4.8 ROLLER ADJUSTMENT COMBI VERSION

By pins
This type of adjustment allows you to work in two distinct ways.
1) Fixed tilling depth:
After having established the most suitable tilling depth, set the
pins (1 e 2 fi g.61) in the holes immediately above and below
the roller connecting arm (3 fi g.61). This allows the knives of
the implement to dig into the soil and work it at a constant depth
maintained by the position of the pins, which guarantee the fi xed
roller setting.
2) Variable tilling depth (swinging):
Unlike the previous method, the pin is either not needed (2
fi g.62) or can be set in the highest holes, so as to allow the arm
to swing to a certain extent (3 fi g.62).
As the arm can move (3 fi g.62), the machine can ride over any
obstructions encountered during the tillage operations without
the roller being damaged, as the actual arm moves within the
swinging range established by the positions of the pin (1 fi g.62),
since it is no longer blocked by these latter.
Moreover, the advantage of «variable depth» tillage is that it
obtains a more or less uniform soil working level both at the
beginning and end, since the implement digs into the soil at the
beginning as gradually as it raises at the end.
ATTENTION
In case of use of pin adjustment with COMBI power harrows (fi g.63),
using rollers packer 500, fl anged 500 and rubber 500, it is recom-
mended not to remove the bolt (1 fi g.63); while using rollers packer
600,rubber 600 it is advisable to remove the bolt (1 fi g.63) to allow
a greater working depth. In case of fi xed tilling depth, with any type
of roller, change the position of pin (2 fi g.63) according to the wear
of the knives, to keep a constant working height and to avoid the
entrainment of the sowing elements (in case of combination with
seeder )

4.9 COMBINED MACHINE WITH SEED DRILL

The harrow can work in combination with the seed drill.
First and foremost, thoroughly check to make sure that the ma-
chine can be used with the seed drill, then check that the seed drill
has been assembled correctly, the right way and that there is no
interference with the hydraulic pipes.
The «Work depth» can only be regulated with pins in this combi-
nation.
For information on coupling the seed drill to the equipment,
refer to the operation manual of the seeder.

4.10 LEVELLING BAR

This is situated between the roller and harrow (1 fi g.64) and is fi xed
to the roller-bearing sides with 2 pins (2 fi g.64).
It allows already tilled soil to be levelled and refi ned to a further
extent before the roller passes over the ground.
The levelling bar can be regulated by operating the rams (1 fi g.64),
which are installed on the front beam of the roller.
The best position is 4 to 5 cm higher than the roller bearing posi-
tion (fi g.64).
Since the position is fi xed with pins, the adjusting movement is
circular and when the levelling bar lowers, it nears the ground in
an oblique position, thus facilitating the fl ow of soil under the action
of the levelling roller
