The VS uses the following technical equipment:


Vallerani System Delfino 3s

Vallerani System Delfino 3s

The Delfino 3s is composed of a single reversible mouldboard and a ripper.
According to soil and rainfall characteristics and to the projects’ objectives, the depth and length of work of ripper and mouldboard as well as the type of underground movement can be adjusted. Other adjustments can be done for a wide range of needs.

The single reversible mouldboard digs, thanks to its wave motion, micro basins 3,5m – 5m long, 40-50 cm wide and 40-50 cm deep.

The ripper, located in front of the plough, cracks and loosens up the soil at a depth of 60-70cm. It creates an ongoing underground splitted furrow which collects the water from the adjoining micro basins. 
The ripper does not reverse the upper soil and protects the ploughshare from braking.

The motion and the reversibility of the ploughshare are obtained by a hydraulic system.

The reversibility of the ploughshare allows an efficient work to promote the entry of run-off while working along the contour. It avoids empty returns.
In all configurations, the technical characteristics of the Delfino 3s and the speed of the tractor brake and crack the compact soil, facilitating deep infiltration of rainwater and roots growth. This water is thus protected from evaporation.
The rainwater, top soil, seeds, organic materials transported by wind and run-off accumulate in the micro basins and along the ripper tilling line boosting a longlasting regeneration process.

Each motion unit (mu) micro basin / underground splited furrow collects even in case of very low rainfall (150-500mm/year) up to 1000-1200 lt of water ( run-off water included).

 For further information please see the technical sheet.



Given the characteristics of the soil and the type of processing carried out with Delfino 3s, a 180-210 HP four-wheel drive tractor with a weight of 8-10 tons is required.

For further information please see the technical sheet.

Older equipment (no longer in production)

Trattore Delfino
Delfino” plow which digs crescents or micro-basins at the speed of 10/20 per minute. These micro basins are connected to each other by a 2 m long tracks left by a ripper working at a depth of 60 cm. The micro-basins have the average width of 60cm and are 5m long.

Even with very low rainfall (200-500mm/anno) each micro-basin can collect up to 1000 liters of water, including runoff.

Trattore Treno
The “Treno” plow digs a continuous furrow subdivided by diaphragms 60 cm width consisting of the topsoil scraped off by a purposed built mechanism to leave the most fertile ground for the plants and so that the rainwater does not flow but rather filters into the soil. It is particularly suitable for plain terrains and for the improvement of the crop production as well as for planting trees or shrubs for reforestation, for orchards and for creating windbreak lines.
