Air Cart/Seeding Terms and Definitions

Single-Shoot—Describes air stream configuration, not number of products. Single-shoot is used when one common product is being carried and delivered from all tanks or when two compatible products are mixed in the air stream and delivered to a single furrow.

Double-Shoot—Describes independent air streams where two incompatible products cannot be mixed in a common (single-shoot) air stream and must be delivered to the soil separately (seeding and fertilizing in a single pass).

Air Damper (Double-Shoot Plenum)—Adjustable device used to divide and balance air flow between top and bottom air streams (runs).

Agitator Shaft—Rocking shaft above meter that keeps product free flowing.

Meter Cartridge—Product handling device that meters product from tank into primary manifold.

Meter Segment—Individual section of meter cartridge that contains meter roller.

Meter Roller—Fluted part of meter segment that meters product.

Fine Tuning Rings—Plastic ring placed on meter roller to reduce product delivery to primary manifold.

Primary Manifold (Mixing Chamber)—Device where moving air stream combines with metered product.

Half-Width Disconnect—Blocking device that shuts down product flow from a tank. Used for seeding point rows, emptying tanks, or removing meter cartridge without spillage.

GREENSTAR Display—Cab mounted monitoring device.

Control Unit—Cart mounted device containing microprocessor and software that controls display and program settings.

Sensor—Signal device used to detect component speed or product flow.

Remote Switch—Seeding tool mounted device that indicates openers position relative to the ground.

Application Rate—Amount of product delivered to the seedbed.

Auger—Product handling device used to fill and empty tanks.

Variable Rate—A Variable-Rate Drive (VRD) system uses hydraulic motors to turn the seed meters. Various sensors along with data entered into the monitor by the operator determines meter speed required to achieve a chosen rate.

SectionCommand™ —Allows individual control of product flow to each  meter section. Through monitor inputs, meter sections can be turned off to stop product flow to individual towers on the seeding tool. This is helpful when seeding overlapping areas.

Meter Gates—Hydraulically operated door, inside the meter, that blocks product flow to individual delivery tubes.

Auger Flighting—Rotating inner member that moves product.

Gate Detection—Magnets on the back side of the gates are used in close proximity to the gate detection sensors to determine if the gates are open or closed.
