One advantage of rotary spreaders is that they:

• A. Cover a large area quickly.
• B. Require frequent recalibration.
• C. Create an even spray pattern across the swath only in the center.
• D. Are limited to small areas.

Answer: (A)

Rotary spreaders are designed to fling fertilizer outward as the spreader spins, creating a wide dispersal pattern. That broad throw lets you cover a large area in fewer passes, which is a major time- and labor-saving advantage for treating lawns, athletic fields, or other expansive turf. With adjustable gate settings and a wide spray width, you can achieve substantial coverage quickly, making them particularly efficient for big areas. While calibration remains important for accuracy, the standout benefit is the ability to cover more ground per pass. The notion that distribution is only even in the center isn’t accurate, and rotary spreaders aren’t limited to small areas, so those points don’t describe their primary advantage.
