<p>The wheeled working machine has a drive motor (2) for driving wheels through a hydrostatic transmission (21). The hydrostatic transmission has a powered pump (28) which pumps a hydraulic medium from a suction side (68) to a pressure side (69), and supplies hydraulic medium to hydrostatic motors (41,42) through a pressure line (43). A brake valve (59) is arranged at out-flowing side (70) of hydrostatic motors. The brake valve is opened automatically when pressure at out-flowing side of hydrostatic motors is increased.</p> |
