  • Patent number: 11540441
    Abstract: A high-efficiency blade for a lawn maintenance tool includes a central axis and a mounting portion located on the central axis. The high-efficiency blade includes a cutting blade and a cutting blade sharpened leading edge. A cleaning blade is vertically offset from the cutting blade and is configured to mulch the associated clippings from vegetation and reduce an associated accumulation of clippings on an underside of an associated mower deck. The lawn maintenance tool can also include a deck having a separation distance between the cleaning blade and an underside of the deck. The deck can include an elevation change to vary the separation distance. The deck and high-efficiency blade can also include a forward or rearward tilt.

  • Patent number: 11523559
    Abstract: A low-energy blade system having a quick-change attachment for a lawn maintenance tool is provided. The low-energy blade system requires a reduced amount of energy to rotate the blade system. The blade system includes a shell, a mounting plate attached to the shell, a plurality of quick-attach mechanisms, and a separate cutting blade attachable to each of the quick-attach mechanisms. Each quick-attach mechanism allows a cutting blade to be attached to the mounting plate without the need for external tools, such as screwdriver, wrench, ratchet, or the like.

  • Patent number: 11511818
    Abstract: A track drive for outdoor power equipment has a support frame with a centerline and a hub bearing attached to the support frame. A drive sprocket having a nesting interior half and exterior half is attached to the hub bearing, which enables the drive sprocket to rotate relative to the support frame. The drive sprocket is attached to an associated drive hub of a piece of outdoor power equipment. Drive sprocket teeth are spaced radially about the drive sprocket, with a first set of drive teeth attached to the interior half sprocket and located on an interior side of the support frame. A second set of drive teeth are attached to the exterior half sprocket and located on an exterior side of the support frame. The drive sprocket transmits a rotational force to an endless track to rotate the endless track and propel the outdoor power equipment.
