The VS uses the following technical equipment:


The new Delfino³ plow has a single reversible plowshare which through a wave motion digs crescents or micro basins 5 meters long, 50 cm deep and spaced about 2 m . Even with very low rainfall (150-500mm/year) each micro basin/collection bag can collect over 1500 litres of water, including runoff.

Two ripper placed before the back labor body work the soil to a depth of 80 cm. Rise at the crescent and descend between the crescents. Thus to attain, in the stretch of land between the crescent, a collection bag which receives water from the crescents itself. This water is protected against evaporation and remains available to plant roots and groundwater. The two rippers are staggered so as to move any surface stone.

Weight of the plow: approx 2.000kg.




A 240 hp tractor wheels fitted with wide forestation tires, maximum ballast and hubs to enlarge the track.

The costs are always to be established with the manufacturers.

In order to ensure continuity of work is needed to order spare parts for an amount equal to about 10% of the cost of the plow and 5% of the cost of the tractor.

This equipment set, including the integrative instrumentation, which varies according to the terrain worked to increase productivity and reduce the workload for the individual, constitute the UMSV (mechanized unit of the Vallerani System).

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.
