  • Publication number: 20200281113
    Abstract: A powered hand-held spreader device is disclosed that has a handle that allows a user to grip and hold the device with one hand. The spreader includes an adjustable shutter, controlled by a rotary dial, to allow for distribution of a range of different granular products that require different flow rates for distribution. The granular product is contained in a hopper. The product can be distributed over various types of terrain, including, but not limited to, lawns, gardens, and paths. The spreader is driven by an electric motor actuated by a trigger. A spinning rotor plate distributes the granular product fed from the hopper. A trigger lock is optionally available to lock the trigger in the “on” position during use and to prevent actuation when the trigger is in the “off” position. An adjustable side deflector optionally can be used to control the distribution pattern of the granular product.

  • Publication number: 20200053956
    Abstract: A spreader for broadcasting granular or particulate material over a surface includes a dual rotor configuration, a material deflection system, and a portable electronic device holder. The material deflection system includes components for deflecting material broadcasted by each of the rotors. The spreader includes a walking speed indicator to inform the user whether the current speed is too fast, too slow, or within an acceptable reference range.
