Abstract: A downforce controller for an agricultural implement having a double-acting hydraulic cylinder. The cylinder is configured to be coupled to an agricultural row unit and an agricultural toolbar for transmitting a net downforce between the agricultural toolbar and the agricultural row unit. A first pressure in a first chamber of the cylinder and a second pressure in a second chamber of the cylinder have counteracting effects on the net downforce. A manifold coupled to the cylinder is in fluid communication with the first chamber. A pressure control valve coupled to the manifold is in fluid communication with the manifold and the first chamber.

Abstract: An automated computer-controlled sampling system and related methods for collecting, processing, and analyzing agricultural samples for various chemical properties such as plant available nutrients. The sampling system allows multiple samples to be processed and analyzed for different analytes or chemical properties in a simultaneous concurrent or semi-concurrent manner. Advantageously, the system can process soil samples in the “as collected” condition without drying or grinding. The system generally includes a sample preparation sub-system which receives soil samples collected by a probe collection sub-system and produces a slurry (i.e. mixture of soil, vegetation, and/or manure and water), and a chemical analysis sub-system which processes the prepared slurry samples for quantifying multiple analytes and/or chemical properties of the sample. The sample preparation and chemical analysis sub-systems can be used to analyze soil, vegetation, and/or manure samples.

Abstract: A double diaphragm slurry pump (7080) comprises: a pump body (8200) defining a vertical longitudinal axis (LA) and first (8201) and second (8202) pumping chambers; an inlet flow manifold (8203) and an outlet flow manifold (8204) coupled to the pump body; a first pump head (8230a) coupled to the body adjacent the first pumping chamber, the first pump head comprising a longitudinal flow bore (8231) separate from the first pumping chamber and fluidly coupled to the inlet and outlet flow manifolds, an upper air vent bore (8232), and a lower slurry exchange bore (8233), the upper air vent bore and lower slurry exchange bore each fluidly coupling the longitudinal flow bore in turn to the first pumping chamber; and an operating shaft (8240) coupled to a resiliently deformable diaphragm (8241) disposed in the first pumping chamber; wherein the shaft is moveable in a pump stroke to pump a fluid through the longitudinal bore of the first pump head and the first pumping chamber from the inlet flow manifold to the outlet flow manifold; and wherein the upper air vent bore (8232) is smaller in diameter than the lower slurry exchange bore (8233) such that air is preferentially ejected from the first pumping chamber rather than slurry during the pump stroke.

Abstract: A coulter assembly for collecting soil samples from an agricultural field in one embodiment comprises an annular collection blade configured for penetrating soil to capture a sample, an annular cam ring configured for stationary mounting to a frame of an agricultural vehicle and comprising a cam track, a blade hub coupled to the blade for rotatably supporting the annular collection blade from the annular cam ring, and a movable sample collector mounted to the annular collection blade. The moveable sample collector is configured and operable for extracting a soil sample as the annular collection blade is rotated through the soil. The moveable sample collector in one embodiment comprises a piston mechanism including a cylinder and rod movably disposed therein which actuated by the annular cam ring to alternatingly open and close a collection end of the cylinder as the annular collection blade rotates through the soil.

Abstract: A seed firmer and bracket combination for a planter row unit. The bracket includes a forward configured to mount to a frame member of the planter row unit. A rearward portion extends rearward of the seed tube or seed conveyor. The seed firmer includes a body having an upper portion, a tail portion, and a resilient flexible portion between the upper portion and the tail portion. The upper portion is releasably received in a vertical opening in the bracket such that the resilient flexible portion and tail portion extend downwardly and rearwardly from the bracket. The seed firmer is releasably restrained in the bracket preventing the seed firmer from moving upward, forward, rearward and downward until the upper portion of the seed firmer is disengaged from the bracket.

Abstract: A seed firmer and bracket combination for a planter row unit. The bracket includes a forward end configured to mount to a frame member of the planter row unit. The seed firmer includes a body having an upper portion, a lower portion, and a resiliently flexible central portion. The upper portion of the seed firmer body is releasably retained between a forward surface and a back surface of the rearward end of the bracket by a rearwardly extending upper arm and lower arms that respectively engage a top edge and a bottom edge of the back surface preventing the seed firmer body from moving vertically and horizontally relative to the bracket until the upper arm is disengaged from the top edge of the back surface.
