Power raking removes thatch, a tight mat of dead rhizomes, stems and roots, which builds up under the surface of a lawn. Some thatch is beneficial to lawns, but too much blocks water, air and nutrients from reaching the soil. If thatch gets thicker than 1/2 inch deep, the roots grow in the thatch instead of the soil.
Many homeowners have the misconception that dethatchers and power rakes are two names for the same machine. Dethatching is less aggressive and removes small amounts of thatch from a lawn that is mostly healthy. Power raking is more aggressive and usually reserved for lawns with a large amount of thatch.
Likewise, what is the best time to power rake a lawn? Most lawns should be power raked in the late winter or early spring, before the grass begins to green up. Cool-season grasses, such as bluegrass, should be power raked in the early fall. Power raking outside of these times can potentially damage your lawn by removing living turf during growing season.

Walk around for awhile and see if the ground feels firm. If it feels spongy, or almost bouncy, that’s a sign that the thatch has gotten too thick.
