Step 4:
Step 5:
Determine walking speed
Determine discharge rate
Carry out a trial run with the machine
fueled and the container filled with water.
Operate the spray tube (swing it back
and forth) as it will be during the real run
described below. Determine the
The setting of the metering knob is
calculated as follows:
V (l) x v (m/min) x b(m)

distance walked in one minute.

Also use the trial run to check the
selected working width. In the case of
low-growing crops, the best working
width is 4-5 m. The working width should
be marked with stakes.
Va = Quantity of solution
vb = Walking speed
Vc = Discharge rate
Dividing the distance in meters by the
time in minutes gives you the walking
speed in meters per minute (m/min).
