What factors affect the amount of product applied by a rotary spreader?

• A. Applicator speed, terrain, and flow rate of the granules
• B. Room temperature, humidity, and air pressure
• C. Operator height, color of granules, and weather forecast
• D. Brand of spreader, fuel type, and maintenance schedule

Answer: (A)

The amount applied by a rotary spreader is governed by how fast you move, how much material the spreader releases per unit time, and the surface you’re spreading on. If you set a higher flow rate, more granules leave the hopper each second; if you move more slowly, those granules cover more area per unit of time, increasing the product per area. The terrain affects how evenly and where the granules actually deposit—slopes, rough ground, or obstacles can change coverage width and introduce gaps or clumps, altering the effective amount applied across the area. Other factors like room temperature, humidity, air pressure, or weather forecasts don’t determine the quantity released per unit area; they can influence drift or performance but not the basic rate set by speed and the spreader’s flow setting. Brand, fuel type, or maintenance affect reliability more than the immediate application rate.
