THE SAFETY ALERT SYMBOL IDENTIFES IMPORTANT MESSAGE ON THE MESSAGE ON THE ENGINE, WHEN YOU SEE THIS SYMBOL, BE ALERT TO THE
POSSIBILITY OF DEATH OR PERSONAL INJURY. FALLOW THE INSTRUCTIONS IN THE SAFETY MESSAGE.
WARNING WARNING WARNING
• Do not work with the tractor
if the front bee without enough
weight to the rear equipment.
There is tendency to lift , add
weights at front or front wheels.
• Before any equipment main-
tenance, make sure that is pro-
perly stopped
• Avoid getting hit
• Never weld the wheel mounted with tire,
the heat may cause air pressure increase
and provoke the explosion of the tire.
• When lling the tire, stand at the side of
the tire, never in froint of it.
• When lling the tire, always use a contain-
ment device (lling cage).
WARNING
• Do not perform adjustments
while GTCR/GTCR-CR is running.
• When performing any servi-
ce on GTCR/GTCR-CR, switch o
the tractor rst. Use appropria-
te tools.

ALCOHOLIC BEVERAGE OR SOME MEDICATIONS MAY CAUSE LOSS OF REFLEXES AND CHANGE THE OPERATOR´S PHYSICAL CONDITIONS. FOR
THIS REASON, NEVER OPERATE THIS EQUIPMENT UNDER ANY OF THESE SUBSTANCES.
01  SAFETY RULES
WARNING WARNING
• The hydraulic oil operates pressurized and can cause serious injuries, in case of
leakage. Periodically verify the condition of the hoses. If there are any signs of
leakage, replace them immediately.
• Before connecting or disconnecting hydraulic hoses, release the pressure from
the system, activating the control when the tractor is turned o.
• Dispose residues inappropriately
aects the environment and the ecolo-
gy since you will be polluting rivers, ca-
nals or the soil.
• Inform yourself about the proper way
of recycling or disposing residues.
PROTECT THE ENVIRONMENT!
WARNING
• Keep away from the active seeder ele-
ments (discs), they are sharp and can
cause accidents.
• Whenever performing any work on the
discs, wear safety gloves on your hands.

Instruction Manual

The incorrect handling of this equipment can result in serious or fatal accidents. Before using the implement, read carefully the instruc-
tions of this manual. Be sure that the person responsible for the operation is instructed about the correct handling, safety and if read and
understood the instructions manual concerning this machine.
WARNING
01 - When operate with the implement, do not allow people to stay close or above the implement. (The platforms are used to supply the stores
and not to transport people).
02 - During assembly or desassembly the discs section use proctection gloves.
03 - When turn on or o the hydraulic rubbers, alleviate the circuit pressure.
04 - Check periodically the rubbers conservation. If there is indicium of oil emptying change it immediatelly because the oil works under high
pressure and may cause serious damages.
05 - Do not use much large clothes because they can fasten the implement.
06 - Putting in action the tractor, be correctly placed at the operator seat and aware about the correct and safety handling both tractor and
implement. Place always the gearshift crank at the neutral position, turn o the gear of the power command and place the hydraulic commands at
the neutral position.
07 - Do not turn on the tractor in a closed place, without appropriate ventilation because the gas are bad for health.

Instruction Manual
GTCR/GTCR-CR  8 9  GTCR/GTCR-CR
08 - While maneuver the tractor to clamp the implement be sure if there is space enough and nobody is too much close, maneuver always in slow
gear and be ready to brake in case of emergency.
09 - Do not adjust the implement working.
10 - Working in inclined soil try to keep the necessary stability. In case of instability reduce the acceleration, turn the wheels to the inclined side
of the soil and never lift the implement.
11 - Conduct the tractor always in safety speeds, specially working in irregular or inclined soil, keep the tractor always geared.
12 - In case of conducting the tractor on road, keep the brake pedal connected.
13 - Do not work with the front of the tractor light. If there is trend to lift up add more weight in front or at the front wheels.
14 - Getting out the tractor place the gearshift at the neutral position and apply the park brake. Do never let clamped implements at the tractor
with the hydraulic system at the lifted position.
15 - Drugs and alcohol will aect an operator’s alertness and coordination. Do not operate any engine under these conditions.
16 - Explain the operation, inspect and maintenance instructions to those users or operators who can not read.

04  MOUNTING
1 - Before you start... Check if you receive the product without any violation
of the packing. In case the cargo has signs of violation, call the insurance
agent to witness the fact and assist further unpacking of the cargo for mis-
sing items.
2 - Prepare the unloading area for a clean, safe and organized operation and
do not allow the people to work without safety material such as gloves.
3 - Assembling normally starts with the disc gangs .The gang components
leave the factory pre-mounted without the disc blades.
Carefully dismount the gang , leaving the parts precisely in the same se-
quence order, withouit turning the separatar spools and bearing housings
around, because the extremeties of those have a concave face on one and
a convex face on the other and this is not so easy to see, if you don’t pay at-
tention to it . These faces match with the convex and concave disc surfaces
for a tight t.
4 - Fig (3) shows the mounting sequence of the axle assemblies.
5 - The bearings housings have either a grease nipple or an oil ll plug.
Mounted correctly on lhe harrow, these components should be in the op-
posite of the drive direction.
