4.9 NOZZLE DELIVERY RATES
To use the Nozzle Delivery Rate Charts:
NOTE: The three charts provide information in the following measurement formats:
Section 4.9.1 - Imperial gallons per acre - All Nozzles
Section 4.9.2 - US gallons per acre - All Nozzles
Section 4.9.3 - Liters per hectare - All Nozzles
1. Examine the chemical label to determine the desired application rate.
2. Look up the desired tractor speed in the top row of the chart and the desired pressure in the second column
(second or third columns of the metric chart).
3. Find the desired application rate for this combination of ground speed and pressure.
4. Use the corresponding nozzle tip size (01 to 04) and strainer size shown in the leftmost column.
NOTES:
The rates in the tables apply to all types of spray tips. XR and ER series tips can be operated efficiently from 100
to 400 kPa (15 to 60 psi).For standard tips, maintain at least 200 kPa (30 psi) to achieve a uniform spray pattern.
The rates in the tables are based on 50 cm (20") nozzle spacing. See Section 4.11 for information about working
with nozzle spacing other than 50 cm (20").
The rates in the table are based on spraying water. See Section 4.8 for information about adjusting for the effect of
a solution density heavier or lighter than water.
AI TeeJet tips have good patterns between and 690 kPa (40 and 100 psi). Optimum pressures are between 400
and 550 kPa (60 and 80 psi).
DR COMBO-JET tips have a good pattern between 205 and 690 kPa (30 and 100 psi).
Optimum pressures are between 275 and 550 kPa (40 and 80 psi).
If your sprayer is equipped with an Auto-Rate Control System, be sure to adjust the high and low pressure alarm
set points to match your nozzles. Refer to your Auto-Rate Controller Operator’s Manual for more information.

IMPORTANT: When using the sprayer to apply liquid fertilizer, because of the high weight of the fertilizer
(approx. 13 lbs/Imp. gallon), the tank MUST NOT be filled to more than 80% of the tank’s
capacity. This measurement calculates to 4850 Litres (1065 Imp. gallons, 1280 US gallons).
Failure to follow this procedure could result in severe damage to the sprayer.
