Considered the issue of improving the operational characteristics of trailing scraper through the use of a combined knife system, which combines in one machine the widespread speed stab system and shovels cutting on. Requirements are formulated to knife scraper systems and the new combined knife system. It allows you to develop soil in terms of minimum energy and the free cutting of the soil. The practical possibility of obtaining a smooth face, more intense filling of the bucket, rational distribution of soil in the bucket in conditions of free cutting and filling of the bucket when the increased cutting depth of soil, without additional machines. The obtained data on the value of the coefficient of the specific resistance to cutting when the width of the free cut in the range of 1.0 to 2.2 m. The recommendations for a rational distribution of the soil in the bucket during the free cutting.
