15 – Replacing the hoes
Working the soil determines a gradual consumption of the hoes.
When the hoes have become a length of 8 cm, they must be replaced. Using the implement with
tools of a length less than 8 cm may cause a reduction of the tillage quality and increase the risk of
clamping and damages to the milling group.
When replacing the hoes, the implement must be disconnected from the loader.
Never let yourself or any part of your body get underneath the implement while it is
raised by the loader.
Lay the implement flat, on a smooth and stable surface with a suitable capacity.
15.1 Positioning the implement
1) Disassemble the implement from the loader (see procedure in point 1 of paragrapf 5 on pag. 12)
and detach the implement from the loader by following the inverse sense of the assembly
procedure found under paragraph 7 on page 16.
2) Disassemble the roller group (or the optional seeder unit) and the roller adjuster.
3) Disassemble the side protections (Fig. 28 – Ref. A).
4) Lay down the implement and lean it on the rear part of its sides (fig. 29).
WARNING: The hoe area is dangerous (Fig. 29). During these operations, position
yourself firmly and securely and make sure that your face and your body will not be
pressed against the hoes.
Do not allow people or animals to approach the area of the knives. If it should be necessary to leave
the implement unattended in this position, protect the hoe area with a rigid panel in order to avoid
dangerous accidental contact with the hoes by third parties.
15.2 Replacement of the hoes
Using a 17 mm (11/16”) pneumatic screwdriver and a wrench, unscrew the fastening bolts of the old
hoes and screw in the new hoes, ensure that the hexagonal head of the screw is inserted into the
hexagonal seat of the hoe support bracket (Fig. 30). Whenever replacing the hoes, always use new
screws, bolts and split washers.
After the replacement of the hoes, reassemble the roller unit or the seeder unit (note: the tightness of
the fastening screws of the roller assembly and the roller adjuster should allow the components to
turn round/slide respectively one against another) and the side protections.
While replacing the hoes, wear protective gloves,
safety shoes, ear protection and safety glasses.
While using the pneumatic screwdriver wear ear
protections.
When working with the implement in a raised position wear safety shoes.
