ABSTRACT:
Apparatus for breaking up vegetable matter is disclosed. The apparatus may be stationary, material being delivered thereto for treatment, or mobile; e.g., a lawn mower which is moved over a lawn to cut grass. Other mobile embodiments will include apparatus for reaping or harvesting crops more generally. In both the stationary and mobile forms, the apparatus disclosed includes an elliptical blade obliquely mounted on a shaft such that the periphery of the blade generates a cylindrical surface upon rotation of the shaft. Material is cut by the shearing engagement of the periphery of the blade with an edge lying on the cylindrical surface. Cut material is carried into the rotational "cylinder" and discharged radially therefrom. In preferred stationary embodiments of the invention the "cylinder" will be positively defined by a drum having inlet and outlet openings in the cylindrical surface thereof, the openings defining the edge at which initial cutting is effected. In preferred mobile embodiments, the cutting edge will be formed on a plate extending around a part of the cylindrical surface to the point of discharge.
