machine is connected.
A different use, like the above mentioned one is considered improper.
Any arbitrary modification made to this machine relieve the manufacturer from any responsibility for
damages or lesions, also serious, that can be caused to the operators, to third parties or to things.
2.2.1.. NAME PLATE
On the hopper of every machine, a name plate is fixed showing the model, the number of series and
the year of construction of the machine.
When some spare parts are required, it is always necessary to refer to the type of machine, to the
serial number and to the manufacturing year.
Location of the name plate on the machine
2.2.2. CHARACTERISTICS OF THE MACHINE
The great spreading precision of these kind of fertlizer spreaders lets them to be used in different
applications, both for specific cultivations and in golf courses.
The Cosmo series of pendular spreaders can rely on a huge range of models adaptable with tractors
of any power.
The upper parts of the gear box are made in polyethylene in order to increase its long life to the
corrosion.
The standard spout allows to get a spreading width from 8 m to 14 m that can be modified according
to the needs and the type of fertilizer used.
The gear box can be set to 3 reduction spreading patterns (see par. 5.1.1) by turning the width
adjustment key.

Pendular Spreader PDV-PDHV models 6
Beside the standard spout, several pendulum items are available for different applications, such as
for the salt spreading where the spreading width is min. 2 m until max. 4 m, or for using in vineyards,
orchards or in parks.
Spreading spout Width adjustment key
The hopper in fiberglass reinforced plastic cannot rust nor be damaged.
The painting of the frame, as for all Cosmo products, is made by a water base varnish with
successive backing at 150° with the application of the primer bath, assuring a great protection and
long life of the machine.
The feeding of the disc is by gravity through the exits, located on the bottom of the hopper, that can
be opened or closed by a mechanical or hydraulic system (optional). The dosage of the fertilizer is
made by operating on the opening section by a dosing rod that slides on a threaded pin with a
graduate scale.
Standard agitator Crown agitator Opening lever
For the more powdered fertilizers it is possible to settle an agitator/mixer on the bottom of the
hopper to avoid the formation of lumps in the fertilizer.
For the PDV 500 and 600 models the 3-point hitch is only of category I, whereas for the other models
(PDHV 800, 1000, 1250) the hitch is of category I and II.

4. CONNECTIONS
The machine can be delivered all assembled or not (in this case follow the assembling instructions
enclosed). In both cases, before using the spreader it is necessary to control that all the fixing
elements (screws, nuts, washers) are well locked and make sure that all the safety devices are
located at their right position.
Verify that the gear box is fixed to the machine frame by 4 screws: two longer (Hexagonal head
12x50) in the front part, at the Pto shaft connection side, and two shorter (hexagonal head 12x40)
back , at the pendulum side.
Before coupling the machine to the 3-point hitch, positioning the safety devices to the tractor, so that
it is not possible the involuntary and/or accidental raising and lowering of the arms.
The 3-point hitch of the tractor and of the machine must coincide or must be adapted.
In proximity of arms rods of the back lifter of the tractor, there is the danger of wounding, because of
crushing and cutting points.
Do not use the external controls for the lifting of the machine. During transport position block the
lateral stop of the rods.
4.1. CHECK THE RAISING ABILITY OF THE TRACTOR
DANGER!
It is obligatory to check the raising ability and the stability of the tractor
(before carrying out the connection with the machine) in order to avoid
the overturning and/or the loss of wheels grip

