ABSTRACT:
A combination machine for trenching, for forming the edge of a bed, and for laying and burying tubing, cable, piping, and the like. The machine includes steerable caster wheels mounted on the rear of the machine which, together with a single front wheel, allow for a tight turning radius when using the machine. The machine also includes a blade height adjustment which allows for the trenching or edging blade depth to be readily adjusted in a substantially infinite variation. Other aspects of the present invention include an edging machine and a trenching machine, both being of a compact design. Both include an extendable handle which, in a preferred embodiment retracts or folds to allow for the volume of space occupied by the machines to be minimized, preferably, to the extent that either of such machines can typically be carried in a trunk of a standard automobile.
