In the electro-hydraulic version, the choice of the width of the work and the use of all or part of the tools of which it is equipped, is carried out from the control box in the tractor (without any manual intervention).
Each hydraulic cylinder can be equipped with a safety device with hydraulic re-engagement, (Same system that equips our autonomous intervine device).
One example among others: The "Domaine de CAZES" in Rivesaltes (our photo), a vineyard of 210 hectares with a part in 2m50 width cultivated completelly, and the other with 3m weeded over 1m. To pass from the 1st to the 2nd, simply raise the central tool(s) and widen the frame by 0.25m on each side keeping the respective position of the lateral tools. The inverse operation is carried out to return to the width of 2m50.
The economical version offers to carry out the retraction of the tools manually by use of a simple pin.´╗┐
