Zusammenfassung:PURPOSE:To improve workability with the lowering of slope-ascending force or braking force eliminated even the slipping rotation part of wheels occurs by separately providing a hydraulic pump for driving a front wheel hydraulic motor and that for a rear wheel one. CONSTITUTION:In a totally hydraulic drive type lawn mower composed by mounting a cutting unit on a body lower part between front wheels T1 and rear wheels T2, individual wheels T1 and T2 are driven with hydraulic motors M1 and M2. In this case, a pump unit PU rotated by a vehicle-mounted engine E is composed by directly connecting each shaft of front and rear wheel hydraulic pumps P1 and P2, and each of hydraulic motors M1 and M2 is separately driven by each of the hydraulic pumps P1 and P2. Moreover a direction control valve 2, for switching four-wheel driving and two-wheel driving by switching the front wheel hydraulic pump P1 to for rear wheel driving, is provided on a hydraulic pipe line.
