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 work management system includes a generator attached to a structure body that is provided to a transmission case of a working machine, configured to be driven by power transmitted from a PTO shaft, and configured to transmit power to a working device provided in the working machine, an information obtaining portion configured to obtain operation information representing operation of the working device that is activated by the power from the generator, a work management portion configured to manage working of the working device based on the operation information obtained by the information obtaining portion, and a controller portion configured to control the working device based on the operation information obtained by the information obtaining portion.

The invention relates to a method for spreading spreading material onto agricultural land (12) by way of an agricultural spreader (10), with the steps of: providing information on spreading boundaries (14) of agricultural land (12) to an electronic control device and moving the agricultural spreader (10) in the direction of a predetermined activation point in the vicinity of a spreading boundary (14) of the agricultural land (12) at which the start of dispensing spreading material onto at least one spreading disk is intended, where, while the dispensing of the spreading material is interrupted, the electronic control device automatically induces an anticipatory setting for a start configuration predetermined for the activation point at the agricultural spreader (10) before the agricultural spreader (10) reaches the activation point.

A feed control system for a spreader includes a section configuration module configured to output a section configuration and a section control module configured to receive the section configuration, determine a first actuator position based on the section configuration, and determine a second actuator position based on the section configuration. The feed control system also includes a belt speed module configured to receive the section configuration, receive a commanded belt speed, and determine a target belt speed based on (i) the section configuration and (ii) the commanded belt speed.

An agricultural aircraft for spreading granular fertilizer and a spreading method thereof. The agricultural aircraft includes an aircraft body, a power system, and a spreading device, where the spreading device is located at a front part of the aircraft body, and the aircraft body is also provided at the front thereof with a wind direction sensor and a wind speed sensor communicatively connected a controller; the spreading device includes a box body, a throwing disc, and a tray connected to the box body, where a left baffle plate and a right baffle plate with controllable opening angles are disposed on the tray; an upper part of the box body is a material box for storing granular fertilizer, a cavity for accommodating the tray and the throwing disc is disposed on one side of the box body.

A broadcast spreader, components thereof, and associated methods. The broadcast spreader includes a hopper, a spinner, a motor for turning the spinner, and a material feeder configured to feed granular material from the hopper to the spinner. The broadcast spreader includes a material feeder adjustment actuator, a spinner speed control actuator, and a motor on/off actuator. A harness wearable by a person is configured to carry the broadcast spreader. A kit of interchangeable battery adaptors enables use of different brands or models of batteries.

A distribution machine, in the form of a spreader or a seed drill, includes a container carried by a support frame for receiving pulverent or particulate material to be distributed. An outlet opening is arranged on a floor of the container. A metering member is arranged downstream of the outlet opening. A ground distribution member is arranged downstream of the metering member. A displaceable part, such as a metering slide of the metering member or a device, adjusts the delivery point of the material to be distributed onto the distribution member. The displaceable part is operatively connected to, and actuated by, an output shaft of an electromotive rotary drive, a servomotor or a transmission output shaft of a transmission, arranged downstream of the electromotive rotary drive such that the exclusively rotational movement of the output shaft or of the transmission output shaft is transmissible to the displaceable part.

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.

A method of spreading granular material by an agricultural distribution device includes the steps of: spreading granular material onto an agricultural land by a plurality of distribution elements arranged on a distribution linkage of the agricultural distribution device, and detecting plant rows on the agricultural land during the spreading of the granular material, wherein the granular material is spread in row areas of the agricultural land having plant rows by at least one distribution element with a first distribution pattern and is spread in row-free areas of the agricultural land not having plant rows by at least one distribution element with a second distribution pattern.

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.
