An agricultural product delivery applicator for delivering particulate product to a field. The applicator includes a supply compartment to hold the product, a pneumatic conveying system, a metering system, and a controller. The pneumatic conveying system includes first delivery line operably connected to an airflow source and to the supply compartment, and a second delivery line operably connected to the airflow source and to the supply compartment. The metering system includes a first metering device associated with the first delivery line and a second metering device associate with the second delivery line. The controller controls the air flow source, the first metering device to meter product to result in a first mixed flow of airflow and product for the first delivery line, and the second metering device to meter product with the airflow to result in a second mixed flow of airflow and product for the second delivery line.

An agricultural application implement for delivering particulate product to a field. The implement includes a frame, a bin to hold product, a pneumatic conveying system fixed to the frame, a metering system operably connected between the supply compartment and the pneumatic conveying system, and a bin lift system. The pneumatic conveying system includes an airflow source to provide an airflow, and a delivery line operably connected to the airflow source and to the bin. The delivery line includes a plurality of outlets. The metering system meters product with the airflow to result in a mixed flow of airflow and product for the delivery line. The bin lift system includes hydraulic cylinders coupling the bin to the frame, and a bin lift controller to control the hydraulic cylinders to raise or lower the bin.

An agricultural product application implement includes a system and method for indicating an amount of fluid stored. A pressure transducer installed at the sump of a fluid tank electronically measures and displays a fluid depth. Instrumentation, such as an instrument cluster unit for the implement, is programmed via software to convert the voltage output of the pressure transducer to a volume measurement displayed in the operator's line of sight. Software within the instrument cluster unit for self-calibrating accounts for varying densities of different chemical solutions. The pressure transducer is used in conjunction with a transfer medium to prevent corrosive chemical solutions from contacting the pressure transducer.

A propel system of an agricultural vehicle has an active pump displacement control system for equalizing or balancing pressure output of hydrostatic pumps of a tandem pump propel arrangement. The active pump displacement control system may include a pressure sensor(s) for determining output pressure of hydrostatic pumps and use the output pressure values within a feedback loop to provide coil input values of coils that control displacement of the hydrostatic pumps so that the pressure outputted by the hydrostatic pumps can be equalized in real-time while on the go during use of the agricultural vehicle.

An exhaust after-treatment system has a DEF system with improved DEF purge cycling during which time DEF is returned to a DEF storage tank. The DEF system adapts its methodology based on a condition within the DEF system. A purge valve may be arranged in a doser feed line between a DEF supply module and a DEF doser module. A purging control system may be configured to control the purge valve based on detected states within the DEF system, such as a detected state that corresponds to a plugged DEF doser module. If a plugged doser module is detected, the purge valve may be opened to vent the doser module feed line to atmosphere which allows the DEF to be returned to the DEF storage tank without creating a siphon effect that could draw additional DEF from the DEF storage tank into the supply module.

Instrumentation, such as the instrument cluster unit for the implement, can be programmed via software to convert the voltage output of the pressure transducer to a volume measurement to be displayed in the operator's line of sight. Software may be provided within an instrument cluster unit for self-calibrating to account for varying densities of different chemical solutions. The pressure transducer may be used in conjunction with a transfer medium to prevent corrosive chemical solutions from contacting the pressure transducer.

An agricultural implement for applying an active ingredient to a geographic area includes a chassis, and at least one active ingredient tank. Each active ingredient tank is removably positioned on and carried by the chassis. Each active ingredient tank contains an active ingredient therein which is to be applied to the geographic area. Each active ingredient tank has an identification (ID) tag representing data associated with the active ingredient. An electrical reader carried by the chassis is configured for reading the ID tag and providing an output signal. An electrical processing circuit is coupled with the reader and receives the output signal.

Self-propelled liquid dispensing equipment having ground engaging wheels and an active trailing link suspension system in which either suspension struts or air struts control suspension travel. A liquid pressure transducer is connected to a liquid reservoir to provide a control input that varies the assist given by the suspension struts or air strut in direct proportion to the quantity of liquid. A given suspension travel is maintained regardless of the quantity of liquid carried by the equipment.

An axle assembly for an agricultural vehicle that includes an axle configured to be coupled to a wheel. The axle comprises a body and a first arm extending from the body. The body is configured to be disposed within a frame member of the agricultural vehicle and to contact an inner surface of the frame member. Also, the axle is configured to move within the frame member to adjust a distance between the wheel and the frame member, and the first arm is configured to contact a second arm disposed within the frame member to provide structural support to the axle assembly as the axle moves within the frame member.

An agricultural sprayer for metered application of a liquid includes a chassis, and a carrier tank fixedly mounted to the chassis. The carrier tank is configured for containing a carrier liquid therein. One or more active ingredient tanks are each configured for containing an active ingredient therein. A storage area associated with the chassis is configured for and dedicated to removable storage of each active ingredient tank.

A plugged nozzle monitoring system uses a thermal flow sensor located within a spray nozzle of an agricultural sprayer. The thermal flow sensor is free of moving parts and is made of corrosion-resistant materials. The thermal flow sensor is placed within the fluid flow path through the nozzle and activates an alarm if flow through the nozzle falls below the baseline value.

A boom assembly includes a frame, a boom, a boom stabilization cylinder, and a feedback cylinder. The boom is rotatably mounted to the frame to rotate about a first axis. The boom stabilization cylinder is coupled to the boom to resist rotational deflection of the boom about the first axis. The feedback cylinder is coupled to a counterbalancing weight. The feedback cylinder is hydraulically coupled to the boom stabilization cylinder. Movement of the boom stabilization cylinder to resist deflection of the boom causes corresponding movement of the feedback cylinder to lift the counterbalancing weight.
