Ergonomie kabiny sklizňových strojů
Solař, Josef
This bachelor thesis focuses on evaluating the approach of harvester manufacturers to control ergonomics. The aim of the bachelor thesis was to compare five controls between the four best selling harvester manufacturers on the Czech market. The comparison was made by developing a methodology based on the parameters used from the selected literature and was tailored to the harvester control with a division according to the consideration of motor skills, field of vision, recognition, display and the number of steps required to activate. A description of harvesting threshers and ergonomics in general and in the context of harvesting threshers is not missing part of the work. The development trend of harvester control is also described at the end.

Vliv strojů a strojních souprav v rostlinné výrobě na nežádoucí zhutnění půdy
Svoboda, Martin
The dissertation deals with influence of machines and machine sets on unwanted soil compaction in agriculture production. In the literary part, the thesis deals with soil problems, current state of agricultural technology and its decisive parts in relation to the soil, physical properties of soil and penetrometry. The goal of the dissertation is to evaluate interactions of impact of tractor or combine harvester crossings on soil compaction. The effect of tractor and combine harvester crossings was measured by the degree of soil compaction by penetrometer resistance of the soil. At the same time, the physical properties of the soil were monitored by using the method of Kopecký roller analysis. In the field-laboratory measurement of soil compaction was used tractor with different loads, different tire pressure and dual tyres on rear axle. The influence of the first crossing, repeated crossings and no crossing was assessed. The results of the measurements confirm suitability of using modern tires which are able to work with lower inflation pressures, have a flexible sidewall and can be mount as dual or triple tyres.
