After realizing that dense thatch was likely the cause of my stunted grass' health, I decided to buy this machine. I leave the clippings on my grass, which likely caused TOO MUCH thatch. At first you'll think that $150 is too much money to spend, but if you are spending $400 a year on TruGreen or even $200 on DIY fertilizers, and you aren't dealing with the thatch, eventually your grass' health will plateau.
If you have ever tried to rake out the thatch with a metal rake, you know that it is a back-breaking affair (if you are doing it right). Heck, you'd have to pay a college kid for 10+ hours to de-thatch the yard area that I just cleared in well under an hour. Multiply this cost times the # of uses you'll get out of it over the years (including friends/family yards if you're a nice guy), and it's a no-brainer. It really does a fine job of removing the thatch, and not tearing up your existing grass either (it does pull up "some" but not enough to worry about). It feels like you are "vacuuming" your yard, that's how easy it is to use this thing (it's self-propelling, just don't stop or dig in anywhere too deep).
Also, I was going to overseed this spring, and if you watch how much you are pressing down into the grass, you can just scratch the top layer of dirt (especially in bare areas), so after you rake up the thatch, apply some fertilizer (with no weed killer obviously) then just spread the grass seed & water!! This will very lightly graze the surface (more so if you press down & dig in, ie on bare areas etc). No need to spend hours raking the topsoil...I mean, you could spend hours raking the top soil, and it would probably do a slightly better job, but do you really have hours to spend raking top soil? I just ran this machine, raked up the loose thatch, & threw down the seed in a few hours...if I had waited for when I had time to do a full weekend of raking, I would have missed the spring rains that are about to hit (to help the seeds). Throwing a big bag of grass seed down after using this to clear the thatch just makes sense depending on the condition of your yard. I'll try to post a photo in a month or two to see how much this helped.
I uploaded a before/after pic, & here are some (hopefully helpful) tips:
1. You MUST use a proper extension cord plugged into an adequate outlet. All the complaints on here about "over-heating" are from people that didn't follow the SPECIFIC instructions about cord gauge (or using an outdated outlet on an old garage etc). The instructions say that the machine WILL overheat if you aren't supplying the proper electricity.
2. The instructions say that you aren't supposed to use this on hills over 15 degrees. I was able to use it on a steeper hill just fine (the machine basically propels itself up the hill). This is a tool and just like any other tool, you can use as needed once you understand how it works. Just going "up & down" the hill (not sideways) worked for me. Basically, don't dig in too long or deep at any time, just pay a bit more attention while on a hill is all.
3. The little "kick plate" on the backside of the machine kept getting forced off the holding screws by a mass of thatch. So, I just left it off, works fine (better actually). Sure, if you run over some rocks they might get spit backwards at your feet, but hopefully you aren't wearing flip flops:)
4. The machine will effectively "mow" your grass at the height of the spinning tines. If you are over-seeding, you are supposed to mow the grass as short as possible anyways, so that you don't have to mow for as long as possible to let the new grass grow in. This is perfect for that...the grass is basically cut short and the top layer of soil is very lightly agitated, which, saves you another hour or three from having to manually rake to loosen the soil. At least that's how it worked for my beat up yard, if you have picture perfect dense grass, you may not get this benefit, not sure...is the dirt "perfectly" loosened up by the machine? Probably not, but it's definitely better than the time I had available (none) to do it perfectly by rake (while at the same time, addressing the main thatch problem...a big bag of grass seed isn't that expensive, just throw it on when done with some fertilizer)
5. The instructions say to start off with the height of the tines at the highest level, and then as they wear down, lower them (which makes sense). Also, the machine ships with an entire bag of replacement tines, which is really a nice touch. Another reviewer said to use the "high" level on the hills, and the "low" setting on flat ground to dig in more, your call...
6. Instructions say not to have kids or dogs within 50? Man, the silly things companies have to say these days to protect themselves from lawsuits. My dog would be upset if I left him inside for a day of yard work...

