Shigemi Hidaka

A mobile cultural machine including right and left traction members, a transmission, and a main speed change device operable to transmit, at any speed ratio, a driving force from an engine through the transmission to the traction members so that they are driven at any traveling speed. A steerage and a steering devise operate cause the steerage to differentiate the traveling speeds between traction members. The traveling speeds are reduced in response to the extent to which the steering device is operated, so that a machine running straight may smoothly be controlled to enter a spinning turn at the end of a row.
