Abstract:
A steering operation device and a method for controlling the device, where steering operation does not require an operator to be skilled, wheels of a towed agricultural working machine do not need to be steered, and the device is simple in structure and low in costs, and can also be simply attached to existing towed agricultural working machines. An steering angle of front wheels (8) of a tractor and a towing angle of an agricultural working machine are detected and controlled, so that a tow center point (P) of the tractor is moved in left and right directions such that the traveling locus of a rear axle center point (T) of the tractor and that of an axle center point (S) of the agricultural working machine are matched. The movement of the tow center point (P) is performed by a steering operation device (11) constituted of a screw and ball nut that is driven by a hydraulic motor.
