Analysis of technical-economic parameters of the tractor kits in transport
 Krátký, Martin ; Slimařík, Dušan (referee) ; Bauer, František (advisor)
This thesis deals with the use of the tractor in agricultural transport. The first part describes the current status in construction of tractor engines, transmissions and chassis that are used in tractors suitable for transport. The theoretical section includes an overview of the legislative requirements that must be followed for the tractor kits in transport on the road. The main objective of this thesis was to evaluate a measuring of fuel consumption and efficiency of the tractor JCB Fastrac 185-65 with two flatbed trailers. For this purpose was created the methodics off terrain measurement, which were carried out for different operation modes of the engine. The results were tabular and graphical processing including determining the accuracy of the method by calculating the relative error of measurement. For comparison a theoretical calculation of the consumed fuel was made. The aim of the measurements was to demonstrate fuel-saving during operation engine in the economic field and get an overview about fuel consumption and efficiency kits.

Spread of sound pressure on a tractor JCB Fastrac
 RYŠAVÝ, Tomáš
The aim of the bachelor thesis is to determine the way how noise spreads from a tractor, noisiness at operator during different operations and then to enumerate equivalent sound-pressure level. The tractor JCB Fastrac 2170 was used for measurement. The first part of the thesis introduces the noise issue, noise of tractors, and then the development of Fastrac tractors. The next part of the thesis shows measured values of the observed tractor in graphs. Then equivalent sound-pressure levels are enumerated from those measured values. In conclusion, these values are evaluated and compared.
