Abstract
A walk-behind trenching implement has a side mounted rotary trenching tool for creating a profiled trench into the surface of the earth, which can also be used as an implement to edge landscape beds. The trenching implement is powered by an engine that delivers rotational power in an unbalanced manner to the wheel adjacent to the rotatable trenching tool. The wheel opposite to the trenching tool is can be non-powered to freely rotate as the implement is moved across the surface of the ground, or braked to unbalance power delivery through a differential. This unbalanced propulsion drive induces a skewing action into the operation of the implement that counterbalances the opposite skewing action resulting from the operation of the trenching tool to provide a more smoothly operating implement. A trenching tool having a configuration conducive to profile modification allows flexibility in the desired shape of the trench being formed.
