3.7.4 FRONT CLOD CLEARER

The action of the front clod clearer is crucial to correct and homo-
geneous sowing; it allows the track of the element's depth wheels
(1, Fig. 28) to be cleared of the largest clods (H, Fig. 32) 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 see-
dbed.
- 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 agro-
nomic 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. 32), 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. 33).
- Once the best position of the clod clearer has been determined,
set the other seeding elements to this position, using as refe-
rence 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.

3.7.5 PLANTING UNIT EXCLUSION

Switch off the tractor and remove the ignition key.
Raise the single seeder from the ground as follows:
- Fit the spring as shown in position «9a» (Fig. 34).
- Lift the planting unit using the lever (10, Fig. 34).
- Press and hold down the sleeve (11, Fig. 35) in the direction
indicated by the arrow, push forward while turning the ring nut
(12, Fig. 35) until the iron pin comes free.
- Pull the sleeve back as far as it will go (11, Fig. 35).
- To render the drive operative again, push the sleeve forward
and lock the ring nut again against the iron pin.
- Fit the spring as shown in position «9b» (Fig. 34) to lower the
planting unit to the production position. Then, lift the planting
unit to disable the block by means of the supplied lever (10 in
Fig. 34).
IMPORTANT!
Pay the greatest attention to the couplings of the cardan shafts
(A, Fig. 35) and follow the position of the crosses.

3.7.6 PLANTING UNIT TRANSMISSION

Each case is equipped with a safety pin which breaks (13, Fig. 35)
when the rotating of the seeder plate is forced or jams as a result
of foreign bodies entering the distributor (paper, string etc.) Should
this occur, pour the seeds out of the container, check and clean the
distributor, check the plate pegs and replace the safety pin.
WARNING! Do not over-tighten the screws holding the case (14
Fig. 35). It should be able to oscillate.
