A portable granular material spreader including an enclosure adapted to dispense granular material through an outlet, and a pressurized air source. A chamber has first, second, and third passageways, and containing a distributor therein, the first passageway in fluid communication with the outlet to receive the granular material by virtue of gravity from the outlet with the distributor controlling a flow rate of the granular material in the chamber, the second passageway in fluid communication with the pressurized air source, and the third passageway for discharging the granular material entrained in pressurized air from the pressurized air source. A conduit being in fluid communication with the second passageway and the enclosure, the conduit end being sufficiently distal from the outlet to not result in aerating the granular material proximate the outlet while preventing a reverse flow of the granular material at the outlet during operation of the spreader.

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.
