4.8 ROW MARKER

fi g. 40
The row marker is a device which tracers reference line on the
ground parallel to the direction of the tractor. When the tractor will
have fi nished its run and inverted its course, it will proceed with
C
one of the front wheels on the reference line (Fig. 40). At each
new passing the seeder will trace a reference line on the opposite
side of the previous one. Row marker arm inversion is activated by
the tractor'shydraulic distributor control. If requested it's possible
to convert the row marker from hydraulic to mechanical.

4.8.1 HYDRAULIC ROW MARKER

The planting unit has a hydraulic row marker control device. The
plungers should be connected by their hydraulic pipes to the ancil-
lary hydraulic distributors of the tractor. Inside the hydraulic cylinder
boss there is a calibrated grub screw that could be clogged by im-
purities in the oil. If there is malfunctioning, remove the nipple and
L D D D
clean the hole of the calibrated grub screw, and then put everything
back paying attention to the direction of insertion of the grub screw
fi g. 41
in the boss. On request, the hydraulic row marker device can be
fi tted with a valve that alternately operates the two arms.
In this case just one hydraulic tractor distributor is suffi cient. When
the system is not in use, protect the quick coupling with its cap.
(Fig. 41).
System regulation:
The hydraulic systems provided come equipped with one-way fl ow
regulators (Fig. 42) which allow for the regulation of the quantity
of oil during opening or closing, depending on how the regulators
have been installed:
Flow from A to B, free;
Flow from B to A, choked (regulated).
o regulate, loosen the lock nut (1) and turn the knob (2). Once this
adjustment has been made, re-tighten the lock nut.
WARNING
fi g. 42
Make sure that the result of this adjustment does not cause the
rising or descent speed to damage the structure itself. Never
A
exceed the maximum admissible pressure for the hydraulic
system.

4.8.2 MECHANICAL ROW MARKER AUTOMATIC CONTROL

B
If requested, the Manufacturer may supply a set for converting
the row marker from mechanical to hydraulic. The request must
2
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.
43) triggered by the movement of the tractor lifter. To do this it is
fi g. 43
1
enough to lift and lower the tractor lifter once.

Set up

If the pin (1, fi g. 43) 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.
