ABSTRACT:
A tractor-towable sidewalk edging device includes a pair of laterally spaced cutting blade members and the depth of the cut the blade members make in vegetation to be trimmed is controllable by adding or removing weight members to receptacle members which form a part of the device. The lateral spacing between the cutting blade members is adjustable in three different ways. Each cutting blade member may also be pivoted about a vertical axis.
