A dual-impeller spreader capable of independently a flowrate of particulate material about two halves of the spreader's coverage area. The spreader includes a frame, a hopper, and wheels rotatably connected to the frame via an axle. A first impeller is fixed to a first impeller shaft rotatably coupled to the axle via a first gear train, and a second impeller is fixed to a second impeller shaft rotatably coupled to the axle via a second gear train. A first shut-off control selectively opens and closes a first set of hopper exit openings located above the first impeller, while a second shut-off control selectively opens and closes a second set of hopper exit openings located above the second impeller. The first shut-off control and the second shut-off control selectively open and close the respective openings independent of each other.

A bottle for storing grass seeds, soil, and/or fertilizer used for filling a golf divot is provided. The bottle includes a bottom section having a base and a perimetrical sidewall extending therefrom to an open end to define an interior. A pair of bosses extend outwardly from the sidewall at the open end. The top section has a perimetrical edge and a top surface with a spout extending therefrom for discharging the contents of the bottle. A pair of latches that extend from the perimetrical edge and pivot downwardly to engage the bosses to secure the top section to the bottom section. The bottle can also be part of an assembly that includes the bottle and a holder.

Systems and methods for managing spreading of particulate material over a surface by a spreader. One step of the method includes receiving a selection of a type of the spreader. An additional step includes receiving a selection of a type of the particulate material to be spread by the spreader. An additional step includes obtaining data indicative of a travel speed of the spreader, with the data being received from a sensor associated with the spreader. An additional step includes determining an operational attribute of the spreader. The determination is based on (i) the type of the spreader, (ii) the type of the particulate material, and (ii) the travel speed of the spreader. A further step includes presenting the operational attribute.

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.

Steering and roll control systems to counteract yaw and/or roll forces during operation of a vehicle having first and second wheeled members coupled together by an articulating joint mechanism that is configured to pivot in a yaw direction and/or a roll direction. The steering assistance systems include a biasing unit configured to apply a counteracting force to bias the first and second wheeled members toward a straight-line arrangement thereof. The roll control systems include an additional biasing unit configured to apply a counteracting force to bias the first and second wheeled members toward a level alignment arrangement of the vehicle.

A hand-held spreader is provided having a base with a mechanism for spreading particulate material response to turning a hand crank. The base is universally attachable to hoppers of different types which provide particulate material to the base for spreading. Different types of hoppers when attached to the base can adapt the spreader to spread different particulate material, such as of seed or salt. Teeth may be provided along upper edge of the hopper for use in scooping up particulate material into the hopper. Another type of hopper which can be attached to the base has a closed top end to provide a sealed container of particulate material, and has a sealing member releasable from the hopper to allow flow of particulate material from the hopper to the attached base.

A gardening material dispensing apparatus configured for dispensing gardening material. The gardening material dispensing apparatus includes a convertible container assembly configured to contain a supply of the gardening material, a dispensing conduit configured to flow the gardening material from the container assembly continually based on gravity to a selected area, and at least one material agitator assembly operably coupled to the dispensing conduit and configured to controlled quantities of the gardening material by controlling a speed of rotation of an agitator impeller.

The dispensing conduit dispenses a precise amount of the gardening material continuously onto the selected area.

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.
