FLAIL MOWER - FMH Series
5.3. ADJUSTMENTS
WARNING
All adjustment operations must be performed with the tractor engine off, the PTO disengaged, the flail
mower lowered to the ground or on security stands, the parking brake set and the ignition key off.
CUTTING HEIGHT ADJUSTMENT
The cutting height of the flail mower is determined by the vertical position of the rear roller (or the
pivoting wheels) on the machine.
Lifting up the roller (or the wheels) the tools of the rotor get closer to the ground, reducing the cutting
height. On the contrary, lowering the roller (or the wheels) the tools increase their distance from the
ground, increasing the cutting height.
After a change of the working height, make sure that the tools of the rotor are not interfering with the soil:
a direct contact with the ground would facilitate the rapid wearing of the tools.
If the flail mower is provided with a stabilizer roller, to adjust the cutting height:
• lift the flail mower, put it on safety stands, then turn off the tractor engine, disengage the PTO, set the
parking brake and remove the key from the panel;
• remove the bolts (1) that secure the roller supports to the frame on both sides;
•
position the roller according to the height required;
• Replace and tighten the bolts (for the correct torque value refer to the torque table of the manual).

Depending on the different roller positions, it is possible to set four different cutting heights: 32-57-82 and
107 mm.
When finished, make sure that the roller supports are positioned at the same height, and check, with
the flail mower resting on the ground, that the front of the machine is leveled with the back. If
necessary, adjust the level through the 3-point top link of the tractor.
