2.28 Scraper
Figure 2.75
The scraper default settings are shown in the figure.
The scraper position can be adjusted in two places. If the setting (A) is insufficient, the holder (B)
can be adjusted lengthwise.
NOTE!
The distance (C) between the scraper blade and the tyre must not be less than 5 mm. Rotate
the tyre by hand to verify that this distance is not less than 5 mm at any point.
!
Depending on the circumstances, a larger distance (C) may be required for optimum results. If
the scraper does not operate satisfactorily, then try with different scraper settings.
Example:
- If there are a lot of plant residues in the soil and it is humid, the scraper will usually provide
better results when the distance (C) is increased to approx. 20 mm.
- If the soil is humid without plant residues, the scraper will provide better results when mount-
ed in the default position (C = 5 mm).
