4.9.7 FIELD CALIBRATION
To verify the application rates in the field, follow
this procedure:
1. Fill the tank to the neck with water and mark
the level of water.
2. Check that all screens are clean.
3. Set the chemical system pressure to the
desired value and run the tractor at the
selected engine RPM in the selected gear.
4. Drive through the measured distance while
spraying.
5. Refill the tank to the same mark and measure
the amount required.
6. Divide the amount of liquid sprayed by the
area covered to determine the application
rate.
