Abstract: A snow thrower impeller assembly (24) includes a mounting slot (84) for a wiper (70). The wiper includes a wiper portion (86) that slides into the mounting slot to mount the wiper to the impeller (54). The wiper contacts an interior wall (56) of an associated impeller housing during rotational operation of the impeller in order to limit a gap (74) between an impeller blade (66) and the interior wall. The wiper can move radially inward and outward to remain in contact with the interior wall without input from the operator. Another embodiment of the impeller assembly includes impeller blades with a first portion (116) and a second portion (118). The second portion extends at a non-zero angle from the first blade portion of the impeller blade. Improving the efficiency of a snow thrower is described in one or more methods.

Abstract: A conveyor apparatus can be (removably) secured to a turf maintenance machine and efficiently transport turf clippings out from a mowing implement of the turf maintenance apparatus. An opening in the conveyor apparatus defines an input that is positioned adjacent to a discharge port of a mow deck when secured to the turf maintenance machine. The input therefore receives turf clippings ejected by the turf maintenance machine. A driven element within the conveyor apparatus propels the turf clippings along an interior length to an output. The conveyor apparatus can be operable with a bagging mode of the turf maintenance machine, and can be removed and replaced with a discharge chute to implement a side discharge mode for the turf maintenance machine.

Abstract: An electric powered snow thrower having high efficiency and high performance is disclosed. The electric powered snow thrower can incorporate an impeller that achieves high throw distances even at significantly lower power than conventional devices. Additionally, aspects of the electric powered snow thrower enable adjustment between different performance and power levels to adjust snow throw distance to optimize performance with power consumption and battery longevity. In some disclosed aspects, the performance level is coupled with a chute deflector height to simplify a selection between low power consumption and short throwing distance and high power consumption and long throwing distance, and all ranges there between.

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: In a broad respect, vehicles that are capable of making a low- to zero-radius turn using the independent rotation of drive wheels and by turning the non-driving steerable structure or structures (such as wheels) with a steering input device (in some embodiments, the driving wheels also may be capable of being turned). This may be accomplished using a steering system, a speed control system and an integration device (together, a control system) that are configured to work together to provide correct steering in forward and reverse, and, in some embodiments, to reduce the speed of the outboard drive wheel of the vehicle when it enters an extreme turn under constant speed input. Different systems configured for use in such vehicles are included.

Abstract: A mower blade assembly attaches to a rotatable spindle and includes a mounting plate which defines a first pin aperture. The mounting plate and a retaining plate are attached to the rotatable spindle. 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 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 to the mounting plate. The blade 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.
