3.5 PREPARATIONS FOR COMBINED SEED/
FERTILIZER DISTRIBUTION
The dosing devices for combined seed/fertilizer distribution have
double chambers made in stainless steel (Fig. 25). Unlike the seed
dosing roller, the fertilizer dosing roller is one with even pitch set
on a hexagonal axis. The mobile bottom of the fertilizer distributor
(A, Fig. 25) consists of a stainless steel door that can be taken off
by means of a stop (B, Fig. 25) to facilitate cleaning operations.
CAUTION! The fertilizer is distributed in the same furrow as
the seed: USE A SUITABLE PRODUCT.
3.5.1 COMBINED DISTRIBUTION HOPPER
The COMBINED distribution hopper is divided into two com-
partments (Fig. 26): the rear one (A) for the seeds and the front
one (B) for the fertilizer. The fertilizer compartment is also fi tted
with a grille to sift any foreign bodies and lumps that could damage
the dosing mechanism. Each compartment has its own controls for
the adjustment of seed and fertilizer distribution rates.
3.5.2 COMBINED DOSING
In combined distribution, fertilizer dosing is carried out through the
gearbox situated to the left of the machine (3, Fig. 3), by moving the
gearbox lever along the plate numbered from 0 to 55 and fi xing it
on the number selected beforehand according to the FERTILIZER
DISTRIBUTION TABLE (Cod. G19707690) on page 51.
We recommend carrying out a fertilizer dosing test following the
same procedure carried out for the seeds (chapter 3.5.3).
3.5.3 FERTILIZER DISTRIBUTION TEST
During the sowing test, pay attention to the points at which
there are parts in movement: agitator shaft, dosing rollers, etc..
For precise fertilizer distribution it is advisable to carry out a dosing
test with the machine stopped.
1) Adjust the gearbox according to the quantities to be distribu-
ted (from «0» to «55»), given in the TABLE OF FERTILIZER
DISTRIBUTION (Cod. 19707690).
2) Extract the lock pin (A, Fig. 21) and, using the handles, move
the seed colletors support in the direction of the arrow.
3) Unhook the collecting trays (Fig. 22) and place them under
the fertilizer discharge.
4) Fill the fertilizer hopper to half load.
5) Insert the handle (Fig. 23) in the gearbox shaft (3, Fig. 3) and
turn it clockwise.
6) Before starting the test, turn the handle a few times to load the
fertilizer distributors, and then empty the collecting trays.
7) Turn the handle for the number of gearbox turns given in table
FERTILIZER HANDLE TURNS (Cod. 19707510) for the type
of planting unit and tyres being used.
