The distributors for seed and fertiliser are mount-
ed in the middle of the drill.
They distribute and direct both seed and fertiliser
to the coulters.
All distributor components must be leak tight.
Even slightest leaks and air losses will cause
uneven distribution.

Valves for tram line control
The distributor is equipped with valves for the
tram line control.
The arrangement depends on the working width,
the tram line rhythm, the track width of the spray-
ing and spreading machine and the number of
valves per track.
The valve function can be checked by examin-
ing the air flow on the seed coulters or the seed
placement on the surface.
The valves have a small identification mark on
the underside of the shaft, which shows the
position of the valves.
This enables checking the rotary motion of the
valve and its end position.
