Distributor head and tramline system
In the distributor head (Fig. 41/1) the seed is
evenly distributed to all sowing coulters. The
number of distributor heads depends on the ma-
chine's working width. Every individual distributor
head is provided with one charger.
On seed drills with two distributor heads
•
one distributor head provides the sowing
coulters of one machine side with seed.
•
the seed metering of one machine half (part
section) can be switched off. For specific
tramline systems it is necessary to start the
sowing operation at the beginning of the
field with just one half working width (part
section).
The tramline control in the distributor head allows
the creation of tramlines in the field in pre-
selected distances. For setting the individual
distances the relevant tramline rhythms have to
be entered into the AMATRON 3 ./. AMALOG
+
.

When creating tramlines
•
the tramline control on the distributor head
stops the seed flow to the seed tubes (Fig.
42/2) via shutter slides (Fig. 42/1).
•
the tramline coulters do not sow seed into
the soil.
When the electric motor (Fig. 42/3) closes the
relevant seed tubes (Fig. 42/2) in the distributor
head, the seed flow to the tramline coulters is
stopped.
When creating tramlines the tramline counter
shows the figure "0" in the AMATRON 3 / AMA-
LOG
+
. The reduced seed quantity for creating a
tramline can be adjusted.
A sensor (Fig. 42/4) checks the proper function
of the shutter slides (Fig. 42/1), which open and
close the seed tubes (Fig. 42/2).
AMATRON 3 / AMALOG
+
triggers the alarm in
case of faults.
