A hand-held spreader is provided having a housing with a compartment for particulate material, a chamber below the compartment having a bottom wall with a circular aperture, an impeller mounted for rotation in the chamber along such bottom wall responsive to a hand crank, a discharge opening, and a path along which the particulate material passes into the chamber for discharge via the discharge opening. The impeller has an outer circular periphery proximal to and extending over an outer edge of the aperture to form a gap between the impeller and the bottom wall of the chamber that seals the gap from the particulate material larger than the gap from entering under the impeller and risking obstruction of impeller rotation. Any particulate material that enters the gap passes downward through the aperture to enable self-cleaning of particulate material that would otherwise collect under the impeller in the chamber.

A solid distribution system of an agricultural spreader includes a product hopper configured to contain solid particulate material, a blower, a manifold coupled to the blower and having a plurality of outlets, at least one boom arm comprising a plurality of parallel rigid tubes configured to carry the solid particulate material and air from the blower, and a plurality of hoses. The manifold is configured to split air flow from the blower into flows through each of the plurality of outlets. Each valve is in fluid communication with one of the outlets and one of the rigid tubes, and each valve individually controls flow through a respective one of the rigid tubes. Vehicles having such solid distribution systems are also disclosed.

A manually operable spreader which can be moved from behind on a surface is especially suitable for distributing salt and other particulate materials which tend to conglomerate or clump in a hopper of the spreader. Wheels are mounted to a frame also support the hopper. A horizontal drive shaft between the wheels is coupled to rotate a vertical shaft. A distributor below the hopper rotates with vertical shaft rotation to distribute particulate material which drop via openings in the bottom of the hopper. The vertical shaft extends via a hole in bottom of hopper and carries at the top thereof an auger having a helical vane. The auger is rotatable with the vertical shaft as the spreader is moved on its wheels. The auger circulates the particulate material in the hopper as the spreader moves while directing material in the hopper towards the bottom thereof.

Systems and methods for dispersing granular material from a supply enable enhanced directional control and throwing distance. The present invention is utilizable with an integrated granular material supply container or can be configured for adaptation to a separate supply. Some embodiments of the present invention include a supply funnel, a flexible conduit, and a launcher constructed of a relatively stiffer material having a selectably openable aperture. When fed the supply of the granular material by the conduit, and moved forward in an underhanded tossing motion, a basic coordination of a triggering of the aperture opening at the appropriate moment in the toss controllably propels a substantial amount of the granular material a significant distance.

An apparatus for dispensing a granular fertilizer onto a surface. The apparatus comprises a housing, one or more wheels, a handle, and an auger. The housing has a first end, a second end, an enclosed tubular bore, a first opening facing generally upward, a second opening facing generally downward, and a weephole facing generally downward. The one or more wheels are connected to the housing for supporting the housing with respect to the surface. The handle is configured to be grasped by a user to cause movement of the housing relative to the surface. The auger is housed within the enclosed tubular bore. Rotation of the auger transports the granular fertilizer along the enclosed tubular bore of the housing from the first opening to the second opening to control an amount of the granular fertilizer that is dispensed from the second opening onto the surface.

A hand-planter for singulation planting of cereal, grain, seed and other crops includes a tapered soil engagement component for striking and penetrating a soil surface. With each planter strike to the soil surface, the planter is actuated to meter a granular material product by reciprocating a drum to rotate, thereby exposing a cavity to a material hopper. As the actuation force is released, the reciprocating drum rotates in an opposite direction to its original location and drops the material that has been metered.
