<p>A traveling control device for a wheeled work vehicle includes: a hydraulic pump (130); a traveling motor (115); a work device actuator (116, 117); a traveling directional control valve (145) and a work device directional control valve (146, 147), with the traveling directional control valve (145) and the work device directional control valve (146, 147) disposed on a center bypass line at the hydraulic pump (130); a flow control valve (161); a traveling operation member (155); a work operation member (156, 157); a traveling operation quantity detection means (171); a work operation quantity detection means (172); an output pressure detection means (173); and a valve control means (120). The valve control means (120) controls the flow rate of pressure oil delivered to the traveling motor (115) so as to deter bucking of the wheeled work vehicle if the wheeled work vehicle, currently in a traveling operation-only state in which the traveling operation member (155) is operated but the work operation member (156, 157) is not operated, shifts into a combination operation state in which the traveling operation member (155) is operated and the work operation member (156, 157) is also operated.</p> |
