The developed design of two-drum mounted implements of the trailed organic fertilizer spreader PRT-10 significantly enhances its technological capabilities in the mechanization of composting. The experimental design is installed on an organic fertilizer spreader and consists of a lower and upper milling drum type. The upper beater is displaced from the lower axis by ± 400 mm. The range of the values of the research factors is chosen: the time-tota of rotation of the upper and lower biters: 170-490 min^-1, and the linear velocities of the transporter – 0.05...0.25 m/s. The simulation was carried out according to the BoxBencin plan with a total number of experiments of 27. The main criteria of work are: uniformity in humidity, throughput, energy consumption. Using Mathematica software package, the approximation of the data obtained, which resulted in an equation for the dependence of the power and homogeneity of the mixture on the study factors. As a result of experimental studies of the hook-up Reiser, the PRT-10 fertilizer with two-drum attachment is based on the dependence of the mean value of the stitching power P and the uniformity of the pus-compost mixture δW on the rotational speeds of the lower and upper working bodies n₁, n₂, mixture (the speed of the conveyor PRT-10) V and the spread of the upper working body relative to the lower L. The optimal design and technological parameters of the device developed as a result of the water of the compromise task, and to ensure the most homogeneous pus-compost mixture with low energy losses: n₁ = 320 rpm, n₂ = 170 rpm, V = 0.05 m/s, L = -0.4 m. The homogeneity of the pus-compost mixture was δ = 0.88, and the power consumption P = 3.34 kW.
