Abstract: A vehicle includes a frame, a plurality of tanks supported on the frame and housing particulate, an unloading system, a lifting mechanism, and a positioning system. The unloading system includes a plurality of individual carriers, each of which corresponds to one or more of the tanks. Each of the carriers defines a discharge opening for dispensing particulate unloaded from one or more of the tanks. The carriers are mounted to the frame such that the carriers are supported independently of the tanks. The lifting mechanism includes a shiftable positioning rail that at least partially supports each of the carriers, with generally vertical shifting of the positioning rail simultaneously raising or lowering each of the discharge openings. The positioning system includes a plurality of positioning devices, with shifting of each of the positioning devices resulting in fore-and-aft shifting of the corresponding one or more of the discharge openings.

Abstract: An agricultural seeding machine includes a metering system and a damper arrangement. The metering system for the seeding machine includes selectively powered metering sections operable to individually allow or restrict seed dispensation. The damper arrangement is included so that pneumatic conveying of the particulate within the machine is consistently maintained when particulate flow is varied between the metering sections.

Abstract: An agricultural particulate delivery system includes a tank operable to contain particulate, a metering structure including a metering element operable to regulate flow of particulate from the tank, and a collector assembly configured to receive particulate from the metering structure. The collector assembly directs particulate into a particulate-transporting line configured to deliver particulate toward an implement. The system also includes a sensor located between the metering element and the particulate-transporting line and that is configured to detect particulate flow from the metering element to the particulate-transporting line.

Abstract: A double shoot seed and fertilizer placement unit has a leading shank that cuts a fertilizer trench in the soil, a seed shovel immediately behind but above the lower extremity of the shank to cut one or more seed shelves in the soil above and outboard of the fertilizer trench, a boot behind the shovel that places seeds on the shelf and then drops fertilizer into the fertilizer trench between and below the seeds, and a fertilizer guide member that rides in the fertilizer trench below the fertilizer outlet to maintain the integrity of the trench in preparation for the fertilizer and helps guide the fertilizer down to the bottom of the trench as it emanates from the boot.

Abstract: A static hydraulic system provides yieldable hold-down force to the ground-engaging tools of an implement when the system is in its hold-down mode. Alternatively, the system can be operated in a way to lift the tools into an elevated ground-clearing position when placed in the lifting mode. An accumulator and pressure-reducing valve are incorporated into the hydraulic circuit in such a way that the system need not be an active hydraulic system in which a pump on the tractor would continuously circulate pressurized fluid in the system during ground-engaging operations in the hold-down mode.

Abstract: The primary distribution hoses on the tillage implement of a pneumatic seeding machine are of different lengths as needed to reach distribution heads or splitters on the implement that further divide the primary streams of materials into individual streams leading directly to the ground-engaging openers of the implement. Notwithstanding the differential in hose length, outlet pressures at the distribution heads are made uniform through the provision of internal flow restrictors associated with those hoses that are shorter than the longest hoses on the machine. Throat diameters of the restrictors vary in accordance with the pressure drop that is needed to match the difference in hose length between the longest hose and the restricted hose. In a preferred embodiment, the restrictors are mounted within nipples on the coupling assembly that releasably connects conduits from a seed cart with the primary hoses on the implement.

Abstract: A coulter assembly has a resilient spring tine that bears against the compression face of the angled coulter during field operations to remove dirt clumps that otherwise inhibit the furrow-forming action of the coulter. A special spring coil mounting of the tine provides a lively vibratory action as the tine encounters various impact loads from different directions during field operations, thus rendering the tine essentially self-cleaning insofar as trash accumulations are concerned. The angle of attack of the tine relative to the ground and the coulter can be readily adjusted without diminishing the vibratory action of the tine.
