A singulating meter includes a seed disc with seed apertures rotates in a vertical plane through a seed reservoir. A horizontal seed tube has an inlet adjacent to the top of the seed disc and the seed apertures move along a seed aperture path toward the inlet. Pressurized air flows into the tube inlet, and through each seed aperture as it rotates upward out of the seed reservoir pushing a seed into each seed aperture which seed then moves along the seed aperture path through about 180 degrees of rotation to a release position at the top of the path where the seed is carried horizontally into the seed tube. An ejector pushes debris out of the seed apertures into the seed tube. An alignment guide moves the singulator element of the meter into the operating position where same is magnetically secured.

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 gauge wheel (1) for use in controlling the depth of a furrow formed by at least one planting member of cultivation equipment includes a hub member (5) having a central hub and an outer peripheral portion (9); and a resilient coil member (3). The resilient coil member (3) includes a plurality of coil windings (17) which extend closely adjacent to the outer peripheral portion (9) of the hub member (5) and which define an outer periphery of the gauge wheel (1). The coil member (3) is connected at or adjacent one end thereof to the hub member (5). In use, the resilient coil member engages the soil on a side of the furrow and controls the depth by which the at least one planting member cuts into the soil to form the furrow. There is also provided a coulter gauge wheel which includes a coulter disc and at least one gauge wheel as described above.

An agricultural trench depth sensing system having a trench implement adapted to be disposed in a soil trench opened in a soil surface. In one embodiment an ultrasonic sensor detects a distance to an upper surface of said trench implement or a target disposed thereon. In another embodiment, said trench implement includes one or more fingers which rotate with respect to said trench implement to detect the soil surface relative to said trench implement. In another embodiment, said trench implement includes side sensors for detecting the sidewall of the soil trench.

In one aspect, a system for providing downforce control includes a seeder including a plurality of row units. One or more actuators are operably coupled with the plurality of row units and configured to adjust a downforce of the plurality of row units. A sensor is configured to detect one or more seeding parameters. A computing system is configured to control the operation of the plurality of row units. The computing system is further configured to receive an input associated with a target depth range of the row unit into an underlying field, receive data related to one or more seeding parameters, receive data related to an actual seeding depth; generate a command signal based on a differential between the actual seeding depth and the target depth range; and generate a force command for the one or more actuators to adjust a downforce of the plurality of row units.
