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.

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 distributing machine—spreading machine and/or sowing machine includes a container, receiving material to be distributed, supported by a support frame, an outlet opening on the base of the container, a metering element downstream of the outlet opening, a motor-driven metering slide displaceable relative to the outlet opening, and a distributing element downstream of the metering element, for distributing the material. For adjusting a speed of the metering slide, while providing a compact design, the metering slide of the metering element includes a threaded spindle that is mounted axially fixed and is driven in rotation by a motor rotary drive having an axially fixed output shaft. Along the threaded spindle, a spindle nut is guided that engages with the threaded spindle. The spindle nut is connected to the metering slide, or to a lever arm arrange thereon, to actuate the metering slide by rotation of the threaded spindle.

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 spraying support system for a working machine, includes: a support device including a plan creator portion to create a spraying plan representing a relation between field information relating to a field to which spray substance is sprayed and spraying information including spraying amount of the spray substance; a plan obtainer device provided to a working machine having a sprayer device to spray the spray substance and configured to obtain the spraying plan created by the plan creator portion; and a spraying controller device to control a sprayer portion of the sprayer device based on the spraying information of the spraying plan obtained by the plan obtainer device.

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.

In accordance with one or more embodiments herein, an agricultural machine (100) comprising sensors is provided. The agricultural machine (100) comprises a number of sensor programming devices (110), each comprising a unique set of sensor programming instructions, and is arranged to comprise one single corresponding sensor device (120) for each of the sensor programming devices (110). Each sensor programming device (110) is mounted in a programming position (115) adjacent a sensor position (125) for the corresponding sensor device (120), and each sensor device (120) is arranged to be mounted in the sensor position (125) and automatically receive the sensor programming instructions from the corresponding sensor programming device (110). This ensures that if a sensor device (120) is moved from one sensor position (125) to another sensor position (125), it automatically receives a different set of programming instructions.

A broadcast spreader and methods of using the same. One method includes dispersing particulate material using a broadcast spreader having a hopper and an impeller by placing the spreader in a first configuration where a first set of through openings proximate a bottom portion of the hopper permit the particulate material to pass therethrough and fall onto the impeller to thereby be distributed in a first spread pattern, and shifting the spreader into a second configuration where a second set of through openings proximate the bottom portion of the hopper permit the particulate material to pass therethrough and fall onto the impeller to thereby be distributed in a second spread pattern. The first set of through openings includes a different number of through openings than the second set of through openings, and the first spread pattern is different than the second spread pattern.

An apparatus for broadcasting particulate or granular material over a ground surface involves a variable speed spinner and a material conveyor. The spinner is positioned generally horizontally below a discharge end of a material conveyor. The spinner has a disk having a generally radially disposed fin fixed to an upper side of the disk and radiating outwardly from a center of the disk. The spinner is positioned to receive material from the material conveyor at a location about half way along a length of the fin. In a method broadcasting particulate or granular material over a ground surface, the spinner is preferably rotated at a speed of 900-1000 rpm. The apparatus and method provide for distribution of material over greater distances and can do so without pulverizing the material, creating a uniform pattern of distribution over a 50% wider swath.

A method for identifying a flow of commodity through a commodity distribution system. The method including providing a tank configured to contain a commodity, selectively distributing commodity from the tank to a drill assembly to be distributed to an underlying surface, and monitoring the flow of commodity from the tank to the drill assembly with a camera to identify flow characteristics.
