Settings at the
seeding heart
Make the following adjustments only at the first sowing unit, at first.
The adjustments cannot be carried over to the other seed rows until
you have made and checked the following adjustments on the first
seed row.
Prerequisites for subsequent work:
•
Seed hopper of the first seed row filled with seed
•
Fan running at corresponding PTO speed
•
Negative pressure and overpressure adjusted to suit seed and
seed disc
•
Flat catch pan placed under the first seed row
Setting the scrapers
At the seeding heart, the seed can be monitored on the seed disc.
Each hole should be occupied by exactly one grain.
Depending on the seed, the correct position of the scraper has to be
determined. A general rule is:
> Turn the drive wheel to drive the seeding heart. The seed now falls
into the flat catch pan.
> Move the scraper carefully and find the correct setting
Adjusting the additional
scraper [+]
For special types of seed, it may be necessary to adjust an additional
scraper.
> Move the scraper carefully and find the correct setting. Twin seed
rows require the adjustment of two additional scrapers.
