This contribution is aimed to the design penetration device which operates hydraulically and would be mounted on the three-point hitch of a tractor. The system uses several force sensors associated with measuring and control unit. Measuring equipment is supplemented by a measurement system for measuring the position of the probe and the GPS system for defining the position of measurement in field. Before the field experiment it was undertaken a laboratory measurement to verify the mechanical and electronic parts. Comparison of results of measurements by manual and hydraulic equipment shows less than 10% difference, but differences between the measured resistance values of each sensor are larger and it will be needed to make another series of measurements to ascertain the cause of that fact.
