Abstract
A drive control system of a crawler vehicle has a lever, a hydraulic distributor for feeding pressurized oil over a feed line to a hydraulic actuator. The hydraulic actuator can engage and release a central clutch. A cable has a first end fixed to a rod of the hydraulic actuator, and a second end connected to the hydraulic distributor. The cable activates and deactivates the hydraulic distributor, depending on the position of the rod. A main pulley is integral with the lever about which the cable is wound.
