Adjustments and operations
IMPORTANT
• To start the harrowing, we recommend using an average opening in
the disc gangs and in the holes of the drawbar plates. Adjust it, if
necessary.
• The harrowed soil is always on the left hand side of the operator
(harrow closed side).
•
Try to make a good finish between passes. Avoid the formation of
furrows or untilled strips.
• The tractor and harrow drawbar should be as aligned as possible
related to the work direction.
Tractor position related to the previous pass - Lateral displacement
The lateral displacement is
used to better position the tractor
regarding the previous furrow,
avoiding leaving a trace and giving
a reference to the operator.
This position is obtained
according to the tractor gauge and
cutting width of the harrow.
Whenever possible, the
tractor should pass over the
unworked soil and near the
previous furrow.
The displacement is done by
changing the drawbar in the hitch
bar, as follows:
Normal position (as shown above): used on
most situations.
Position 1: allows the tractor to get closer to
the previous furrow.
Position 2 and 3: allows the tractor to move
away from the previous furrow.
2) Drawbar angle
The holes (B) in the upper and
lower plates determine a greater
or smaller cutting width, and also
performs a small lateral displacement
of the harrow.
In normal working conditions, the
drawbar must operate on the central
hole of the upper and lower plates.
