3.7 SEEDER POSITION

It is important to adjust the position of the planting unit correctly on
the supporting equipment when in the fi eld.
Positioning the seeder on the equipment is an extremely
dangerous phase. Proceed with extreme caution and carry
out the operation scrupulously adhering to the instructions
provided.
1) Before positioning the seeder, it is important to place the equi-
pment in the position in which it is to operate.
2) Adjust the points (A, Fig. 38) of the planter so that the seeding
elements are raised by a few centimetres from the ground. This
position is the zero point of the position setting. When you are
in the fi eld, you should lower the planter by adjusting the points
(A, Fig. 38) again until the required planting depth is reached.
ATTENTION
If the operating position of the equipment needs to be changed,
re-position the seeder by proceeding as described earlier in
point 2).
3) Adjust the height of the tractor lifting arms:
a) In the work position, adjust the path of the tractor hoisting arms
to guarantee adequate downward movement of the planting
unit. Otherwise, when hollows are encountered in the seedbed,
seed distribution could be irregular due to the seed planting unit
transmission wheels slipping (planing effect).
b) In the transporting position, adjust the arms so that the seeder
does not, for any reason whatsoever, come into contact with
the ground.

3.7.1 ADJUSTING THE SEEDING DEPTH

To obtain a good level at which sprouts come out, the seed needs
to be placed at the right depth into the seeding bed. The planting
depth is obtained mainly by moving the side adjusters of the pa-
rallelogram (A, Fig. 38).
The graduated indicator (B, Fig. 38) does not show the planting
depth. Its purpose is to position the two arms at the same
height from the ground.
The pressure of the planting devices is also adjusted individually
with the nut (D, Fig. 39) that allows the tension of the spring to
be adjusted. The screw (C) acts as a limit switch for each furrow-
opening element. To obtain regular sowing, calibrate the limit switch
(C) to the same measurement for all furrow-opening elements.

3.7.2 PLANTER WHEEL TRACK ERADICATORS

The wheel track eradicators should be placed on the same line
as the tyres of the planter. To adjust the depth of the wheel track
eradicators, varying the position of pin (A, Fig. 41).
