Mechanical Row Marker Automatic Control; Row Marker Disk Adjustment - GASPARDO SP DORADA Manual Del Usuario

3.14.2 MECHANICAL ROW MARKER AUTOMATIC CONTROL

If requested, the Manufacturer may supply a set for converting the
row marker from mechanical to hydraulic. The request must be
accompanied by the description of the type and model of the
seeder possessed. For the conversion all the particulars already
foreseen by the machine are re-used.
The row marker is enabled on the right or left of the tractor with an
automatic control (Fig. 33) triggered by the movement of the tractor
lifter. To do this it is enough to lift and lower the tractor lifter once.
Set up
If the pin (1 fig. 33) does not hook the disk (2) or vice versa it does
not unhook from it, adjust the height of the bars (3). When working,
the ropes must be pulled tight.

3.14.3 ROW MARKER DISK ADJUSTMENT

Attach the disc holding sleeve (1 Fig. 34) 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 2
shown, read the dis-tance (L Fig. 30) at which the disc is to draw
the reference line. Regulate the disc at the correct distance, tilt it
slightly and firmly tighten the nuts (Fig. 35). For normal soils the
correct working position of the disc is that shown in Fig. 36 ref. A;
for strong soils turn it over as shown in ref. B Fig. 36. For distances
not covered by the table, use the following rule:
L = D (N+1) - C
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;
L = 75 (8+1) - 190 = 242,5 cm.
When travelling by road, turn the row-marker discs inwards
towardsthe machine (Fig. 37).
