Abstract

PURPOSE:To give no excessive force to a working machine, by controlling so that turning center of front wheel and rear wheel in turning is always situated on an axis crossing at right angle to turning direction of a tractor through the working machine mounted to rear of the tractor in planer sight. CONSTITUTION:A rotary tilling machine 3 is mounted to link device provided to rear of a tractor and a hiller 4 is attached to rear of the rotary tilling machine 3 and datum point A is appointed. Relationship with steering angle alphaof front wheel and steering angle beta of rear wheel is controlled so that turning center P of front wheel 5 and rear wheel 20 of the tractor in turning is always situated through the datum point A on the axis crossing at right angle to turning direction of the tractor and the hiller is followed to the tractor without sideslipping.
