Results of studies of the power of installed engines and the mass of self-propelled rod sprayers

Plant protection and the application of mineral fertilizers play an important role in production agricultural products. To improve technological processes develop new models self-propelled rod sprayers, it is advisable to determine laws distribution their technical parameters. A number power installed engines sprayers has a coefficient variation 30.4%, which indicates that close normal. For 95% considered value range 55.1 ... 225.3 kW. It changes approximately 4.1 times, presence many different factors significantly affect design features sprayers. In particular, this may be related consumer requests. Theoretical empirical series mass are presented. The studied indicator equal 35.1%. With confidence probability 0.95, calculated weight 2.69 15.35 tons.
