US Classification:
37348, 37352, 172 3
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.

Appl. No.:

International Classification:
E02F 508
US Classification:
37189
Abstract:
A trencher has an adjustable depth arbor support mechanism. The depth control mechanism includes a linkage which normally controls the depth of the trench being dug, but which also will allow the arbor to retract from the ground if it hits an obstacle. Preferably, the arbor support mechanism is at least partially counterbalanced by a spring, to allow the arbor to retract without undo force. The 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. The cutting teeth are mounted to the arbor using a variety of chucks and mounting brackets, so the width of the trench is adjusted by adjusting the chucks and mounting brackets used.
