The machine is constructed as a tracked vehicle, in the form of a small digger (1), on a chassis (11), carrying the tracks (19) and a turret (14), mounted so as to pivot on the chassis. The turret carries an articulated arm (12), which is fitted at its outer extremity with a digging tool (3), for working the soil. At the opposite end of the turret is a drum (2), which is mounted so as to rotate around a horizontal axis. This horizontal axis is carried by an articulated arm bracket (13), which is linked to the vehicle chassis by means of a second horizontal axis. The angular position of the drum is adjustable in order to adjust the height of the drum, relative to the frame. The drum is constructed of a series of blades (21), which extend longitudinally, parallel to the axis of the drum and radiate towards the exterior of the drum.
