Agricultural tool-holder

An agricultural tool holder comprising:

• a central chassis adapted to support a three-point coupling system for coupling with an agricultural tractor, said central chassis housing hydraulic and electrical parts that actuate articulated components of the tool holder;
• at least one lateral chassis mounted so as to be slideable toward or away from said central chassis, wherein said central chassis has an axis of symmetry and comprises a parallel pair of tubular beams disposed orthogonal to the axis of symmetry of said central chassis, wherein said at least one lateral chassis has a parallel pair of rods respectively inserted and slidable within the parallel of tubular beams so as to telescopically support said at least one lateral chassis;
• and
• at least one actuator cooperative with said at least one lateral chassis so as to move said at least one lateral chassis, said at least one actuator being mounted on said central chassis, wherein the parallel pair of rods are rigidly connected by a pair of spacing bars, one sparing bar of the pair of spacing bars being interposed between the parallel pair of rods and screwed to the parallel pair of rods, another spacing bar of the pair of spacing bars being interposed between the parallel pair of rods and screwed of the parallel pair of rods at a center of the parallel pair of rods, the parallel pair of rods being inserted into the respective parallel pair of tubular beam by a section equal to approximately one-half of a length of the parallel pair of rods.
