WARNING
Never use the machine to transport or lift people, animals, or objects.
WARNING
Make certain, by adding front ballast, that at least 20% of the total weight (tractor, implement and ballast)
is on the front axle of the tractor, to ensure stability.
WARNING
Before engaging the tractor PTO, make sure the tractor PTO speed is set as required for the mulcher (540 rpm).
Do not over speed PTO or machine breakage may result.
DANGER
Do not operate the mulcher if the driveshaft is damaged. The driveshaft could be subject to breakage during
operation, causing serious injury or death. Remove the driveshaft and replace it with an undamaged.
WARNING
With mulcher disconnected from tractor, rest the driveline on the provided support of the mulcher.
3.3. OPERATING SAFETY INSTRUCTION

SFM
Series V2
DANGER
In presence of steep slopes (greater than 15 degrees) the rotating action of the implement may cause instability of
the tractor with risk of serious injury or death hazard. Consult the tractor manual to determine the maximum slope
that the tractor is designed to operate.
DANGER
Always disengage the PTO before raising the mulcher, and never engage the PTO with the mulcher in the raised
position. The machine might throw objects at high speed, causing serious injury or death.
WARNING
Never leave the driver’s seat when the tractor is turned on. Before leaving the tractor, lower the mulcher to
the ground, disengage the PTO, insert the parking brake, stop engine and remove the key from the control panel.
DANGER
The PTO shields of tractor and implement side, the driveshaft shielding and the driveshaft retaining chains must be
properly installed and in good condition, to avoid risk of entanglement with serious injury or death.
DANGER
Before engaging the PTO of the tractor, always make sure that the driveshaft is mounted in the correct direction,
and that its clamping elements are properly connected both to tractor side and to mulcher side.
WARNING
Stop operating immediately if blades strike a foreign object. Repair all damage and make certain rotor and blades are
in good condition before resuming operation.
WARNING
Always disengage the tractor PTO when the driveshaft exceeds an angle of 10 degrees up or down while
operating. An excessive angle with driveshaft rotating can break the driveshaft and cause flying projectiles.

Prolonged use of the mulcher can cause overheating of the gearbox. Do not touch the gearbox during use and
immediately after, it could be extremely hot and cause severe burn.
WARNING
All adjustment operations on the mulcher must be performed by qualified and trained operators, with the tractor
engine off, the PTO disengaged, the mulcher lowered to the ground or on security stands, the ignition key off and the
parking brake set.
3.4. TRANSPORTING SAFETY INSTRUCTION

exposed.
WARNING
When turning, use extreme care and reduce tractor speed.
WARNING
Do not operate the tractor with weak or faulty brakes or worn tires.
CAUTION

4. SET UP
The mulcher is delivered equipped with a PTO driveshaft and related operating manual.
When the machine is delivered, check that there is no damage to the mulcher or PTO driveshaft. In case of damage or
missing parts immediately notify the Importer or your Dealer.
Because of its size, the mulcher might be delivered partially assembled. In this case, the assembly of such parts is the
responsibility of the owner and must be performed carefully, with reference to the information in the spare parts
section.
WARNING
For proper tightening torques of bolts and screws, refer to the table in this manual (page 38)
4.1. CONNECTING TO THE TRACTOR
The mulcher is designed to be mounted on tractors equipped with 3-point Hitch Category I (ISO
730 standard).
WARNING
Before connecting the mulcher to the tractor, make sure you are on a flat, stable, dry surface.
To connect the mulcher to the tractor the operator must do the following:
 Remove the safety clips and mounting pins from the mulcher;
 Reverse the tractor up to the mulcher making sure to align the tractor’s lower linkage arms in between the lower
hitch points of the mulcher (see picture below);
 set the tractor’s parking brake, stop engine, remove the ignition key and get off the tractor;
NOTE: the lower linkage arms of all tractors can be adjusted both vertically and laterally.
The lateral movement allows you to position the arm between the hitch point and provides a little movement to
assist you to fit the pin that connect the mulcher to the tractor.
The vertical adjustment ensures you can ensure the mulcher is level (left to right across the width of the tractor).
Loosen the arms to make connecting easier BUT always ensure you tighten them to prevent movement/swinging
that could compromise the stability of tractor and machine.
 slide the pin into the mulcher lower hitch point, through the tractor’s lower linkage arm and out the other side of
the mulchers lower hitch point. Secure the pin with the safety clip then repeat for the other side/arm.
 adjust the tractor’ top link so you can secure it to the upper top hitch point of the mulcher with the pin and slip.
 the mulcher must be parallel to the ground when operating. Once you have determined the cut height (by setting
the skids and/or rear roller) wind the tractor’s adjustable top link in/out to adjust the position of the mulcher.
 when raised on the tractor’s lower linkage arms, the mulcher should also be leveled left to right. If one side is
higher/lower than the other, adjust using the vertical adjustment found on one of the tractor’s lower linkage arm.
 finally raise the parking stand to the highest point and secure with the safety pin/clip.
