Use extreme caution during loading and unloading operations. These tasks must be performed by trained and qualified
personnel using appropriate lifting equipment.
For transport, place the machine securely on pallets and fasten it with suitable restraints. Always use lifting equipment
with sufficient rated capacity.
Do not lift the machine using straps alone. Use only the designated lifting points and approved lifting hooks or cables as
indicated on the machine.
Before attaching the rotary tiller, ensure that the tractor has adequate lifting capacity and stability for the installed
equipment.
Front ballast may be required to maintain proper weight distribution and steering control.
Failure to verify tractor capacity and stability may result in loss of control, tipping, or serious injury.
Verify the lifting capability and the stability of the tractor through the following formula and if necessary apply frontally
the ballasts.

Attaching implements affects tractor handling, steering, and braking performance.
Ensure adequate front axle load after installation. The front axle must support at least 20% of the tractor’s unloaded
weight.
Before installation, secure the tractor’s hydraulic controls to prevent unintended movement.
The rotary tiller must be compatible with a standard three-point hitch system.
Keep hands and body clear of lift arms and linkage areas during installation.
Do not use external hydraulic controls while attaching the machine.
Lock all stabilizers and lift controls before transport.
Park the tractor on level ground, shut off the engine, and engage the parking brake.
Align the lower lift arms with the hitch points and secure them using approved hitch pins and safety clips.
Attach and adjust the top link so the rotary tiller remains level during operation.
Ensure rotor blades do not contact the ground while rotating. If equipped with depth skids, verify full ground contact.
ASSEMBLY AND ADJUSTMENT
Connect the PTO shaft to the gearbox and tractor PTO output. Ensure the safety lock is engaged and the anti-rotation
chain is secured.
Operate only at 540 RPM PTO speed. Always connect the PTO shaft last and disconnect it first.

USE OF THE MACHINE
USE OF THE MACHINE
During operation, the operator must wear suitable person-
al protective equipment, including protective footwear,
work gloves, protective clothing, eye protection, and
hearing protection. Proper PPE helps reduce the risk of
injury caused by debris, noise, or contact with moving
parts.
Ensure that all bystanders remain at a safe distance. A
minimum distance of 165 feet (50 m) is recommended
depending on operating conditions.
PERSONAL PROTECTIVE EQUIPMENT
SAFE OPERATING AREA
Before dismounting from the tractor or carrying out any
maintenance, adjustment, or inspection, engage the
parking brake, disengage the PTO, shut off the engine,
remove the ignition key, and wait until all rotating and
moving components have completely stopped.
BEFORE LEAVING THE TRACTOR
Do not operate the rotary tiller in reverse. When changing
direction or turning, always raise the implement
completely out of the soil. Turning with the tiller engaged
in the ground may result in equipment damage or loss of
control.
OPERATING RESTRICTIONS
Operation in dry soil conditions may generate dust. It is
recommended to use a tractor equipped with an enclosed
cab and air filtration system or to wear appropriate respi-
ratory protection such as a dust mask or filtered respira-
tor.
DUST AND RESPIRATORY PROTECTION
The use of mounted or towed implements can significant-
ly affect tractor handling, steering response, and braking
performance. Extra caution must be taken when turning,
as the altered center of gravity may increase centrifugal
forces.
TRACTOR HANDLING AND STABILITY
All nuts, bolts, and fasteners must be inspected periodi-
cally. Retighten any loose components to ensure safe and
reliable operation.
FASTENER INSPECTION
For transportation and packaging efficiency, the rotary
tiller may be supplied partially disassembled. Detached
components are packed together with the main unit. In
most cases, the three-point hitch frame is shipped sepa-
rately and must be assembled at the customer’s location
before operation.
•Before starting the machine, verify that the rotary tiller
is in proper working condition, that all lubrication points
are correctly serviced, and that no components show
excessive wear or damage.
•Ensure the tiller is correctly positioned to achieve the
desired working depth.
•All safety guards and protective devices, which may
have been removed for shipping, must be properly
installed and secured before commissioning the
machine.

Check the tightness of all fastening nuts.
After 50 Operating Hours
Check the oil level in the transmission unit and restore it
to the correct level as required.
Every 100 Operating Hours
Recheck the transmission oil level and top up if neces-
sary.
Note: Torque values are approximate and provided for
reference only. Always follow fastener manufacturer
specifications.
The rotor shaft is factory balanced. When replacing blades
or tools, it is strongly recommended to replace the entire
set to maintain proper balance.
Installing non-original or mismatched components may
cause excessive vibration and can lead to premature
bearing failure.
Replacement of damaged rotor components must be
performed by qualified service personnel.
ROTOR
Routine maintenance must be performed with the rotary
tiller disconnected from the tractor and positioned
securely on level ground.
All inspection, adjustment, and cleaning work must be
carried out only when:
The implement is resting on the ground
The tractor engine is shut off
The PTO driveline is disengaged
The parking brake is applied
The ignition key has been removed
Adjustments must only be made with the engine shut off,
PTO disengaged, ignition key removed, and all mechanical
components completely stopped.
In the event of a malfunction, the operator must immedi-
ately disengage the PTO, turn off the engine, remove the
ignition key, exit the tractor, and identify the cause before
