PROBLEM TO BE SOLVED: To provide a new structure capable of remotely controlling a reversing action of a ridge forming part from a seat of a tractor. SOLUTION: A ridge forming machine has a mount frame, a support frame, and the ridge forming part, wherein the mount frame has a relay transmission part transmitted from the tractor, the support frame is equipped with a turning means horizontally turning on a rotary shaft vertically positioned at the rear part of the mount frame, the ridge forming part is positioned on the opposite side to the support frame, so that the turning means is electrically driven to be remotely controllable from the seat of the tractor. Further, the ridge forming part is automatically controlled to be located on a desirable position by detecting each of a forward working position and a backward working position round the rotary shaft as a turning angle by using a potentiometer, and then converting the angle into an electric voltage. Therefore, a control set position of the ridge forming part is electrically controlled by a value of the electric voltage regardless of unevenness of the turning means caused by machining accuracy, nor a backlash of parts thereof, and the machine is compactly produced.
