This agricultural machine is a Jean-Claude Lagrange vineyard plough which serves to clean the vine stock without damaging it, by means of ploughshares and brushes located laterally on either side of the machine. It is actuated by the (very sensitive) feeler with electric contacts which can be adjusted in terms of height, advance and return. With the aid of the hydraulic system which controls it it has an advantage in the progressive retraction of all its elements. It follows the gradient of the slope by the action of a jacking system. An electric system controlled by a box acts on the hydraulic system. The whole thing is actuated with the aid of a variable output pump.
