A machine and method utilize a tracked undercarriage including a frame with a central body, front and rear transverse assemblies connected to the central body and extending on opposite sides. Each of a pair of lateral tracks is connected, at the front and at the rear, to ends of the transverse assemblies. The base machine includes excavation equipment having different working positions/configurations. Each of a pair of front load cells of the tracked undercarriage is mounted between a lateral track and the front transverse assembly. Each of a pair of rear load cells is mounted between a lateral track and the rear transverse assembly. Each load cell detects force data indicating the reaction force exerted between the associated lateral track and the respective transverse assembly. A control system computes a barycentre planar position of the machine situated substantially at a reference plane computed as a function of the force data.
