Abstract: A turf maintenance apparatus having folding handles facilitating compact storage is presented herein. The folding handles can be compressed or extended to adjust overall length and can rotate between an extended operator position and a folded storage position. Depending on implementation, the folding handles can be locked in the folded storage position and can also lock in the extended operator position. One or more operator presence devices can disable operation of a motor or engine when deactivated. A first operator presence device can deactivate operation of the motor or engine when the folding handles are not locked in the extended operator position, and a second operator presence device can deactivate operation of the motor or engine absent an operator maintaining activation of the second operator presence device.

Abstract: A power equipment machine with operator selectable autonomous mode and manual mode is provided. By way of example, the power equipment device can provide user-assisted semi-autonomous steering along user-defined paths of a geographic area. Manual steering controls and autonomous guidance controls can be positioned on one or more movable armrests to enhance comfort and minimize operator fatigue. The manual steering controls can include a jog wheel and encoder mechanism located on a first armrest, eliminating conventional mechanical shaft and wheel steering devices and dual lap bar steering devices. Guidance and computer settings can be accessed through a touchscreen display mounted in front of an operator position on the power equipment device.

Abstract: A method for autonomous mower (110) 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 (102), 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 mower blade (20) for a lawn maintenance device includes an elongate blade (24) having opposed end edges (26, 28) and opposed side edges (30, 34). The elongate blade (24) is adapted for mounting onto a rotary mower for rotation about a center axis (36) extended transverse to the elongate blade (24) and separating the elongate blade (24) into opposed elongate end portions (38, 40) extended from the center axis (36). The elongate blade (24) has a blade major axis (44) and defines a curved portion (54) such that the curved portion (54) is opposite a sharpened cutting edge (46). The curved portion (54) extends from the elongate blade (24) in an upward direction where the two meet and curves toward a lower face (56) of the elongate blade (24). Further examples of the mower blade (20) include the curved portion (54) being offset vertically from a sharpened cutting edge (46) to develop lift during rotation and a constant cross-section over most of the blade major axis (44).
