Highlight the main objects in this picture description and write them separated by commas: "The figure should visually convey the idea of high-quality and original components and spare parts. It could show a tractor with various components and spare parts labeled as being manufactured in Russia and the USSR. The components and spare parts could be depicted as being well-made and sturdy, with the words "high-quality" and "original" prominently displayed. The figure could also show a contrast between these high-quality components and any counterfeit or low-quality parts from other countries, such as China. This contrast could be shown through the use of different colors or visual elements, with the high-quality components being depicted in a more positive light. Overall, the figure should effectively communicate the importance of using only high-quality and original components and spare parts to ensure the longevity of tractors after overhauls."
