Design of a stubble cultivators for aggregation with a tractor 75k
Krutský, Lukáš ; Fajkus, Pavel (referee) ; Kašpárek, Jaroslav (advisor)
This bachelor's thesis deals with the design of a fully mounted cultivator in a three-point tractor hitch, cat. 2N/2. A short search of similar equipment and tractors of the corresponding power range was performed. The concept is designed and based on analytical calculations of dimensional and functional properties. Strength calculations are performed according to the standard, critical points of the equipment are checked. The work contains pictures of 3D models and drawing documentation.

Porovnání exploatačních parametrů kotoučových a radličkových podmítačů ve vybraném zemědělském podniku
PROCHÁZKA, Miroslav
The aim of this diploma thesis is to approach the possibilities of processing agricultural land with a suitable type of cultivator. The professional part of the work captures different types of tillage and introduces the types of cultivators. The practical part of the work is devoted to measuring the area performance and fuel consumption in soil preparation with a coulter and disc cultivator in the specific conditions of an agricultural enterprise in the Czech Republic. Evaluates the measurement results and presents conclusions for practice.

Porovnání orebného a bezorebného zpracování půdy
BARTOŠ, Jiří
The bachelor's thesis deals with the most commonly used tillage technologies today and the impact on soil compaction. It also focuses on measures against unwanted compaction and its subsequent removal. Describes basic work operations such as plowing and loosening the soil. The bachelor's thesis describes the principle on which plowing works, basic types and distribution of plows, possible equipment of plows and according to which plowing can be divided. Furthermore, the methods of plowing, on different types of land, under conditions. Last but not least, the advantages and disadvantages of the most common tillage are listed here. Furthermore, the loosening technology, the machines with which the soil can be worked and the advantages and disadvantages of the tillage technology without plowing bring here. The experiment performed for the purpose of the bachelor's thesis is focused on the comparison of plowing and no-till technology of soil processing from an economic point of view and within the possibilities of verifying the impact on soil condition, stand condition, harvest and environment.

Comparison of plowing and no-till tillage
DOLEJŠÍ, Přemysl
This final thesis deals with the comparison of plowing and non-plowing soil tillage. It is divided into theoretical and practical part. The theoretical part describes soil properties and importance of soil cultivation. Following is a presentation and description of selected technologies of soil cultivation. The practical part presents the measurement results. It was investigated whether this or that technology was more cost-effective and how different processing would affect soil compaction. The results are presented for the sake of clarity through tables and graphs.

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.
