FIELD: test equipment.
SUBSTANCE: invention refers to triboengineering. Device includes capacity with abrasive medium - soil, which is fixed on machine bed with possibility of being moved in longitudinal and transverse directions. Shaft with specimens fixed at certain angle to soil movement direction so that it can be submerged into soil through the value subject to strengthening impacts. Machine and shaft has the possibility of installing the longitudinal slide feed of the machine and with possibility of setting the shaft rotation speed which corresponds to linear movement speed of working member at soil cultivation.
EFFECT: simplifying the design and simplifying the test performance.
