An agricultural tractor mounting assembly comprising a toolbar engaged with a first implement engaging a soil subsurface and also equipped with a carrying tool for engaging another implement. The carrying tool may include hydraulic cylinders and hydraulic charged accumulators which lift, suspend, and support implements behind a toolbar engaged to a tractor. The implement engaging the soil and the carrier tool may be engaged to the toolbar of the tractor mounting assembly which is engaged to the tractor.

An illustrative modular smart implement for precision agriculture includes a chassis having a hydraulic system, a control system, and articulating tool arms that are adapted to releasably receive one of a tool attachment for working a crop and/or field, including precision planting, cultivating, thinning, spraying, harvesting, and/or data collection. A toolbar fixed to the chassis receives and supports the articulating tools arms. An alignment member and side shift actuator provide movement of a portion of the tool arms along an axis parallel to a longitudinal axis of the toolbar, and a lift actuator provide movement along a vertical axis.

A work vehicle includes a link mechanism to be equipped with a work implement, a drive mechanism to drive the link mechanism to ascend and descend the work implement, and a control lever is to be operated to ascend and descend the work implement. The work vehicle includes a first displacement transmission mechanism, an additional operational mechanism, and a second displacement transmission mechanism. The first displacement transmission mechanism links the drive mechanism and the control lever to transmit a displacement of the control lever to the drive mechanism. The additional operational mechanism is configured to operate the control lever at a location apart from a position of the control lever. The second displacement transmission mechanism mechanically links the additional operational mechanism and the control lever without interposing the first displacement transmission mechanism to shift the control lever in accordance with an operation of the additional operational mechanism.

An agricultural implement includes a transversely extending frame forming at least a first frame section, a second frame section, and a third frame section, where the first frame section is disposed between the second and third frame sections. A pair of elongated gang assemblies are on the first frame section, an elongated gang assembly is on the second frame section, and an elongated gang assembly is on the third frame section. Each of the gang assemblies is horizontally adjustable relative to the frame. An actuator for each gang assembly operably controls the angular adjustment of the gang assemblies, and a fluid source supplies fluid to the actuators. The actuator on the second frame section is a master actuator for one of the actuators on the first frame section, and the actuator on the third frame section is a master actuator for the other actuator on the first frame section.

A system for limiting plugging within an agricultural implement. The system includes a ground engaging tool configured to be supported by the agricultural implement. An actuator is coupled to the ground engaging tool. The actuator is operable to apply a down pressure on the ground engaging tool. A soil moisture sensor is positioned forward of the ground engaging tool. The soil moisture sensor is configured to measure a soil moisture forward of the ground engaging tool. A controller is communicatively coupled to the soil moisture sensor. The controller is configured to receive, from the soil moisture sensor, a signal that corresponds to the soil moisture forward of the ground engaging tool. The controller is further configured to adjust the down pressure on the ground engaging tool applied by the actuator based at least in part on the signal from the soil moisture sensor.

An implement includes a mechanical coupling component configured to removably couple the implement to a support machine, a hydraulic fluid supply line configured to receive a supply flow of hydraulic fluid under pressure from a hydraulic system associated with the support machine, and a hydraulically-powered component configured to be actuated using the hydraulic fluid. The implement also includes a hydraulic fluid recovery system comprising a hydraulic fluid return line configured to fluidically couple to the hydraulic system associated with the support machine and provide a return flow of hydraulic fluid to the hydraulic system. A hydraulic fluid reservoir is configured to, when the hydraulic fluid return line is decoupled from the hydraulic system associated with the support machine, receive a portion of the hydraulic fluid from the hydraulic fluid return line when a fluid pressure in the hydraulic fluid return line increases to a pressure threshold.

A header assembly for an agricultural harvesting machine comprises a first frame assembly, a second frame assembly that supports a cutter, and is movable relative to the first frame assembly, a float cylinder coupled between the first frame assembly and the second frame assembly, an accumulator, a controllable reservoir, and fluidic circuitry. The fluidic circuitry comprises a first conduit forming a first fluid path that provides a flow of pressurized fluid under pressure to the float cylinder, so the float cylinder exerts a float force on the second frame assembly, a valve mechanism that is actuatable to inhibit fluid flow along the first fluid path between the accumulator and the float cylinder, a second conduit forming a second fluid path fluidically coupled to the controllable reservoir, the controllable reservoir being controllable to add fluid to the float cylinder.
