THEORY OF OPERATION
Spray fluid is prepared and placed in the tank via the lid opening and strainer basket. Foreign matter is trapped in
the strainer mesh for disposal after the tank has been filled.
When the pump is switched on power is applied to the pump motor from the battery. When the pump operates,
fluid is drawn through the filtered suction line into the pump head.
With each rotation of the pump motor, fluid is forced via valves into a high-pressure chamber in the pump head.
Fluid exits from the chamber via a check valve and passes into the boom or spray nozzle.
OPERATING INSTRUCTIONS (TURFMATE)
Application Rate
Achieving the correct chemical application rate to the turf is only possible when the operator knows:
a)
Nozzle spacing
b) Flow rate per nozzle and
c) Forward speed of sprayer
The above parameters have been used to establish the following Performance Data chart. This chart shows
application rate of spray solution in litres per 1,000 square metres (1196 square yards) and area covered by the
50 litre tank in square metres at each forward speed and nozzle flow rate.

1.
Put water in the tank, switch on pump, and measure the volume of liquid from each nozzle in one minute.
The total volume collected divided by the number of nozzles is the Flow Rate per Nozzle in litres per
minute.
2.
Calculate the forward speed of sprayer by measuring time taken to walk 20 metres:
20 metres in 36 seconds is 2 km/hr
20 metres in 24 seconds is 3 km/hr
20 metres in 18 seconds is 4 km/hr
20 metres in 14.4 seconds is 5 km/hr
3.
Determine application rate of spray solution to turf by using the above chart.
e.g. If the average flow rate is 0.9 litres/minute and the forward speed is 3 km/hour, the application rate is
36 litres per 1,000 square metres. (36 litres per 1,000 square metres is equivalent to 3.6 litres per 100
square metres or 360 litres per hectare).
4.
Determine chemical required per tank by calculating the recommended chemical application rate per
metre then multiplying that figure by the area (in metres) covered per tank as shown in the chart.
e.g. Average nozzle flow rate is 0.9 litres/minute and the forward speed 3 km/hour will result in 1,390
square metres sprayed. If say Banvine is used at 40ml per 100 square metres (0.4 x 1,390ml) or 556ml is
required per tank.
