Abstract
A shear capable of cutting weeds close to the ground, without cutting grass in the presence of the weeds, is described. The shear can be implemented as a battery operated hand held device or as a shear mounted on a lawn mower. The shear operates by maintaining a spacing between the blades such that the flexible grass will only be bent between the blades. Weeds which have a thicker and stiffer shaft than the grass will be cut, thus functioning as a selective mechanical herbicide.
