PROBLEM TO BE SOLVED: To obtain the subject equipment enabling the thrusting state of a reaping part placed in the front part of a combine harvester into the field to be prevented and also overruns in cutting height of grain culm and threshing depth of reaped grain culms fed into a thresher be prevented by installing a specific controller. SOLUTION: When a combine harvester is equipped with a main speed change lever 53 changing the running speed of a running gear 2 by switching the operational position of the lever itself, a speed sensor 21a detecting the running speed, an inclination conditioner 5 adjusting the lopsidedness of a traveling truck 3, left and right inclination sensors 42a and 42b detecting the lopsidedness of the traveling truck and a thresher 9 threshing grain culms, a controller 36 is installed to halt the rotational control toward speed increase even when the travel speed of the running gear 2 is switched toward speed increase by the operation of the main speed change lever 53 under the regulation of a transverse tilt of the traveling truck 3.
