What is the primary use of a rotary spreader?

The primary use of a rotary spreader is to apply granular products to turfgrass. These spreaders are designed to distribute materials such as fertilizers, herbicides, and insecticides evenly over a large area. When using a rotary spreader, the granular material is dropped onto rotating blades, which cast it outwards in a wide, fan-like pattern. This is particularly effective for treating lawns, gardens, and landscaped areas, ensuring that the product is applied uniformly, which is crucial for achieving the desired results in turf maintenance.

While rotary spreaders could potentially be used for broadcasting seeds, their main function is more commonly associated with granular product application. They are not designed for liquid applications, hence do not fulfill options like applying liquid pesticides or watering ornamental plants.
