3.7 DEPOSITION OF THE SEED

3.7.1 PLANTING UNIT

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. 28) using the crank (2 Fig. 28). A numbered scale (3 Fig.
28) enables all of the parts to be adjusted to the same degree.
N.B.: the pointer of the adjustment scale is purely progressive;
it does not show a variation in cm on the height of the side
wheels.

3.7.2 REAR COVERING WHEELS

The rear set-up of the seeding elements is of considerable
importance in quality sowing.
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 29;
- using the handle (4 Fig. 28), adjust the pressure of the rear
inclined wheels for closing and packing the seed furrow.

3.7.3 FRONT CLOD CLEARER

The action of the front clod clearer is crucial to correct and
homogeneous sowing; it allows the track of the element's depth
wheels (1, Fig. 28) to be cleared of the largest clods (A, Fig. 30)
that could cause irregular planting depth.
IMPORTANT!
- Use the front clod clearer only where there are large clods.
- The use of the clod clearer must not create dips in the
seedbed.
- Not suitable for sowing on stony ground.

ADJUSTMENT

- Identify a particularly cloddy area of the ground to be sown.
- Put the seed drill in its average working conditions with seed
and fertilizer hoppers half full.
- Set the planting depth (see chapter 3.7.1) according to the
agronomic choices dictated by the seed to be distributed.
- Fully raise all the front clod clearers.
- With the tractor's power take-off disconnected and the seed
drill on the ground in its working position, move over the cloddy
area for 4 to 5 metres.
- On the outer element only, lower the front clod clearer to 3 to 4
cm from the level created by the depth wheels of the seeding
element (Fig. 30), and the front earth-opening blade to approx.
2 to 3 cm from the wing of the clod clearer.
- Move for a short stretch with the seed drill and check the
behaviour of the clod clearer and the whole seeding element.
- If the ground is compact, facilitate the penetration of the
element's furrow opener discs by giving greater depth to the
front earth-opening blade of the clod clearer (Fig. 31).
- Once the best position of the clod clearer has been determined,
set the other seeding elements to this position, using as
reference the notches marked on the individual elements of the
clod clearer.
Changing from one type of ground to another entails adjustment
of the clod clearer's position.