4.2. CONNECTION TO THE 3-POINT HITCH OF THE TRACTOR
ATTENTION!
Every time that somebody comes down from the tractor, it is necessary
to disconnect the pto shaft, stopping the engine and to put on the parking
brake.
For the connection of the machine to the tractor, please operate in the following way:
•Step backwards with the tractor until arriving in proximity
of the lower connections of the fertilizer spreader.
•Fix the lower connections of the tractor to the pins of the
machine and lock them with the safety plugs.
•Connect the upper linkage of the machine to the 3-point
hitch of the tractor putting the appropriate pin and block
the anti-unscrewing device of the 3-point hitch;
•Raise the machine of some centimetres by the ground
and operate on the lateral ties of the lifter bars and on
the two turnbuckles, in order to block the lateral movement, so as to prevent excessive
oscillations during the working phase.
The machine must be positioned, through the raising of the lower connections of the tractor, so
that the land distance from the lower extremity of the distributor disc is approximately of 70 cm.
To obtain a regular distribution, it is important that the distributor disc is in horizontal position
compared to the land).
•After having made these operations, the pto shaft must be linked to the smooth shaft of the
gearbox of the machine (covered by a safety cowling) and after to the tractor power take-off.
ATTENTION!
The pto shaft must always be connected at last to the tractor power take off
and disconnected at first, when you stop working.
.
ÂOn demand, the COSMO pendular spreaders can be equipped with a quick attachment (A).
ÂIn order to simplify the connection operation we suggest to assemble the bar (A) on the lower
arms of the tractor’s lifter. Afterwards, in order
to connect the machine, open the connection
hooks (B) by unloosing the fixing nuts (C), bring
the tractor nearer till to put the bar connected to
the lifter in the connection hooks’ slots, lock
them tight and fix them by the bolts.
ÂThe bar (A) must be kept rised (as shown in the
picture) in order to avoid the Pto shaft could hit
with it during the working.

Pendular Spreader PDV-PDHV models 15
4.3. DRIVELINE INSTALLATION
Before using the pto shaft, please consult the use and maintenance manual attached to the
pto shaft.
In case that the pto shaft, supplied with the machine, is not used, please check that the cowlings of
the machines and of tractors are overlapped to the pto shaft’s shield of 5 cm., at least.
For a correct and safe operation of the machine, please use exclusively pto shafts with CE mark.
Please use pto shafts with integral shields
•Grease periodically, the pto shaft following the instruction supplied by the pto shaft manufacturer
(see the use and maintenance manual of the pto shaft).
•Observe the sense of assembly of the pto shaft, as indicated by the manufacturer and shown on
the outer cover of the shield (tractor drawing on the external tube of the pto shaft towards the
power take-off of the same tractor).
•Fasten the safety ant-rotation chains after making sure that the connection between the pto shaft
and the gear box is well locked. Use for this connection an hexagonal head screw 8.8 10x70 UNI
5737 with the relative nut.
ATTENZIONE!
Check the rotation sense and the speed regulation of the power take-off of
the tractor to be at 540 rpm, as the machine is projected for this kind of
speed.
The length of the pto shaft must be adapted to the type of used tractor..
When the pto shaft is released from the power take-off of the tractor must ALWAYS be laid on the
appropriate support.
COSMO Company is not responsible for the damages caused by an incorrect assembly and use of the
pto shaft.
4.4. HYDRAULIC SYSTEM INSTALLATION (OPTIONAL)
In order to recognize the element used, please refer to the tables 08 and 09 of the chapter 8 (Parts
breakdown).
1. Assemble the connection plate for hydraulic opening system (ref. 8) on the gear box by using the
screw and the nut (C) already on the gear box.
2. Fixing the hydraulic cylinder (ref. 1) to the connection plate (ref. 8) by using the screw (ref. 4)
hexagonal head 8x30 (mod. PDV500/600) or hexagonal head 8x25 (mod.
PDV800/1000/1250), the self-locking nut M8 ( ref. 6), the two washers 8x17 (ref. 7) and the
bushing 13x8x7 (ref. 9).
3. The hydraulic cylinder stem must be connected to the lever plate in the hole B. Insert the screw
hexagonal head 12x60 (ref. 3) in the hole B, screw up the nut M12 (ref. 10) insert the screw in
one of the two cylinder holes and fix it by the self-locking nut M12 (ref. 5)

