Stone pickers are used in farming and landscaping, where stones need to be removed from the soil and ground surface to prevent damage to other farm machinery (such as hay balers, combines, and mowers), improve the soil for crop production. A stone burier is a piece of agricultural equipment designed to till and level soil while burying stones, debris, and other unwanted materials beneath the surface. It's used in various applications, including agriculture, vegetable gardening, fruit-growing, and landscaping. Essentially, it helps create a smooth, stone-free surface for planting and other activities.
