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 pneumatic delivery system for particulate agricultural products includes one or more compartment for containing and supplying one or more particulate product. An inductor assembly separately receives and fluidizes the particulate products and conveys the fluidized products to a metering assembly. The metering assembly separately meters each of the product flows and transfers the metered flows to one or more delivery units for applying the products. The pneumatic delivery system can be used on various implements, including planters and applicators for applying seeds, fertilizer, pesticides and other products.

Disclosed is an assembly for a dosing system of a spreader machine for distributing a granular material or the like, which comprises first and second members provided with first and second openings, respectively, and an actuator connected to at least one of the first and second members and configured to provide a driving force between the first and second members, thereby, adjusting an opening size of a dosing opening provided by an overlapping area between the first and second openings. The first and second members are moveable by relative movement into a first position providing the dosing opening with a first opening size and a second position, different from the first position, providing the dosing opening with a second opening size different from the first opening size, wherein a center portion of the dosing opening is locally fixed when the members are moved between the first and second positions.

A planting system includes a seed flow controller coupled to a hopper and a spreader. The seed flow controller, hopper, and spreader are transported by an unmanned aerial vehicle to spread the seeds over a geography. The seed flow controller includes several rollers having apposed outer surfaces. The rollers also include fins that extend about respective roller axes such that the fins cross at discrete contact points as the rollers rotate. The interfacing rollers break up clumps of seed material stored in the hopper and controllably convey the seed material from the hopper to the spreader. The spreader has a spinning spreader plate that flings the seed material laterally outward to spread the seed material over the ground.

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 dry product spreader is provided that includes a bin that includes a bin discharge opening. The dry product spreader further includes a conveyor located at the bottom of the bin. The conveyor is capable of discharging dry product material from the bin through the bin discharge opening. The dry product spreader further includes a spinner assembly for spreading the dry product material and positioned to receive the dry product material from the bin discharge opening. The dry product spreader further includes a material conveyance system to displace dry product material received through the bin discharge opening before the dry product material reaches the spinner assembly. The dry product spreader further includes a distribution manifold configured to receive dry product material displaced by the material conveyance system. The distribution manifold is configured to return dry product material displaced by the material conveyance system to be spread by the spinner assembly.

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.

A broadcast spreader broadly comprising a frame, a hopper, an impeller, a set of wheels, and an electric hub motor. The hopper is supported by the frame and configured to hold a particulate material. The impeller is rotatably connected below the hopper and is configured to receive the particulate material from the hopper and spread the particulate material over a surface. The wheels are rotatably connected to the frame for traversing the surface. The electric hub motor is at least partially positioned in one of the wheels and configured to drivably engage the one of the wheels to propel the hopper along the surface.

A method of spreading granular material by a spreader utilizes first and second rotatingly drivable centrifugal disks arranged side by side, and includes steps of: detecting a field-internal spreading boundary, which extends ahead of the spreader in a direction of movement of the spreader and which necessitates an adaptation of distribution characteristics of the spreader during traveling on at least one tramline; reducing an amount of granular material applied to the second centrifugal disk, which is part of the spreader and which faces the field-internal spreading boundary, during traveling through a first range close to the field-internal spreading boundary; and increasing the amount of granular material applied to the first centrifugal disk, which is part of the spreader and which faces away from the field-internal spreading boundary, during traveling through the first range close to the field-internal spreading boundary.

A powder/granular material spreader that allows easy cleaning of a passage for powder/granular material includes a housing that houses motors, a passage that extends through the housing and provides a passage for the powder/granular material, a roller provided in the passage to feed the powder/granular material and that is driven by one of the motors, and a spinner driven by the motor to spread the powder/granular material. The passage includes an integral first wall that shields the motor from the passage, an integral second wall that shields the motor from the passage, and an opening located at an inlet of the passage. The opening is integral with the first wall and the second wall. The housing includes an integral cover that covers tops and sides of the motors, and fits over an outer surface of the opening. A seal is provided at a location where the opening and the cover are connected with each other.
