Deep Banding
Changing from conventional planting to
deep banding can be as simple as using
the handles on the rear of the meterbox to
rotate the position of the diverter blade. For
example, where all product may have been
conveyed down 3 of 6 primary tubes for
conventional planting, this is now altered by
sending one product down the same 3
tubes and a second product down 3
different primary tubes.
The distribution system will need to have
been set-up to run the dual hoses and
heads required for deep banding. Refer to
Fig. M11 for one possible configuration of
the meterbox.
Triple Shooting
To run a triple shoot system it will be
necessary to have a specific distribution
set-up that will allow the placement of the
three separate products all the way through
to the implement. This can be performed
by using a deep banding sowing boot on
the tines and fitting a urea spreader kit to
the front of the implement.
The meterbox will also need some
adjustment to separate materials from the 3
bins. By diverting the product from some
meterwheels to specific primary conveying
tubes we can ensure that the correct
product is sent to the specific areas on the
implement (refer Fig. M12). Refer to page
108 for details on removing meterwheels
and fitting cover plates.
Partial Diversion
It is also possible to mix some product
(fertilizer) with the seed or another fertilizer
while metering. The diverter blades can be
partially moved and held in position by
using the detent on the plate under the
diverter handle.
The detent plate has 2 positions for
partial diversion. The 2 detents will divert
approximately 33% or 66% of the product
from one meterwheel to an adjacent primary
tube. The operator should check the exact
percentage of product diverted during the
calibration process. The percentage can be
affected by product type and application rate.
Fig. M10 Diverter blade and detent plate.
To determine the total diversion of product to
the different primary tubes you will need to
calculate the percentage of the combined
meterwheel output.
Example
A detent handle for one meterwheel has
been moved to the first position (refer figure
M10 above). This means that approximately
33% of one meterwheels output will be
placed with the adjacent meterwheels total
output. To calculate the total material
placement for the 2 primary tubes you will
need to perform a simple calculation.
(33% + 100%) / 2 = 66% of total product
down one primary tube and 66% / 2 = 33% of
the remaining product down the second
primary tube.
