Identification and evaluation of customer preferences for selected product
Tůma, Milan ; Hurta, Jakub (referee) ; Chlebovský, Vít (advisor)
Finding customer preferences when deciding about buying a tractor in the 201-300 horsepower category. Attributes will be gained through questionnaire survey, and will be used in the QFD method, where there will also be comparison of major competitors in a given market segment. The evaluation of tractors will also include the voice of the customer, gained from KANO model. KANO model will be second survey that will be used in this thesis. The conclusion is to build an ideal tractor structure that matches the customer's wishes.

Testing of piston combustion engines
Humpolíček, František ; Kloss, Ondřej (referee) ; Kaplan, Zdeněk (advisor)
The aim of this thesis is to compile knowledge and provide a comprehensive overview of the testing of piston combustion engines, dynamometers and types of testing for engines designed for agricultural machinery. Types of various tests are described, dynamometers are categorized and the characteristics of individual components are studied. Different types of tests are also categorized and their principles summarized. Based upon these findings, the most suitable configurations are determined for a borrowed dynamometer to measure agricultural machinery. The borrowed dynamometer was used to conduct practical measurements of the external speed characteristics of combustion engines in agricultural machinery. It was experimentally determined that the duration of measurement is limited by the reduced efficiency of eddy current brakes due to increasing rotor temperature.
