IMPORTANT:
MAKE SURE THAT THE TURBINE
ROTATES AT THE SAME OPERATIONAL SPEED
BEFORE THE TRANSMISSION WHEEL STARTS
ROTATING. WHEN STOP SOWING, DO NOT
LESSEN THE TURBINE ROTATIONAL SPEED UN-
TIL DETACHING THE TRANSMISSION WHEEL.
7.1 WITH MECHANICAL DRIVE TUR-
BINE
To guarantee the seed supply to the sowing shoes, it is indis-
pensable that the turbine rotates between 4200 and 4500
rpm; to do so, it is necessary to increase the tractor outlet
PTO up to a rotation speed of 1000 m. At lower speed, it is
possible that some seeds remain inside the hoses, clogging
them.
Fig. 61
IF THE SEED DRILLER IS DRAGGED ON THE
GROUND WITH THE AIR TURBINE UPWARDS,
THE SEEDS GOING OUT FROM THE DISPENSER
WILL CLOG THE COLLECTOR HOSE THAT FEEDS
THE VENTURI INJECTOR. IN THAT CASE, TAKE
THE COLLECTOR OUT AND REMOVE THE SEED
BEFORE RESTARTING THE SEED DRILLER.
THE ROTATION OF THE TRANSMISSION WHEEL
WITHOUT THE TURBINE IN OPERATION MAY
RESULT IN OVERFLOWING COLLECTOR HOSES.

CONNECTION
Connect the small hose quick coupling of the turbine to a
tractor pressure outlet. Connect the small hose of 1/2" with
the large quick coupling to a return without pressure.
MAXIMUM RETURN PRESSURE IS 1.5 BAR. EX-
CEEDING THIS PRESSURE MAY RESULT IN EN-
GINE DAMAGE.

ADJUSTMENT
Turbine rotation speed is controlled by adjusting the tractor
hydraulic outlet.
To guaranty the seed supply to the sowing shoes, it is indis-
pensable that the turbine rotates between 4200 and 4500
rpm according to the previous chart. At lower speed, it is
possible that some seeds remain inside the hoses, clogging
them.
IF OIL GETS TOO HOT BECAUSE THE FLOW
PUMPED BY THE TRACTOR IS EXCESSIVE OR
THE OIL RESERVOIR IS TOO SMALL, AN ADDI-
TIONAL OIL RESERVOIR IS NECESSARY.
IF THE TRACTOR HYDRAULIC PUMP FLOW IS
NOT SUFFICIENT FOR FEEDING THE TURBINE
ENGINE OR FOR STARTING ANOTHER NECES-
SARY ELEMENT, PLACING AN AUXILIARY EQUI-
PMENT WITH AN ADDITIONAL PUMP ACTIVA-
TED BY THE PTO AND A REFRIGERATED OIL
DEPOSIT WILL NECESSARY. CONSULT THE MA-
NUFACTURER REGARDING THE SEED DRILLER
OPERATION.
