C.6 Adjusting the drop point
By altering the drop point, the working width can be accurately set and adjust-
ments to different fertiliser types can be made.
Check the setting of the drop point at the start of each working season, and during
the season if necessary (if uneven spreading is noticed).
The drop point is set using the top scale arc.
Figure 24: Checking the drop point
Checking:
1. Set the drop point to position 6.
2. Remove both outlets along with their brushes at both openings.
3. Release both plastic levers (agitator drive) and slide them downwards until
the splines of the agitator are showing.
4. Attach a suitably thin string at the rear in the direction of travel to the splines
of the agitator shafts and tauten it.
The triangular mark on the base plate must be aligned to the taut string.
If the mark is not aligned to the string, the drop point must be readjusted.
5. Only for machines with VariSpread: Recalibrate the drop point positions with
the operating unit.
NOTICE
The drop point must be set to the same position on both sides. Therefore, al-
ways check both settings.
NOTICE
Please follow the instructions in the chapter “Test/Diagnosis" of the operating
unit operator’s manual.
