Abstract:
Disclosed is an agricultural work vehicle with a simple configuration and having an automatic lifting/lowering control of a work device during swiveling. When the steering wheel (7) is operated at or above a prescribed operation amount, a side clutch operating mechanism (45) disconnects a side clutch. Clutch sensors (49L, 49R) are capable of detecting the side clutch operation state. The control unit controls driving a lift cylinder for driving the lifting/lowering of a planting unit. A planting clutch is capable of switching between transmitting and not transmitting the driving force to the planting unit. Further, during operation of the planting unit, the aforementioned control unit is capable of detecting release of the planting clutch, release of the side clutch, and reverse operations as triggers for starting automatic lifting/lowering control during swiveling. Furthermore, the aforementioned control unit, upon detecting any one of the start triggers, raises the planting unit and then, upon detecting the engagement of the aforementioned side clutch, lowers the planting unit.
