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

7. OPERATION
7.1 FIELD DISTRIBUTION
●Place the tractor at the beginning of the field (Position 1). The distance from the border has to
be the same as the spreading Ref R.
●Move along the field perimeter keeping the R distance from the border as long as you arrive in
the position 2. In this position you have to be at the R distance from the position 1.
●Go along till the position 3.
●Make a 180° turn, place the tractor in position 4 at the R distance from the position 3 and go
along till the position 5.
●Repeat this procedure until you have spread the entire area of the field (positions 6 and 7).
7.2 SPREADING VARIABLES
●The quantity of fertilizer spread depends on the tractor speed, the spreading area, fertilizer type
and humidity, weather conditions and from the adjusting machine.
●Keep the tractor speed constant while working.
●Preserve the fertilizer in a way to keep its features from being altered.
