What is Air Delivery ?
A basic air delivery system consists of an air cart, a series of hoses
that form an air distribution system, and a seeding tool. The air cart
has a split tank, a fan and meters to direct the right amount of air
and product into the distribution system. The distribution system uses
primary lines to carry product to the seeding tool, where a header divides
product into smaller, secondary lines directed to openers. The seeding
tool carries trip assemblies, openers and press wheels or harrows.
Three Separate Systems
a Flexi-Coil air cart, you are not limited to one distribution system—up
to three separate systems can be placed on the seeding tool. With one
system you can single-shoot. With two, you can single- or double-shoot.
With three systems, you can single-, double- or triple-shoot.
- Single-Shoot – mixes one or more products together
in a single distribution system, with application in one location.
Most common are the application of seed alone or the application
of a mixture of seed and fertilizer. The application and blending of
two fertilizers while banding is also single-shoot.
- Double-Shoot – applies products separately in two
locations, by adding a second distribution system. A common double-shoot
system applies seed while placing fertilizer below and to the
side of the seed row.
- Triple-Shoot - adds a third distribution system
and requires an air cart with three tanks. A broadcast granular application
along with a double-shoot placement of seed and fertilizer qualifies
as triple-shoot. Flexi-Coil offers a standard integrated third
tank on the 3850 and 4350.
Granular distribution systems provide for the
application of granular product, like alfalfa or chemicals, to the ground
ahead of the tillage tool. To increase accuracy in such applications,
special secondary headers can be used.
- Main tank – As part of a single-
or double-shoot operation, use the main tank to broadcast fine, granular
product. (e.g. applying grass seed alone or granular herbicide while
banding fertilizer.) The Flexi-Coil granular application system comes
with a specialized roller for accurate product metering—right from
the tank on any Flexi-Coil cart.
- Third tank – The third
tank (3850 and 4350 only) uses the cart's fan to accurately deliver fine
products. For example, granular herbicide is broadcast from the third
tank while fertilizer and seed are applied from the main tanks. Power
is delivered to the meter from the air cart ground drive, and the cart's
auger fills and empties the third tank. You can use of half the implement
width for spot application, thanks to a separate clutch and a dual
