Moreover, the farmland often contains stones of various sizes, which can cause serious wear and tear to farm tools, increasing maintenance costs and replacement frequency, and hindering the smooth progress of farm operations. For example, during plowing, stones can cause damage to plows; during sowing, stones can affect the normal operation of the sowing machine, causing inconsistent sowing depth.
