What type of spreader projects fertilizer outside the wheels?

The rotary spreader is designed to project fertilizer outside the wheels, which allows for more even distribution across a larger area. This type of spreader uses a rotating disk to fling the granules of fertilizer outward as the operator walks behind it. The spinning action creates a circular pattern that helps cover areas efficiently, making it ideal for larger lawns or gardens.

In contrast, a drop spreader releases fertilizer directly beneath the spreader, which is effective for precise application but does not project material outside the wheel tracks. Handheld spreaders, while useful for smaller areas, typically provide limited range and may not distribute evenly over larger spaces. Mechanical spreaders can refer to various types of application equipment, but they are not specifically characterized by projecting material outward as the rotary spreader does. This unique action of the rotary spreader enhances its functionality for spreading fertilizer widely and evenly.
