5 ASSEMBLY AND SET-UP
Before coupling the machine to the 3-point hitch, positioning the safety devices to the tractor, so that it is not
possible the involuntary and/or accidental raising and lowering of the arms.
The 3-point hitch of the tractor and of the machine must coincide or must be adapted.
In proximity of arms rods of the back lifter of the tractor, there is the danger of wounding, because of
crushing and cutting points.
Do not use the external controls for the lifting of the machine. During transport position block the lateral stop
of the rods.

TRACTOR REQUIREMENTS AND 3-POINT HOOK-UP
DANGER!
It is obligatory to check the raising ability and the stability of the tractor
(before carrying out the connection with the machine) in order to avoid
the overturning and/or the loss of wheels grip.
Before connecting the machine to the tractor is required to check the stability of the tractor machine system,
in order to determine the ballast to apply to the front of the tractor, to ensure adequate distribution of the
weight on the axles.
In order to assure the stability it is necessary that the following relations are verified (see table below for
definitions):
1) M x s ≤ 0.2 x T x i + Z x (d+i)
2) M ≤ 0.3T
Consequently, the minimum ballast required is:
Z min = (M x s - 0.2 x T x i)/ (d+i)
To determine the appropriate characteristics of the ballast, refer to the manual of the tractor.
