Abstract
A continuous ditch excavator includes an excavating auger rotatably mounted on a chassis in a centrally-disposed excavation work area defined by forward and rear portions. Two driving elements are rotatably-mounted in laterally spaced-apart relation to each other on the chassis. The auger is moved laterally between the first and second driving elements to permit adjustment of the position of the auger in relation to the first and second driving elements. In another embodiment, the auger is carried by an arm rotatably mounted to the chassis. In yet another embodiment, the excavator includes a plurality of excavating augers independently raised and lowered to vary the width of the ditch.
