Abstract
A power-driven rotor is mounted on a support and its cylindrical wall is provided with helically-arranged, elongated slits in which blades or rasps are removably inserted, the rasps having a series of teeth disposed along portions of helices co-axial with the rotor and protruding from the cylindrical wall. The apparatus is more particularly used as a grass and bush mower, and in a modified embodiment also as an ice- and snow-blower.
