Abstract
A multi-segmented lawn mower cutting blade and lawn mower including same. The blade may include a hub defining a rotational blade axis and an elongate arm. The arm includes: an origin connected to the hub; a first segment extending outwardly away from the hub in a first direction from the origin to a distal end of the first segment; and a second segment extending from the distal end of the first segment in a second direction, the second direction being different than the first direction. At least a portion of the arm forms a cutting surface configured to cut vegetation as the blade rotates about the blade axis.
Claims20
A lawn mower cutting blade comprising:
- a hub defining a rotational blade axis;
- and
- an elongate arm comprising:
- an origin connected to the hub;
- a first segment extending outwardly away from the hub in a first direction from the origin to a distal end of the first segment;
- and
- a second segment extending from the distal end of the first segment in a second direction, the second direction being different than the first direction,
- wherein at least a portion of the arm forms a cutting surface configured to cut vegetation as the blade rotates about the blade axis.
A toroidal lawn mower cutting blade comprising:
- a hub defining a rotational blade axis;
- and
- at least two elongate arms, each arm supported by the hub and comprising an origin and a terminus both located at or near the hub such that each arm forms a closed loop defining a window, wherein at least a portion of each arm forms a cutting surface configured to cut vegetation as the blade rotates about the blade axis.
A rotary lawn mower comprising:
- a cutting deck comprising an upper surface and one or more sidewalls extending downwardly from the upper surface to define a downwardly opening cutting chamber;
- a shaft extending through the upper surface of the deck, the shaft defining a shaft axis;
- and
- a toroidal lawn mower cutting blade contained withing the cutting chamber, wherein the blade comprises:
- a hub connected to the shaft, the hub defining a rotational blade axis coaxial with the shaft axis;
- and
- at least two elongate arms, each arm supported by the hub and comprising an origin and a terminus both located at or near the hub such that each arm forms a closed loop defining a window, wherein at least a portion of each arm forms a cutting surface configured to cut vegetation as the blade rotates about the blade axis.
