Abstract: The relevance of the work is due to the need to control quality of sod peat produced in field conditions. This allows us to make timely any necessary changes to the design of mining machines and their mode of operation. One of the most important indicators of the quality of sod peat is its resistance to bending. The aim of the work is to create mechanical benchto control the sod peat flexural strength and to develop the methods of its application in practice. To achieve the objective, theoretical and experimental research methods were applied in development and manufacturing of the bench, the laboratory production of peat and the determination of sod peat flexural strength. As a result, the technique of using the bench was developed, the information about the impact of the speed rotation of the moulding screw on the bending strength was obtained, and the operating mode parameters were substantiated for the screw press of milling-forming and peat spreader machines. Unlike hydraulic equipment, the bench described in the work has greater sensitivity, it is less metal and cost consuming, and its equipping with modern digital dynamometer contributes to greater informativeness. Practical application of the described equipment makes it possible to organize rational mode of operation forsod peat producing machines.
