For machines with twin hopper granulate (e.g.
pesticide, fertiliser) ne grains can be placed in
addition with the micro-granulate facility.
The maximum possible placing quantity is
30 kg/ha at 10 km/h working speed.
The granulate must be more of a granular com-
position. The metering unit is not suitable for
sand or dust like substances.
The micro-granulate is located in a tank inside
the hopper (300 l).
¾ Unlock to open (a) and turn counterclockwise (b).
¾ Turn clockwise to close (c) and lock (a).

Open / close tank (twin hopper version)
The tank must be absolutely leaktight during use!
¾ Always check the cover for leak tightness with
the fan running, after it had been opened.
Micro-granulate is transported to the metering
screw. The required quantity is transported via
the screw and fed to the fan air ow.

Risk of injury on the rotating screw
¾ Switch o the micro-granulate facility before
working on the metering screw.
Depending on the granulate quantity, the meter-
ing unit can be tted with two dierent augers.
The theoretical delivery rate of the augers is
38 cm³ or 66 cm³ per revolution.
The actual displacement depends on various
factors and can therefore only be determined
by calibration.
