3.6 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 seeding depth is adjusted simultaneously for all planting
devices through a crank (A Fig. 33). By rotating it clockwise, a
stronger pressure can be exerted on the planting devices to the
ground by means of the extension springs, thus allowing deeper
seeding. Pressure can also be further adjusted individually at
spring level, by changing the position of the chain rings (B Fig.33).
With disc-type planter shoes, the depth is determined by the
limiter block (A Fig. 34) by changing its position with the lever (B
Fig. 34).
On request, the planting unit can be equipped with hydraulic
regulation of the pressure of the furrow openers (Fig. 35). This
device is fitted in place of the manual adjuster screws (Fig. 33)
and connected through the special hydraulic tubes to the tractor
distributor (double effect). The device is operated by moving the
lever of the tractor distributor. A pointer on the adjustment scale (A
Fig. 35) allows a purely progressive reference to the pressure
value of the furrow opener units:
"0" = minimum pressure;
"8" = maximum pressure.
3.7 HYDRAULIC LIFTING OF THE FURROW OPENER

BEARING FRAME

On request, the planting unit can be equipped with a hydraulic
lifting device (Fig. 36) for the furrow opener bearing frame (9 Fig.
2). This device is fitted in place of the manual adjustment tie rod
(A Fig. 18) and connected through special hydraulic tubes to the
tractor distributor (double effect).
The hydraulic system supplied has a unidirectional flow regulator
(A Fig. 36) that when correctly adjusted allows the furrow opener
bearing frame to be raised parallel to the ground.
Free flow from A to B (Fig. 37);
Throttled flow from B to A (regulated) (Fig. 37).
Slacken the lock nut (1) and turn the knob (2) to adjust. When the
adjustment has been completed, re-tighten the lock nut.
During the planting unit/equipment assembly operations, and
if a hydraulic lifting device is installed for the furrow opener
bearing frame, check that the transmission gears of the
planting unit (Fig. 21) do not, and cannot, interfere with other
parts of the assembly during normal working operations. If
necessary move the gearbox (A Fig. 21) along its support (B).
