7.7 Working width / scatter tables
The PS 120/200/300/500 M1, PS 500 M2 can be used for a maximum working width
of up to 6m (with electric fan) and up to 12 m with the HG 300 M1 (hydraulic fan).
The spreading quantity depends on the speed of the sowing wheel and the driving
speed during sensor operation. To determine the required sowing volume, you
should calibrate the seed rate before commencing work.
The seed tables show you the sowing volumes for the individual seed types in
kilograms per minute (= sowing volume of calibration test for seed rate).
NOTE: These tables can be used as benchmarks but cannot be applied equally
in all circumstances because many factors play a role and significant changes
can arise (e.g.: thousand-seed weight, dampness of the seed, changes in flow
characteristics, and much more).
The sowing volume is determined according to the following formula:
