Abstract
A trencher has two wheels equidistant on either side of the arbor, and a third steerable wheel at the front of the trencher in line with the arbor. Speed of the arbor, forward motion of the trencher and the direction of motion are determined by motors controlled by an onboard control system. The onboard control system is controlled by a remote control, which may be a simple manual wireless controller or a programmable computer. With a programmable computer, the trencher can be pre-programmed to dig along a pre-selected path, e.g., a logo, flower or other design.
