4.15 Distributor head and tramline system
In the distributor head the seed is evenly distributed to
all sowing coulters. The number of distributor heads
depends on the machine'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 opera-
tion 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
.

When creating tramlines
• the tramline control on the distributor head stops
the seed flow to the seed tubes (Fig. 74/2) via
shutter slides (Fig. 74/1).
• the tramline coulters do not sow seed into the soil.
When the electric motor (Fig. 74/3) closes the relevant
seed tubes (Fig. 74/2) 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 . The reduced
seed quantity for creating a tramline can be adjusted.
A sensor (Fig. 74/4) checks the proper function of the
shutter slides (Fig. 74/1), which open and close the
seed tubes (Fig. 74/2).
triggers the alarm in case of faults.
