A metering system and method of operating fertilizer distribution equipment, such as a spreader-sprayer, is described that includes monitoring revolution data for opposing left and right wheels with left and right sensors. A controller controls an actuator's operation to operably regulate the output of a liquid and/or solid fertilizer product. The fertilizer output is based at least in part on the revolution data and a fertilizer unit-per-area input.

An agitation unit for use in a lawn spreader and other dispensing equipment, and oscillating agitation systems therefor comprising such an agitation unit. The agitation unit includes a hub, an arm extending from the hub, and an extension on the arm configured to project downwardly to an extent relative to the arm and the hub to protrude into, but not through, the outlet passageway of the hopper.

A loader bucket has material spreaders on opposing sides of the loader bucket to spread material from within the loader bucket received through discharge openings in the rear wall of the bucket from an auger located in the bottom of the bucket. Each material spreader includes a spinner formed with blades to spread the material received through the discharge openings. The material spreaders are positioned below the apex of the V-shaped bucket and operable within a path of distribution that includes an interior boundary member oriented with a forward end closer to the center of the bucket than the rearward end to provide a distribution forwardly and laterally of the bucket. A low baffle mounted at the bottom periphery of the spinner blades forces material upwardly into a fluffy pattern. A high baffle provides a second boundary limit for the distribution of material.

The invention relates to a method for regulating the throwing behavior of a centrifugal spreader for fertilizer and to a centrifugal spreader configured therefor. According thereto, a target throwing distance is determined for a target working width. Furthermore, one of several rotational speed levels is selected for at least one spreading disc to approximate the actual throwing distance to the target throwing distance. Finally, an adapted target throwing angle for regulating an actual throwing angle is determined from the actual throwing distance (WW1) and counteracts in a compensatory manner a deviation from the target working width caused be the difference between the actual throwing distance and the target throwing distance. Continuous regulation of the throwing distance then becomes unnecessary, resulting in more stable regulation of the overall throwing behavior.

A spreader assembly to distribute materials on a ground surface, including a container to hold the materials, a frame affixed to the container, a beater assembly supported by the frame that receives the materials from the container and processes the materials to obtain processed materials, and a spinner assembly that receives the processed materials and expulses the processed materials from the frame onto the ground surface. The beater assembly includes a pair of rotating elements that blends the materials to produce the processed materials, and a deflector located between the pair of rotating elements configured to prevent the formation of agglomerates in the processed materials.

A control apparatus for a broadcast spreader includes a gate adjustment dial mounted on, and generally coaxial with, a handle portion of a handle assembly of the spreader. Rotation of the gate adjustment dial in a first direction causes an increase in a current maximum discharge rate of the spreader and rotation of the gate adjustment dial in a second direction causes a decrease in the current maximum discharge rate of the spreader.

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 material discharge system having at least one rotating member disposed within at least one chamber of a holding container. Each rotating member has a central hub with a plurality of arms that extend radially and transversely away from the central hub. The holding container has at least one discharge chamber.

A method for spreading broadcasting material using an agricultural spreader is provided, and in particular with an open-loop and/or closed-loop control device in which open-loop and/or closed-loop control with at least one adjustment parameter is provided for the spreader and is configured to influence on the basis of the at least one adjustment parameter a spread pattern of the broadcasting material that can be spread by the spreader, where a need for the adaptation of a control behavior of the at least one adjustment parameter is detected, and after the detection of the need for the adaptation of the control behavior, the control behavior of the at least one adjustment parameter is adapted; where a need for adjustment parameter adaptation for influencing the spread pattern is additionally detected, and one or more adjustment parameters with adapted control behavior are changed after the need for adjustment parameter adaptation has been detected.
