Analysis of Zetor tractor output parameters with different gearbox design
Orság, Josef ; Škopán, Miroslav (referee) ; Bauer, František (advisor)
This thesis deals with energetical and efficiency comparison of two tractor transmission types, used by the Zetor company. The description of transmission construction types of various tractor producers is given, with focus on Zetor tractors transmission construction. The laboratory methodology and operating tractor and tractor sets measurement is described. The individual results are introduced in tables and graphs and subsequently evaluated.

Analysis of technical-economic parameters of the tractor kits in transport
Krátký, Martin ; Slimařík, Dušan (referee) ; Bauer, František (advisor)
This thesis deals with the use of the tractor in agricultural transport. The first part describes the current status in construction of tractor engines, transmissions and chassis that are used in tractors suitable for transport. The theoretical section includes an overview of the legislative requirements that must be followed for the tractor kits in transport on the road. The main objective of this thesis was to evaluate a measuring of fuel consumption and efficiency of the tractor JCB Fastrac 185-65 with two flatbed trailers. For this purpose was created the methodics off terrain measurement, which were carried out for different operation modes of the engine. The results were tabular and graphical processing including determining the accuracy of the method by calculating the relative error of measurement. For comparison a theoretical calculation of the consumed fuel was made. The aim of the measurements was to demonstrate fuel-saving during operation engine in the economic field and get an overview about fuel consumption and efficiency kits.

Technická exploatace a ekonomická efektivita traktorových souprav v dopravě
Svoboda, Michal
The thesis gives the reader a comprehensive overview of the construction of agricultural tractors with regard to their use in transport and their economic evaluation. The theoretical part deals with the construction of modern tractor and homologation for the road traffic. The conclusion of this thesis is dedicated to the practical measurement of the tractor set in transport with respect to the maximum speed of 50 km.h-1, 40 km.h-1 and 40 km.h-1 at the reduced engine speed.

Dopravní a manipulační prostředky při zakládání zeleně
Dušková, Barbora
The bachelor work deals with the characteristics of individual groups of transport and handling equipment, the analysis of the transport cycle and the selection of appropriate transport and handling equipment in accordance with the conditions of their use. There are characterized nine categories of transport and handling equipment, and four representatives -- a multicar, a small tractor, a tractor and a truck -- were chosen for modelling transport efficiency calculations. Transport performance was found not only for different types of vehicles, but also at different distances and under different conditions. The results of this work can be used in planning and calculation of costs.

Perform analysis of the technological services in medium-sized enterprises of agricultural primary production and its design optimization.
BRYCH, Jiří
Abstrakt This paper solves the analysis of the technological transportation in a medium-sized enterprise, with its subsequent design optimization. The aim is to analyze existing traffic and then propose appropriate measures to streamline the labor-saving technological services in the selected primary agricultural enterprise with selected comparative parameters. This paper will attempt to answer questions. How to reduce transport costs in agriculture? What and how to properly transport the material in agriculture? The theoretical part contains the characteristics of transportation technology on the farm, focusing on the removal forage. Describes suitable transport means for removing material from the harvester and the chosen parameters for the comparative analysis of the technological transportation. The basis for the practical part of the surveillance and measurement of traffic operations on the farm and ZEMPO-VOS Strunkovice nad Blanicí. And based on selected indicators were calculated values, which were compared with the technical and technological norms for agricultural production of the Czech Republic. The last part of the thesis deals with the optimization of the removal of maize silage for cattle forage harvesters from the silage trough. Are described herein suitable means of transport options within the company, including calculations and comparison of selected indicators of the actual removal of silage maize . The conclusion of this study imply the need to increase the removal of corn silage size transport´s resources, compared to current technology.
