Selection of disks
Never drill out disks in order to increase the diameter of the intake holes, otherwise serious deterioration of sowing accuracy may result.
For Maize seeds
In general, use disks with holes of diameter 5 mm (0.2 ’’) for maximum versatility (Standard supplied).
Maize seeds with very angular or pointed shapes can be sown with a disk with 4.5 mm (0.17 ’’) diameter holes to improve seed placement in the row.
Precision Seed Drills
MAXIMA 2
For sowing very large maize seeds, we recommend using a disk with 5.5 mm (0.21 ’’) diameter holes.
For sowing very small sweet corn seeds, we recommend using a disk with 3.5 mm (0.14 ’’) diameter holes.
For Sunflower seeds
Successful sunflower sowing depends on two factors:
- The adaptation of the disk hole diameter to the seed size.
- The selector adjustment.
Indications on the seed bags do not mention the seed size.
We recommend to possess 2 disk models (holes diameter 2.5 mm (0.1 ’’) and 3.5 mm (0.14 ’’)) if the seed size to be purchased cannot be specified.
