3.4.5 SOWING DEPTH ADJUSTMENT

Good sprouting requires the seed to be sown at the right depth in
the seedbed. Coulters that work in the tracks of the seeder or
the tractor should be set to greater pressure.
Hoe coulter, disc coulter
The seeding depth is adjusted simultaneously for all planting
devices through a crank (Fig. 15). By rotating it counterclockwise,
a stronger pressure can be exerted on the planting devices to the
ground by means of the extension springs, thus allowing deeper
seeding.
You can further adjust the pressure, separately, changing the
position of the tie-rod (B Fig. 15).
OPTIONAL: The depth is determined by changing the position of
the limiter block (C, Fig. 15), only with hoe coulters (furrow
openers). IMPORTANT: for seeding in moist soils, to a advanced
depth to 5 cm, it is advised to remove the limiter.
In the external rows raise or lower the pressure by adjusting the
screw (A Fig. 16) and locking it with the nut (B).
In the outer furrowing parts, which work on the tracks of the seed
drill wheels, adjust the working depth by changing the position of
the limiting device (C, Fig. 16).
Disc coulter (COREX)
With disc coulters is possible to assemble a rear rubber wheel
(Fig. 17), which allows to check the seeding depht. Thanks to a
series of holes, you can set the same seeding depht for all the
coulter elements (Fig. 17).
A) minimum depht: 0 ÷ 0,5 cm
B) maximum depht: 8 cm
IMPORTANT: we advise against the use of the rear wheel on
moist soils.
Silgle disc coulter
The depth is determined by changing the position of the limiter
block (Fig. 18), only with single-disc coulters (furrow openers).
IMPORTANT: for seeding in moist soils, to a advanced depth to
5 cm, it is advised to remove the limiter (Fig. 19).
