FIELD: agriculture; machine building.
SUBSTANCE: invention relates to the field of agricultural machine building, in particular to designs of measuring instruments for studying of working load of tillage tools. Device comprises a soil channel with a movable working member mounted on a bogie with a frame, and measuring links. Device is equipped with additional rectangular frame, to which free ends of tensobeams are hingedly attached by means of intermediate links. Second ends of tensobeams are rigidly fixed on bogie frame. Measuring links are made in the form of tensometric beams and installed in three mutually perpendicular planes parallel to vertical, horizontal and lateral measured forces. Longitudinal planes of tensobeams are parallel to planes, in which there are determined forces. Points of attachment to frame of intermediate links are located in one plane.
EFFECT: high accuracy of measuring forces on working elements of hinged agricultural tools in three directions.
