1. A device for shear force tests, particularly for soil, in field conditions, which includes a tensometric metering system cooperating with a two-part shear set and with a carrying frame, whereas the carrying frame is suspended on a tractor three-point suspension system by means of pins and an upper joint, characterised in that it has an extensometer (tensometric) bar (8) attached on the transverse front bar (11) of the carrying frame (4) propped on runners (5), with a bumber (9) fitted on it, whereas rests on the upper arm of the two-arm lever (10), which rotatably sits on the transverse back bar (13) of the carrying frame (4) and which has a grip (14) attached to the lower arm, whereas the shear set (17) is fitted to that grip (14) with a strand (17).<IMAGE>
