Abstract Tractors are used for various types of field work, as well transport on public roads, in difficult and changing environmental conditions. The main goal the study was to analyze changes trace elements engine oil during works. For this purpose, oils from two tractors were selected study. These coupled with: a cultivator, reversible plow, tillage-sowing unit, trailer. samples taken at beg...

Clostridium pseudotetanicum was isolated along with Serratia marcescens, Proteus mirabilis, and Staphylococcus epidermidis from a patient suffering from gas gangrene who had been injured in the right leg by a power cultivator. Experimental infection of the hind leg of mice with C. pseudotetanicum and the three kinds of aerobic bacteria did not produce any different macroscopic finding in the in...

As the working efficiency and life span of shovel plate a roadheader directly influence its performance, optimization shovel-plate parameters is crucial. For optimizing parameters, variations in loading capacity grubbing force with respect to are determined this study. Moreover, ideal point method gray weight proposed for multiobjective optimization. The weights resistance by investigating exis...

Alloyed carbon steels used in ground engaging tools (GETs), such as shovel-teeth, can withstand high working loads, but their wear resistance is inadequate for abrasive operations the mining industry. Different approaches to engineer protective surfaces on GETs improving have been developed over years, effectiveness of applied layer has limited by maximum thickness that be realized reliably. Co...
