The article considers the questions of efficiency of work of snowplows, equipped with plough work tools. Authors are encouraged to make energy efficiency assessment of work of plough work tools of the snow-removing machines, equipped with suspension with different form factors. The dependence between the size of the fluctuations of the work tool and the friction force acting on the bottom edge of the blade allows estimating the cost of moving the snow from the road surface and the maximum height of the remaining snow or its’ total amount left on the road. It has been regarded the subproblem to definite the efficiency - the ratio of the forces of the resistance movement of the blade to the maximum height of snow left on the surface of the road, after passing the snow-removing machine. It has been shown for the first time the calculated dependence of this parameter for different designs of work tools suspension. The result of calculation is given, according to which the conditions of rational use of any type of suspension of the working body are identified.
