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 mower blade assembly (20) attaches to a rotatable spindle (24) and includes a mounting plate (54) which defines a first pin aperture (68). The mounting plate (54) and a retaining plate are attached to the rotatable spindle (24). The retaining plate (70) defines a second pin aperture (76). A movable pin plate (78) comprises a pin (80). A blade (26) 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 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 (204).

Abstract: The parking brake system for a lap bar controlled lawn maintenance vehicle includes at least an actuation assembly and a stop assembly. The actuation assembly includes a push arm and a rotatable pedal arm, and the push arm is attached to a lap bar and is rotatable between and engaged position and a disengaged position. Rotation of the push arm from the disengaged position to the engaged position causes rotation of the pedal arm, and such rotation of the pedal arm causes the stop assembly to prevent the axle for the rear wheel that is controlled by the corresponding lap bar from rotating.
