The efficiency of milled peat extraction is largely determined by the quality of the surface of the extraction fields – peat production fields. During the operation of technological equipment, due to the development of the central part of the field, near-channel edges are formed along the edges – areas with an elevated relief 25–50 cm wide. They make it difficult to remove rain and melt water, and negatively affect the performance of technological equipment. In TvSTU, work is underway to develop a high-performance edge cutter that could cut both channel edges in one pass, unlike the Finnish prototype PRF-240, which processes only one edge in one pass. One of the main issues when creating a brow cutter is to find the optimal angle of installation of the cutters in the transverse plane, since the machine should not throw peat chips into the peat production field channels. To justify the installation angle of the cutters, a complex laboratory experiment was carried out, which showed that the optimal installation angle of the cutters is 20º.
