CHERVONETS-8 – Pre-sowing cultivator

A semi-trailed seedbed cultivator with an 8 m working width. Its 65 sweeps on S-shaped shanks loosen the soil to a depth of 3–15 cm and prepare the seedbed in one pass; it needs a tractor of 150 hp or more. Output is up to 9 ha/h.

The S-shaped spring shank creates a suitable air and moisture regime in the soil worked by the cultivator. Because the shank deforms elastically, the sweep oscillates in the soil. It vibrates along the direction of travel and sideways, with practically no vertical movement. This lets the machine work strictly to the set depth, improves crumbling, lowers draught resistance and keeps the tool from clogging with soil and plant material. The working tools sit 12.5 cm apart, which gives high-quality work on the fertile layer along the whole width of the cultivator.

Even distribution of the machine's pressure on the soil gives the best crumbling and levelling. It comes from the swinging suspension, the double toothed rollers (front 33 cm, rear 27 cm) and the way the rollers are staggered one behind the other. The working depth of the tools is adjusted quickly by hand without extra tools, which cuts setting-up time and raises the machine's output overall.
