Technicko ekonomické hodnocení vybrané traktorové soupravy na zpracování půdy v podmínkách AGRO Záblatí

This master´s thesis is divided into two parts. The first one is a theoretical part and deals with the current situation in the tractor´s construction, particularly motor systems for reducing the emission of harmful substances in exhaust gases, tractor transmissions and electro-hydraulic system. In the second practical part the measuring of economic parameters of the tractor rigs during plowing was conducted and processed. The measured parameters were fuel consumption, engine speed, tillage depth, width, time and total time for rotation. Theme assured parameters which calculated the operational and efficient fuel consumption and the performance kit. These values were processed in graphical and tabular form. They were detected by measuring the parameters of the efficiency and diesel consumption during operation for the tractor rigs John Deere 8220 equipped with a rotary plow KVERNELAND PN 100 with seven tines. The measurement was in the economic engine speed (1600 to 1800 rpm) and (1800 to 2100 rpm) considering a full dose of fuel
