Automatic control (Fig. 26);
The automatic control enables the right or left row-markers by
moving the tractor lift.
If, for any reason, you have to operate the hoist without exchanging
the row marking arms, disengage the movement using a cord
hooked to the ring (D Fig. 26), operating from the driver's seat.
Adjustment
If lever (A Fig. 26) either fails to hook onto, or unhook from, pin (B),
adjust the extension (C= ~90 mm).
3.10.2 HYDRAULIC ROW MARKER
The planting unit has a hydraulic row marker control device. The
hydraulic cilinders should be connected by their hydraulic pipes
to the hydraulic distributors of the tractor. Inside the hydraulic
cylinder boss there is a calibrated grub screw that could be
clogged by impurities in the oil. If there is malfunctioning, remove
the nipple and clean the hole of the calibrated grub screw, and
then put everything back paying attention to the direction of insertion
of the grub screw in the boss.
For correct functioning of the row marker arm, couple the
hydraulic tube for connection to the tractor to a dual acting
distributor. When the system is not in use, protect the quick
coupling with its cap.
ATTENTION
Before starting up the row marking hydraulic circuit, using
your hand, apply slight pressure to the row marking arm in the
direction of the arrow (Fig. 28), then unhook the safety devices
on both arms (A Fig. 28).
During road transport, block the safety devices on both row
marking arms (A Fig. 28) in the vertical position.
ATTENTION
Safety measures concerning the hydraulic control:
1) When the hydraulic pipes are connected to the hydraulic
system of the tractor, make sure that the hydraulic systems
of the operating machine and the tractor are not under
pressure.
2) For hydraulic-type functional connections between the
tractor and operating machine, sockets and plugs must be
marked with colors, in order to prevent erroneous use. It
could be dangerous if an exchange should occur.
3) The hydraulic system is under high pressure; because of
accident hazards, when leaking points are looked for,
suitable auxiliary instruments should be used.
The row marker arms have a safety bolt (A Fig. 29) 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.
