DuoDrill
The Pronto DC can be additionally equipped
with a DuoDrill.
This allows the simultaneous drilling of main
crops and catch crops.
This facility consists of a seed hopper (capacity
300 litres), a pneumatic system with hydraulic
fan, injector sluice and distributor tower. Placing
takes place via a seed bar with baffle plates.
Control takes place via the E-Manager.

Seed hopper
¾
Always keep the seed hopper closed while
drilling to prevent dust deposits.
Dust causes malfunctions, increased wear
inside the metering unit and can lead to a
reduction of the seed quantity.
Fall sluice
In the fall sluice the seed is injected into the
air flow from the fan. During calibration seed is
taken from the bottom opening.
¾
Always keep the calibration opening closed.
Pneumatic system
¾
Ensure leak tightness of the pneumatic sys-
tem.
All hoses and components must be leak tight
and firmly attached.
Pressure losses compromise distribution.
¾
Check the distributor regularly for soiling and
deposits and clean it.
Tram line valves can be installed, if necessary.
Fan
The hydraulic fan is directly driven by the tractor
hydraulics.
The generated air flow conveys the seed from
the fall sluice to the seed pipes. The required
volume flow rate depends on:
•
Type and weight of the seed
•
Placing quantity
•
Working width
•
Working speed
¾
Determine the correct fan speed in the field.
¾
Do not choose the speed too low to prevent
blockage of the pneumatic system and to
achieve good transverse distribution.
¾
Do not choose the speed too high to prevent
seed from being blown from the placement
area.
¾
Depending on working width and seed, a fan
speed of approx. 2000 - 3000 rpm is recom-
mended for uniform transverse distribution.
NOTE
¾
Check the fan settings, seed transport and
seed placement at the start of work and then
regularly during working.
¾
Adjust the fan speed, if necessary.
