A1

A combine for driving a traveling section (2) by transmitting the power of an engine (21) to a transmission case (22) provided with a traveling speed change mechanism (40), characterized in that the power of the engine (21) is transmitted to a counter case (25) in order to drive a threshing section (4) by a substantially constant rotational output and the speed change output from the traveling speed change mechanism (40) is transmitted to the counter case (25) in order to drive a reaping section (7) at a speed synchronous with the vehicle speed, and the counter case (25) is arranged such that the reaping section (7) is driven at a substantially constant speed by a substantially constant rotational output from the counter case (25). The counter case (25) for driving the threshing section (4) at a constant speed can also drive the reaping section (7) at a speed synchronous with the vehicle speed or at a substantially constant speed, and the reaping section (7) can be driven at a constant speed utilizing a part of the driving system of the threshing section (4), resulting in simplification of driving structure of the reaping section (7), or the like and reduction of transmission loss.
