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.

Abstract: A method for autonomous mower navigation includes performing a training operation for an area including identifying a GPS signal associated with a training apparatus, iteratively recording data associated geolocations of the training apparatus as the training apparatus moves along a trajectory through the area, smoothing the geolocation data associated with the trajectory, and storing the smoothed geolocation data. The method can include subsequent to the training operation, performing a greens association process including establishing a link between the autonomous mower and an RTK-GPS base, receiving by the autonomous mower correction data from the RTK-GPS base, and determining an approach angle to a work area, wherein the path the autonomous mower travels to the work zone is defined by the approach angle.

Abstract: A multi-mode trimmer head for use with an outdoor handheld tool such as a string trimmer, brush cutter, or the like is provided. The trimmer head includes an upper housing, lower housing, bump head, spool, and a spring. The spool includes a first pair of apertures configured to receive a pair of flexible trimmer lines to provide a bump-feed operating mode for the trimmer head. The spool also includes a separate, second pair of apertures configured to receive a single fixed-line trimmer line to provide a fixed-line operating mode for the trimmer head. The trimmer head is switchable between the fixed-line operating mode and the bump-feed operating mode without the need to disassemble the trimmer head.

Abstract: A chute control assembly for a snow thrower having a housing, handle, and a chute includes a control mechanism, a connecting mechanism, and a guide mechanism. The control mechanism includes an actuator mechanism that allows an operator to manually control the orientation of the chute from a position spaced apart from the chute. The connecting mechanism transfers rotation of the actuator mechanism to the guide mechanism. The guide mechanism is attached to the chute and rotates and adjust the orientation of the chute in response to rotation of the actuator mechanism in order to change the direction that snow is thrown from the snow thrower.
