CALIBRATING THE DRILL TO CHECK THE SOWING
RATE
NOTE:
When new, the Seed Pads may have a white powder (chalk dust) on
them. This is to prevent them from sticking together during manufacturing.
This chalk dust can impede your seeding rate until it has been removed or until it
dissipates. This can be done by hand, or over time by using the seed drill.
By Hand:
This can be achieved by sliding the Seed Pad away from the Housing and
dusted off the powder.
Dissipates:
Simply using the Seed Drill. (The seeding rate will slowly increase as the
chalk dust dissipates. (Usually within the first hour of use.) RE-CALIBRATE.
(1) Prime:
Place seed in the hopper over any 5
adjoining outlets. Rotate the Crank Handle
until a steady flow of seed can be
witnessed falling from the seed outlets.
Set the Gearbox pointer in the appropriate
position for you desired seed sowing rate.
(See Seed Chart under hopper lid.)
(2) Seed Catchment:
Place the Calibration Tray under the 5
appropriate Seed metering Units to catch
the metered seed.
Another method is to pull the black seed
dropper hose off the 5 appropriate Coulter
Tubes and place them in a bag or container.
(3) Seed Metering:
Rotate Crank Handle Clockwise 29
times.
(4) Weigh Seed:
Catch and weigh the total amount metered
through the 5 metering units. (in grams).
NOT
E: Remember “TARE” scales before
weighing; for the weight of the bag or
container.
(5) Conversion:
Divide the weight measured by 3 to
establish kilograms per hectare.
ie:
45 grams / 3 = 15kg/ha
(6) Check:
If above or below the desired rate, make the
necessary adjustment via the Gearbox
Pointer Adjuster.
