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 high-efficiency cutting system for an autonomous mower provides a multiple blade tip cutting radius for a cleaner cut, and more complete mow. The system includes a spinning blade disk provided within a housing including a vertical standoff. The blade disk includes a first pair of cutting blades located between the center of the blade disk and the circumference of the blade disk, and a second pair of cutting blades located radially inward from the first pair of cutting blades. The cutting blades extend downward and away from the blade disk at an angle.

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.

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.
