5.8 Blower
fan
The blower fan (Fig. 44/1) generates the air cur-
rent that carries the seed to the seeding coulters.
The hydraulic motor (Fig. 44/2) drives the blower
fan.
The control terminal displays the current fan
speed and issues an alarm if there is a deviation
from the nominal speed. The percent deviation at
which the alarm should be triggered can be
adjusted (see "ISOBUS Software" operating
manual).

The suction guard screen prevents the suction of
straw residues into the blower fan under very dry
conditions.
