Fan speeds
The required fan speed differs in dependence
on the towed machine and the working width.
In addition, the required speed is influenced by
the design of the pneumatic system, hopper,
fan size as well as seed and fertiliser quantity.
Travel speed, weight and shape of fertiliser
and other factors also have an influence on the
required air quantity.
The values in the table must only be consid-
ered of being guide values. The actual rotary
speed may differ from the specification by up
to 500 rpm.
NOTE
¾
Always determine the correct speed by field
tests or during a test placement.
For uniform transverse distribution you should
always aim at the highest possible speed,
whereby the seed or fertiliser should not be
blown out of the seed bed.
