Introduction
The ATCR, ATCRL, GAICR and GAICR 300 disk harrows
were designed to work in any type of soil and they provide an
excellent seedbed preparation for annual and perennial crops.
The rugged structure has an adequate size and is made of
folded steel plates, joined by a good weld penetration and fine
finishing, with resistant parts on the force concentration.
These disk harrows have an efficient wheel system
composed by tires and hydraulic cylinders, which allow the
transportation over long distances.
This operator's manual contains the necessary information
for the best performance of these equipments. The operator
must carefully read the entire manual before working
with the equipment. Also, read and understand the safety
recommendations.
For any further explanation or in the case 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.

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.

Working safety standards
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.
