Abstract
A folding boom side-ditcher which has a two-stage chain (or belt) drive from the power take-off (PTO) of a tractor. A laterally movable counterweight is provided so the folding boom has maximum side reach without danger of upset. Hydraulic actuating cylinders are provided for moving and positioning the boom and the counterweight, which are connected to the hydraulic system of the tractor in the conventional manner. The two-stage chain (or belt) drive for operating the digger head transfers more power through a two-stage reduction sprocket system, and the digging capacity at the digger head is increased substantially. This side-ditcher is more versatile because of the flexible boom, and it is considerably less expensive than the prior hydraulic drive systems of conventional side-ditchers.
