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. The handle varies the height of
the furrow opener blade, and so determines the depth of the furrow
on which to place the seed (1, Fig. 25). 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. In the
beet confi guration check that the equalizer is centred on the seed
planting furrow; if necessary adjust screw (1) 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 (1, 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 (1, 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 (2, Fig. 28).