Pendular Spreader PDV-PDHV models 16
5. FERTILIZER SPREADER USE
ATTENTION!
Before use, please check that gears are adequately greased (see paragraph
6.1).
ATTENTION!
During the use of the machine, please be sure that for a radius of 30 meters
there are not any person or animals. If somebody comes up, please stop
immediately the tractor engine.
Recommendations for a correct distribution
•Please test always the kg/ha that you wish to spread before starting to work.
•Do not insert the pto shaft when the tractor is in acceleration, because it will start the
pendulum spreading. Lower the engine revolutions at the minimum and after that speed up
gradually till obtaining a speed of 540 r.p.m.
•Open exits only when the right speed is achieved.
•Avoid to spread the fertilizer in windy days, in order to improve the uniformity of the
distribution.
5.1. ADJUSTMENTS
It is not possible to have an exact spreading chart for equipments that make use of the centrifugal
principle, given that the distributed quantity depends on the feed speed, on the radius of distribution,
on the quality and humidity of the fertilizer and on the roughness of the land.
The fertilizer must always be stored and conserved adequately, so as to keep its physical
characteristics unchanged.
It is necessary to set the speed of the pendular spreader, before starting the operation of distribution,
trying, in the possible limits, to keep it constant for all its duration.
The spreading charts contain the indicative information, in order to determine the quantity to spread
in the field; these must be completed by the experience and competence of the operator.

Pendular Spreader PDV-PDHV models 17
5.1.1. SPREADING WIDTH ADJUSTMENT
With the available adjustable key you can easily adjust the gear box on 3 different spreading widths:
LARGE, MEDIUM, LOW.
These measures can be achieved only by using the standard pendulum and any changes will depend
on the kind of product to spread. (see on spreading charts paragraph 5.1.4).
Insert the key in the gear box device, as shown in the
picture, and push it slightly till the end of the tracks. You
can insert the key in any way because the mechanism
allows to put the key on a slot different from the
spreading setting.
The adjustment key turns in a clockwise and anti-
clockwise direction indifferently. When the arrow is in
LARGE position, you can achieve a spreading width from
10 to 12 meters;
to get 8 – 10 meters turn the key towards “LOW”
setting.
Once you have chosen the spreading width pattern, pull out the key form the adjustment device.
To get lower or specific spreading widths, use the proper spout (when available) or reduce the
revolutions of the PTO.

Pendular Spreader PDV-PDHV models 18
5.1.2. SPREADING QUANTITY ADJUSTMENT
The fertilizer spreading is regulated by a metering rod that operates on the opening width of the exits
on the bottom of the hopper.
In order to adjust the fertilizer quantity to spread, follow the slide ruler carefully (attached to this
manual) and the spreading chart (stuck on the hopper and located in the manual itself, see on
paragraph 5.1.3).
The recorded data will be kept only if:
1) a standard pendulum is used;
2) the distance between the ground and the pendulum end is about 75 cm ( working height)
3) the rotation speed of the power take-off is 540 r.p.m.
In order to achieve a right adjustment follow the instructions below:
1) Establish the spreading width you want to adopt (see on paragraph 5.1.1.).
EXAMPLE 1: Spreading width chosen = 12 meters
2) Establish the quantity of the product you want to spread for a surface unit (kg/ha or lbs/acre), by
moving the inner part of the slide ruler.
EXAMPLE 2: quantity spread for hectare 200 kg

Pendular Spreader PDV-PDHV models 19
3) Establish the feed motion speed to be kept during the working (from 4km/h to 15 km/h).
EXAMPLE 3: feed motion speed = 6 km/h
4) Control on the slide ruler the product quantity in kg/min (or lbs/ min) that will be spread.
EXAMPLE 4: Product quantity to be spread = 24 kg/min
5) see the Spreading Chart label affixed on the hopper and shown on next paragraph (5.1.3).
According to the type of fertiliser (or product) used and to the product quantity in kg/min
