Salt spreaders are machines used to distribute salt or other de-icing materials on roads, driveways, and sidewalks during winter weather. They help prevent ice formation and improve traction for vehicles and pedestrians. Salt spreaders can be towed behind vehicles or operated by hand, depending on the size of the area that needs treatment. These devices come in various types, including broadcast spreaders, which fling salt over a wide area, and drop spreaders, which release salt directly below the machine. Using a salt spreader efficiently can help keep surfaces safe and reduce the risk of accidents during icy conditions.
