PROBLEM TO BE SOLVED: To provide an agricultural work machine capable of accurately grasping tillage dept by a rotary tillage device and adjusting the tillage depth during operation of a tractor, by calibrating change amount of the tillage depth by the rotary tillage device with respect to control amount from the tractor, the change amount variable depending on a combination of the tractor and the rotary tillage device.SOLUTION: The agricultural work machine, which connects a rotary tillage device including a rotary tillage claw in a liftable/lowerable manner to a tractor through a link mechanism, includes: a lift angle sensor 28 detecting a rotation angle of a lift arm lifting/lowering the link mechanism; a storage unit 61 storing a correction coefficient for each rotary tillage device; a control unit 60 calculating a depth position of the rotary tillage claw based on the rotation angle and the correction coefficient; and a display unit 63 displaying at least the depth position of the rotary tillage claw. The control unit 60, after calibration with a grounding condition of the rotary tillage claw as the reference, calculates and displays on the display unit 63 the depth position of the rotary tillage claw. |
