3.8 ROW MARKER

The row marker is a machine that traces a reference line parallel
to the tracks of the tractor on the ground.
Once the tractor has completed its run and it has turned around,
follow the reference row with one of the front wheels (L1, Fig. 36)
or with the centre of the tractor (L2, Fig. 36) according to the row
marker employed,
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.
Each time it passes, the seeder will mark a reference line on the
side opposite to the previous passage. Row-marker arm
inversion is activated by the tractor's hydraulic distributor control.
The hydraulic row marker device has a valve that alternately
operates the two arms, so that just one hydraulic tractor distributor
is present.
When the system is not in use protect the quick couplings with
the hoods provided and house the hydraulic pipes in the support
provided for the purpose.
System regulation
The hydraulic systems provided come equipped with one-way
flow regulators (Fig. 37) which allow for the regulation of the
quantity of oil during opening or closing, depending on how the
regulators have been installed.
1) Regulator for closing the row marker;
2) Regulator for opening the row marker.
- Flow from A to B, free;
- Flow from B to A, choked (regulated).
Calibration of the flow regulators:
- Slacken the lock nut (C Fig. 37).
- Fully close the oil flow (CLOSED).
- Using the hydraulic distributor of the tractor, operate the system
and open the oil flow by turning the knob (D Fig. 37).
- When finished making the adjustment, tighten the lock nut again.
- Carry out the calibration on all four regulators.
Make sure that the result of this adjustment does not cause
the rising or descent speed to damage the structure itself.
For normal soils the correct working position of the disc is that
shown in Fig. 38 ref. A; for strong soils turn it over as shown in ref.
B Fig. 38.
During travel by road, lock the row marker arms in a vertical
position with the safety bolts (C Fig. 41) and turn the discs to
come within the machine's overall dimensions (D Fig. 41)
locking them with the bolts supplied.
Before travelling on the road, with row marker arm for track at
the tractor centre, rotate the upper arm (E) as shown in figure
41.
