4.7 REAR SPRING HARROW
The planting unit may be equipped with back seed covering
harrow. Carry out installation (Fig. 36) before using the planting
unit by following the diagram that comes with the machine:
Depending on the type of furrower elements involved, mount the
seed-covering harrow support arm on the following holes (Fig.
36):
D - Disc furrower element (Corex);
E - Suffolk coulter element;
F - disc furrower element (Corex) with wheel
The working pressure of the seed covering harrow
springoperated teeth can be regulated by using the lever (A, Fig.
36). When the arm pins on the two holes are shifted, the clearance
angle of the spring teeth varies (B and C, Fig. 36).

5.0 WORKING
5.1 BEFORE STARTING WORK
Before starting the seeding operation grease all parts indicated
by transfer nr. 13 ('GREASE') at page 33 of this leaflet.
5.2 OPERATION START
Start the tractor and run the system at idle for a few minutes,
bringing constant pressure to the entire circuit in order to avoid
instability of the blower. Bring the blower up to the number of
revolutions that corresponds to the working conditions.
In humid climates, operate the fan with no-load for a few minutes
in order to dry out the tubes.
5.3 PREPARATIONS FOR DISTRIBUTING
Carefully follow the instructions below and perform the opera-
tions in the order they are listed:
- Using the gear lever, put the tractor engine into neutral;
- Brake the tractor and if necessary, secure it with wooden blocks
sized according to the size of the wheels;
- Ensure that no-one can approach the tractor driver's seat;
- From the driver's seat of the tractor, raise the equipment;
- Operate the power take-off or the oleo-dynamic system of the
blower at a defined speed;
- Check that all the drive shafts are properly engaged.
- Carefully check moving parts, driving parts and distribution.
- Regulate the metering mechanism as described in the
preceding chapters;
- Adjust the metering unit according to the distribution table;
Remove and overturn the supporting feet.
- Carry out a seeding trial, as described earlier in chapters 4.2.
- Periodically check the results of working.
For a successful work it is useful to distribution on a small
stretch and check that the product are regularly distributed in
the ground.
- At the end of working, discharge the remaining product through
the doser door.
