A broadcast spreader is a gardening tool used to evenly distribute seeds, fertilizers, or other granular materials over a large area. It typically consists of a hopper that holds the material and a rotating disc that flings it outward as the user walks. This allows for efficient coverage of lawns, gardens, and agricultural fields. These spreaders come in various sizes, from small hand-held models to larger tow-behind versions that can be attached to a lawn tractor or ATV. Proper calibration is essential to ensure the right amount of material is applied, promoting healthy growth and preventing waste.
