Variable width ploughs are able to grant a continuous set-up of bodies working width, 1st body inclusive. In-fact the arm holding the tools change automatically the soil entrance of both the 1st body and the rear ones, this will avoid waste of time to regulate the plough.

By EMMEGIEMME hydropneumatic system it's possible to regulate at best (using the hydraulic trucks system) the share stress allowing the body to arise when it finds an hidden obstacle and consequently enter again very quickly on the soil as soon as the obstacle is passed.
