The guidelines set out the application of machines and mechanisms for integrated mechanization of works in forestry and landscape gardening. Technologies of works in reforestation on cuttings, nurseries, on care cabins and in forest and garden-park farms are given . The issues of harvesting, cleaning and sorting of sowing material . are considered. The method of calculation of traction resistance of forest and gardening machines and their aggregation with tractors of different traction classes is given . The issues of studying the parameters of machines and mechanisms used in all types of work in forest and garden-park production are considered . The main characteristics of machines and mechanisms, the calculation of the replacement performance of machine-tractor units, the study of the patency of wheeled tractors, as well as the technical characteristics of serial wheeled and tracked tractors.
