Design of a stubble cultivators for aggregation with a tractor 75k
Krutský, Lukáš ; Fajkus, Pavel (referee) ; Kašpárek, Jaroslav (advisor)
This bachelor's thesis deals with the design of a fully mounted cultivator in a three-point tractor hitch, cat. 2N/2. A short search of similar equipment and tractors of the corresponding power range was performed. The concept is designed and based on analytical calculations of dimensional and functional properties. Strength calculations are performed according to the standard, critical points of the equipment are checked. The work contains pictures of 3D models and drawing documentation.

High pressure hydraulics in agricultural machinery
Pavlík, Václav ; Kárník, Jan (referee) ; Soukup, Lubomír (advisor)
This bachelor thesis provides an overview of the most used ways of converting kinetic energy into pressure energy and the other way around by using hydrostatic converters. It is focused on the issue of high-pressure hydraulic mechanisms in agricultural machinery. In the next section I focused on getting an overview of the function of sophisticated hydraulic systems in current tractors and calculation of heat losses of lifting weight by front three-point hitch. For solving was used Bernoulli equation for real flow in pipes.
