The image displays a component of a potato side-discharge harvester, specifically showcasing a limiting width disc. This component consists of a circular blade, a mounting frame, compression springs, and an adjustment mechanism. The non-powered circular disc blade is primarily used for cutting the surface along the ridge, including weeds and other unwanted vegetation. The design allows for precise control of the cutting width, ensuring efficient and clean harvesting by maintaining the field's integrity and reducing crop loss.

The image displays the depth control mechanism of a potato side-discharge harvesting machine, integral for precise underground work. This system comprises contour-following depth wheels, support brackets, and an adjustment mechanism. The depth wheels are designed to regulate and maintain the digging depth of the shovels, ensuring that the potatoes are loosened from the soil efficiently, which facilitates subsequent separation of the tubers from the earth. Presented in vivid red and green, the apparatus combines functionality with robust design, ensuring that the harvesting process is as effective and soil-friendly as possible. This depth control mechanism is essential for maintaining consistent excavation depths, optimizing harvest quality, and minimizing crop damage.
