  • Patent number: 11690315
    Abstract: An autonomous lawn mower includes removable batteries, one or more electric motors, a cutting blade, one or more wheels, an angle sensor, and a controller. The cutting blade is driven by one of the electric motors. The wheels are driven by one of the electric motors. The controller is configured to allow the lawn mower to perform a grass cutting function at a jobsite without human interaction. The controller is configured to determine whether a roll angle is greater than a first predefined amount using data from the angle sensor. In response to determining the roll angle is greater than the first predefined amount, the controller is configured to stop operation of one of the one or more electric motors configured to provide rotational drive power to the cutting blade.

  • Publication number: 20190015853
    Abstract: A spray gun for use with a pressure washer includes a spray gun body, an inlet, a primary flow path for conducting a primary fluid flow, a secondary flow path for conducting a secondary fluid flow, and an inlet flow path for receiving a flow of pressurized water from the pressure washer via the inlet. The inlet flow path directs the pressurized water into the primary flow path. The spray gun further includes multiple chemical containers carried on the spray gun body, each chemical container configured to contain a different chemical, and a selector valve movable among a number of positions to fluidly couple one of the chemical containers with the secondary flow path.
