Filed:

Jun 7, 1994

Appl. No.:

8/254954

Inventors:

Frank R. Allen - Columbia SC

International Classification:

A01D 3483

US Classification:

56244

Abstract:

A cutter head for a lawn mower which has a plurality of fingers arranged in two sets, one above the other, that extend forward in the direction of travel to channel grass between them. Between the fingers is a conveyor belt carrying a set of short blades moving transverse to the direction of motion of the mower for shearing the grass that is channeled by the fingers. The blades are preferably arranged at different levels to mulch the grass. Each blade is preferably split and bent to form multiple cutting edges at different levels. In one embodiment, the lower set of fingers extends farther forward than the upper set to better lift the grass for cutting. In an alternate embodiment, the upper set of fingers extends forward of the lower set and curves downwardly to lift objects out of the path of the mower. The continuous conveyor belt is conveyed around three sheaves that carry the plurality of blades and a sweeper to sweep grass from the cutter head.

Inventors:

Frank R. Allen - Columbia SC

International Classification:

A01D 3483

US Classification:

56244

Abstract:

A cutter head, for a non-rotary power lawn mower, having a multiple-blade, multiple levels of blades assembly. The cutter head includes a stationary assembly in the form of a plurality of fingers arranged in several levels that cooperate with a continuous plurality of blades moved by a blade-carrying assembly. The fingers preferably extend parallel to the lawn mower's direction of motion in order to catch the grass and set it up for cutting. The blade-carrying assembly is preferably a chain conveyed around a pair of sprockets that carry the plurality of blades. These blades are arranged in several levels and interleave several levels of fingers. The grass entering the spacing between the fingers is sheared at each level of the stationary assembly by movement of the blades across the fingers. The cut grass is directed to the rear area of the cutter head, where it falls below the cutter head as mulch.
