ADJUSTMENTS
CAUTION:
Read this chapter in its entirety to properly
understand all adjustments, the correct order and
procedures before starting work.
CAUTION:
Perform only one adjustment at a time.
9.1 Use in the field
ʈ

IMPORTANT:
For an optimum result, the working speed must be
between 5 and 7 km/h (3 and 4.5 mph).
A higher speed may cause rapid wear of the working
parts.

ʈ
Do not make sharp turns when the implement is in the ground.

Reduce speed when turning or when clearing obstacles

With a new implement or at the beginning of each new season
and for best results, it may be necessary to perform several
return runs. With each pass, the mould boards are better
polished, the soil slides more easily and settings can be

9.2 First
pass
For the 1st pass, the tractor is not in the furrow. This may change

9.2.1 Ground
work
ʈ
Drive forwards slowly and lower the implement for a gradual
entry of the bodies into the soil.
9.2.2 Alignment
adjustment
To adjust the alignment:
ʈ
7KHWUDFWRUVVWDELOLVHUVPXVWEHIUHHVHH
ʈ
The top link must be in line behind of the tractor.
-
Top link is too far towards the ploughed side:
Tighten the nut on the adjustment screw to align the
implement with the draught line of the tractor
-
Top link is too far towards the unploughed side:
Loosen the nut on the adjustment screw to align the
implement with the draught line of the tractor
9.2.3
Working depth adjustment
The working depth is controlled by:
ʈ
The height of the tractor's hydraulic lifting mechanism for the
front of the implement.
ʈ
The height of the gauge wheel for the rear of the implement.

Setting the tractor draught control system
Set the tractor draught control to minimum sensitivity. The
working depth of the 1st plough body will be constant. Once
adjustment is completed, increase the sensitivity to optimise the
tractor's grip.
IMPORTANT:
Under adverse conditions (sodden ground, tractor
power limit, etc.) it is not possible to work with the
draught control set to minimum sensitivity. In this
case, account should be taken of lifting mechanism
reactions to estimate the average depth..

9.3.1 Alignment
adjustment
The alignment is correctly set when
-
The implement is in line behind the tractor.
-

-
The landsides should not apply unnecessary force to the
ploughing face.
Otherwise, re-adjust the alignment of the implement.
