Greenworks Electric Dethatcher Review (+ How-To Guide)

greenworks dethatcher compared to sun joe

My Greenworks Dethatcher is a lawn tool that I became obsessed with the second I started using it. Dethatchers work by pulling up old, dead grass that is embedded in the soil of your lawn. This provides the most satisfying experience ever when you use it.

This dead grass, or “thatch”, prohibits your living grass from getting nutrients and can cause your grass to appear thin. Dethatchers have historically been tough-looking heavy rakes that you could pull across your lawn by hand. 

Let’s get started!

When and why to use a dethatcher on your yard

Dethatching your yard is one of the most satisfying lawn tasks. If you are one of those people who likes pimple popping videos or loves to peel off the plastic of a new appliance, then dethatching will be your jam.

My Greenworks Dethatcher.

It basically pulls up all this dead grass that is stuck to your lawn and pushes it to the top of your yard. You can almost hear your yard start breathing again. 

The time of year to dethatch your yard is just prior to the aerating and overseeding process. For us, this time of year is in October, but can vary depending on where you live. Dethatching right before aerating and seeding gives the best possible chance for your seeds to make contact with soil. 

THIS is thatch.

First, you pull up the dead grass with the dethatcher. Once you have pulled all of this up and gotten rid of it, then you can aerate. You will want to aerate your lawn immediately after dethatching, then overseed the lawn. This will put seed straight on the open soil and give it the best success to grow into a thick, luscious lawn. 

The Greenworks Dethatcher features

The Greenworks dethatcher comes in at a slightly lower price point than the Sun Joe Dethatcher. It is also one of the most popular dethatchers available on the market. Let’s review what makes this so popular.

My experience using this dethatcher

I used my Greenworks dethatcher for the first time this year on my relatively newly sodded lawn in Austin, TX. Despite only having a year or two of life, I got an insane amount of thatch off the ground. Here’s how it worked.

The Greenworks Dethatcher comes with an easy push to start functionality. This push to start feature allows for guaranteed starts after being stored through a cold winter. It boasts a 14 inch width for the tines (the little spikes that pull up thatch), which gives it an immediate advantage over some of its competitors. 

The handles fold in and allow for easy storage. As do other dethatcher in its class, it does not use any batteries and requires no charging. Rather, the Greenworks dethatcher requires an extension cord. As I mentioned in my last dethatcher review, a fifty foot extension cord is recommended. Longer extension cords can become quite heavy and cumbersome to move throughout your yard.

Comfort is important to me, and as a tall person I highly value the longer handles that come with the Greenworks dethatcher. These are much more comfortable and help me stay out in the yard longer. 

This is surprisingly powerful

Not sure what kind of power you can expect with an electric dethatcher. This is not a gas guzzler and is not meant to really provide any power. But it does have 10A of power running through it. It does not have a self propelled feature persay, but does inch forward with the help of the thines moving forward trying to pull up grass. 

When I was using this dethatcher and testing out the power, I noticed that it wasn’t an issue – the issue was moving slowly, which is basically just what I have to do when I use a dethatcher.

This dethatcher is simple and durable

While most people scoff at plastic and electric lawn tools, I think this one really does have great durability. I have not put too much use into mine, but have heard others talk about the longevity of the tines. The tines are the little pieces of metal that actually pick up and displace the dead grass on the bottom of the dethatcher. You would expect some wear and tear, but they appear to last quite a while.

This is really a simple machine that does not require any maintenance. When broken down to its functional components (kind of like active ingredients in supplements), it is just an electric power circle of little spikes. Not much can go wrong.

This one was really easy for me to break down and fold in half in my garage, basically just like how it came out of the box.

My yard now looks way better after using this

My Greenworks dethatcher will pull up the dead grass from the top of my yard without fail. As long as it is moderately dry outside, it will not have a problem getting to the thatch and giving your grass some room to breathe. 

Clean-up, however, is a different issue. Compared to several other electric dethatchers, the Greenworks dethatcher does not come with a bag. Do not fret! The bags that come with the dethatchers are almost comically small.

I was surprised with the amount of grass that came up from this tool. You will likely fill your bag after about 5 to 8 feet of pushing. With that in mind, most people use all dethatchers without bags. 

