SEEDER CALIBRATION
CALIBRATION
IT IS THE RESPONSIBILITY OF THE OPERATOR TO ENSURE THAT
EACH BATCH OF SEED IS PROPERLY CALIBRATED IN THE SEEDER
PRIOR TO APPLICATION. FAILURE TO DO SO MAY RESULT IN
INADEQUATE OR EXCESSIVE SEED RATES. AFTER PROPER
CALIBRATION, IN ADDITION TO USING CONSISTENT SEED, THE
CHOSEN GAUGE SETTING AND GROUND SPEED MUST BE
MAINTAINED TO OBTAIN THE CALIBRATED RATE.
THE SEEDING RATE CHART PROVIDED IS TO SERVE ONLY AS INITIAL SETTING
GUIDE.
I. GENERAL OBSERVATIONS
Each product flows differently requiring calibration for each product. Variations in formulations,
seed size, humidity, temperature and age of product may affect application rates.
The applicator depends on gravity flow of the product particles through precisely adjusted
openings at each tube spout. The ground or electric driven rotor assures a constant flow when
turning and interrupts the flow when it stops, allowing only the particles in the rotor segment
exposed to the openings to flow out.
To close the hopper bottom openings, rotate the shut off lever counter-clockwise until the slide
stop contacts the hopper stop. To open the hopper bottom openings, rotate the lever clockwise
until the slide gauge cam contacts the hopper stop. The opening increases as the cam is rotated
from 0 to 80.
