the operation of the propel systemThe propel system contains an electrical portion, a hydraulic portion, and a mechanical portion. The electrical portion consists of an electronic control module (ECM), input devices, and output devices. The hydraulic portion consists of a closed circuit, hydrostatic drive loop with a single pump and two motors. The mechanical portion consists of a planetary gear reducer for each drum.The propel hydraulic system shares a common hydraulic tank with the steering hydraulic system and the vibratory hydraulic system. The steering pump supplies charge oil to the propel hydraulic system. The front propel motor is a fixed displacement motor. The rear propel motor provides two speed ranges. Each gear reducer is equipped with spring-applied, hydraulically released parking brakes. The brakes are hydraulically released. Also, the parking
