A spacing adjustment mechanism of a depth gauge wheel assembly of a planting row unit of an agricultural implement includes a rod fixed on one side to a pivot assembly of the planting row unit, and on which a spindle with a threaded external face is mounted, the threaded external face interacts with a threaded inner face of a bearing of a support arm of a gauge wheel.

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 particle delivery system of an agricultural row unit includes a particle belt having a particle engagement section configured to receive a particle from a particle metering and singulation unit and a particle exit section configured to expel the particle toward a trench in soil. The particle delivery system includes an air flow system configured to establish an air flow toward the particle engagement section of the particle belt to accelerate the particle toward the particle belt, such that a particle speed of the particle reaches a target particle speed, is within a target percentage of a belt speed of the particle belt, or both, as the particle reaches the particle engagement section of the particle belt. The air flow toward the particle engagement section is a substantial portion of a total air flow established by the air flow system relative to other sections of the particle belt.

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.
