Abstract: A high-efficiency lawn maintenance tool (20) includes a frame (24) and a deck (28) attached to the frame (24). A handle (38) is connected to the frame (24) and/or the deck (28) and is configured to be engaged by an operator to move the high-efficiency lawn maintenance tool. A plurality of ground engaging members (26) are attached to the frame (24). A power source (34) is attached to one of the frame (24) and the deck (28). The power source (34) is connected to a drive shaft (36) that passes through the deck (28). A high-efficiency blade system (48) is attached to the drive shaft (36). The depth of the deck (28) is about the same as the depth of the high-efficiency blade system (48).

Abstract: A mower blade assembly (20) attaches to a rotatable spindle (24) and includes a mounting plate which defines a first pin aperture. The mounting plate and a retaining plate are attached to the rotatable spindle (24). The retaining plate defines a second pin aperture. A movable pin plate comprises a pin. A blade is selectively attachable to the mounting plate. The blade defines a retaining plate aperture and a third pin aperture. A biasing member (98) urges the movable pin plate from a disengaged position to an engaged position. The pin is engageable with the pin apertures for mounting and retaining the cutting blade (26) to the mounting plate. The blade (26) is attached by moving the blade over the retaining plate aperture, urging the movable pin plate to the disengaged position, rotating the blade, and releasing the movable pin plate. Another embodiment includes a force finger.

Abstract: A multiple-stage snow thrower having a housing, a power supply operatively connected to a plurality of drive shafts for rotating a plurality of stage assemblies. Each stage assembly of the multiple-stage snow thrower is configured to move snow either axially along the axis of rotation or radially away from the axis of rotation. The first stage assembly is configured to expel snow from the housing, thereby throwing the snow away from the snow thrower. The second, third, and fourth stages assemblies are configured to push the snow toward the longitudinal centerline of the housing and then rearwardly toward the first stage assembly.

Abstract: A high-efficiency lawn maintenance tool includes a frame and a deck attached to the frame. A plurality of ground engaging members are attached to the frame, and a power source is attached to one of the frame and the deck, wherein the power source is connected to a drive shaft that passes through the deck. A high-efficiency blade system is attached to the drive shaft. A controller is electrically connected to the power source, and the controller is configured to correlate the load and/or the mower groundspeed independent of an operator's control. Other examples include reduced operating speeds of the drive shaft and commensurate reduced tip speeds of a set of cutting blades.
