Checking the seed
disc
For the different seeds appropriate seed discs are available. Check
before starting to sow, whether the correct seed disc is installed.
> Loosen and remove the nuts
> Remove the lid of the seeding heart along with the seed hopper
Marking of seed discs
The seed discs are marked with 4 or 5 numerical digits. The first two
or three digits refer to the number of holes in the seed disc. The last
two digits always refer to the diameter of the holes:
Example:
The seed disc is marked with 8008.
80 = 80 holes in seed disc
08 = 0.8 mm diameter of holes
Which seed disc is suitable for which seed can be determined from the
table on the next page. However, the values in the table are provided
for guidance only. The calibration and form of the seed depend on:
•
Type
•
Growth pattern
•
Manufacturer
The number of holes in the seed disc determines the spacing between
crops in the seed row. The following table is a reference:
