4.6 ADJUSTMENTS

4.6.1 FURROW OPENER DEPTH ADJUSTMENT

For the shoots to come up well it is important to place the seed at
the right depth on the seeding bed.
- Loosen the nut (A, Fig. 25) end the knob (B);
- The handle (1, Fig. 25) varies the height of the furrow opener
blade, and so determines the depth of the furrow on which to
place the seed. The graduated indicator serves to adjust all the
furrow openers at the same depth.
The pointer of the adjustment scale is purely progressive; it
does not show a variation in cm on the depth on the seeding.
- Tighten the knob (B, Fig. 25) end the nut (A).
In the beet confi guration check that the equalizer is centred on the
seed planting furrow; if necessary adjust screw (2) in Figure 26.

4.6.2 FURROW OPENER PRESSURE ADJUSTMENT

The sod-breaking by the furrow opener blade is made effi cacious
by the load of the said spring. Different working situation need
different soil compression adjustment; varying the position of the
spring forwards or backwards, greater or lesser penetration pres-
sure is given (3, Fig. 27).
Vary the position of the spring at the base, on the three-holed plate,
when the adjustments are not satisfactory.
In the beet confi guration, the part may be fi tted with a seed-pressing
wheel. Rotate the spring (4, Fig. 28) to change the pressure of
the wheel on the ground. On damp soils exclude the action of the
wheel: lift it and lock it with the split-pin (5, Fig. 28).
