Abstract: A tool assembly for a planter row unit resides at the forward end of the row unit beneath the tool bar. The assembly includes a bracket assembly connected to the row unit, with a ground engaging tool removably mounted on the bracket assembly for movement between raised and lowered positions. A linear actuator controls the position of the tool. The tool may also include a depth control mechanism. Different tools can be interchanged on the bracket assembly.

Abstract: A seed meter includes a meter housing having a first chamber for seeds and a second chamber. A seed disk is rotatably supported within the meter housing and has a first side and a second side. The first side is exposed to the first chamber and the second side is exposed to the second chamber. The seed disk includes a plurality of seed openings that extend between the first and second sides at a predetermined radial position. A singulator is positioned against the first side of the seed disk and has at least one structure for removing excess seeds from the seed openings as the seed meter disk rotates relative to the singulator. A radial position of the singulator is controlled at least in part by a hub portion of the seed meter. A biasing spring is positioned to exert an axially-oriented bias force pressing the singulator against the first side of the seed meter disk.

Abstract: Described herein are systems, implements, and methods for seed orientation during planting operations of agricultural plants of agricultural fields. In one embodiment, a system for seed orientation includes a seed disk capable of rotation in operation and having at least one singulator to adjust an orientation of seed to a desired seed orientation for placement within a furrow during planting. A vision system in proximity to the seed disk determines seed orientation data for seed on the seed disk.

Abstract: An agricultural vehicle includes a coupling structure for making a tool-less attachment between a first connector piece and a second connector piece. The first connector piece has at least one pin, and the second connector piece has at least one slot adapted to receive the pin in a receiving pocket that is circumferentially spaced from an axially-open inlet portion of the slot. The slot includes an inlet ramp between the slot inlet portion and the receiving pocket, and the inlet ramp is less steeply angled than a second ramp surface that forms a portion of the receiving pocket adjacent the first ramp.

Abstract: A precision seed-distribution system of the type applied on planters with a machine element that touches the soil, a row unit chassis that supports a seed meter, and a seed conductor tube extending downward from the seed meter. The seed conductor tube may have vertical grooves along a length of the seed conductor tube and across an internal surface of at least one sidewall of the seed conductor tube.

Abstract: A seeding apparatus has a frame and a plurality of furrow openers spaced laterally along the implement frame. A like plurality of singulating meters is provided, each mounted on the frame close to a corresponding furrow opener, and seed tubes are configured to receive singulated seeds from a corresponding singulating meter and deposit the seeds in the furrow created by the corresponding furrow opener. A pressurized air stream conveys seeds through each seed tube and a seed supply supplies seeds to each singulating meter. A meter control operates each singulating meter to provide a variable seeding rate that is independent of the seeding rates of the other singulating meters. A seed catching member follows each furrow opener and catches the seeds exiting the seed tubes to maintain a consistent seed spacing in the furrow.
