Abstract: The present invention relates to a machine for digging into the lower layers of the ground, wherein said machine comprises the following members: a base frame (1), a ground excavator (2) and a driving chain-type working organ (3) that is suspended from the frame (1) by a device (4) so as to be capable of forced rotation about two geometrical axes (17, 18). During operation of the machine, the axis (17) is perpendicular to the support surface (5) of the drive section (6) of the frame (1), while the axis (18 ) is parallel to the longitudinal axis (a—a) of said drive section (6). During operation, the rotation of the working organ (3) about the two axes (17, 18) makes it possible to dig excavations with a bottom that is horizontal or has a predetermined lateral inclination while maintaining an important width, to form sloped excavations or to dig excavations having various profiles.
