Analysis of energy and performance parameters of tractor sets for tillage
 Masnica, Daniel ; Porteš, Petr (referee) ; Bauer, František (advisor)
This diploma thesis analyzes the influences of individual components and settings on the performance and energy parameters of tractor sets. The theoretical part of the thesis focuses on tractor construction and describes some electronic systems used in modern tractors. It also describes the methodology of field measurements, measuring techniques, and machinery used for the measurements. The practical part of the thesis deals with field measurements of a tractor set with a combined cultivator, a plow, and traction tests of the tractor. From the measured data, various performance and energy parameters are calculated. The results are analyzed, and a discussion is provided.

Vliv použitého nářadí na kvalitu zpracování půdy
 PIŠL, Stanislav
For the evaluation of this diploma thesis I have chosen four different processing machines with various working organs. There were reversible plow Lemken Opal 90, plate cultivator Horsch Joker 8 RT, blade cultivator Farmet Duolent DX 300 N and combined cultivator Väderstad TopDown TD 500. Raitings were carried out on lands with very similar features to get the most advantageous possible comparison. The thesis contains characteristics of the companies and technical data of compared machines, where the machines differences are obvious, because each machine is designed and assembled for different purpose of soil processing. The fact is that each machine excelled in different type of measuring from the qualitative indicators' point of view. The best cultivation of plant residues came from the plow Lemken Opal 90. On the other hand, Väderstad TopDown TD 500 had the most decaying effect on post-harvest residues.
