PROBLEM TO BE SOLVED: To perform smooth and accurate acceleration control without causing hunting. SOLUTION: An acceleration control device for a combine harvester, which has an acceleration lever for increasing/decreasing an engine rotating speed to a target rotating speed, automatically controls the acceleration lever to control the engine rotating speed to a rated speed. When a threshing lever is geared for indicating threshing work, the acceleration lever is finely controlled with pulse output after the acceleration lever is positioned as rated with continuous output.
