Frequently Asked Questions

What Does a Dethatcher Do?

A dethatcher removes thatch—a layer of dead grass and debris that builds up around the base of your lawn. Thatch blocks water, air, and nutrients from reaching the soil. Regular dethatching promotes healthier, stronger grass growth by improving nutrient absorption.

Is This Dethatcher Self-Propelled?

No, our dethatcher is not self-propelled, but its lightweight design makes it easy to push and maneuver. The raking action may pull it slightly forward, but you’ll still need to guide it for best results.

When Is the Best Time to Dethatch my Lawn?

The ideal times are:

Late spring (after active growth begins)
Early summer (before extreme heat)
Early fall (to prepare for winter)

Avoid dethatching in hot, dry weather or when the soil is too wet—moist (but not soggy) soil works best.

Does this dethatcher have a collection bag?

No, our dethatchers do not include a bag because thatch is too light to be effectively collected. Instead, simply rake up the loosened debris after dethatching.

Can I Use a Dethatcher to Aerate Soil?

No—dethatching and aeration serve different purposes:

Dethatching removes the thatch layer to improve water/nutrient absorption.
Aeration removes small soil plugs to reduce compaction.

For best lawn health, consider doing both (but not at the same time).

Can I get longer replacement tines?

No, we currently only offer one size at 1 3/4 inches.

Can I use it to cut weeds?

No, this is strictly a dethatcher. It will not cut weeds. Dethatching removes the thatch, buildup of organic debris on the surface of the ground, which prevents water and nutrients from getting into the soil, removing it allows this to happen more easily, so you get a stronger lawn growth. For cutting weed management we would recommend our string trimmer units.

How short does my grass have to be prior to use?

We advise that your grass be mowed to its shortest recommended seasonal height prior to using the dethatcher.
