Multifunctional machine for treatment of an agricultural field, preferably able to prepare the soil for the sowing, towed by a tractor, and characterized in that comprising:- a structure preferably electrically welded and made of section bars preferably made of steel that achieves a frame where additional elements of the same machine are connected- a series of working objects composed of a group of treatment tools, fixed all along the length and the width of a rotary horizontal axis, called rotor, placed on the lower side of the frame so that said working objects reach the ground- a towing bar connected at one end to said frame of the machine by using a proper first connection device and at the other end to a tractor by using a proper second connection devicewherein the connection of the towing bar to the frame of the machine includes a pivot in order to make the axis to rotate according to its use in a phase of transportation of the machine on the road the operator arranges the frame so that its longitudinal axis is aligned to the direction of motion, instead during the treatment of field the operator makes the frame to rotate of 90° so that the axis of the same frame results to be perpendicular to the direction of motion in such a way the treatment of large fields in a short time can be achieved and it is further possible an easy transportation of the machine on the road.
