5.0 LIQUID SYSTEM OPERATION
5.1 SYSTEM FLOW DESCRIPTION
The metering pump, ground driven by the metering wheel, draws liquid fertilizer
first through the flow valve, then the main filter. The liquid fertilizer is then pumped
to the distribution system. A gauge indicates the operating pressure.
Select the appropriate VR nozzle to adjust the liquid fertilizer delivery pressure.
The restriction created by the orifice sets the amount of back pressure required for
even distribution of liquid fertilizer to each opener. Too low pressure will result in
poor liquid distribution and excessive pressure can damage the pump, hoses,
fittings and/or drives.
NOTE: Operating pressure cannot be used as a means of system calibration
as system pressure has no direct correlation to the quantity of product
applied.
Even distribution of liquid fertilizer requires that the operating pressure be
set in the recommended range.
5.2 CHECKING FERTILIZER RUNS
Perform the following test to ensure that each fertilizer run is functioning properly:
1. Ensure that tank is at least partially filled with either water or liquid fertilizer.
2. Proceed forward about 20 - 30 ft (6 - 9 m) running liquid system.
3. Stop tractor and look at ground behind each opener to ensure liquid fertilizer is
discharged behind each run. See www.spraytarget.com
for more information.
5.3 VARIABLE RATE LIQUID CHART
NOTE: Above charts are for reference only, pressures may vary without
affecting the application rate.
