2. To the operator
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:
1. Use adequate ramps to load or unload the equipment. Do not make the
loading on ditch banks, it can cause a serious accidents.
2. When lifting with a hoist, use the appropriate points to lift.
3. Use the jacks to support the equipment properly.
4. The drawbar must be lifted and locked on a vertical position or it must be
removed and fastened to the load.
5. Fasten the moving parts that may get loose and cause accidents.
6. Underpin the equipment wheels appropriately.
7. Use chock blocks and safety chains to secure the equipment to the truck or
trailer during the transport.
8. Stay away from the straps, cables or chains that are working under load.
9. 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.
10.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.
11.Always be careful with the load height, especially when passing under
electrical power lines, bridges and others.
12.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 to give adequate warning to the other drivers.

2. To the operator
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, NR 17 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 17:
• The purpose of this Regulatory Standard is to establish parameters for the adaption
of the working conditions to the psycho-physiological characteristics of the workers in order
to provide maximum comfort, safety and efficient performance.
• The working conditions include the aspects of lifting, carrying and unloading materials,
furnitures, equipments and environmental conditions of the job and the organization of work
itself.
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.

3. Data sheet
- To avoid damages, serious accidents or death, do NOT allow passengers on any part
of the equipment.
- The equipment must not be used by an inexperienced operator or one that do not
know every conduction, operation and command controlling techniques.
Intended use of the equipment
Prohibited use of the equipment
The no-till seed drill models SDA³ and SDA³ E are designed to perform the plantation of
several small grains, such as: wheat, rice, soybean, oats, barley and others. They feature a
better uniformity in the seeds and fertilizer distribution, greater versatility during operations
and proper fittings to your needs as the main advantages.
The seeds are distributed by a seed metering system with simultaneous seed discharge
adjustment. The metering is obtained by the graduated scales in the hoppers. On this system,
the seeds are distributed in continuous and uniform rows.
Seeking for the best utilization, the SDA³ and SDA³E models can be optionally supplied
with:
- Special box to distribute fine seeds (pastures);
- Horizontal metering for large seeds with perforated plates, used for corn, soybean,
bean, sorghum and so forth.
The fertilizer is distributed through a helical-type auger and the metering is obtained
by the sprocket combinations, providing uniformity in every row unit.
