3.13 ADJUSTMENTS

3.13.1 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. 24). The graduated
indicator serves to adjust all the furrow openers at the same
depth. The pointer of the adjustment scale is purely progressi-
ve; it does not show a variation in cm on the depth on the
seeding. In the beet configuration check that the equalizer is
centred on the seed planting furrow; if necessary adjust screw
(1) in Figure 25.

3.13.2 FURROW OPENER PRESSURE ADJUSTMENT

The sod-breaking by the furrow opener blade is made efficacious
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
pressure is given (1 Fig. 26).
Vary the position of the spring at the base, on the three-holed
plate, when the adjustments are not satisfactory.
In the beet configuration, the part may be fitted with a seed-
pressing wheel. Rotate the spring (1 Fig. 27) 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. 27).
