The article discusses the skidding concept, types and methods. In addition to specialized skidding tractors (cable skidder, grapple skidder, with a pack grip, and forwarders), modern single-machine complexes for harvesting wood according to Canadian and Scandinavian cutting technologies are presented. A theoretical analysis of tractor skidding performance is carried out, namely: the influence of the average skidding distance and soil conditions is estimated; an assessment of the impact of the type of logging and the taxation characteristics of the stand is given; the influence of soil and terrain conditions is estimated; the impact of the operator's qualifications and working conditions is evaluated. Based on the analysis of literature sources and production experience in the field of logging operations, the expediency of changing the operating mode of operators, as well as the use of special application software packages that allow real-time evaluation of the efficiency of the skidding tractor and its technical condition is justified. The influence of the category of soil conditions and the presence of non-operational areas in the cutting area on the average skidding distance, other conditions being equal, is shown. The work was carried out within the framework of the scientific school "Innovative developments in the field of logging industry and forestry" of the Arctic State Agrotechnological University.

An analysis of modern technologies for pneumatic grain separation is provided. The necessity of increasing the efficiency of pneumatic separation of grain at all stages of its production, starting from the grain combine and ending with the operations of preparing grain for grinding, is substantiated. The main structural and technological reasons for the low efficiency of pneumatic separating systems have been identified. A method for determining the terminal velocity of grain in a portioned pneumatic classifier is presented. The process of pneumatic classification of seeds of cereals that have undergone full-flow seed processing technology has been studied. The basic physical laws for determining the speed of terminal velocity of grain in an ascending vertical air flow are substantiated. It has been established that seed material that has passed through the seed processing production line varies in terminal velocity.
