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.

Systems and methods for monitoring the distribution of residue material from a spreader tool of an agricultural machine including a first sensor with a sensing region defining a first sensing boundary corresponding to a first direction with respect to the agricultural machine, a second sensor with a sensing region defining a second sensing boundary corresponding to a second direction with respect to the agricultural machine, and using the sensing data from the first and second sensors to determine a distribution of residue material associated with the spreader tool. One or more systems of the agricultural machine are then controlled based on the determined distribution.

A method collects radar signals reflected from particles distributed by an emission device. A three-dimensional range-angle-velocity cube is formed from the radar signals. The three-dimensional range-angle-velocity cube includes individual bins with radar intensity values characterizing angle and range for a specific velocity. The three-dimensional range-angle-velocity cube is analyzed to identify a ground plane and radar signals reflected from particles immediately proximate to the ground plane. Total particle deposition distribution is predicted.

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 controlling spread pattern of a particulate material broadcasted by a spinner spreader involves permitting particulate material to flow through a plurality of sluices situated in a particulate material path between a bin and a rotatable disc of a spinner spreader. Each sluice receives a portion of the particulate material and delivers the portion of particulate material to a radial and/or angular position on the rotatable disc. The radial and/or angular position on the rotatable disc to which the portion of particulate material from at least one of sluices is delivered is adjusted by longitudinally translating the at least one independently moveable sluice independent of all other sluices of the plurality of sluices to change position of the at least one independently moveable sluice relative to the rotating disc thereby changing the spread pattern of the particulate material broadcasted by the rotatable disc.

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.
