For the steering control system of combines, a driving feeling is produced via the steering wheel by using a forced differential system that drives the differential gear by force. This system has two hydrostatic transmissions for traveling and turning and can make various turning radii along the steering wheel angle by making differential revolution using a planetary gear drive. This paper describes some problems that occur when the forced differential system is used for crawler vehicle, such as combine.
