Seeder Position; Adjusting The Seeding Depth - Gaspardo PA2 Use And Maintenance

USE AND MAINTENANCE
4.5 SEEDER POSITION (CENTAURO)
It is important to adjust the position of the planting unit correctly
on the supporting equipment when in the field.
A
The working depth of the machine is determined by the position
of the levelling rollers (see the Rotating Harrow Operation and
Maintenance manual).

4.5.1 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 pressure of furrower and the seeding depth may be regulated
B
by a centralized hydraulic control (Fig. 39). During operation, the
pressure of the furrower can be increased in areas in which the
fig. 39
ground presents more resistance to penetration.
During operation, the pressure of the furrower can be increased
in areas in which the ground presents more resistance to
E
penetration.
The blocks (det. A-B, Fig. 39) are used to identify the maximum
and minimum planting pressure respectively that can be applied
_
on the furrowers and act as end-of-travel pieces for the hydraulic
cylinder.

You can further adjust the pressure, separately, changing the
position of the tie-rod (C, Fig. 40).
With suffolk coulters only a spring (det. E, Fig. 40) is supplied, as
an accessory, to reset the weight of each individual spring
C
element (D) when the spring is fully unloaded. Shallow seeding

is possible in this condition.

Disc coulter
With disc coulters is possible to assemble a rear rubber wheel
(Fig. 41), which allows to check the seeding depht. Thanks to a
series of holes, you can set the same seeding depht for all the
coulter elements.
IMPORTANT: we advise against the use of the rear wheel on
moist soils.
Silgle disc coulter
The depth is determined by changing the position of the limiter
block (F, Fig. 42), only with single-disc coulters (furrow openers).
IMPORTANT: for seeding in moist soils, to a advanced depth to
5 cm, it is advised to remove the limiter (G, Fig. 42).
