Abstract: A portable hand-held shear for cutting grass and the like comprising a housing enclosing an electric motor and forming a handle. The motor includes an output rotary shaft which, through a gear train, drives a rotary blade. A stationary bed knife assembly connected to the housing cooperates with the rotary blade in scissor-like fashion to cut grass.An improved cutting assembly is described in which the rotary cutting blade member, of particular design and positioned in a floating relationship above the stationary bed knife assembly, is inclined into engagement with the cutting teeth projecting from the stationary bed knife assembly, also of particular design, in such a manner to improve the performance of the shear. The improved cutting assembly further includes a rotary hub drive member which cooperates with the shear housing and the bed knife to eliminate clogging and partially overlaps the bed knife assembly's cutting teeth to further improve the performance of the shear.
