An agricultural implement configured to be propelled by a prime mover. The implement comprises a toolbar configured to support a plurality of agricultural tools. The toolbar is a front-folding toolbar configured to be shifted forward from an operational position to a transport position. The implement further comprises a draw-bar extending forward from the toolbar and configured to be coupled with the prime mover. The draw-bar is rotatably connected with the toolbar via a connection assembly that presents a generally laterally extending rotational axis, such that the draw-bar is configured to rotate vertically about the rotational axis.

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.

A nutrient placement system may include a plurality of dispensers configured to be supported on a frame of a row unit of an agricultural implement with each of the plurality of dispensers being configured to be positioned at least partially rearward of a respective ground-engaging tool of a plurality of ground-engaging tools of the row unit along a forward direction of travel such that the plurality of dispensers are spaced apart along the forward direction of travel. Each of the plurality of dispensers may be configured to selectively dispense one or more agricultural products onto the field worked by the respective ground-engaging tool. Additionally, the nutrient placement system may include a computing system configured to control operation of the nutrient placement system to selectively dispense the one or more agricultural products from the plurality of dispensers onto the field.

Work machines, fertilizer opener assemblies for work machines, and methods of operating work machines are disclosed. A work machine includes a chassis, a frame, and a fertilizer opener assembly. The frame is coupled to the chassis for movement relative to the chassis. The fertilizer opener assembly is coupled to the frame to selectively form trenches in the soil for the deposition of fertilizer. The fertilizer opener assembly includes an actuator that is extendable and retractable to vary a length of the actuator and a cutting implement coupled to the actuator. Operation of the actuator drives movement of the cutting implement between a cutting position, in which the cutting implement makes contact with the soil to form trenches in the soil, and a transport position, in which the cutting implement is raised above the soil.

A mobile agricultural material application machine includes one or more ground engaging traction elements configured to carry the machine along a travel path, one or more material tanks configured to hold a material, one or more material quantity sensors configured to detect a quantity of the material in the one or more material tanks and generate material quantity sensor data indicative thereof, one or more calibration conditions sensor configured to detect one or more calibration conditions and generate calibration conditions sensor data indicative thereof, and a control system configured to determine conditions are suitable to perform a material application rate calibration operation while the mobile agricultural travels along the travel path based on the calibration conditions sensor data and perform the material application rate calibration operation while the mobile agricultural material application travels along the travel path based on the determination that conditions are suitable to perform the material rate calibration operation.

A scan using a pulsed distance measuring light with two wavelengths of which reflectances are different with respect to a content of a nitrogen by a laser scanner, the two wavelengths are separated, lights are received, a distance measurement value and a light amount are detected for each pulsed distance measuring light and for each of the two wavelengths, a height of a crop is detected based on the distance measurement value, a received light amount ratio of the two wavelengths is detected, and a growth condition of the crop is detected based on the detected height and the received light amount ratio.

The disclosed apparatus, systems and methods relate to fluid distribution systems. The fluid distribution systems being made up of a plurality of positive displacement pumps disposed on a fluid distribution manifold and proximate to the tank and the point of product discharge. The system optionally has a valve system for precision control of fluid discharge.

A metering bank for an air cart. The metering bank includes metering bank frame and a plurality of meter modules disposed laterally adjacent to one another in the metering bank frame. Each of the plurality of meter modules is independently removable from the metering bank in a direction generally parallel with the forward direction of travel of the air cart. Each of the plurality of meter module includes a metering mechanism.

Work machines, fertilizer opener assemblies for work machines, and methods of operating work machines are disclosed herein. A work machine includes a chassis, a frame, and a fertilizer opener assembly. The frame is coupled to the chassis for movement relative thereto. The fertilizer opener assembly is coupled to the frame to selectively form trenches in the soil for the deposition of fertilizer. The fertilizer opener assembly includes an actuator that is extendable and retractable to vary a length of the actuator and a cutting implement coupled to the actuator. Operation of the actuator drives movement of the cutting implement between a cutting position, in which the cutting implement makes contact with the soil to form trenches therein, and a transport position, in which the cutting implement is raised above the soil.

A towable cart (100, 200) for storing granular and/or liquid product, the towable cart (100, 200) including a chassis (300) configured for attachment to a prime mover, the chassis (300) including a plurality of mounting points (310) that provide releasable and reconfigurable attachment of a plurality of product tanks (400).
