4.8.3 ROW MARKER DISK ADJUSTMENT
Attach the disc holding sleeve (1, Fig. 44) onto the two arms of
the row marker, without over-tightening the nuts, insert the disc
and secure it in place by means of the snap pin. Using the
Table 5
shown, read the dis-tance (L, Fig. 40) at which the disc is to draw
the reference line.
Regulate the disc at the correct distance, tilt it slightly and fi rmly
tighten the nuts (Fig. 45).
For normal soils the correct working position of the disc is that
shown in Fig. 46 ref. A; for strong soils turn it over as shown in
ref. B Fig. 46.
For distances not covered by the table, use the following rule:
L = D (N+1) - C
2
where:
L= the distance between the outer most unit and the row marker.
D= the distance between the rows.
N= the number of units operating.
C= the tractorís front wheelbase
Example:
D = 75 cm;
N = 8 units;
C = 190 cm.
L = 75 (8+1) - 190 = 242,5 cm.

WARNING
