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: 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 seed firmer for firming seeds deposited in the seed trench to ensure good seed-to-soil contact. A bracket mounts the seed firmer to the row unit frame such that the seed firmer is aligned with the seed trench. The seed firmer includes a resilient insert positioned in the firmer body to stiffen the seed firmer to more resiliently firm the seed into the soil.

Abstract: A row unit for an agricultural planter has features for releasably operably coupling a seed meter of the row unit to a seed deposition apparatus of the row unit such as a seed conveyor, seed tube, or the like. Apparatus may be used for tipping a seed meter of the hopper for disengagement from the seed deposition apparatus, or for biasing the seed deposition apparatus into operative engagement with the seed meter. The row unit includes features such as latches for releasably operably coupling the row unit to crop input and vacuum supply lines. Apparatus may also be used for tipping a seed meter of the hopper for disengagement from the crop input and vacuum supply lines. Systems are used for supplying vacuum and crop inputs to the seed meter via the releasably engageable apparatus.

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: A grinder-filter apparatus for preparing an agricultural sample slurry in one embodiment includes a housing defining a grinding chamber, a rotatable paddle disposed in the chamber, a peripheral grinding ring fixedly mounted in the chamber, and a perforated baseplate inside the grinding ring. The grinding ring includes vertically elongated slots each having portions extending above and below the baseplate. The paddle may be formed of a resiliently deformable material. The rotating paddle mixes water and the sample material which may be soil in one embodiment to form the slurry, and forces the slurry into the slots which is deposited in a collection chamber beneath the baseplate. The slots filter out soil particles exceeding a predetermined maximum size as the slurry flows through the slots to the collection chamber. The grinding chamber includes an openable waste door to flush debris out of the chamber between preparing batches of slurry.
