Abstract: A leader angle control device comprises two inclinometers for measuring inclination of a leader in two directions, an arithmetic unit for calculating the length of two backstays which support the leader based on the detected inclination of the leader and a control unit for controlling backstay cylinder driving oil.In one embodiment of the leader angle control device, the leader angle is controlled manually to a certain extent before automatic control takes place, whereby the acceleration applied to the leader at the time of shift to automatic control is kept small and then gradually increases, thus enabling smooth control of the inclination of the leader.
