Improvements in rotary machine tools for crops, essentially characterized by the fact that the tubular shaft carrying the rotating blades is related to the transmissible elements through a telescopic set composed of the shaft itself and an extension of the axis of the corresponding transmission sprocket, which is housed in said tubular body and whose extension constitutes a quadrangular core whose vertices are cut according to arcs of circle of equal radius with center on the axis of the section for its proper fit in the shaft hollow shaft carrier of blades which, with such a motive, can move axially at will.
