“…Lateral stability was ensured with the tractor mulcher mounted on a hydraulic arm connected to the tractor using a 3 point hitch. The results of the tractor stability analysis were found with respect to the torque forces caused by the mulcher support arms weight and other present forces during its work operation (Bartoň et al, 2017)…”

Soil organic carbon was monitored from 2013 to 2016 in two fishpond dikes of different variants of grass species composition: variant 1 -grass mix for extensively dry conditions, variant 2 -heavy duty grass mix, variant 3 -grass mix for intensively moist areas. The monitored grass vegetation was mowed twice a year. In terms of texture, the dike of Pond Rohatec is composed of sandy soil, while the dike of Pond Podhorský consists of loam to clay-loam soils. As to soil structure, the most suitable variant on the Rohatec dike proved to be the mix for extensive drought, while the best variant on the Podhorský dike was the mix for heavy duty areas. The highest organic carbon (C org ) content has been found in the above-mentioned variants. It is obvious that C org content and suitable grass mixture thus positively affect soil structure. The dike of Pond Rohatec showed higher humus quality than Pond Podhorský, which reflected the overall more favourable composition of the dike of Pond Rohatec. These results are important as to the protection of dikes against erosion effects and for faster growth of grass mixtures.

The paper deals with a construction design and structural analysis of the rack system which will be used for storage of steel tubes of pressure pipeline for fodder mixtures transportation in agricultural company. Structure of the designed equipment is made by the welding of steel parts and consists of the main framework and four pull-out racks on both sides. Racks move by means of human power through a rotating crank. Every individual pull-out racks is able to carries pipes of various dimensions, both length and diameter with total weight up to 3 tons with respect to customer requests. Since it is a prototype's structure, we have designed main dimensions of it, material and technology for production and performed also structural analyses as the integral part of every engineering design. Structural analyses were conducted by means of numeric procedure known as finite element method. With respect to the used steel profiles shell elements were used for FE model. Analyses were performed for maximal loading cases in order to identify the level of safety in the most exposed locations of the structure.
