AGRICULTURAL VEHICLE

摘要

An agricultural work vehicle is disclosed. The agricultural work vehicle according to the present invention is operated by a hydraulic stepless transmitter (HST) drive system. Oil that is stored in an oil tank passes through a gear pump, an oil cooler, an oil filter, and the HST one after another to form a circulation type hydraulic circuit for returning to the oil tank. An accumulator is mounted in the oil filter in parallel in order to compensate pressure drop in the oil and an insufficient flow rate in the hydraulic circuit.
