5.2 COUPLING AND ADAPTING THE
CARDAN TRANSMISSION
Once the seed driller is coupled to the tractor, the TRANS-
MISSION MUST BE ADAPTED for the equipment with me-
chanical turbine. In order to do so, it is necessary to:
1-
Dismantle and introduce one end in the PTO and the other
end in the seed driller. Therefore, introduce the cardan
into the threaded shaft in both machines, maintaining
the security plug pressed, release the plug and move the
cardan back until hearing a click sound; this sound means
that the plug is in its corresponding receptacle.
ASSEMBLY HOMOKINETIC TRANSMISSION
CARDAN INTO THE TRACTOR PTO.
ALWAYS HANDLE THE TRANSMISSION WITH
THE ENGINE OFF. ALWAYS WORK WITH THE
TRANSMISSION PROTECTED AND IN GOOD
CONDITIONS. AVOID ANY ROTATION IN THE
TRANSMISSION PROTECTION TUBE BY FIXING
IT WITH THE CHAIN.
2-
Determine the minimum shift length “L” (Fig. 8), By lifting
and lowering the hydraulic lift.
Fig. 8
3-
Cut the plastic and metal surplus parts with the same size
and reassembly the transmission (Fig. 9).

4-
Activate the seed driller lift
and verify that the trans-
mission shift is correct.
5-
Secure the cardan to the
tractor by means of the fi-
xing chain (Fig. 10).
PREVENT THE TRANSMISSION FROM WORKING
IN A VERY STEEP INCLINATION ANGLE (MAX.
35º)
COUPLE THE TRACTOR PTO SMOOTHLY SUD-
DEN ACCELERATION CAN RESULT IN SERIOUS
DAMAGE TO THE SEED DRILLER.
5.3 HYDRAULIC SYSTEM
The machine requires hydraulic connexion for:
• FOLDING AND UNFOLDING THE FOLDABLE PARTS OF THE
SOWING EQUIPMENT. One double discharge
• FOLDING AND UNFOLDING THE TRACK MARKERS: One
double discharge
• LOWERING AND LIFTING THE SOWING EQUIPMENT AND
TRACK ERASER (optional). One double discharge with key
for removing the track eraser.
• HYDRAULIC TURBINE One double discharge
• HYDRAULIC SERVICE BRAKE One simple discharge
Hydraulic circuits can be distinguished by their colours ac-
cording the following chart:
TAP
COLOUR
DESCRIPTION
BLUE
Hydraulic system for trackers
GREEN
Hydraulic system for folding the sowing
equipment.
RED
Hydraulic system for service brake and turbine
(only for versions with hydraulic turbine)
YELLOW
Hydraulic system for lifting the sowing equip-
ment and track erasers.
Two flow regulators (Fig. 11) help the hydraulic folding
and unfolding processes to be carried out smoothly:
Each hydraulic system has one regulator for each
operation, which must be
adjusted according to the
hydraulic flow supplied
by the tractor. It is advisa-
ble to star the operation
with the regulator almost
closed for preventing fast
unfolding that may cause
damage to the seed driller.
