The WICHER pre-sowing cultivator is a modern cultivation machine with working widths from 3 to 4.5 meters (the wind is additionally pulled in the 5.3 and 5.7 m version). The work of this aggregate can be divided into five stages:
1. Loosening of the tracks (ruts after the tractor has passed) with the conditioners with spring tension.
2. Crushing with the use of nine-string front rollers. The front and rear string rollers support the entire unit and are mounted on bearing units.
3. Loosening the soil: this activity is performed by reinforced tines of the cultivator type with the so-called 180 mm wide goose foot.
4. Fragmentation and leveling: at this stage, the main role is played by the rear string roller and the leveling board located directly behind it. The shaft breaks up lumps and lumps, ensuring a very good lumpy structure.
5. Compaction – secondary compaction and final preparation of the soil for sowing are performed by a pin roller with a diameter of 370 mm.
