Abstract: A splitter divides an air/product mixture flow, delivered thereto in an air-powered distribution line, between a primary and a secondary distribution channel, which may be flow-coupled to a product hopper or a hose flow-coupled to another product hopper or another splitter. The air/product mixture enters the inlet of the splitter along a first flow path and exits a primary outlet, flow-coupled to the primary distribution channel, along a second flow path generally in-line with the first flow path. Air/product flow is exhausted by a secondary outlet, which is flow-coupled to the secondary distribution channel, at a sideward flow path relative to the first and second flow paths. The velocity flow vector along which the air/product mixture is exhausted from the secondary outlet is at an angle perpendicular to the velocity flow vector along which the air/product mixture is received by the inlet of the splitter.

Abstract: A down pressure adjustment assembly for a disc opener of an agricultural implement includes a rockshaft to which one or more disc opener units are mounted and an actuator that rotates the rockshaft. Rotation of the rockshaft causes the disc opener units to be raised or lowered. When the disc opener units are lowered into a field engagement position, further rotation of the rockshaft will cause compression of down pressure springs for each of the disc opener units.

Abstract: A planting unit for depositing fertilizer and seed in a single pass, double shoot manner includes a rotating disc that cuts a furrow in a planting surface and a trailing seed boot, having a cutting edge, that cuts a vertically and horizontally offset trench in the furrow to form a seed bed in the planting surface. The disc has a mounting frame for mounting the disc to a linkage assembly that is, in turn, coupled to a toolbar mount. The seed boot is also attached to the mounting frame. This common attachment provides a relatively short and compact device without sacrificing fertilizer and seed stratification.

Abstract: A disc hub assembly includes a shouldered spindle that is secured to a disc opener frame and to which a depth adjustment arm and a gauge wheel arm are connected. The disc hub, to which a ground opener disc is mounted, is disposed on the spindle in a manner that allows the disc to rotate around the spindle. A gauge wheel is connected to the gauge wheel arm. When the depth adjustment arm is rotated between depth setting positions the gauge wheel arm is also rotated. As the gauge wheel is connected to the gauge wheel arm, rotation of the gauge wheel arm causes rotation of the gauge wheel. The depth adjustment arm is spring biased into engagement with an arc of notches on the disc opener frame. The notches define a range of positions at which the depth adjustment arm may be positioned.

Abstract: A disc gang for use with an agricultural implement includes a pair of front and a pair of rear disc openers mounted to a carrier boom by a mounting arm that can be independently raised and lowered as desired. The front and rear disc openers are mounted such that the openers can oscillate in response to surface undulations independently of one another. Moreover, the disc openers of each pair are free to oscillate in response to surface contours independently of one another.

Abstract: The present invention provides a method and apparatus to improve seed distribution to a plurality of seed or row units of an agricultural planter. Each row unit is fitted with a seed box having an air/seed inlet and an air outlet through which air is allowed to escape. The present invention effectively closes off or substantially reduces the flow of air out of one or more of the seed boxes to reduce the amount of seed that is fed to the seed boxes. Through the use of restrictor plates, which may be vented to allow some air flow or solid to prevent air flow, the delivery of seed to the seed boxes can be equalized to provide more uniform seed distribution to the row units.

Abstract: An opener for depositing fertilizer and seed in a single pass, double-shoot manner includes a rotating disc that cuts a furrow in a planting surface, a fertilizer tube that drops fertilizer into the furrow, and a trailing seed tube assembly, having a cutting edge, that cuts a vertically and horizontally offset trench in the furrow to form a seed bed in the planting surface onto which seed is deposited. The seed trench provides a seed bed that is offset from the bottom of the furrow to provide horizontal and vertical stratification of the seed and fertilizer.

Abstract: An agricultural implement has a marker assembly that is pivotable in a generally rearward direction when the marker assembly collides with a relatively massive field obstruction. The interconnection of the marker assembly to a central frame of the implement allows the aforementioned pivoting to reduce damage to the central frame and/or the marker assembly during such collisions.
