Vliv seřízení tříbodového závěsu traktoru na výstupní parametry orebních souprav
 Kratochvíl, Ivo
The aim of the thesis "Influence of adjustment of three-point tractor hitch on output parameters of tractor sets" was to elaborate the current state of the tractor construction and to find out above all, the influence of adjustment of the three-point hitch of the tractor and setting of the working machine on output parameters of tractor sets. Part of the work was the experimental measurement of a total of three tractor sets with full mounted depth cultivator, full mounted plow and semi-mounted plow. For the first tractor set, the effect of thrust and pressure in the upper pull rod of three-point tractor hitch on the output parameters of the tractor set with depth cultivator was determined. For the second plow tractor set, the influence of the length of the upper pull rod of three-point tractor hitch on the parameters of the plow tractor set was determined. In the third plow tractor set with a semi-mounted plow equipped with a traction cylinder, the influence of the pressure in the traction cylinder on the output parameters of the plow tractor set was determined. From all three measurements, the results have been achieved that when the three-point tractor hitch is correctly adjusted, it reduces slippage, increases surface performance and decreases fuel consumption.

Hloubkové kypřiče, jejich využití a význam při pěstování obilovin a řepky ozimé
 NOVOTNÝ, Jiří
Various technologies can be used to process soil. In ZOD "Blata", plow technology is utilized by the plow and the technology is grooved using a deep cultivator. For each technology, a time frame was processed and their performance calculated. In addition, both soil cultivation technologies were compared in winter wheat and winter rape production between 2016 and 2017.
