Working body of the disk stubble plough
Smola, Tomáš ; Zimmerman, Martin (referee) ; Brandejs, Jan (advisor)
The aim of this bachelor thesis is to map a knowledge survey of present state in the area of disk plough-harrows and its working organs’ construction. In the first part is briefly described history of agriculture, development and possible structural design of disk plough-harrows. Further it focuses on the best variant choice and working organs’ construction. In conclusion follows the evaluation of established knowledge.

Analysis of the structural joints of the disc tiller
Smola, Tomáš ; Dzimko, Marián (referee) ; Brandejs, Jan (advisor)
The aim of this diploma thesis is to analyse loading forces which impact on the frame of the disk plough-harrow during the real operation, suggestion and assembling of the measuring system for measuring of real loading. On the basis of this measuring to accomplish structural deformational tensor analysis of the frames load-bearing’s machine. In the introduction is shortly described using of the disk plough-harrow in modern agriculture. The diploma thesis is divided into two parts. The first part is devoted to the suggestion of the measuring system and loading measuring under real working conditions. The second part is focused on deformational tensor analysis of the frames load-bearing’s machine through the method of final elements. In conclusion it follows the evaluation of gained pieces of knowledge.

Porovnání diskového a radličkového podmítače
NOVOTNÝ, Filip
The diploma thesis deals with an issue of stubble plough under and a comparison of dise and skive stubble ploughs. The introductory theoretical part sums up the basic information about a soil and its treatment, information about agricultural machinery and concrete sorting stubble ploughs according to their working organs. A short history of Lemken company follows. The second part of the thesis compares the disc and the skive stubble ploughs in conditions of the agricultural company Zas Dražice Plc. Following gauges were examined during the field tests: cloddishness in cultivated part of the soil, defray postharvest rests, gas consumption or investment and operating costs.

Comparison turntable and stubble plough in light of qualities effected stubble ploughed under and gas consumption.
RŮŽIČKA, Jiří
This thesis concentrates in problematics of stubble ploughed under and comparission disk and skive stubble plough. First part contains the summary of theoretical knowledge of soil and its elaboration, as well as the knowledge of farm machinery and specific division of stubble ploughs by its working organs. Follows by the summary of the most used and sold stubble ploughs in Czech Republic within its detailed description. Second part constitutes confrontation of skive stubble plough and turntable stubble plough in conditions of company Agro Malinová. In the field experiment have been discovered these measurements: defray postharvest rests, worked profile, cloddishness, penetrometer resistency, gas consumption and soil humidity.

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.
