Abstract
A herbage trimmer has a larger, toothed rotatable cutting blade provided with a circular array of bosses. A smaller, toothed rotatable cutting blade lies flat against the larger blade and is positioned within the tooth tip circle of the larger blade so that some of its teeth overlap with some of the teeth of the larger blade. The bosses on the larger blade are in gear-tooth relationship with the teeth of the smaller blade so that the blades counter-rotate to produce a continuous shearing action between the over-lapping teeth of the blades.
