The point or “chisel” is protected against wear by a hard metal plate (tungsten carbide cobalt plate) at the front - this means that this point has an especially long life. This is yet another AMAZONE invention which is often “imitated”. It is easily recognisable: The AMAZONE chisel opener is the result of years of experience and is simply very good.
A coulter chisel opener set with 2 hard-faced plates for a longer service life, e.g. for sandy soils, is available as an option.
AMAZONE also offers a chisel opener set for band sowing across a width of approx. 55 mm for conventional and mulch sowing. This set allows a wider distribution e.g. for increased tillering.
The duckfoot chisel opener set, in widths of 150 mm or 200 mm, is ideal for the band sowing at a shallow placement of, for example, fibre flax. With a coulter spacing of 18.75 cm, the 150 mm wide duckfoot coulter achieves almost full-surface weed control, whereas the 200 mm wide duckfoot coulter achieves complete mechanical weed control like a shallow cultivator. In this respect, the pulling power required for the narrow duckfoot coulter is less than for the 200 mm wide duckfoot coulter.
