摘要： PROBLEM TO BE SOLVED: To maintain the rotational frequency so as to be constant regardless of the change in the load on the engine of a combine harvester, and further, when the set rotational frequency is changed to a lower value, to enable the operation at the time when the kinds and/or conditions of crops are changed, to be carried out easily by enlarging the air volume for separation in a threshing device in inverse proportion. SOLUTION: A power from an engine 51 regulated so that the rotational frequency is controlled by an electronic governor 54 is transmitted to right and left pairs of traveling devices and threshing devices in parallel. When the rotational frequency of the engine is changed to an arbitrary value by a rotational frequency setter 59, the electronic governor can be set to be in a constant rotational frequency mode by turning a constant rotational frequency-controlling switch 60 on so as to keep the set value constant. When the rotational frequency of the engine is set to a low value, a speed-changing structure is operated so that the open area of an inlet port to a winnower fan may be enlarged by the operation of an actuator 41, and the rotational speed of the winnower fan may be enlarged by the operation of an electrically driven motor 49.

摘要： PROBLEM TO BE SOLVED: To facilitate the changing of inclination and an absolute horizontal posture by the manual operation of an operator during agricultural work by presetting only a car height. SOLUTION: A set car height value is stored beforehand in a car height setter (S1) and, when an operation lever is operated (S2: yes), left and right inclining posture control values at the end of this operation are stored in an inclined value storing means, inclining posture control is executed according to the left and right inclining posture control values stored at the end of the operation, and a car height is changed (S3). When a horizontal setting switch is turned ON while the operation lever is not operated (S2: no, S4: ON), horizontal posture control is executed for setting a traveling machine to be horizontal left and right (S5), and when the horizontal setting switch is OFF (S4: OFF), control is executed to hold the inclining posture at the end time of the operation of the operation lever, and priority is placed on the control of a horizontal or inclining posture (S5, S6) rather than on car height control (S8).
