Methods and systems are presented for making good use of recently obtained biometric data, for configuring propagule capsules (e.g. containing seeds or spores with growth media and other helpful materials) for deployment via drones so that each has an improved chance of survival, and for configuring drones or piloted craft for safe fleet deployment in remote locations.

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.

A spreading device includes a containing unit to contain a spread material, a first spreading unit including a first rotating body to spread the spread material contained in the containing unit, a second spreading unit including a second rotating body to spread the spread material contained in the containing unit, a first driving source of which speed is changeable, a first shaft to transmit power provided from the first driving source, a second shaft to transmit power provided from a second driving source different from the first driving source, and a power transmission mechanism to receive power from the first shaft and power from the second shaft, the power transmission mechanism being capable of transmitting the power received from the first shaft and the power received from the second shaft to the first rotating body and the second rotating body.

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.

An adhesive mat for determining a distribution of agricultural spreading material by imaging, includes: a collecting region which is bordered on one side by an edge region, where the edge region includes a passage opening and/or a handle.

A distributing machinespreading 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.

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.
