RANGE SPER81 | SPERW8 SEMI-MOUNTED REVERSIBLE PLOUGHS FROM 6 TO 10 FURROWS

SPER81 Semi-mounted reversible ploughs From 6 to 8 furrows | Adjustable working width by bolts The SPER 81, profits from the whole of the technological profits of Varilibre. This plough is designed to combine, the technology of the VARILIBRE by offering a great simplification of use. The SPER81 offers an adjustment of working width from 12 to 20’’, a reversal system by double cylinders and excellent ground contour following. Pivoted headstock Double cylinder turnover system Fixed cat. With the same lifting bar Linkage pins in a clevis 110° turning angle Manoeuvrability and headlands shortened....

From 6 to 8 furrows Hydraulic bogie assembled on hydropneumatic suspension Adjustable work width: work width from 12 to 20 ‘’ Articulation of the frame Front/Rear in automatic Lock/Unlock The point of traction of the furrow is with the vertical of the mouldboard, it allows the balance of the side forces on the furrow. Offset elements Adjustable working width Wheel position optimized. • Less pressure on landside = less power needed • Lateral forces reduced • Wearing parts reduced Equal forces : • On furrows • On safety device ball bearings 5 working width : 12-14-16-18-20’’ Adjustable working...

SPERW 8, the VARILIBRE Semi-mounted reversible ploughs From 7 to 10 furrows | Hydraulic adjustable working width The VARILIBRE is without any doubt the most technological semimounted plough on the market. The study of the forces on the furrow led our engineers to re-examine the kinematics of the beams. System VARILIBRE, the alliance of the common sense and technology. The concept: To draw the furrow by a point of pivot, with the whole of the side forces which balance to plough straight. The constraint: to change the position of the traction point in the furrow. Profits: of traction, consumption,...

1 Natural alignment of the elements in the direction of the ploughing • No useless lateral confining pressures. • Reduction of the landside wear rate. • Reduction of the power of traction necessary for a furrows equivalent number. 2 Natural avoiding obstacles • Less stone hauled. • Increased handiness as well with work as with transport. 3 Adaptation of the work width • Versatility of the plough according to the power available. • Versatility of the plough according to the climatic conditions and the soil. • Ex: in 8 furrows, one ploughing of 2,40m in 12’’ with 4,10m in 20’’. 4 The last furrow...
