“Active soil cultivation” refers to soil cultivation performed by a machine equipped with implements and driven by the power take-off shaft of a tractor.
Power harrows manufactured by Breviglieri are all PTO-driven and consist of a series of bladed rotors which counter-rotate about a vertical axis.
They can also be fitted with different types of rear rollers, which help the harrow follow the contours of the ground and enable the working depth to be adjusted.
Power harrows finely break up the soil, refining and evenly distributing it over the entire working width to create a perfect seed bed: they are generally used for secondary tillage after ploughing or subsoiling and can break up even the most compacted ground, often in a single pass.
These machines are highly recommended from an agronomic point of view: they enable an extremely high crop yield since they do not invert soil layers, but rather help to maintain the soil’s natural composition, structure and biodiversity.
Furthermore these implements are most frequently used in combination with all types of seed drill, for soil cultivation and seeding in a single pass to limit operating costs, while preventing excessive soil compaction caused by repeated passes of the tractor.
