Metering Unit - Stihl SR 430 Instruction Manual

English
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:
10 m = 10 m/min
1 min
11.5 Determining discharge rate
The setting of the metering unit is calculated as
follows:
V (l) x v (m/min) x b(m)
a b
2
A (m )
V = Quantity of solution
a
v = Walking speed
b
V = Discharge rate
c
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:
144 l x 10 (m/min) x 4 m

3600 m
Hectares (ha) have to be converted into m

10,000 = m ).
To adjust the required discharge rate see "Meter‐
ing Unit".
