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.

Abstract: Provided is a track drive for outdoor power equipment including a support frame and a drive axle configured to attach to an associated drive hub. A hub bearing is mounted on the drive axle and the support frame enabling the drive axle to rotate relative to the support frame. A drive sprocket is attached to the drive axle and includes an interior half sprocket and an exterior half sprocket. The half sprockets are located on either side of the support frame. Drive teeth are spaced radially about the drive sprocket. The drive sprocket is movably engaged with an endless track to transmit force to rotate the endless track and propel the outdoor power equipment. A kit for adding or replacing a track drive of outdoor power equipment is also provided.

Abstract: A low-energy blade system having a quick-change attachment for a lawn maintenance tool. 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.

Abstract: A blower includes a frame, a surface engaging wheel attached to the frame and a power source attached to the frame. An impeller housing is also attached to the frame, and the impeller housing defines an intake opening. The impeller housing surrounds an impeller that is rotatably connected to the power source. An exhaust chute is attached to the impeller housing. A selectively closeable aperture structure is attached to the intake opening. In further examples, the selectively closeable aperture is a pair of rotatable plates both including radial slots or an iris blade assembly. In other examples, the exhaust chute is rotatable or the impeller housing is rotatable.
