4.2 ROW MARKER DISK ADJUSTMENT
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 the centre of the tractor (L, Fig. 35).
The row marker arms reverse themselves independently and
this reversal is actuate by the comand of the oildynamic
distributors of the tractor.
For a correct working, every flexible connecting pipe, from the
row marker equipment to the tractor, must be engaged to a
simple effect oildynamic distributor.
When the system is not in
use, protect the quick coupling with its cap.
The valve plant is integrated with unidirectional flow regulators
(Fig. 36), which allow to adjust the oil quantity in opening or
closure, in accordance with the direction of their assemblage.
Flow from A to B, free (Fig. 36);
Flow from B to A, choked (regulated) (Fig. 36).

adjustment has been made, re-tighten the lock nut.

not cause the rising or descent speed to damage the structure
itself. Never exceed the maximum admissible pressure for
