The diploma thesis on the theme Analysis of the Output Parameters of Tractors Kit for Soil Preparation contains in theoretical part actual survey of most important parts of the tractors. The diploma thesis further includes description of tractors CLAAS ARION 640 with mechanical speed gearbox HEXASHIFT and continuous hydrostatic gearbox CMATIC and description of plow PÖTTINGER servo 45S NP, which were all together elements of the practical part. The field measurement took place in Jiřice at Miroslav on Znojemsko in august 2016. This measurement is processed in the practical part, which focuses on comparing tensile characteristics of both gearboxes and determining their influence on the tensile properties of the tractor. Results were tabular and graphically elaborated and the analysis of measured values was performed.

The master thesis describes the methodology of laboratory and field measurements of tractors and tractor kits. It also contains graphical and tabular processing of measurement data and subsequent evaluation of the results obtained. It deals with the influence of power in the upper rod of three point hinge on wheel slip, work efficiency and fuel consumption.

This diploma thesis “Analysis of powertrain impact on pull power capacity of a tractor” is focused on evaluation of measured data gained from performance testing of tractors Claas Arion 640 for two different types of transmission. There are also discussed the measuring methods and there is detailed described the function of measured transmissions.
