The rotary spreader is recognized for its ability to apply granules over a wide area, typically producing a swath of 6 to 12 feet. This is achieved through a mechanism that uses a rotating disc or plate to distribute the granules in a uniform pattern as the applicator moves forward. The centrifugal force generated by the rotation flings the granules outward, allowing for efficient coverage of large areas, which is especially beneficial in applications such as lawn fertilization or pest control.

In contrast, other types of applicators, such as drop spreaders, primarily deliver material directly beneath the equipment and are more suited for narrower application patterns. Handheld applicators, while useful for small, targeted areas, lack the capacity and width of coverage that a rotary spreader provides. Mechanical sprayers are designed for liquid applications and do not apply granules effectively, making them unsuitable for this type of granular application. Thus, the rotary spreader's design uniquely qualifies it for wide swath applications.
