Abstract
A work vehicle includes a traveling vehicle, a backhoe having a base frame detachably connected to a rear portion of the traveling vehicle and an excavator detachably attached to a rear portion of the base frame. The base frame includes a pair of upper and lower base plates and a partitioning wall disposed at a fore-and-aft intermediate portion of the base plates for connecting the two base plates with each other and partitioning a space delimited between the plates relative to a fore and aft direction. A control box is mounted on the base frame. At least one swing cylinder is mounted to the base frame through the partitioning wall for pivoting the excavator. A control valve unit is attached to the partitioning wall downwardly of the control box for controlling a working fluid for driving the swing cylinder and the excavator. At least one swing hose is extended through the partitioning wall for hydraulically connecting the control valve unit to the swing cylinder.
