<p>A trenching machine (10) having independently driven wheels. The trenching machine (10) comprises digging chain (20) that moves between a raised position and a lowered position, a housing (30) that is carried by a pair of front wheels (40, 50) and a pair of rear casters (60), a motor (70) that independently drives front wheels (40, 50) to propel housing (30), and a guide wheel that aligns the trenching machine with the trench upon a second pass. The trenching machine (10) also has a front plow (400) and a rear plow (500) that collect and deposit the dirt surrounding the trench into the trench. A method of gardening/landscaping wherein a trench is dug by a first pass, soil amendments are added to the trench, and then on the second pass, the excavated dirt is plowed back into the trench and then mixed with the amendments. A method of gardening/landscaping wherein vegetation cover between trenched rows is maintained.</p> |
