<Inclination adjustment of aircraft frame>
The tilt in the front-rear direction of the body frame 1 is adjusted by driving a pitching cylinder provided between the body frame 1 and the traveling device 2, and the tilt in the left-right direction of the body frame 1 is adjusted between the body frame 1 and the traveling device 2. It is adjusted by driving a pair of left and right rolling cylinders provided between them.

  When the rear part of the body frame 1 is lowered and the front part is raised, the pitching cylinder is set after the difference between the height of the left part and the right part of the fuselage frame 1 is not more than a predetermined value by the pair of left and right rolling cylinders. Drive. Thereby, especially when a large amount of grain is stored in the Glen tank 7, the front side of the aircraft is prevented from rising while the Glen tank 7 side of the aircraft is lowered, and the operator feels uncomfortable when operating. Can be reduced.

<Inclination adjustment of aircraft frame>
The output rotation speed of the engine E is the maximum output rotation speed when the grain sensor provided in the Glen tank 7 detects that the grain has reached 50% or more of the storage capacity of the Glen tank 7. To the rated output speed. Thereby, the torque shortage of the engine E accompanying the increased weight of the grain stored in the Glen tank 7 can be avoided.

  Further, the output rotation speed of the engine E is detected by the speed sensor provided in the traveling device 2 and the speed of the traveling device 2 has reached a predetermined level or more, and the grain sensor provided in the Glen tank 7 When it is detected that the grain has reached 50% or more of the storage capacity of the Glen tank 7, the maximum output rotation speed is reduced to the rated output rotation speed. As a result, the traveling speed of the traveling device 2 is high, and the engine E torque shortage due to the increased weight of the grains stored in the Glen tank 7 can be avoided.
