4.6.2 PLANTING UNIT «MARISA»
In order to ensure that the seeds are all planted at a uniform depth,
a few simple adjustments should be made to the planting unit.
Adjust the seeding depth by changing the height of the side wheels
(1, Fig. 46) using the crank (2, Fig. 46). A numbered scale (3, Fig.
46) enables all of the parts to be adjusted to the same degree.
N.B.: the pointer of the adjustment scale is purely progres-
sive; it does not show a variation in cm on the height of the
side wheels.
REAR COVERING WHEELS
The rear set-up of the seeding elements is of considerable impor-
tance in quality sowing (Fig. 47):
A) Rubber «V» shaped (1 inch) press wheels;
B) Rubber «V» shaped (2 inch) press wheels;
C) Iron «V» shaped press wheels.
These elements are crucial to the covering of the seeds after they
have been sown.
They should therefore be suitably adjusted according to the type
of seed and type of ground:
- change the position of the rear wheels on their support as shown
in the diagram in Figure 48 (D-E);
- using the handle (4, Fig. 46), adjust the pressure of the rear
inclined wheels for closing and packing the seed furrow (5, Fig.
46).
If the covering wheels («NO», Fig. 48) are not aligned with the
seed furrow, proceed as follows:
- Raise the planting unit.
- Loosen the clamping screw (6, Fig. 48).
- Rotate the cam (7, Fig. 48) by 180° in a clockwise direction to
move the covering wheels to the right, and in an anticlockwise
direction to move them to the left.
- Visually centre the wheels with the furrow opening disc of the
seeding element.
NOTE: After centring the covering wheels, ensure that the wheels
are all resting on the ground at the same time («SI», Fig.
48) and with the same pressure.
- After completing the adjustments, tighten the clamping screw.
SOIL SCRAPER DISC FURROWERS
Planting units are supplied with soil scrapers in production confi -
guration (F, Fig. 49) which adhere to the disc furrowers.
The soil scrapers are enabled or disabled by turning the supplied
screw (8) as follows:
F) soil scrapers enabled;
G) soil scrapers disabled.
