oscillatable control also coacts with the second set of valves for opening and closing the second set of valves in a second predetermined sequence different from the first mentioned sequence, in response to oscillation of the oscillatable control, a control valve being provided for selectively communicating the source of fluid under pressure with the first and second mentioned sets of fluid conduits.
