As required, remove the hexagonal screw and adjust the worn blade one hole
downwards. Lock again with the hexagonal screw. If the wing part “A” has worn thin, it
must be changed. A weldable consumable part is available - as for more information
from your distributor or from the original manufacturer.
Laser coulters have single-disc fertilizer coulters, which have the advantage of not
becoming blocked, such as in light tillage conditions. One requirement for the trouble-
free function of the laser coulter is that the gap between the scraper and the disc is so
small as possible. The disc can touch lightly to the scraper while rotating.

Seed coulters
Seed coulters consist of a coulter tube and tip part. The major seed drill types include
drag coulters and disc coulters. These coulter types incorporate the same tube
component. Changing the tip is a relatively fast task, which means that the machine can
be adjusted to a variety of different conditions as required by acquiring the required
coulter set.
Drag coulters can be used under most conditions. The most suitable applications are
found in clay areas where plowing is the form of basic tillage. Because of its flexibility,
the coulter is not likely to become blocked. Drag coulters are also available fitted with an
aluminum oxide or ceramic tip, which increases tip durability approximately ten-fold
compared to a cast tip.
Disc coulters are recommended for conditions where plant waste occurs in significant
amounts. Disc coulters are also suitable for general use (i.e. minimal tillage and
cultivation without plow).
