5.
Unfold the sprayer over a flat, unobstructed area (i.e. no power lines…etc.).
6.
Ensure all boom-fold operations are functional (place a check mark in boxes in
Figure 6
).
7.
Bring engine to field-operational RPM and record below.
8.
Record the time (seconds) it takes for a full stroke for all boom functions. To ensure
repeatable measurements, take the average of 3 trials.
9.
Not all sprayers will have the functions listed below in
Figure 6
.
Ensure the boom has sufficient travel so it does not contact the ground during
these tests.
