Abstract: Vehicle-mounted line trimmers and/or edgers for weed and vegetation, along with methods of operation of such trimmers, are discussed. The trimmer/edger can have a variety of features such as maintaining and/or adjusting the height of the trimmer/edger and maintaining the same orientation of the trimmer/edger at a variety of heights. The methods of operation can include methods for recording a path for the trimmer/edger and/or following a pre-recorded path for the trimmer/edger, trimming/edging around small obstacles, and trimming/edging along large obstacles.

Abstract: A method of removing debris from an area of turf grass can include providing a grass treatment system including a comb having a leading edge comprising a plurality of comb teeth, wherein the comb is mounted transversely to a direction of travel, and a substantially cylindrical brush positioned above the comb and configured to engage at least a portion of a top surface of the comb, wherein the brush rotates relative to the comb. The method can include positioning the grass treatment system closely adjacent to the turf grass such that the comb engages debris on and around the turf grass surface, and moving the grass treatment so that (i) the comb engages the debris, (ii) the rotating brush removes at least a portion of the debris from the surface of the comb, and (iii) the rotating brush does not come into contact with the turf grass.

Abstract: A lawn maintenance device has a transverse center line, a frame, and a power source including an output shaft attached to the frame. The lawn maintenance device further includes a rotating cutting blade. A left side is located on one side of the transverse center line and a right side located on a second side of the transverse center line. A plurality of ground engaging members are attached to the frame enabling movement of the lawn maintenance device along an associated driven surface. The ground engaging members on the left side are located at a first distance from the transverse center line that is different from a second distance that those on the right side are located from the transverse center line. Another example includes ground engaging members on opposite sides of the lawn maintenance device being located at different distances from a central axis of the cutting blade.

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: A biasing element provides suspension between a pivoting component and a support area of a riding outdoor power equipment vehicle, and can include a body compressible between a default unbiased orientation and a compressed orientation. The body can include annular portions having a radially outer main portion circumscribing radially inner portions. The radially inner portions being vertically spaced apart when the body is in the default orientation and movable into engagement with one another upon compression of the body.

Abstract: A mobile outdoor power equipment machine for performing a controlled task within a work area includes a drive system for providing movement of the machine, a working apparatus for performing the task, and a scanning system for scanning an area surrounding the machine. The scanning system is configured to provide detection of physical elements in the environment to aid in navigation of the machine. In an embodiment, the scanning system and a control system are configured to scan the area, determine the presence of a physical element in the area, determine that the physical element is located within the work area, determine the proximity of the physical element to the machine, determine a confidence level of whether the physical element is an animate being, and direct a behavior of the machine correlating to a combination of the confidence level and the proximity.

Abstract: A riding outdoor power equipment vehicle, such as for grounds maintenance, having a chassis including a support area, an operator platform for supporting a rider and supported by the chassis, and a suspension assembly. The suspension assembly is configured to resist movement of the operator platform towards the support area of the chassis and includes a biasing element having a plurality of annular portions. At least two annular portions of the plurality of annular portions are spaced apart from one another when the biasing element is in a default orientation and are moved into engagement with one another upon compression of the biasing element between the operator platform and the support area. Compression of the biasing element provides an initial deflection response that decreases substantially in response to increasing loading being applied to the operator platform.

Abstract: A three-stage snow thrower having a housing, a power supply operatively connected to said housing, a longitudinal drive shaft extending from the power supply into the housing, and a lateral drive shaft extending rotatably attached to opposing side walls of the housing and being meshingly engaged with the longitudinal drive shaft within a gear assembly. The power supply drives the longitudinal drive shaft, thereby causing the longitudinal drive shaft to rotate, and at least a portion of such rotation is transferred to the lateral drive via a gear assembly. The first stage assembly includes a plurality of augers attached to the lateral drive shaft, wherein the first stage assembly pushes loosened snow axially toward the gear assembly. The second stage assembly includes at least one auger attached to the longitudinal drive shaft, wherein the second stage assembly pushes the snow from the first stage assembly axially rearward in a transverse manner relative to the first stage assembly. The third stage assembly includes an impeller that rotates to throw the snow from the second stage assembly through a chute attached to the housing to expel the snow from the housing.
