Cutting depth
Tractor position related to the previous pass - lateral displacement
2) Drawbar angle
The holes (A) in the upper and lower plates
determine a greater or smaller cutting width
and also performs the lateral displacement of
the harrow.
In normal conditions, the drawbar should
operate in the central hole of the fixation plates.
Normal position: Used on most situations.
Position #1: allows the tractor to approach the
previous furrow.
Position #2: allows the tractor to move away from
the previous furrow.
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.
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:
