摘要： A tractor with a backhoe is disclosed. The backhoe is mounted to a rear portion of the tractor. The backhoe has a boom, an arm pivotally supported to a leading end of the boom, a bucket pivotally supported to a leading end of the arm, a boom cylinder for operating the boom, an arm cylinder for operating the arm and a bucket cylinder for operating the bucket. The tractor includes a frame attached to a rear portion of the tractor, a swing bracket supported to a rear portion of the frame to be pivotable about a vertical axis, a control valve unit having control valves for controlling the boom cylinder, the arm cylinder and the bucket cylinder and a hose unit for feeding pressure oil from the control valve unit to the boom cylinder, the arm cylinder and the bucket cylinder. The wing bracket includes a first opening open to the front side and a second opening open to the rear side. The control valve unit is disposed, in its plan view, on an extension line of the first opening and the second opening. The hose unit extends substantially linearly from the control valve unit through the first opening to the second opening.

摘要： A work vehicle includes a pair of, right and left booms detachably attached to a vehicle body, an implement attached to leading ends of the booms and a stand for supporting the booms with the implement being placed on a ground surface when the booms are detached from the vehicle body. The stand includes a pair of, right and left stand members provided in correspondence with the right and left booms and a stand connecting member for interconnecting the stand members. Each stand member is attached to the boom corresponding thereto in such a manner that the stand is movable between a use position in which each stand member projects downwardly from the boom for supporting the boom and a non-use position in which each stand member extends along the boom.
摘要翻译：工作车辆包括一对可拆卸地附接到车身上的左右起重臂，附接到起重臂的前端的工具和用于支撑悬臂的支架，当工具被拆卸时，工具被放置在地面上车体。该支架包括一对左右支架和一对左右支架，以及用于互连支架部件的支架连接部件。每个支架构件以这样的方式附接到与其对应的起重臂，使得支架可在使用位置之间移动，其中每个支架构件从用于支撑悬臂的起重臂向下突出的使用位置和每个支架构件沿其延伸的不使用位置繁荣。
