Posouzení různých způsobů soustřeďování dříví v podmínkách Malých Karpat
Murín, Ondrej
The key topic of this bachelor thesis is the evaluation of various mechanization equipment within the mechanized method of skidding in the Little Carpathians and a discussion of their economic and technical indicators, and ergonomic demands of their operation. The theoretical part of the work deals with the issue of damage to the forest ecosystem by mechanization equipment, the energy intensity of work for operating workers, and the characteristics of the used methods of skidding. The practical part of the work contains the results of measuring the quantities contained in the above issues in addition to other important indicators, such as time observation and economic inputs and outputs. The measured values are evaluated and compared with each other according to the set criteria. In conclusion, the author assesses the possibilities of using the mentioned mechanization equipment in the conditions of the Little Carpathians.

Mechanizace sklizně vinné révy
Zborovský, Miroslav
The bachelor thesis deals with the mechanization of grape harvest in viticulture. It describes the development of mechanical grape harvest and focuses on specific types of machines currently available on the market as well as their historical background. The agrotechnical requirements necessary for establishing a vineyard with a vision for future mechanized operations are also evaluated. Using data from professional literature and technical specifications, relevant parameters that grape harvesting machines must meet are determined, followed by an assessment of two machines from the brands PELLENC and NEW HOLLAND.
