Best Lawn Dethatcher and Aerator 2021

You can’t have a beautiful lawn without hard work, but at the end of the day, you will be rewarded. Unfortunately, most homeowners forget about one simple rule: If your lawn is dying or dead, it needs to be aerated and dethatched.

The entire surface of your lawn has an intricate network of roots. Some roots absorb water and some roots pull out nutrients for the grass. These processes must occur simultaneously, and this is why it’s crucial to aerate once or twice a year along with dethatching (at least three times per year).

To have a healthy yard you need to have a healthy root system. When you attend to these matters, your lawn will always be brown free and lush green all summer long.

What is Lawn Dethatcher and Aerator?

It’s a machine that digs up your lawn and pulls out the grass from the roots. This way, it creates more oxygen in the soil and allows water to get absorbed by soil better. As for dethatching, you can use a special rake or any other tool to pull out those dead grass strands (they don’t take much time). With every pass over your yard, you’ll be able to remove more dead grass which means your tool will have less clumps of dirt attached to it as you go faster. Lawn Dethatcher and Aerator is very effective on dry patches found on golf courses and sidewalks where people walk frequently, but it works well on all lawns regardless of how healthy they already are.

How Often Should You Aerate?

This is determined by the type of soil you have in your yard. However, if you want to maintain a healthy lawn, then it’s recommended for homeowners to aerate twice or three times per year: Spring and Fall . During summer time, your grass will be thirstier so there’s no need to do this during that period (some people think that hot weather reduces grass growth but not true!).

When Should You Dethatch Your Lawn?

It’s highly recommended to dethatch your lawn once a year especially during spring before transitioning into summer. It allows grass to be able to absorb water better and grow faster.  In fact a lot of landscaping companies make money during this time of the year because a lot more lawns are getting dethatched which results in higher revenue for them…. But if you want your grass to have that ‘just mowed look’, then scheduling it once per month is definitely worth doing!

Lawn Dethatcher and Aerator comes in two forms: Push model and Corded/Battery models. For large properties, you’ll need the cordless/battery model because it will save you a lot of time that you would have spent walking back and forth with the machine. Corded version only works for small lawns such as large front or side yards. For medium to large sized properties, you should choose a mulching mower with dethatching capabilities.  Check out our list of the Best Lawn Dethatcher and Aerator for 2021:

Review:

This is honestly the best investment my fiancé and I made. We recently bought a house and our backyard was basically yellow. We thought we’d have to spend tons of money landscaping, but we found out that the grass was being suffocated by grass clippings left by the previous owner. We have a 1/2 acre so it’s taken awhile to dethatch the yard. Totally worth every penny. The machine is very lightweight (although it was a little confusing to put together). The bag is amazing and I I love that it has multiple settings.

Review:

Took a chance on this product as there was only a few reviews at the time and everyone was purchasing the Sun Joe version, and the additional width is what caught me first. Having this extra width versus the 10″ sunjoe really made a difference and I did 12k Sq ft of lawn in just about 1.5 hours with this. The bag is very small so it’s about pointless, however it does catch (had to test). It is very light and easy to maneuver, as I weighed it at 21 lbs. Ran this on a 200ft 12g extension cord and had no issues. Filled up an 8ft truck bed with thatch and debris, couldn’t be happier.

4. Sun Joe AJ801E 13 in. 12 Amp Electric Scarifier + Lawn Dethatcher w/Collection Bag, Green

LET YOUR LAWN BREATHE. Get your lawn in top green shape with the Sun Joe Dethatcher Joe AJ801E 12.6-inch electric scarifier + lawn dethatcher. Powered by a robust 12-amp motor, the Dethatcher Joe rakes a 12.6-inch wide path in a single pass to get your job done fast. Enhancing its raking ability is Airboost technology, which maximizes thatch pickup with spring steel tines that stay sharp longer for reliable performance. Use the 5-position depth control knob to tailor the raking depth from -0.4 in. (10 mm below the soil) to 0.4 in. (10 mm above the soil), depending on your lawn’s scarifying or dethatching needs. Scarifying your lawn at regular intervals cuts grass roots and encourages growth for thicker, healthier turf. Thatch is a dense mat of roots, stems and grass clippings that accumulates on lawns over time, blocking the flow of water, oxygen and vital nutrients. It is important to periodically remove thatch in order to keep your lawn green and healthy. While ordinary manual rakes are tiresome to use and not very effective, the electric Dethatcher Joe starts instantly with the push of a button and easily gets the job done without polluting the atmosphere with toxic carbon emissions. No gas, oil or tune-ups make the Sun Joe Dethatcher Joe your green choice for greening your lawn. ETL-approved. 2-year warranty.

Review:

This thing works really well. It’s better than most dethathers because it also has a Scarifier blade. It has 2 interchangeable blades, one for scarifying (cutting up the lawn, aerating it and getting rid of moss) and one for dethatching (scraping and loosening debris, dead grass and thatch from last season) It also has a bag – but I used mine without the bag … the bag was filling up too fast. You would be surprised how much detritus this thing will find in your lawn…bags and bags and bags of dead thatch. It’s best to seed after you scarily / dethatch … this is the first season I’ve dethatched out of 8 years I’ve lived in my house. My lawn has never been greener than this year.

Review:

The bag is a joke if you have heavy thatch, literally will fill up completely in a couple of feet, that being said, it works amazing. Ignore the bad review with the person trying to use it as a lawnmower because it clearly isn’t and says so in the description. For the price it’s absolutely worth it. Leave the bag off and leaf blow the thatch when you’re done

In Conclusion:

Finding the right mower for your small yard can be a tough decision with all of the available options. It might be a good idea to see how long it takes to mow your lawn. You may need more or less run time for some of the options above. The purchase of an additional battery could save you a lot of head ache and wasted time by adding the extra power you will need for your small yard.
