3.4 MAXIMUM QUANTITY OF PRODUCT DISTRIBUTED
The maximum distributable quantity of product depends on the
width and the working speed. By using the diagrams in figures
17 and 18 it is possible to determine the maximum distributable
quantities.
1) Find the curve that corresponds to the width of the machine.
2) Select the quantity of product to be distributed.
3) Select the working speed.
4) If the intersection point is below the curve, the quantity is
attainable; if it is not, the working speed must be reduced.
Quantities of product that exceed the diagram reading
might not be transported by the blower and so could
cause blockage of the tubes.
3.5 BLOWER
Types of blower drive.
PA1: mechanical, 1000 rpm. (standard).
mechanical, 540 rpm. (optional).
oleo-dynamic dependent. (optional).
PA2: oleo-dynamic dependent. (standard).
oleo-dynamic independent. (optional).
3.4.1 POWER TAKE-OFF RPM
The blower pump is enabled by the tractor power take-off. It is
important that the rpm indicated are respected. If the minimum
rpm is not reached the machine could lose distribution precision
and where there are large quantities of seeds, the granulate
pipes could get clogged.
ATTENTION
Driving a vehicle with a 540 rpm propulsion, with a power
take-off of 1000 rpm and an engine rpm correspondingly
low is not permitted. Danger of blower pump breakage.
During distribution do not let the power take-off rpm
drop too low.

3.5.2 OLEO-DYNAMIC BLOWER DRIVE
Safety
The equipment is suitable only for the use indicated. Any
use other than that described in these instructions can
cause damage to the machine and constitute a serious
danger to the user.
Regular operation depends on the correct use and adequate
maintenance of the equipment. It is advisable therefore to
observe scrupulously what is described in order to prevent any
inconveniences that could prejudicate proper operation and
duration. It is just as important to keep to what is described in
this booklet since the Manufacturer declines all responsibility
due to negligence and non-observance of these rules.
At any rate the Manufacturer is available to assure immediate
and accurate technical assistance and all that may be necessary
for the improved operation and better performance of the
equipment.
The oleo-dynamic blower drive may be used, maintained and
repaired only by personnel with complete knowledge of the
apparatus in question and of the relative dangers. Check the
correct connection of the quick-couplings; failure to do so could
result in damage to the system. Disconnect the oleo-dynamic
unions only after having first depressurized them.

C- manometer;
D- engine;
E- safety valve;
F- quick-coupling scavenge side;
G- cooler (optional).
