What is one characteristic of rotary spreaders?

1. More precise placement of pesticides

2. Uses spinning disks to distribute material

3. Requires more water to operate

4. Limited to small applications only

The correct answer is: Uses spinning disks to distribute material

Rotary spreaders are designed to distribute materials evenly over a large area, and they achieve this by utilizing spinning disks. The mechanism involves the rotational motion of the disks, which flings the material outward in a broad, controlled manner. This feature allows for efficient and wide coverage, making rotary spreaders particularly useful for applying granular fertilizers, herbicides, and other types of pesticides in a way that ensures even distribution over lawns, fields, and other surfaces. The ability of rotary spreaders to cover larger areas quickly and effectively contrasts with more precise application techniques used by other types of spreaders, such as drop spreaders, which are better suited for targeted applications. Thus, the characteristic of using spinning disks for material distribution is fundamental to the function and efficiency of rotary spreaders in pesticide application.
