Abstract

According to laboratory experiences with experimental self cleaning off fertilizer distributors, conducted by the method of planning of full factorial experiments, mathematical models of the second order, sufficiently describing dependences of unevenness and instability of seeding from constructive and technological parameters. As a result of the analysis optimum values of specified models are specified. The analysisof these modelsrefinedtheir optimumvalues the calibrationgap-6.6mm, the rigidity of the spring - rad
