Seed coulters
Description of the seed coulters
-
The seed is sown with the coulters.
-
The coulter discs (2) cut through the seedbed and expose the seed grove.
-
The seed is stored between the discs (2).
-
The pressure wheel (5) guides the seed coulter and closes the groove.
-
The harrow (6) covers the sowing row with soil and levels the soil.
-
The coulter is stored in maintenance-free rubber bearings.
Coulter discs
-
The discs are located at the front, are V-shaped for each other for low tensile strength and the
formation of a groove for seed placement.
Disk adjustment
-
In case of wear the seed discs, it is necessary to adjust the
distance between the discs by changing the location of the
spacers.
-
All 4 spacers (1) must always be used on each coulter. If all 4
spacers (1) are not used
–
the coulter will be damaged.
-
The discs must be slightly pretensioned on the blade.
However, it must be possible to turn them easily.
-
When rotating one disc, the other must be rotated reliable.
-
If the discs stop or lock due to incorrect preload, the seed will
start to aggregate.
