Abstract:
A work vehicle includes a plurality of traveling devices driven for traveling, a plurality of articulated link mechanisms having a plurality of links pivotally coupled to each other to provide two or more joints and configured to independently support the traveling devices to a vehicle body with allowing lifting/lowering of the traveling devices independently relative to the vehicle body, and a plurality of hydraulic cylinders capable of changing respective postures of the plurality of links included in the articulated link mechanisms. A first link located at a position nearest the vehicle body is supported to be pivotable about a body side coupling portion. A first hydraulic cylinder for operating the first link has its cylinder tube side pivotally coupled to a coupled portion on the side of the vehicle body and has its piston rod side pivotally coupled to a coupled portion on the side of the first link.
