An agricultural planter includes systems, methods, and apparatuses for maintaining down force pressure at row units of the planter. The row units may include an electric linear actuator connected to linkages of the row units to maintain a down force pressure for the row unit. The linkage may also be removed and replaced with a strut or like mechanism to apply a direct down force pressure to components of the row unit. One or more sensors can be included to obtain information related to the ground to automatically adjust the amount of down force provided based upon a ground characteristic in order to maintain a substantially uniform furrow depth.

The invention relates to a soil cultivation arrangement (100), in particular a soil preparation arrangement, for the agricultural cultivation of a soil (500), in particular a field and/or arable land, with a carrier device for attaching to an agricultural tractor and with one or more soil cultivation units (200, 201, 202, 203) for preparing and/or generating a seed furrow (530), which soil cultivation units (200, 201, 202, 203) as modular components of the soil cultivation arrangement (100) can be connected to the carrier device as required and can be arranged along the carrier device in the desired sequence. At least one soil cultivation unit (200) has a runner-like sliding device (400), the underside of which, as sliding surface (410) facing the soil (500), is designed to slide on a soil surface (510).

An agricultural implement has (i) an elongated open channel member; and (ii) a connecting assembly comprising a first vertical connector plate positioned against a first vertical side of the open member and a second vertical connector plate positioned against a second vertical side of the open member. When the open member twists about a longitudinal axis, its upper and lower flanges will move within upper and lower channels about upper and lower raised surface areas. A clamping assembly includes: a first clamping member extending horizontally between the first vertical plate and the second vertical plate positioned over and proximate an upper surface of the upper flange; a second clamping member extending over and proximate a lower surface of the lower flange; and a third clamping member extending (i) over and proximate a lower surface of the lower flange or (ii) over and proximate an upper surface of the upper flange. A support frame has at least one forward central wheeled support unit connected to the support frame, having at least one first middle wheel operable to freely rotate 360 degrees about a first steering axis. At least one forward outward wheeled support unit is also connected to the support frame and generally transversely aligned with and transversely spaced from the central wheeled support unit, and comprises a restricted rotation caster wheel operable to rotate about a second steering axis only in an outward angular direction from a straightforward direction.

A system to meter multiple agricultural products according to an independently prescribed rate for each in a variable-ratio blend of the agricultural products from a single opener in a plurality of such systems and openers across an applicator such as a drill. Bulk storage compartments associated with the applicator deliver multiple agricultural products to metering assemblies mounted in clusters or pods across the applicator. The agricultural products are fed from the metering assemblies, via a flow re-director, into a manifold, and then into a corresponding single opener having conduits to transport the agricultural product into the soil. Controllers independently regulate metering by the metering assemblies. The flow re-director and manifold provide blending of combinations of the agricultural products for each opener according to a field prescription.

A soil apparatus (e.g., a knife) to engage in soil is described herein. In one embodiment, the soil apparatus includes a soil engaging portion to engage with soil and a plurality of sensors disposed in the soil apparatus. Each sensor is independently pivotable to independently position for sensing soil characteristics of soil.

A sowing coulter for direct and/or mulch sowing includes a coulter body, a tear-open chisel fastened by a fastening device, and coulter blades laterally projecting from the tear-open chisel and provided with front cutting edges, which are arranged in order to create a sowing furrow in the ground. In order to change the penetration depth of the sowing coulter into the ground, the coulter blades are adjustable about a horizontal axis that extends transversely to the direction of travel, and that is fixable in different positions by way of an adjustment device arranged between the tear-open chisel and the coulter body.

Seed sowing apparatus comprising: a frame defining a leading part supporting a soil opening stage and a trailing part supporting a soil closing stage trailing the soil opening stage, wherein the soil opening stage comprises a plurality of laterally spaced seeding units, each seeding unit comprising a soil opening member associated with a respective seed delivery outlet connected to a seed source, wherein each seeding unit is configured to form a respective seeded trench in the ground when the apparatus is in use driven through soil in a forward direction of travel; wherein the soil closing stage comprises a plurality of laterally spaced soil deflection members each associated with a respective one of the seeding units, each soil deflection member being spaced laterally from the soil opening member of its respective seeding unit and configured to deflect soil toward the seeded trench formed by the seeding unit.

An agricultural machine includes a main frame, an adjustable frame coupled to the main frame and, a row unit which includes a linking arm coupled to the adjustable frame, and an actuator coupled to the main frame and the adjustable frame. The agricultural machine also includes a controller configured to command the actuator to move to various positions based on signals received from one or more sensors. The one or more sensors are configured to measure one more indicators associated with an actual height of the row unit relative to ground.
