PROBLEM TO BE SOLVED: To provide an operation device of a combine regarding to an operating lever essential for the traveling work operation of the combine, improving the operability of traveling work of the combine, and while suppressing its production cost, capable of securing controlling reliability. SOLUTION: This operation device of the combine is constituted by equipping at least one lever of a travel transmission lever (5c) capable of performing an inclined operation for traveling speed change and front and rear progression-switching operation of a machine body, and a swinging lever (3) capable of performing the inclined operation for the lifting up and down operation of a reaping part (A) and left and right swinging operation of a machine body, installing a multiple number of push button switches (SW) for alternative operations at its grip part on one of the levers, forming a multiple number of partial voltage resistance circuits (R) having different resistance values with each other for corresponding to these multiple number of push button switches, and also installing as mediating the above push button switches (SW) enabling the conduction of each of the partial voltage resistance circuits (R) with a common signal line (L).
