11 – 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.
Note: in the walking tractors with ground clearance of the PTO less than 25-26 cm, it is advisable to
use shorter hoes (ask the dealer or the R2 technicians).
When replacing the hoes, the implement must be disconnected from the two-wheel
tractor.
Lay the machine on a flat, smooth and stable surface with a suitable capacity.
11.1 Positioning the implement
1) Disassemble the implement from the walking tractor;
2) Disassemble the roller group and the roller adjuster (Fig. 14);
3) Disassemble the lateral protections (Fig. 14); afterwards put again the screws M10x110 with the
spring (this will be useful to keep the sides integral with the machine); Lay down the machine so
that it rests on the rear of the sides (Fig. 15).
WARNING: The hoe area is dangerous (Fig. 16). 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.
11.2 Replacement of the hoes
Using an automatic screwer and a monkey spanner for bolts of 10 mm (3/8”), 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. 17 – Ref. C). Whenever replacing
the hoes, always use new screws and bolts.
After replacing the hoes, reassemble the lateral protections, the roller group and the roller register
handle.
While replacing the hoes, wear safety shoes and
glasses and protective gloves. While using the
pneumatic screwdriver wear ear protections and
safety glasses.
