ABSTRACT:
A method and apparatus in which a laser controllable ditcher drawn by a tractor to which it is attached for forming ditches, furrows and the like incorporates a cutting disk which is adjustably inclined downwardly toward the rear of its direction of travel such that its under face forms an acute angle with the ground beneath so that its leading edge cuts into the ground. The disk is driven rotationally through a speed reducer by a driveshaft extending to the ditcher from the tractor. The disk has spaced cutters at its edge which dig into the soil and cause the soil to be lifted into the path of movement of paddles or scoops on the back side of the disk which in effect throw the soil particles a considerable distance to one side of the tractor path. The distance of throw is established by the depth of cut and is assisted by an adjustable inclination or lift of the upward moving side of the disk in rotation to produce the desired trajectory for throwing the soil a distance to one side such that upon subsequent passes of the ditcher the soil is not required to be picked up again and redistributed.
