Improvements in agricultural machines, equipped with variable height and exhaust mechanism for the tools, which are essentially characterized by the fact that the machine support wheels are mounted on the ground, on a vertically guided bar and to which a tie rod is articulated connected, on the other hand, to an elbow lever, articulated at its apex to an axis placed integral with the frame itself and joined, by the branch opposite that of connection with said arm, with a drilled and threaded oscillating die, inside the which passes a threaded or rotating spindle without possibility of axial displacement in a bearing, in turn articulated in a fixed support to the frame while, on the other, it ends in a driving crank for the ascent and descent of the bar-wheel assembly.
