First furrow-slice adjustment
The width of the first furrow
-
slice should correspond to
the width of the other furrow
-
slices, however the
following should be taken into account too:
•
resultant compensation of the plough’s operating
resistance,
•
while using broad tractor tyres, the width of the first
furrow
-
slice should be reduced to ensure proper fitting to
the front furrow
-
slices,
•
while using a plough equipped with a furrow widener, the
width of the first furrow
-
slice should be reduced in
relation to the width of the other furrow
-
slices.
After altering the first furrow
-
slice width, an adjustment of the ploughing width may be
required.

Levelling
The plough is longitudinally levelled by means of the upper fastener. The plough frame
should always be parallel to the ground. The upper fastener bolt should be in the middle
of the longitudinal hole.
The plough is adjusted transversely using the bolts with handles. The adjustments for the
left and right sides are done separately. Looking from the rear of the plough, the plough
beams should be positioned perpendicularly to the ground. As the working depth changes,
a correction of the transverse levelling must be made.
