An executive device of bulldozer includes rotary blade, pushers, frame and control mechanism of blade turn in plan. In the mechanism for control of blade turn in plan elastic elements are used, those give possibility for the blade to deflect with self-adaptation by angle &phgr; from 0° to 5°, this leads to vibrational motion with intensifying effect coming to existence, those promote as well improvement of collecting ability of the blade. |
