In the paper chosen problems of dynamics of caterpillar finger in an open metal seven eyelet hinge is described. A low reliability of the caterpillar chains seems to be a consequence of design proces s of agricultural tractors. For this reason, dynamic calculation of the caterpillar finger of tractor is presented. Probe is spent on tractor VT - 150 manufactures TK "VgTz" having caterpillars with seven eyelets cast track in a mode of correction of the set direction of working-class movement on plough. In the paper example results of theoretical and experimental researches is presented. Results of the study experimental of the dynamics loads in caterpillar finger of the tractor with plow have shown that it is possible his consideration as springy symmetric steel peg on two steel full tilts. Analysis of usage of the agricultural caterpillar tractors and results of calculations confirm that the dynamics calculations are more exact then previous assumptions. New recommendations to caterpillars constructors are put in order to increase tractors reliability. The frequency of caterpillar finger should be enlarged by increasing of his acerbity. In the paper, a new set of main parameters of VT — 150 caterpillar fingers is presented in comparison with nominal one.
