Influence of three-point hitch parameters on traction properties of tractors
Voburka, Tomáš ; Škopán, Miroslav (referee) ; Bauer, František (advisor)
The diploma thesis is focused on the development of a mathematical model of the tractor-tool set in the MSC Adams program enabling analysis of the influence of the position of the upper linkage of the three-point hitch on the load of the driving wheels during the system operation. The measured force effects are analysed with focus on the adhesion load of the drive wheels and the traction properties of the tractor. Based on the calculations made, it determines the optimal setting of the upper link of the hitch for the connected tool.

Concept of the rotary harrow
Moštěk, Michal ; Fajkus, Pavel (referee) ; Kašpárek, Jaroslav (advisor)
The bachelor's thesis deals with the design of a rotary harrow. In the beginning of the thesis, a short research is written regarding soil cultivation. Rotary harrows and tractors in the corresponding power series are listed in the next chapter. In the next part of the work, individual components are described and their selection is justified. The construction of individual components is described in a separate chapter. The rotary gate is designed with a three-point hinge cat. 2N/2. In the last part of the work, the strength calculation of the gears, the basic durability of the rotor bearings and the inspection of the shaft of the bearings is carried out. Calculations are made according to standards. The work includes drawing documentation and images of the 3D model.
