ABSTRACT:
A rotary ditcher has a flywheel type rotor carrying impeller blades that pick up and throw soil to the side of the rotor as the rotor is advanced into a body of soil in the direction of its axis of rotation. In advance of the rotor are two ripper blades that loosen the soil to be picked up and discharged by the rotor.
