A meter assembly for an agricultural machine includes a meter, a conduit, and a bypass. The meter includes a roller to move commodity to the conduit. The bypass is coupled to the conduit and the meter to facilitate air flow therebetween free of interference from the roller or the commodity.

An adjustment mechanism is provided for a multi-row seed planter to provide infinite adjustability of the seed discs to allow precision planting with staggered seed rows. The adjustment mechanism comprises an idler roller on the end of a pivotal arm about which the drive chain is trained. The position of the roller can be adjusted to modify the chain path, and thereby rotate the seed metering sprocket and associated seed disc to a desired angular position before planting begins.

In one aspect, a wheel assembly configured for use with an agricultural implement. The wheel assembly includes a wheel comprising an outer ground-engaging element and an inner hub extending radially inwardly from the outer ground-engaging element. The wheel defines an internal cavity radially inwardly relative to the outer ground-engaging element. The wheel assembly further includes a sensor positioned within the internal cavity of the press wheel.

A sowing heart control apparatus for controlling a sowing heart with a sowing heart monitoring apparatus having an evaluation unit for determining the occupancy of sowing holes of a rotating seed disk with a seed in operation. The evaluation unit delivers an actual value of the occupancy of one or more sowing holes. The sowing heart control apparatus, depending on a deviation of the actual occupancy value from a predetermined setpoint of the occupancy of one or more sowing holes, controlling actuating elements which influence the occupancy. The invention also relates to a sowing heart and a single seed drill.

A delay period timing system for a seeding implement with a feed control. A distribution network conveys products to the furrow openers, and a feeding mechanism controls flow of products into the distribution network. A flow sensor downstream from the feeding mechanism detects when products are flowing at a sensing location, and a timer measures a delay period between the time the feeding mechanism starts or stops flow and when the flow sensor starts or stops detecting flow. The delay period is adjusted to account for the location of the flow sensor. A method of determining the delay period includes determining the length of the distribution network and determining the speed of flow of the products. The system can be used on seeding implement with or without sectional control.

An agricultural air cart assembly includes an agricultural air cart. The agricultural air cart includes independently controllable, first and second product metering systems that regulate the rates at which product flows from a storage compartment into corresponding first and second distribution lines. Independently controllable, rotatable fans are operatively connected to corresponding first and second distribution lines and are configured to generate optimized air flows in the first and second distribution lines which entrain and carry the product downstream toward corresponding row units at balanced pressures.

An inductor box for an agricultural implement includes an inlet configured to receive agricultural product from a tank. The inductor box also includes a housing having a cavity therein. The cavity is configured to receive the agricultural product from the inlet. The inductor box includes a gate configured to be removably inserted between the inlet and the cavity, to block the agricultural product from entering the cavity while disposed between the inlet and the cavity, and to enable the agricultural product to enter the cavity while removed from being disposed between the inlet and the cavity. The inductor box includes a first guide coupled to the housing and configured to direct the gate away from the inlet. The first guide is disposed between the gate and the inlet while the gate is disposed between the inlet and the cavity.

In one aspect, a crop input applicator is provided. In one aspect, the applicator comprises a valve (e.g., voice coil valve) disposed to deposit liquid on or near a seed furrow and/or on or near a seed. In one aspect, the applicator includes one or more seed sensors disposed to detect passage of seeds.

A metering device for dispensing agricultural product from a bin. The metering device comprises a housing enclosing an interior space, and a gate assembly removably received within the interior space of the housing. The gate assembly is configured to guide agricultural product through the housing. The gate assembly comprises a product gate comprising an arcuately-extending gate valve. The product gate at least partially defines a channel within the interior space of the housing through which agricultural product can flow. The gate assembly further comprises a gate key configured to selectively secure the product gate within the housing. Rotation of the gate key is configured to cause a corresponding rotation of the product gate.
