Abstract: An agricultural implement system includes a down force cylinder configured to apply a downward force to a row unit, and a depth control cylinder configured to vary a penetration depth of a ground engaging tool of the row unit. The agricultural implement system also includes a valve assembly in fluid communication with the down force cylinder and the depth control cylinder. The valve assembly is configured to automatically adjust the downward force by varying fluid pressure within the down force cylinder based on fluid pressure within the depth control cylinder.

Abstract: The present invention is directed to a twin-row planter with tandem driven seed meters at a pair of row units at each row segment of a twin-row planter. A tandem drive system drives the seed meters in a tandem manner, which may include a single transmission assembly simultaneously rotating a pair of seed discs in the pair of seed meters at each row segment. An indexing system allows for quickly changing an amount of relative rotational or angular indexing of seed disks inside of the pair of seed meters at the pair of row units of each row segment to adjust longitudinal spacing between delivery locations of seeds from the seed disks at planted row segments of a planted twin-row. Adjustments can be made at disk hubs, between shaft segments linking the seed disks, or with multiple sets of mounting holds on the seed disks.

Abstract: A seed meter is provided for planting multiple types of seed and rapidly switching between the types being planted in a single planting pass of a planting session of row-crop planting. The seed meter has a split seed meter reservoir with a pair of seed meter chambers flanked by or next to a pair of seed disks. Activation and deactivation of the seed disks within the seed meter are synchronized to selectively deliver one type of seed from one of the seed meter chambers for delivery out of a single seed tube of the seed meter, which may provide absolute and instantaneous on-the-go seed switching within a single row from each seed meter.

Abstract: A seed meter is provided for planting multiple types of seed and rapidly switching between the types being planted in a single planting pass of a planting session of row-crop planting. The seed meter has a segmented seed meter reservoir with multiple seed meter chambers arranged between two pairs of seed disks that may be better parallel to each other or angled with respect to each other to define an X-shaped arrangement of the seed disks in the seed meter. Activation and deactivation of the seed disks within the seed meter are synchronized to selectively deliver a single one of the multiple types of seed from the respective seed meter chamber for delivery out of a single seed tube of the seed meter, which may provide absolute and instantaneous on-the-go seed switching within a single row from each seed meter.

Abstract: A planter includes seed meters with accelerator wheel systems. Each accelerator wheel system receives singulated seeds from a respective seed meter and spaces the seeds with respect to each other to correct timing and thus spacing anomalies of seeds being released from seed disks of the seed meters at incorrect seed disk release events. Each accelerator wheel system adjusts and to adjust the velocity of the seeds to correspond to planter travel speed for releasing the seeds to drop straight down onto the field, without a horizontal velocity. Seeds are rotationally redirected from a generally downward delivery direction from a seed disk to a generally horizontal delivery direction out of the accelerator wheel system, opposite the tractor and implement travel direction.

Abstract: A system is provided for planting multiple types of seed and automatically switching between the varieties during planting in a single planting pass of a planting session of row-crop planting an agricultural field. The system may include a selector assembly arranged between a multi-compartment on-row hopper and a seed meter at each row unit of a planter. A control system controls selector valves of the selector assembly to switch from releasing of seeds of a first type from the on-row hopper the seed meter to releasing of seeds of a second type from the on-row hopper to the seed meter for providing a switchover of seeds being planted from the seed meter, from the first to the second type when the seed meter cross a boundary between different zones of the agricultural field.

Abstract: A system for planting multiple types of seed and automatically switching between the varieties during planting in a single planting pass of a planting session of row-crop or other planting of an agricultural field. The system may include a bulk storage system, an on-row storage system, and a charging system that selectively delivers seeds of different varieties from the bulk storage system to the on-row storage system. The system may include a seed metering system that can be controlled at each of multiple row units to selectively plant different types or varieties of seed based on seed type or variety zones agricultural field, which may correspond to field characteristics defined in a seed variety prescription map.

Abstract: A system is provided for use with a seed-delivering agricultural implement that can use look-ahead predictions and controls to coordinate seed type delivery switchover in a manner that minimizes mixing different seed types during the switchover. The system can include a control system that uses a prescription map to look ahead to coordinate out-of-implement or to-ground seed type delivery switch-over events of seeding and/or planting implements with the implements crossing boundaries between different variety zones of an agricultural field.

Abstract: The present invention is directed to a twin-row planter with tandem driven seed meters at a pair of row units at each row segment of a twin-row planter. A tandem drive system drives the seed meters in a tandem manner, which may include a single transmission assembly simultaneously rotating a pair of seed discs in the pair of seed meters at each row segment. An indexing system allows for quickly changing an amount of relative rotational or angular indexing of seed disks inside of the pair of seed meters at the pair of row units of each row segment to adjust longitudinal spacing between delivery locations of seeds from the seed disks at planted row segments of a planted twin-row. Adjustments can be made at disk hubs, between shaft segments linking the seed disks, or with multiple sets of mounting holds on the seed disks.

Abstract: A seed delivery system is provided that includes a row crop seed planter having a seed meter that can pneumatically deliver seeds to the agricultural field at a rearward velocity that matches a forward velocity of the planter. The seed meter may include a positive pressure source that pressurizes the seed meter and creates an airflow out of a seed tube of the seed meter that carries the individual seeds out of the seed tube at a rearward velocity that is automatically adjusted to match a forward velocity of the seed planter and tractor.

Abstract: A system for planting multiple types of seed and automatically switching between the varieties during planting in a single planting pass of a planting session of row-crop planting of an agricultural field while controlling seed delivery speed to mitigate seed bounce and/or provide desired seed spacing distances. The system may include a bulk storage system, an on-row storage system, and a charging system that selectively delivers seeds of different varieties from the bulk storage system to the on-row storage system and a seed delivery speed control system that regulates seed delivery speed.

Abstract: The present invention is directed to a planter with seed meters with accelerator wheel systems. Each accelerator wheel system receives singulated seeds from a respective seed meter and spaces the seeds with respect to each other to correct timing and thus spacing anomalies of seeds being released from seed disks of the seed meters at incorrect seed disk release events and to adjust the velocity of the seeds to correspond to planter travel speed for releasing the seeds to drop straight down onto the field, without a horizontal velocity. Spacing and timing is also improved by reducing delivery variation typically attributable to bounce down a seed tube by instead smoothly rotationally redirecting seeds from a generally downward delivery direction from a seed disk to a generally horizontal delivery direction out of the accelerator wheel system, opposite the tractor and implement travel direction.
