Introduction
GAPCR and GASPCR disk harrows are designed to work in any
kind of soil with excellent application, mainly in newly cleared areas,
in the heavy sugar cane renewal, pasture recovery, construction of
highways or in the simple primary soil tillage for annual and perennial
crops, disaggregating and incorporating stubbles to greater depths.
The heavy-duty structure with proper dimensioning is made of bent
steel plates joined by a good penetration and fine finishing welding
process, with tough parts in the mechanical load concentrations.
The transportation of these disk harrows are made through an
efficient wheelset system composed by tires and hydraulic cylinder,
which allows long-distance transportation. The wheelset system also
streamlines the operation through the fast and precise working depth
control, as well as facilitate maneuvers during the service.
This operator's manual contains the necessary information for the
best performance of these disk harrows. The operator must carefully
read the entire manual before working with the equipment. 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 disk harrow.

To the operator
Never use your bare hands to check hydraulic leaks, the high
pressure can cause injuries.
Never attempt to change the adjustments, clean or lubricate the
equipment when the same is switched on or in movement.
Be careful while driving on slopes. Risk of overturn.
Prevent that chemical products (i.e.: fertilizers, treated seeds)
make any contact with your skin or clothes.
Keep access and work places clean or free from oil and grease.
Risk of accidents.
Never transport the equipment on highways or paved roads
during the night. Avoid that the tractor wheels touch the drawbar in
sharp turns.
The presence of any other people on the tractor or equipment
is stricly forbidden.
Have extreme caution when driving under electrical power lines.
Any contact may result in severe shocks, injuries or death.
For your protection and safety, always wear adequate clothes

To the operator
• Only trained and qualified personnel are allowed to operate the equipment.
• While working or during transportation, only the presence of the operator is
allowed on the tractor.
• Do not allow children to play or to get over the equipment, while it is operating,
during transportation or storage.
• When setting the disk harrow to transport position, check if there are no people
or animals close or under it.
• Use personal protective equipment (PPE).
• Wear appropriate clothes and footwear. Avoid clothes that are either loose or
hanging from the body, which may become entangled in moving parts.
• Wear protective gloves to work near the cutting parts.
• Never operate the equipment without its protective devices.
• Have full knowledge of the soil before starting to work. Use the speed which is
suitable to the conditions of the ground or pathways to be covered. Provide the
delineation of obstacles or hazardous locations.
• Carefully check the transport width on narrow locations.
• Be careful while hitching the equipment to the tractor.
• Only pull the equipment using a tractor with appropriate power.
• Do not drive the equipment under the influence of alcohol or any soothing/
stimulating medicine, as it may result in a serious accident.
• In case of a fire outbreak or any possible hazard, the operator must leave the
area as fast as possible and look for a safe place. Always have emergency
numbers at hands.
• In case of emergency, know how to stop the tractor and disk harrow quickly.
• Always shut down the engine, remove the key and use the handbrake before
leaving the tractor seat.
• Never attempt to change the adjustments, clean or lubricate the equipment while
it is moving.
• Whenever you unhitch the equipment, either in the field or shed, do it on a flat
and firm surface and use parking jacks. Make sure the equipment is properly
supported.
• We suggest that you carefully read the manual, as it will be a guide for periodic
verifications that need to be done and will allow that you assure the maintenance

Transportation over truck or trailer
To the operator
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.
• Underpin the equipment appropriately.
• Use chock blocks and safety chains to secure the equipment to the truck or
trailer during the transport.
• Make sure the SMV (Slow Moving Vehicle) sign, and all the lights and reflectors
that are required by the local highway and transport autorithies are in place, are
clean and can be seen clearly by all overtaking and oncoming traffic.
• 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.

To the operator
It is important to have knowledge not only about the functioning, operation of the
equipment and its technology, but also the working legal aspects when using the equipment,
such as: safety standards, operator's manual and working safety.
The equipment and tools used on the rural area must be properly handled, otherwise
health and safety of involved personnel may be compromised.
The operator must be capable and authorized to operate the tractor, meaning that
that person must comprehend the functioning instructions of the tractor and know about
the safety standards regarding the job that will be performed.
The Ministry of Labor and Employment created safety standards that aim to decrease
the risk of accidents that may occur to the rural worker. Related to the subject of agicultural
machines and equipments, we specifically cited the NR 06, NR 12 and NR 31 standards.
Regulatory Standard - NR 06:
• For purposes of applying this Regulatory Standard, Personal Protective Equipment
(PPE) is considered any device or product that is worn by an individual worker for protection
against risks that could threaten safety and health at work.
Regulatory Standard - NR 12:
• This Regulatory Standard and its annexes provide technical references, basic
principles and protective measures to ensure the health and physical integrity of workers
and establishes minimum requirements for the prevention of accidents and occupational
diseases in the design stages and use of machinery and equipment of all kinds, and also to
its manufacture, importation, trading, exhibition and cession in any way. It is understood as
using phase the construction, transportation, assembly, installation, adjustment, operation,
cleaning, maintenance, inspection, disabling and dismantling of machinery or equipment.
Regulatory Standard - NR 31:
• This Regulatory Standard has the purpose to establish the precept to be applied on
the organization and on the working environment, in order to make compatible the planning
and development of agriculture, livestock, forestry, forest exploration and aquaculture with
safety on the working environment.
