Agricultural machines and implements have a need to adapt to changing environments. A closing system for an agricultural machine has a need to adapt to changing ground surface. The closing system includes a closing device pivotably connected to the agricultural machine, a passive mechanical element that is operable to apply an initial amount of force to the closing device, and an actuator that is operable to apply an actuator force to the passive mechanical element to increase the amount of force that the passive mechanical element applies to the closing device. The actuator can be a linear actuator having an adjustable stroke length to vary the amount of actuator force applied to the passive mechanical element. The passive mechanical element is operable to absorb a shock force as the closing device traverses a ground surface. The passive mechanical element includes one or more springs adjacent the actuator.

Agricultural machine adjusting mechanism

An agricultural machine includes a material distribution system and a sensing system including a first sensor configured to generate an indication of a first measure of a first flow of agricultural material in a first material distribution line, a second sensor configured to generate an indication of a second measure of the first flow of the agricultural material in the first material distribution line, and a third sensor configured to generate an indication of a measure of a second flow of the agricultural material in a second material distribution line. A control system is configured to detect occurrence of an anomalous operating condition based on the measure of the second flow and at least one of the first measure of the first flow or the second measure of the first flow of the agricultural material.

An agricultural implement and a metering apparatus for the agricultural implement to deliver a material to a material depositing apparatus. The metering apparatus includes metering roller, an integrated motor operatively connected to the metering roller, and a motor drive operatively connected to the integrated motor. A controller is operatively connected to the integrated motor and to the motor drive wherein the controller transmits a drive signal to drive the integrated motor and receives a status signal from the integrated motor. The drive signals drives the motor, which includes the roller coupled to a motor spindle, at a variable rate of speed to reduce pulsing. In one embodiment, the agricultural implement is an air cart.

An agricultural machine includes a seeding system having a seed transport mechanism configured to transport a seed along a transport route, a seed sensor configured to sense presence of the seed at a first location along the transport route, and a motor configured to drive movement of the seed transport mechanism to transport the seed from the first location to a second location in which the seed is released from the seed transport mechanism. A processing system is configured to track a position of the seed along the transport route based on an indication of the sensed presence of the seed at the first location and detected movement of the seed transport mechanism, and generate a motor operating parameter based on the tracked position of the seed and a target parameter for releasing the seed. The motor of the seeding system is operated based on the motor operating parameter.

Precision agricultural seed delivery system

A first source of an electromagnetic signal is configured to illuminate or radiate the evaluation channel through which a series of particular seeds pass. For example, the electromagnetic signal comprises a pulse with at a primary reference phase and primary reference magnitude. A first receiver of the electromagnetic signal comprises a detector to determine or identify a first seed-related characteristic (e.g., first seed characteristic) based on an observed primary phase and an observed primary magnitude. For instance, a seed treatment device is configured to treat or spray discharged particular seed with a seed treatment based on the estimated characteristic, or to reject non-conforming seeds that do not meet seed specifications.

An agricultural machine includes a metering system comprising one or more meters configured to meter particulate material into a first material distribution line and a second material distribution line, a first sensor configured to generate a first sensor signal indicative of a first measure of a flow of the particulate material in the first material distribution line, a second sensor configured to generate a second sensor signal indicative of a second measure of the flow of the particulate material in the first material distribution line, and a control system. The control system is configured to receive an indication of a sensed flow rate of the particulate material in the second material distribution line, obtain an adjusted flow rate indication by applying, to the sensed flow rate, a rate offset based on the first and second sensor signals, and control the metering system based on the adjusted flow rate indication.

Agricultural seed sensing and control system

A row unit for a seeding machine includes a frame supporting a gauge wheel and a seed meter. A depth stop assembly includes a stop setting an upward travel limit of the gauge wheel with respect to the frame, and a handle that is lockable and releasable to move the stop to select among seeding depths. A downforce actuator is operable to generate downforce to be applied through a gauge wheel arm and the gauge wheel to the soil. A downforce sensor is incorporated into the depth stop assembly and movable therewith. The depth stop assembly includes a multi-piece body having a first piece receiving the handle, and a second piece defining a pivot. The first piece of the multipiece body includes a handle-receiving receptacle portion, a fastening portion for fastening to the second body piece adjacent the pivot, and a portion therebetween forming a housing of the downforce sensor.

An agricultural machine includes a motor configured to drive a seeding system that is, itself, configured to meter and deliver seed from the agricultural machine. The agricultural machine also includes a sensor configured to sense a characteristic of the seeding system and a skip detector component, that receives the sensor signal and detects a seed skip in the seeding system. Based on the detected seed skip, a processing system generates an operating parameter of the motor, and controls the motor based on the operating parameter.

An example agricultural machine comprises a material distribution system that includes a material distribution line configured to convey particulate material to a component. The agricultural machine comprises a sensing system that includes a first sensor configured to generate a first sensor signal indicative of a measure of a flow of the particulate material in the material distribution line, a second sensor configured to generate a second sensor signal indicative of a measure of the flow of the particulate material in the material distribution line, and a correlation generation component configured to receive indications of the first and second sensor signals and to generate a correlation metric that represents a correlation between the first and second sensor signals. In one example, the correlation metric is applied to a sensor signal from a second material distribution line to determine a flow rate in the second material distribution line.

A towed agricultural machine includes a converter, configured to convert a first voltage potential generated by a generator to a second voltage potential. The second voltage potential powers a component of the towed agricultural machine. Further, the towed agricultural machine also includes a switch that senses the absence of the second voltage potential from the converter and switches to powering the subcomponent with a second voltage potential received from a source external to the towed agricultural machine. The second voltage potential output by the converter can also be combined, on a power bus, with the second voltage potential from the external source or another source.
