back and forth) as for the real run
described below. Determine the
distance walked in one minute.
Also use the trial run to check the
selected working width. The best
working width for low-growing crops is
4–5 m. Mark the working width with
stakes.
Dividing the distance walked in meters
by the time in minutes gives you the
walking speed in meters per minute
(m/min).
Example:
The distance covered in one minute is
10 meters.
Walking speed:
Determining discharge rate
The setting of the metering unit is
calculated as follows:
V
a
= Quantity of solution
v
b
= Walking speed
V
c
= Discharge rate
b = Working width
A = Area
Example:
The values determined above and a
working width of 4 meters require the
following setting on the metering unit:
Hectares (ha) have to be converted into
m
2
(ha x 10,000 = m
2
).
To adjust the required discharge rate
see "Metering Unit".
Valve lever
Solution feed is started and stopped with
the valve lever (1).

N Position B (valve lever horizontal,
down) – closed
Metering knobs
The scope of supply includes metering
knobs which allow a wide range of
different discharge rates.
