Introduction
The DCA DC spreader performs an oriented distribution of fertilizer with higher income,
saving more product and it is extremely easy to operate.
DCA DC 2500, DCA DC 5500 and DCA DC 7500 models have cardan shaft and belt
transmissions to activate the conveyor and the rotating discs.
The tandem rocker arm wheelset type (DCA DC 5500 & 7500 models) have four tires
that follow the soil profile precisely.
The stainless steel conveyor has tighteners for tension adjustment.
The opening of the dosing gate has a graduated scale with easy adjustment, allowing
several rates of distribution.
The fins have adjustments over the rotating discs to properly distribute different
products.
The DCA DC spreader is recommended to optimize the fertilization on orchards and
coffee plantations, providing increased productivity and assuring the distribution of the
proper amount of product on the correct spot.
This spreader applies fertilizer on orchards with new or grown plants, always preserving
the leaves integrity. The appplication on continuous strips or in a intermittent way avoids
the waste of fertilizer if the field is about to end or have any failure by turning off one of
the conveyors.
This equipment also allows the application of small or great amounts, but always
respecting the agronomic recommendation.
The product directioning is done through the tubes with adjustments of the horizontal
and vertical angles.
The DCA DC also presents the intermittent fertilizing system, which distributes the
fertilizer on each plant. This system is recommended for new orchards.
This instructions manual contains the necessary information for the best performance
of this spreader. The operator must carefully read the entire manual before working with
the equipment and also read and understand the safety recommendations.
For any further clarification or in the event of technical problems that may arise during
the service, consult your dealer and the Technical Support department of the factory. They
can ensure the fully functioning of your TATU spreader.

To the operator
Dear user!
Respect the ecology. Do not throw trash away. This gesture
of goodwill helps to protect our environment.
Products such as oil, fuel, filters, batteries and others are
spilled to the soil and can penetrate to the underground layers,
compromising nature. Ecological and conscious disposal of them
should be done.
Working safely
Be careful with the environment
The spreaders are simple to operate, requiring however the
basic and essential cautions to their handling.
Always keep in mind that safety requires constant attention,
observation and prudence during spreading, transportation,
maintenance and storage.
Read and understand the information before making any
adjustment or maintenance.
Have extreme caution when operating with the power take-off
(PTO). Do not get closer during operation.
Never use your bare hands to check hydraulic leaks, the high
pressure can cause several injuries.
• Security aspects must be carefully observed to avoid
accidents.
• This symbol is a warning used to prevent accidents.
• The instructions under this symbol refers to the safety of the
operator or third parties, therefore they should be carefully
read and observed.

Transportation over truck or trailer
Marchesan does not advise the equipment traffic on highways, because this
practice involves serious security risks in addition to being prohibited by the
current existing traffic law. The transportation for long distances should be done
on truck, trailer or others by following these safety guidelines:
• Use adequate ramps to load or unload the equipment. Do not make the loading
on ditch banks, it can cause a serious accident.
• When lifting with a hoist, use the appropriate points to lift.
• Use parking stands to support the equipment appropriately.
• Fasten the moving parts that may get loose and cause accidents.
• Underpin the equipment wheels appropriately.
• Use chock blocks and safety chains to secure the equipment to the truck or trailer
during the transport.
• After 8 to 10 km transporting, please inspect the load condition. Repeat this
procedure every 80 to 100 km. Give more attention when transporting the
equipment on rough roads, slopes and other adverse conditions.
• Always be careful with the load height, especially when passing under electrical
power lines, bridges and others.
• Check all laws and regulations regarding the height limits and load width while
transporting the equipment on truck or trailer. If necessary use banners, lights
and other devices in order to give adequate warning to the other drivers.

Set-up instructions
Hitching to the tractor
Hitch the drawbar to the tractor hitch bar, placing a pin (A) and cotter pin. To facilitate
hitching, use the parking jack (B) adjustment.
• The hitch part that has a round hole must be facing upwards.
• After hitching, leave the parking jack (B) in transport/operation position,
as shown below.
• Keep the tractor hitch bar centered.

Set-up instructions
DCA DC leveling
After hitching the drawbar, check the horizontal leveling of the spreader. If required,
make any adjustment as follows:
Consult the tractor manual and be sure about the possible working positions with the
hitch bar. Use the height that provides the best leveling of the equipment.
First of all, verify the length of the cardan shaft in the following way:
• Separate the cardan shaft and couple the 'female' part to the PTO.
• Steer the tractor wheel until it touches the spreader drawbar.
• Couple the 'male' part to the spreader. Being the bars placed side by side, verify the
existence of a minimum free space of five centimeters between the male and female part
in each end.
Coupling the cardan shaft to the PTO
NOTE The adjustment range of the tractor drawbar can be used for shortening it
or lengthening it.

Set-up instructions
Reducing the cardan shaft length
If it is necessary, cut similar parts of the male and female shaft as well as the protection
covers. But before cutting the shaft, verify all possibilities of usage without reducing its
length.
The length adjustment will be done when the distance between the equipment and
tractor do not allow coupling. Proceed as follows:
• First of all, disassemble the protection
covers.
• Cut the hub and the solid bar (male and female)
in the desired measures. In order to do so, couple half
of the cardan in the tractor and half in the equipment,
placing the semi-cardans in parallel and in several
operating positions. Then, determine the correct length
and mark the cutting area.
• It is important to give finish working in the cut
parts. For this purpose, use a filer. Soon after, remove
the filing and lubricate the 'male' with a fine layer of
grease.
• Decrease the length of both protective covers,
using the cut tubes as a measure and clean the cut
residues.
• Then, assemble the cardan shaft, according to
the instructions on the next page.
• When using another tractor to work with
the spreader, verify the length of the cardan shaft
again.
• The chains of the protection covers should be
fastened in the equipment and in the tractor, so that
they will not get loose during maneuvers.
