Distribution head
Depending on the design one or two distributor
towers for seed distribution are attached to the
rear on the seed bar.
On the PPF-design the solid fertiliser distributor
is mounted inside the rear hopper.
In the G+F variant the fertiliser is fed into one
or two distributor towers together with the seed,
depending on design and working width.
All distributor components must be
leak tight. Even slightest leaks and air
losses will cause uneven distribution.
Seed distributor with valves for tram line control and
sensors for seed flow monitoring
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.
If the tram line distribution box is equipped with
a track width change-over, the track width must
only be changed when the valves are open.
This can be checked on the terminal (no tram
line must be switched) or by checking the marks
on the valves.
Seed flow monitoring
The seed flow sensors enable the monitoring of
up to 120 seed and fertiliser hoses.
The sensors are connected in series and the
numbers inform about the order.
In cases of an alarm, these sensor numbers help
when troubleshooting the hoses.
If the monitored hoses are also fitted with valves
for the tram line control, these numbers must
also be entered in a list in the menu for tram line
rhythm - see DrillManager instructions.
Maintenance and inspections
¾
The distribution head must regularly be
checked for foreign matter. Unscrew the dis-
tributor cover and check the outlets.
¾
Check all components and connections regu-
larly for leaks.
¾
Check the function and position of the tram
line valves.
¾
Check the correct order of the seed flow sensors.
