8. Adjustments and operations
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.
Position #1: Normal position (centered): Used in most situations.
Position #2: Allows the tractor to approach the previous furrow.
2) Drawbar angle
The holes (A) in the upper and lower
plates define a greater or smaller cutting depth
and also performs the lateral displacement
of the disk harrow.
In normal conditions, the drawbar
should operate in the central hole of the
fixation plates.
Cutting depth
- To start the harrowing, we recommend using an average opening in the disc gangs
and in the holes of the drawbar plates.
- 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 equipment drawbar should be as aligned as possible related to the
work direction.

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.
