Calibrating the Sprayer
Note:
Before you use the sprayer for the first time
or change the nozzles or when the sprayer is out of
adjustment—calibrate the sprayer for ground speed
and flow rate.
Note:
The left and right sprayer boom nozzles are
wide pattern (white) nozzles and the center nozzle is
a narrow pattern (red) nozzle.
Note:
Refer to the chemical product label for
application rate recommendations.
The method to calibrate the sprayer flow involves
g305357
driving a preset distance, recording the time, and then
measuring the amount of liquid applied during that
time.
Calculating the Ground Speed
Operator supplied equipment: Stop watch capable
of measuring ± 1/10 second.
1. Measure and visibly mark a course length used
to calculate the average ground speed. Record
the course length here:
Note:
In this example the course length is 45.7
m (150 ft).
2. Add clean water into the spray tank until it is 1/2
full; refer to
3. Drive the machine to an area far enough away
from the course so that when you are driving
it into the course, the machine travels at the
desired ground speed before reaching the first
marker.
g305644
4. Use a stop watch to measure the time (in
seconds) that it takes the machine to travel the
marked course (45.7 m (150 ft) in this example)
while maintaining the desired ground speed.
Record your course time in the course time
worksheet.
