4.14 MARKER ARM ADJUSTMENT
4.14.1 LATERAL ADJUSTMENT
Adjust the bout markers so that the distance between the centre line of the seed drill and the
marking scraper is equal to the working width of the machine. This adjustment is approximate.
To avoid double‐seeding or non‐seeding, which may occur for example if the driver sits at an
angle in certain tractors, a follow‐up check should be done in the field. Depending on the type
of tractor and the driver position, the mark may be observed differently.
Adjust as follows:
1. Loosen the bolts in (A), SEE FIGURE 4.24.
2. Move the shaft sideways. If necessary the shaft can also be twisted to adjust the angle of tilt
of the marker wheel. The marker wheel should cut a clearly visible groove, but its angle of
attack must not be exaggerated. A larger angle of attack will exert greater strain on the parts.
3. Tighten the bolts (A). Retighten after several hours of use.
