For what purpose is a power rake primarily used?

A power rake is primarily used to remove thatch from lawns. Thatch is a layer of dead grass, roots, and debris that accumulates on the surface of the soil, and if it becomes too thick, it can hinder water, nutrients, and air from penetrating down to the grass roots. By using a power rake, homeowners or groundskeepers can effectively pull up this unwanted material, thereby promoting healthier grass growth and improving the overall condition of the lawn. This tool works by using rotating blades or tines that break up the thatch and mix it into the top layer of soil, where it can decompose.

While aerating soil is also beneficial for lawn health, the specific function of a power rake is not aimed at aeration but rather at thatch removal. Fertilizing lawns and seeding new grass focus on promoting growth, which is different from the main purpose of a power rake. Thus, the tool's primary design and function make it an ideal choice for addressing thatch buildup.