To clean up, simply grab your mower, put it on a high setting, slap the bag on, and do a quick run over the yard to suck up all the thatch. You can always use a blower, a heavy duty rake, or whatever you would like to clean up the yard. 

Comparison: Greenworks dethatcher vs Sun Joe dethatcher

If you are looking at an electronic dethatcher online, you are likely picking between these two. Both are the top sellers on Amazon and combined have over 20,000 reviews. Both look very similar and both have almost 5 stars on Amazon. 

Luckily, I have owned both and even tested them side by side to see which one did a better job of pulling up thatch.

Functionality and power

To compare the two, let’s start with functionality. They function identically. Both are powered by an extension cord, move at the same speed, and electronically pull up thatch. The advantage goes to Greenworks here because they have a slightly bigger tine deck. 14 inches in the Greenworks vs 13 inches in the Sun Joe dethatcher. You will get more out of each pass using the Greenworks.

Add-ons

Something else to consider when comparing these products is the availability of add-on features. Greenworks offers zero add ons to their product, whereas Sun Joe offers a scarifier and a bag. As mentioned previously, the bag is meaningless and most people trash it. The scarifier applies blades to the soil to help cut through and tough thatch and provide a modest amount of aeration. The advantage in this category goes to Sun Joe.

Cost and value

As of right now, the Sun Joe dethatcher costs around $150 and the Greenworks dethatcher comes in right around $130. Both are going to last a long time and both are of very similar quality. If it were me (and it is me), I am going with the Greenworks. 

Overall comparison: Greenworks dethatcher vs Sun Joe dethatcher

Y’all this is a relatively easy one for me. I will save $20 and go with the Greenworks dethatcher if I had to do it over again. It operates the same, has great durability, is slightly wider, and a good bit cheaper.

Sun Joe Electric Dethatcher Review (+ Full Video)

The Sun Joe dethatcher AKA Sun Joe AJ801E, is a tool that has recently blown me away. I had never used a dethatcher before – and boy was I missing out. Not only on the results but on the complete satisfaction this tool provides.

Ever gotten really close to the soil and wondered what all that dead grass was doing? After it rains it is all of the super soggy, dirty, twisty grass that sits at the base of the grass and clogs it up. I can tell you what it is doing – it is called thatch and it is clogging up the soil and suffocating your lawn just like it was mine.

When I started dethatching my lawn at least once per year, especially before I aerate and overseed, has yielded amazing results. Getting rid of those dead strands of grass gives my yard room to breathe, take in nutrients, and grow more luscious throughout the season.

How I tested the Sun Joe dethatcher

In short, I bought it and recorded a long video of myself using it in the yard. So if you want to see it in action, check it out on Youtube.

But I have about a half acre of tall fescue and I took this puppy through my entire yard – twice. It dug up so much dang thatch that I had to put it in my trailer. When I was evaluating it, I was mostly looking at its power, convenience, durability, and value (price to performance ratio).

It was pretty sweet.

Sun Joe dethatcher features and benefits

At first glance, the Sun Joe dethatcher appears to be a big plastic box with a metal bar. In fact, it looks weak and wimpy. It feels kind of unsturdy and cheaply made.

Do not be fooled. This thing is a workhorse! You will notice once you get it going that it has some serious power to pull up the dead grass. Yep, that same dead grass that broke my back with the rake is coming up super easily by a plastic box. No reason to feel embarrassed.

Plug and play

The downside of this dethatcher is that it needs to be plugged in to operate – it is not battery powered. A nice, long extension cord will help get the job done. I recommend a fifty foot extension cord. One hundred foot extension cords tend to get really heavy and difficult to maneuver.

Clean-up after dethatching – bag or no bag?

The Sun Joe dethatcher leaves quite the mess behind. I was be surprised to see the amount of thatch that comes up from beneath my grass. That being said, Sun Joe provides a bag that can be mounted to the dethatcher. I suggest using this to clean as you go. Otherwise, go over the loose thatch with your mower and collect it in that bag. Another option is to grab the rake, but obviously would be a last resort.

Sun Joe Dethatcher Durability

At first glance, this chunk of neon green plastic that is only about 13-15 inches wide does not look like it would be super durable. Frankly, that is exactly what I thought when I first looked at the Sun Joe Dethatcher (or really any Sun Joe product).

