Hodnocení technicko-ekonomických parametrů traktorových souprav na zpracování půdy.
Janů, Radek
The Master’s thesis presents contemporary methods of soil cultivation. Emphasis is placed both on conventional soil tillage and minimum tillage practices. Different methods of tillage are systematically classified and characterized, and machines for individual methods of soil cultivation are introduced. The second part contains the methodology of field measurement of Fendt 924 Vario, John Deere 6215R Plus, and Pöttinger Servo Plus 6.50 plow, Pöttinger Synkro 3020 plow, Pöttinger Synkro 6020 NOVA, and Pöttinger Terradisc 6001 T. It follows from the measured values that higher performance was achieved with the plow stubble cultivator, while lower fuel consumption for the cultivation of 1 ha of land was achieved during plowing.

Analýza výstupních parametrů traktorových souprav na zpracování půdy
Řihák, Pavel
The diploma thesis is called Analysis of the output parameters of tractor’s sets to processing land. It is focused on overview of technologies in processing land. The first part is focused on the main machines and their parts used in the classical convention and the minimization farming of land. Each chapter is supplemented for graphic overview suitable illustrations of machines and tools. The second part of this thesis includes methodology of terrain measurement tractor’s set the Case IH Puma 230 CVX and cultivator the Lemken Karat 9 in processing land focusing on the influence of output values at different setting parameters. At tractor’s set were followed output values such as fuel consumption, slip of wheels, revolutions engine, working time, rotation time, speed. The efficient and operational performance and fuel consumption of the set were calculated from ascertained values. This chapter describes in detail hydrostatic gearbox of CVX tractor Case IH Puma. The conclusion of this work is the evaluation full issue.

Využití hloubkového kypřiče při pěstování obilovin a řepky olejné v podniku Zemědělské služby Dynín, a.s.
KUBEŠ, Jan
This diploma thesis deals with deep cultivators which are used in companies of agricultural production. Theoretical part is focused on the history of soil proccessing, soil treatement and loosening machines which are being used today. That includes disc cultivators, tine cultivators, chisel cultivators, rod cultivators and machines with driven work gears. Practical part of theses includes comparison of chisel cultivator and plough doing tillage. The quality of keeping the depth invariable is being evaluated, as well as time-consuming nature, consumption of fuel and drain on resources.

Porovnání orebné a bezorebné technologie zpracování půdy z hlediska jejího zhutnění
MACH, Václav
The bachelor thesis focuses on technologies of soil cultivation which are nowadays most frequently used in our country and what is their influence in soil compaction. It describes reasons of the origins of soil compaction, impacts of the compaction and the effect of compaction on soil as a unit. It also focuses on procedure? against unwanted compaction or its following elimination. Subsequently, the thesis describes basic work operations which are plowing and aeration. There are details of the principle how the plough works, basic types of ploughs and the way how we can divide plowing. There are also methods of plowing which are applied in different conditions on land. Last but not least, the thesis points out advantages and disadvantages of this most common soil cultivation. It deals with technologies of aeration as well as it deals with machines which are able to cultivate soil or with technologies of soil cultivation and their advantages and disadvantages in work without a plough. The field experiment which has been done for drawing up of this bachelor thesis focuses on comparison of ploughing and non-ploughing technologies of soil cultivation in a way of its compaction. There is evaluation of the penetrometric resistance, of the achieved depth in measurement and the soil moisture. These values have been measured on a field which was divided according to the technology of soil cultivation. The first part was done conventionally with the plough and in the second part the plough was replaced with the aeration. The results of the measurement were then compared with the whole soil profile of the measurement, then in the depth of 20 cm and finally with rest the horizon of measurement. Values and comparisons of the individual measurements are for better illustration noted in tables and marked on graph.

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.

Možnosti snižování nákladů u traktorových souprav na zpracování půdy
Fajmon, Jiří
The thesis on the theme-Possibilities of reduction costs by tractors kit for treatment of soil-is giving us in the theoretic part basic information about construction of nowadays tractors, possibilities its traction and effectiveness of use. It deals with economy of treatment of soil primarily with energy demands and effectiveness tillage. In the practical part of this thesis is processed field measurements, which was made for purpose to evaluate usage of traction hydraulic cylinder plough. It was investigated how the features of traction cylinder are influencing fuel consumption, traction of wheel and efficiency of tractors kit.
