Which statement describes a rotary spreader?

• A. It uses a spinning plate to distribute the pesticide in a much wider swath than the width of the spreader
• B. It relies on gravity to drop granules in a straight line
• C. It blasts granules through a narrow nozzle
• D. It only works for seeds, not pesticides

Answer: (A)

The key idea is how a rotary spreader distributes material. A rotary (or broadcast) spreader uses a spinning plate or disk inside the hopper to fling dry granules outward by centrifugal force. This action launches the granules in many directions, creating a distribution swath wider than the spreader itself. That outward, wide coverage is the hallmark of a rotary spreader, and it’s designed for dry granular products like pesticides, fertilizers, or seeds. In contrast, a gravity-fed system drops granules straight down without spinning, which yields a much narrower, direct fall. A nozzle-driven setup blasts material as a spray, typically liquids, not granular solids. And rotary spreaders aren’t limited to seeds; they’re designed for granulated products and are commonly used for pesticides and fertilizers as well.
