METERING ADJUSTMENT
Two factors influence the degree of seed:
1.The position of the seed scraper in relation
to the holes of the disc. It is therefore
necessary to adjust the eight of the scraper
as needed for each seed type.
2.The degree of suction (depression) at the
seed disc. It is therefore necessary to adjust
the degree of suction to the weight of the
seed to be planted;
Fig.36
The (patented) MONOSEM system allows a
unique adjustment (fig. 36-37).
• To adjust the height of the scraper
and at the same time
• To adapt the degree of suction to the
weight and size of the seed.
Fig.37
When the indicator 1 is positioned to the “+”
(fig 36) it raises the scraper over the holes of
the disc and increases the degree of suction
(closing the size of the hole 2) . This may
cause doubles if raised too high.
When the indicator 1 is positioned to (fig 37).
It lower the scraper over the holes and
reduces the degree of suction (opening the
size of the hole 2) . This may cause skipping
if too low.
A control window in the cover allows you to
monitor the results.
