Basic Calibration Procedure
Gearbox Setting Lever
To set the seed rate at the gearbox, slacken the tri knob (1) by
turning counter-clockwise and push from below into the position
indicated in the Sowing Chart. Retighten the star knob firmly.
When one box is being calibrated, set the other one to zero to
prevent loss of product.
Note that the front most lever (yellow letters on black
background) controls the rear box.
Important
The settings shown in the Sowing Charts (kg/ha) can only
serve as reference values. Deviations may occur caused by
differences in the size, shape, density of the seed/fertilizer and
by the dressing agent.
Therefore prior to any sowing, always
carry out calibration trials to accurately determine the
actual seed rate.
Using the stepless variable speed gearbox, the speed of the
metering shaft and thus the seed rate is set steplessly. The
higher the figure indicated on the scale by the setting lever the
greater the seed rate.
Setting Seeder Shutter Slides
The varying flow properties of seeds require different shutter
slide positions which may be found in the Sowing Chart for the
individual type of seed or fertilizer. This corresponds to one of
the three settings as shown.
Bottom Flap Settings
The various seed sizes require matching bottom flap clearances
below the metering wheel. The adjusting plate allows for 10
different settings. The required position for the seed type may
be found in the Sowing Chart. The control levers are located on
the LH end of the seedbox, (opposite end to the gearbox).
Number “1” corresponds to the minimum (closed) position and
“10” the maximum gap.
