Worx Wg850 Corded Electric Dethatcher

Best Dethatchers in 2022 – How to Remove Thatch From Your Lawn

Our Review

The WORX WG850 corded electric dethatcher is a top selection because it is lightweight and is easier to store with its fold-down handle.

The motor delivers plenty of power to handle all your dethatching needs without bogging down, which avoids frustration. While it doesnt have a self-propelling feature, its easy to push along on the large wheels, so you dont have to struggle while dethatching the lawn.

I like that this dethatcher comes complete with a collection bag, which eliminates the hassle of raking up the loose thatch off the top of your grass. I also appreciate the lock-off switch, which allows you to quickly shut off the unit in the event of sudden safety concerns like a pet runs near.


  • Corded unit with strong motor delivers powerful, consistent results
  • Quiet, environmentally-friendly operation reduces noise and pollution
  • Handle can be folded for compact storage
  • Tine depth can adjust into three positions for better ground contact
  • Quick shut-off switch avoids dangerous contact with moving tines


  • Bag fills quickly, which means more stops and time to finish the job
  • On uneven ground, the machine tends to dig deeper in places which can cause holes if youre not careful

Bottom Line

The WORX WG850 14 Corded Electric Dethatcher is the perfect choice for homeowners looking for the convenience of a more powerful yet quiet dethatcher that doesnt require gas or battery charging. The foldable handle for easy storage is another nice perk.

Preventing A Thatch Problem

Since a thatch problem is the result of new organic matter building up more quickly than the older organic matter can break down, avoid practices that result in your grass growing too quickly. For example, do not:

  • Water the grass more than is necessary
  • Feed it with a fertilizer that is high in nitrogen

Staying away from the unnecessary use of pesticides also may help you avoid having to dethatch your lawn. Worm presence helps in the decomposition of thatch. Pesticides, unfortunately, kill worms.

Where Does Thatch Come From

Reviews Root

Thatch occurs naturally. It builds up whenever you mow the lawn or allow leaves to accumulate on the grass. However, if there is poor drainage, too little water, cold soil temperatures, or poor soil aeration, this can cause thatch to accumulate. Chemical pesticides and synthetic fertilisers may also contribute to a persistent thatch problem.

How Often Do You Aerate Your Lawn

How often to aerate, depends on the type of soil you have in your lawn. If you have a lot of clay in your soil or heavy traffic in your yard, you will want to aerate your lawn at least once, preferably twice a year.

If you have sandy soil, with exceptional drainage, you can most likely get away with lawn aeration once every two years. With that being said, to maintain a fully nourished lawn experts recommend aerating your lawn a minimum of once a year.

What Is The Difference Between Aeration And Dethatching

The question of dethatching or aerating is one that comes up often in the minds of homeowners. But which process do you go for if youre on the hunt for a lush-looking lawn?

Both power raking and dethatching aim at removing excess thatch in the lawn. A power rake is good for getting rid of the thick layer of debris lying on top of the soil while a dethatcher is good for removing a thin layer of decomposing organic matter that forms the topmost part of the soil in the lawn.

Power raking is a more aggressive process of removing thatch and dead matter in the lawn while dethatching is a light process that removes just a thin layer of debris that makes fertilizer absorption poor.

A dethatcher is usually spring tines that rotate and dislodge the layer of thatch and dead matter on the lawn while a power rake is usually mechanical with a dethatching blade that has rotating flails. The flails aggressively dig up thick layers of thatch from the lawn.

A dethatcher is a small machine that looks almost like push lawnmowers. Some come as extensions that you can attach to a lawn mower. On the other hand, a power rake is a heavy-duty machine that removes large amounts of thatch from a lawn.

Pro tip: A power rake can be very unforgiving on your lawn. Try to do it early to allow your lawn to heal before going dormant.

Why Do I Need A Dethatcher

Thatch is a natural part of your turfs health. Thatch is a mixed layer of living and dead organic material including shoots, stems, and roots that sits in between the live grass blades and the soil layer. As this layer grows thicker and denser, roots begin to grow into the thatch itself instead of the soil.

Dethatchers are tools that use rake-like steel tines to slice through the thatch layer and remove some of it. They come in different forms: hand tools, attachments for your larger power tools or tractors, and full-sized machines that can be electric or gas-powered.

Dethatching should be done every year to prevent thatch from growing too thick. The best time for dethatching is fall or early winter, when the grass and thatch has gone through a full year of growth but before the soil freezes. Dethatching in the spring rips up turf that is often still dormant and will be unable to recover after winter injury, snow mold, and ice damage. It can also bring up noxious weed seeds and crabgrass to set your lawn up for a future infestation.

Q: Do You Really Need A Grass Dethatcher

Sun Joe Green 13"  Corded Electric Lawn Dethatcher w Collection Bag ...

A: Only if you want your lawn to look good. Thatch is something thats going to happen. And if you dont engage in periodic dethatching it will wind up strangling your lawn and causing it to take on an increasingly brownish, brittle character. So if you want your lawn to look good year after year then yes, you need to use a yard dethatcher occasionally. How occasionally? Some lawns may need to be dethatched every year. While in other cases you may go a couple of years between thatching the grass. But even grass types that dont naturally produce a lot of thatch will at some point need tending. Keep in mind too that, in most cases, the longer you wait to remove the thatch the more difficult the process is going to be. It may get to the point that youll need to both dethatch and aerate the core of the lawn as well to revitalize it.
