3.2 OPERATIONAL SAFETY
Guards and safety shields are for your protection. DO NOT operate equipment unless they
are in place.
ALWAYS engage tractor PTO at engine idle.
Disengage tractor PTO and shift into neutral before attempting to start engine.
Read and observe all safety decals on the tractor and spreader.
NEVER allow anyone, other than the operator, within 25' of machine while in operation.
DO NOT stop or start suddenly when going uphill or downhill. Avoid operation on steep
slopes.
Be alert for holes in terrain and other hidden hazards. ALWAYS drive slowly over rough
ground.
Reduce speed on slopes and in sharp turns to prevent tipping or loss of control. Be careful
when changing directions on slopes.
Take all possible precautions when leaving tractor unattended: Disengage PTO, lower
spreader, shift into neutral, set parking brake, stop engine and remove key from ignition.
Front tractor weights or front tire ballast should be used to enhance front-end stability on
small tractors.
Risk of being entangled due to rotary driveshaft connecting
the tractor - machine.
Compression and crushing (being entangled) due to contact
with the stirrer rotating inside the hopper.
Compression and crushing due to presence of motion
distribution chains and pinions.
Any reset operation must be carried out with the tractor engine
off, power take-off disconnected, parking brake on, and start-up
key removed from the panel.
Cuts and abrasions due to contact and handling of blades, discs,
distributors and driving elements during reset operations.
Use shear-proof gloves.

3.2 OPERATIONAL SAFETY (continued)
ATTENTION!
Any maintenance, adjustment and cleaning operation must be carried out with the machine lowered to
the ground (in stable conditions), the tractor engine off, power take-off disconnected, parking brake on,
and start-up key removed from the panel.
Machine start-up and stop controls are those of the pulling tractor; the machine is not equipped with

HAZARDS, PREVENTION AND PROTECTION MEASURES
4. MACHINE DESCRIPTION

4.1 GENERAL DESCRIPTION
The fertilizer spreader with centrifugal distribution is a machine
for agriculture that spreads in the field solid mineral fertilizer in
granular and powder form. It is pulled by and coupled to the tractor
by three points.
The fertilizer spreader consists of:
●A bearing chassis
●One hopper designed to contain the product to be spread
●Distribution components, driving and adjustment components
In the front side, the machine is equipped with a coupling
structure with three coupling points to the tractor.
The hopper in metal sheet has a truncated conical shape.
The fertilizer contained in the hopper goes through the dispenser
and, due to gravity, falls on the distributor - spreader system.
The dispenser is equipped with hydraulic controls to
open and close.
The distribution unit is located in the lower part of the hopper.
The unit consists of:
●Agitator to break up clods
●Adjustable dispenser of the quantity of fertilizer to be used
●One distributor - spreader system, of single disk type
The fertilizer, by gravity, goes through 2 openings on the bottom
of the hopper and falls on the distributor-spreader system.
4. MACHINE DESCRIPTION (continued)
7
4.1 GENERAL DESCRIPTION (continued)
The product is dispensed manually with a lever, by varying the
size of the 2 openings on the bottom of the hopper. The position
of the lever is secured by a locking pin. The lever acts on the
adjusting disk, which allows you to vary the amount of product
released and the portion of land on which you distribute the
fertilizer (right or left of the direction of travel of the tractor).
The distributor-spreader system consists of one horizontal
disk with rotational motion; on the upper surface is a
series of straight radial blades designed to distribute
the product by means of centrifugal force. There are
6 blades, 3 long and 3 short, adjustable in 4 different positions,
to allow an optimal distribution depending on the type of
product and working conditions.
Safety devices are provided to avoid any contact with live parts in
motion and to prevent any projection of material outside the working
area, in detail:
●The driving system is protected by fixed protections;
which always needs to be in place for safety.
●The rotary distribution disk is protected by a metal bar that
prevents accidental contact.
●In the front (tractor side) a vertical fixed protection
in metal sheet prevents any projection of material outside
the working area and always needs to be in place for
safety
