SEEDER CALIBRATIONCALIBRATION

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.