The truth is, the little throngs at the bottom poking out are called tines. The tines on this machine are, in fact, super durable. These tines will work to dig up all of the thatch and leave my lawn looking great. Truly, the plastic casing and wheels are deceptive, as they simply serve as a cover for an otherwise low-output (meaning not getting super hot or vibrating) tool. I have no concerns with the durability of this equipment and have had zero issues with tines. The tines can also be replaced if needed, giving the Sun Joe dethatcher a high durability ranking.

Setting expectations

While the Sun Joe dethatcher is a powerful tool that will save my back, it isn’t for everyone. If you have a massive yard, you are better off getting a commercial size dethatcher that can be hooked on to the back of a riding mower.

Assembling the Dethatcher right out of the box.

To level-set expectations, the Sun Joe dethatcher has a width of almost 13 inches ranging up to 15 inches with the largest model. This is not going to be “a few passes in the yard and you are good to go”. It will require you to move relatively slowly and make many passes to cover the entirety of your yard. But boy, will you be surprised by the amount of thatch you pull up. 

It is ideal to use the dethatcher on your yard right before you aerate and seed. This gives your yard a fresh slate to work off of for the most aeration and overseeding. All of those gaps that you notice between the blades will become filled in (if only this could happen to my hair).

The scarifier attachment on the Sun Joe Dethatcher

This machine also comes with a scarifier attachment. Honestly, I had never used or even heard of a scarifier before I used the dethatcher. It basically looks like someone removed the blades out of my blender and put them in this machine.

Basically, the scarifier cuts little grooves in your yard to somewhat aerate and cut through small roots and other tricky pieces that might give the dethatcher a hard time. In my experience, I would just use the dethatcher then switch over to a normal aerator to get the job done prior to seeding. 

Renting vs buying the Sun Joe Dethatcher

This is a very easy question for me to answer. Simply put, once I used the dethatcher on my lawn one time, I was addicted. It is incredibly satisfying to pull up a bunch of old grass that has been plaguing my lawn. 

The Greenworks dethatcher is the main competition – we own it, too.

Renting a Sun Joe dethatcher simply is not worth it. This is something I will want to do to my lawn every couple of months. The dethatcher is relatively inexpensive compared to other lawn items, ranging from $150 to $200 depending on where and when you buy. It is on sale on Amazon right now, which is where I got mine.

The Cordless Sun Joe Dethatcher: A new version

For an additional $100 or so, you can purchase a cordless dethatcher. I do not generally recommend getting the cordless version and I will explain why.

The range of the batteries on these will not get me much further than the limit of an extension cord. Meaning, I will not get much of a benefit besides not having to worry about pulling around or tripping over an extension cord. I also hate having clutter in my garage and already have enough battery chargers for my other tools. This comes with two batteries that will simply add more clutter, chargers, and things that I will fall and break my neck on in the garage.

Why would I buy a Sun Joe dethatcher?

I am not really sure who Sun Joe is, but he makes electric yard tools like dethatchers, pressure washers, electric air compressors, and more. Traditionally, dethatching is done with a fine rake across the entirety of your yard. Other than the damage this does to your weekend and lower back, it can put a lot of stress on your living grass. 

The Sun Joe dethatcher AJ801E provides an electronic way for you to simply scoot across your lawn and pull up all of the dead grass. This saves you time and back pain and is much more effective. 

Sun Joe also has a line of winter products, aptly named Snow Joe.

When to use a dethatcher

Dethatchers are great for people who do their own lawn care. Where I see dethatchers being most useful is at the beginning of the spring when the snow has melted. Snow plows and general use around your yard can cause dirt, debris, and rotten roots.

Another great time to use the dethatcher is right before aerating and seeding, typically around October (depending on where you live). This gives the seed fresh ground upon which to grow and takes away competing sources of nutrients like sunlight, nitrogen, and water. 

Why we started The Lawn Review

The reason we started this website in the first place was because we had so much trouble trying to find reasonable, understandable, honest reviews for lawn equipment. And it’s not cheap! After hours and hours of research, trying products and returning them, and messing up our yards – we started this site. 

We have unusual testing methods.

As people who had to learn the hard way, we want you to know exactly what you are signing up for before you purchase a piece of equipment. That’s why we are committed to providing honest, easy-to-understand reviews that mean something.
