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.

This master´s thesis is divided into two parts. The first one is a theoretical part and deals with the current situation in the tractor´s construction, particularly motor systems for reducing the emission of harmful substances in exhaust gases, tractor transmissions and electro-hydraulic system. In the second practical part the measuring of economic parameters of the tractor rigs during plowing was conducted and processed. The measured parameters were fuel consumption, engine speed, tillage depth, width, time and total time for rotation. Theme assured parameters which calculated the operational and efficient fuel consumption and the performance kit. These values were processed in graphical and tabular form. They were detected by measuring the parameters of the efficiency and diesel consumption during operation for the tractor rigs John Deere 8220 equipped with a rotary plow KVERNELAND PN 100 with seven tines. The measurement was in the economic engine speed (1600 to 1800 rpm) and (1800 to 2100 rpm) considering a full dose of fuel.

Epa kulturen börjar idag nå ut till den stora massan genom Epa-dunk musiken. Själva fortskaffningsmedlet är dock fortfarande relativt otillgängligt för många. Mycket av möjligheterna att äga och kunna reparera en epa traktor kommer genom ungdomars föräldrar och deras ekonomiska möjligheter. De flesta av ungdomarna som kör epa bor i villa och har föräldrar som till viss del har ett motorintresse och på så vis kan hjälpa till och kanske till och med undervisa sina barn i mekaniken. Kånkels hus hade kunnat möjliggöra detta för många fler vilkas föräldrar kanske inte bor i villa med garage eller inte har intresse av motorfordon. Kulturen runt motorfordon har länge bland ungdomar varit färgad av den tätt kopplade musiken. Artister som Eddie Meduza, Fröken Susk och Onkel Kånkel har en anda av ungdomlig obstinatism och punkighet vilken har fått leda utformningen av Kånkels hus. Post-Modernismens lek och omkastning av det klassiska är kanske det närmaste punk och könsrock vi har inom arkitektur. Därför föll valet att studera och praktisera en del av Post-Modernismen sig naturligt i projektet. / Epa culture is beginning to reach the masses through Epa-dunk music. However, the means of transportation themselves are still relatively inaccessible to the many. Much of the opportunity to own and be able to repair an epa tractor comes through the parents of young people, and their financial capabilities. Most of the young people who drive epa live in villas and have parents who to some extent have an interest in motoring and thus can help and maybe even teach their children mechanics. Kånkel's house could make this possible for many more whose parents may not live in a villa with a garage or have no interest in motor vehicles. The culture around motor vehicles has long been colored by the closely connected music among young people. Artists such as Eddie Meduza, Fröken Susk and Onkel Kånkel have a spirit of youthful obstinacy and punkness which has led the design of Kånkel's house. Post-Modernism's play with the classical elements of architecture is perhaps the closest thing to punk and gender rock we have in architecture. Therefore, the choice to study and practice a part of Post-Modernism fell naturally into the project.

The main subject of this master‘s thesis is an innovative approach to design of an ag- ricultural tractor with technical, esthetic, ergonomic and economic demands. The aim is to create a distinctive design and shape of tractor unbound from conventional solutions. The concept takes account of the farm–machine relationship, the alterna- tive powertrain, and friendliness to the environment.

The thesis deals with the current state of tractor gearboxes. The first part introduces the history of tractors. Furthermore, the concept of powertrain and the distribution of tractor transmissions are explained, followed by a structure description of each of them. Beyond that, the principle of the gearbox function is described as well as its use and for better understanding most of the explanations are complemented with images. The next part deals with comparing the different power classes of tractors in terms of transmissions, speeds and specific fuel consumption. All aspects and results are summarized in conclusion.

Traction efficiency of tractors barely reaches 50 % in field operations. On the other hand, modern trends in agriculture show growth of the global tractor markets and at the same time increased demands for greenhouse gas emission reduction as well as energy efficiency due to increasing fuel costs. Engine power of farm tractors is growing at 1.8 kW per year reaching today about 500 kW for the highest traction class machines. The problem of effective use of energy has become crucial. Existing slip control approaches for tractors do not fulfil this requirement due to fixed reference set-point. The present work suggests an optimal control scheme based on set-point optimization and on assessment of soil conditions, namely, wheel-ground parameter identification using fuzzy-logic-assisted adaptive unscented Kalman filter.

The present master thesis deals with the topic of load applied to driving wheels of tractors and its impact on output parameters of tilling systems. Introduction describes the advantages and disadvantages of tillage. It briefly presents its history, evolution and possible improvements of its parameters by correct plough and three-point linkage system of tractor settings. The following part explains the impact of load distribution between tractor driving wheels on its thrust properties. Some possibilities of improving load distribution between driving wheels are also specified and described here. Special attention was dedicated to improvement of load distribution by transferring part of the plough weight to the tractor. The practical part of the thesis explored the impact of force in upper linkage of three-point linkage system of tractor on the force transfer and subsequently on the output parameters of tilling systems. Two measurements were processed in the present master thesis, one focusing on the total additional loading or tractor rear axle and one focused on balancing the load difference between the right-hand side and left-hand side wheel of rear axle. The measured values were processed in tabular form and further evaluated by regression analysis. Conclusion was formulated based on the identified results.

Diploma thesis is dealing with proposal of suitable farm implements and technologies for tractors of over 250 kW according to chosen methodologies at agricultural business AGRO Slatiny a.s. The introduction specifies a brief characteristic of selected agricultural business which is followed by a description of soil processing methods and comparison of wheeled and crawler tractors. In the next section there is a characteristic of 3 powerful tractors of over 250 kW and implements which are used by those tractors for soil preparation. Furthermore there is a specification of main objective and applied methods. The main goal was calculation of original implement's parameters in regards to work efficiency and economic evaluation. In case of unsatisfactory results the objective is to propose new implements in order to work more efficiently and have better economic results.

In forestry are used heavy wheeled machines which create noticeable pressure on the soil by landing gear. Traversing machines cause damaging roots, root swellings and especially soil compaction. This thesis deals with the assessment and comparison of factors affecting the immediate pressures in the soil profile caused by crossing forwarders. Two machines are considered, the first one with load capacity 5t and the second one with load capacity 12t. The technical features of the machine, tire width, tire inflation rate and technological influences, putting brushwood on the path of crossing forwarder were assessed. The results indicate that the use of logging residues on the path of forwarder effectively reduces the immediate pressures in the soil.

The main aim of this diploma thesis is to determine the radius of rotation of selected tractors (Zetor Forterra 140 HSX, Zetor Proxima 120 Power and Zetor 7745 Turbo) on three different types of surfaces using different speeds. The literary part deals briefly with the importance and historical development of tractors, the basic knowledge of traction theory, the problems of forces acting on the rolling wheel, and last but not least the construction of the tractor parts. The practical part is mainly focused on determining the radii of rotation of individual tractors on three specified types of surfaces using the three given speeds. The discussion is mainly focused on comparing the radii of rotation meeting ČSN 30 0552 with the radii given by the tractor manufacturer.
