TANDEM series was projected to exploit harvest residues to the best, so that it can become a natural fertilizer. The combination of its tools succeeds in working the soil intensively, at a minimum depth.
The discs are mounted on independent spring supports. It is possible to choose a cage roller, a paker roller, and a full-flex roller.
Trailed version give an important advantage: medium-power tractors and work with quite large machines (just see it in the table below).
The spring brings many benefits, namely their flexibility enables a wider movement while working on stony soils, on the other hand it let residues fall better, because it vibrates more that other support systems.
