4.6 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. 32).
The row marker arms reverse themselves independently and
this reversal is actuate by the comand of the oildynamic
distributors of the tractor.
When the system is not in use, protect the quick coupling with its
cap.
System regulation
The valve plant is integrated with unidirectional flow regulators
(Fig. 33), 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. 33);
Flow from B to A, choked (regulated) (Fig. 33).
o regulate, loosen the lock nut (1) and turn the knob (2). Once this
adjustment has been made, re-tighten the lock nut.
WARNING
Make sure that the result of this adjustment does not cause
the rising or descent speed to damage the structure itself.
Never exceed the maximum admissible pressure for the
hydraulic system.
4.6.1 ROW MARKER ARM ADJUSTMENT
See Fig. 22 and observe the following rules for correct row market
arm adjustment:
L = D (N +1)
2
where:
L= the distance between the outermost element and the row
marker;
D= the distance between the rows;
N= the number of elements working;
Example:
D= 12,5 cm (inch. 5); N= 40 elements.
L = 12,5 (40 + 1) = 256 cm
2
During operation, keep the stop block in position (C, Fig. 34), in
order to enable the row marker arm to follow the movement of the
ground. Before reclosing the equipment ready for transportation,
lock the row marker arm by rotating the stop block to position (D).
The row marker arms have a safety bolt (A Fig. 39) so that the
planter unit structure will not be damaged. If they happen to bump
into an obstacle, this bolt will break and so the row marker arm
will rotate to leave the equipment structure intact.
Replace the safety bolt with the bolt supplied (B, Fig. 35).
