Abstract:
A work vehicle includes a pair of booms, a link mechanism and a control unit. The booms are attached to a front part of a vehicle body in an upwardly and downwardly rotatable state. The link mechanism couples a working unit to tips of the booms. The link mechanism is configured to keep the working unit in a posture generally parallel to the ground without rotating the working unit with respect to the ground while the booms are elevated from a position where the working unit is disposed on the ground when the working unit is a fork. The control unit is configured to execute a tilt angle adjusting control for the working unit in accordance with variation in an angle of the booms while the booms are elevated when a tilt angle of the working unit is greater than or equal to a predetermined threshold.
