Abstract
A multipurpose machine for close-row production of tree or shrub plantations, such as vineyards or orchards includes a working head including a rotor powered by a motor and designed for receiving at least two interchangeable tools. The invention also includes a meshing guide peripherally configured to mesh with the foot of trees or shrubs and arranged above the tools, the meshing guide being capable of rotating at a speed different from that of the rotor and having, viewed from the direction of said axis, the general shape of a notched disc having at its periphery alternating notches and projecting parts, the length of the operating radius of the rotary tools being not more than that of the radius of a circle tangent to the base of the notches of the guide, which can thereby, in operation, successively mesh with the base of the trees or shrubs, when coming in contact with the latter.
