3. INTENDED USE OF THE FLAIL MOWER
The NANO front flail mower is intended for mowing squares, pitches, parks, small thicknes,
weeds, etc. of moderate density.
The mower comes with drive and hitch in many various versions which allows for adaptation
of the mower to operation with many vehicle types fitted with front PTO shaft or own hydraulic
assembly (small municipal tractors, garden tractors, mini back hoe loaders).
WARNING!
It is forbidden to use the flail mower for purposes other than those listed in
this instruction. Using the flail mower for other purposes will be classified as
use not according with the intended use and could exclude the manufacturer
from responsibility from any resulting damages. The flail mower should be
used, serviced and repaired only by persons familiar with its characteristics
and with safety regulations. Unauthorized modification of the flail mower may
release the manufacturer from responsibility for any resulting malfunctions or
damages.

3.2. Construction and operation
The construction of NANO 150 H flail mower shown in Fig. 2.
Hydraulic drive front the vehicle is transmitted to hydraulic motor (1) of the mower and then
on the belt gear (2) powering the flail shaft (3) on which flail knives (4) are mounted.
Clevis feet of the flail blades (cutting) functions as a safeguard of the operating elements from
overloading and damage. During operation if the value of resistance force of the obstacle exceeds
the value of the centrifugal force of the blade, the blades tilts back and avoids the obstacle.
The mowing height is regulated by adjusting the position of the copying shaft (5) and support
wheels (9).
Steel skids (8) protect the machine when passing through an obstacle.

The construction of NANO 150 flail mower shown in Fig. 3.
Drive from the vehicle PTO shaft is transmitted through jointed telescopic shaft and
intersection angle gear (1), mounted on the mower load bearing body, onto driving shaft (2), and
then the belt gear (3) is driven by the flail shaft (4) on which flail knives (5) are mounted.
Clevis feet of the flail blades (cutting) functions as a safeguard of the operating elements from
overloading and damage. During operation if the value of resistance force of the obstacle exceeds
the value of the centrifugal force of the blade, the blades tilts back and avoids the obstacle.
The mowing height is regulated by adjusting the position of the copying shaft (6) and support
wheels (10).
Steel skids (9) protect the machine when passing through an obstacle.
