This three point (A) mounted machine, when hitched to a tractor of appropriate horsepower, has proven to be ideal for the elimination, in one pass, of stones and vegetable residues on the surface. The heart of the machine is the blade rotor (B), composed of specifically designed blades whose counter-rotation, throw stones, dirt, weeds and debris against the selection grill (C). The coarse material, stopped by the grill, falls in the trench made by the working depth of the rotor and is covered by the fine earth that passed through the selection grill and it is lightly pressed by the edge of the trailing board (D), forming a perfect seed bed with pressure controlled by the crank handle (E).
The selection grill (C), in addition of having the function of sifting the soil, allows the operator to work in especially heavy conditions. The vibrating system guarantees the constant cleaning of the spring tines even in conditions of moist or wet soil, obtaining the continuous flow of dirt.
Furthermore, the ability to change the working angle of the selection grill allows the operator to work more deeply with less power.
The working depth is adjustable from 10 to 30 cm according to the type of stone burier using a special system of pins (F) that determines the position of the rear roller (G).
The side discs (H) are positioned in front of the machine to greatly facilitate the penetration and depth by opening a narrow trench that keeps the shield for the side chain drive from dragging before the rotor.
The large choice of accessories available for the stone burier allow the operator to work in different sectors: creation and maintenance of green areas, horticulture, flower nurseries, golf course development and maintenance, remediation and inter-row weeding: vineyards-orchards-nurseries.
To allow the stone burier to work in such different soil’s conditions, Massano company has researched and developed two types of rotors:
Used to bury stones, vegetables residues such as roots, harvest remains and small sticks by means of specially designed tiller blades that, in the soil, pull out the stones and throw them against the selection grill.
The picture shows the rotor with the special tiller blades on the double flange.
Used to fracture and bury the hard clods present in especially dry soils with high clay content by means of special tools called blades which break up the clods and throw them against the selection grill.
