In this paper, the driving mechanism of the soil digging machine operating element is analyzed from the point of view of geometry and kinetics. It is an articulated quadrangle, of which leading element is the shaft crankpin. The paper determines the parameters specific to the plane parallel motion-paths, rates which ascertain the mode of operation of the mattock and of the soil digging machine with driving elements in plane motion.
