PROBLEM TO BE SOLVED: To provide a working vehicle equipped with a lifting link mechanism portion for lifting or lowering a top-pruning device for cutting the tip portions of crops in a posture approximately parallel to the ground, thereby improving the efficiency of top-pruning work. SOLUTION: The working vehicle is drivably attached with a working cutter for crop tip-cutting treatments to a lifting link mechanism portion which is disposed in the front portion of a travel vehicle and is lifted or lowered in a posture approximately parallel to the ground with a lifting cylinder. In the working vehicle, a chemical solution spray device composed of a spray boom lance having spray nozzles for spraying the chemical solution on the crops of a field is disposed behind the working cutter on the lifting link mechanism portion. In the working vehicle, the angles of the working cutter and the spray nozzles can be adjusted within an upward or downward rotation angle range on the basis of a horizontal base line.