So I typed into Amazon 'dethatcher' thinking we would get the dethatcher rake. The neighbor owns one & I thought if my husband and I each had one we could get the yard done even quicker. However, I came across this gadget. At first I thought no way am I spending over a $100 on a tool I'll probably only use in the fall and what if it sucks? But then I saw the reviews and figured over 500 of my fellow Amazon shopper can't be lying. So out of desperation to save time and back breaking work we bought it.
OMG were we right with this purchase. In one day we got out money's worth. We used it and 2 of our neighbors used it. In our yard which we did a light dethatch last year with rack, prior to that I doubt the previous owner did much. This tool was able to pick up years and years of dead grass. I feel like the aerating and seeding was much more useful this year by getting rid of all of this.
The tool is easy to use. I assembled in about 5 minutes and both my husband and I were able to easily use the product (Add in I am 5 months pregnant) It is light weight. The slower you go the more efficient it gets with getting all the old stuff that is built up. It will not tear up good grass. You can adjust height like a lawn mower to use to your liking. Best yard product we have ever ever ever ever part. Worth every penny!

This thing worked great. Yada, yada, yada. Even on the highest setting it took a ton of gunk out of my lawn.
Only complaint is the darn safety switch button. Before squeezing the handle to turn the thing on, you have to push a big button awkwardly placed near the side of the handle. And you don't want to leave it running in one spot, so you always let go of the grab bar at the end of a swipe, shutting it off. Between fumbling with the cord and maneuvering the machine, the button was too much to take. So I zip-tied it down. Take that, lawyers!

So far, I did the backyard with this device. We lost large sections of the lawn because the grass was suffocated by some kind of vine-like weed. The dead grass and the weeds had to be pulled up so we could reseed in the fall. This dethatcher was everything I wanted it to be. Years ago, we had used a special attachment to a tiller to do the dethatching. It ran on a mixture of gas and oil, took 20 minutes of heavy cord pulling to get it to start, was extremely hard to control, worked better going backwards, made a lot of noise, and smoked like crazy. Eventually the thing wouldn't start at all. In contrast, the Greenworks dethatcher starts in an instant, is easy to push and control, is extremely quiet, and is powerful enough to do a better job dethatching the lawn than the gas and oil device we once had. Of course, the electric cord can be a nuisance. You have to perfect your style in order to avoid accidentally going over it. If this thing was rechargable but still light and powerful, it would be perfect.
The 4 year warranty is impressive. However, I still hope this device lasts a lot of years without any problem. The mechanism and build appear to be very simple. But maybe simple is better. A rubber sheet that hanged down in the back of the dethatcher dropped off after several minutes of use. Although it contains screws and wingnuts, I couldn't figure out where it was attached. The owner's manual and the picture on the box does not display this part at all. So I decided it wasn't important. The dethatcher works fine without it.

Here is my experience with this machine. The local equipment rental charges $100 a day for a gas powered de thatcher. I figure I would spent the money on this and if it lasts more that a few days I got my money's worth. I used this on my 8,000 sq ft lot with a huge back yard going over it twice as my moss invasion was out of control. This thing had no problem ripping up all the moss and dead thatch. The only issue was the rubber flap in the rear came loose and fell off but it reattached easily with wing nuts. I left it off so the material would come out easier. Just wear pants cause any rocks will come out as well. Really my only gripe is getting a system down so I'm not having to toss the cord out of the way every pass. It's electric so deal with it! All in all a great machine for the money. Light enough to toss out of the way in the rafters or attic for next season and even comes with extra tines!

It appears to be fairly solidly built and is shipped well packaged. Took about 5 mintues to unbox and put the handle on before I was ready to go. It has penty of power, just be aware of the gauge (thickness) of the extension cord you are using. Longer cord runs may need a thicker extension cord.
The unit has several depth settings and brings up an enormous amount of material on each pass. Old material flows out the back of the unit and the unit has enough power to "pull" itself forward so there is very little effort required to push this thing. Being electric there is no gas to mess with, is extremely quiet, and I know I can put it away for the year and not worry about a gummed up engine come next spring. The only drawback is of course that also being electric, it has a cord you need to drag around. If you take your time this isn't that big of an issue. If it comes unplugged, as mine did several times, just plug it back in and go. You do also have to move it to avoid running it over, but again just paying attention solves most of the problem. It is worth the little extra cord effort as this thing outperforms the traditional dethatching rake and also the attachment they sell to put on your lawn mower (I have both of those as well and this unit crushes them).
Overall a good unit that works well in a small yard setting.

I bought this so I didn't have to rent the very heavy dethatching machines from HD and I couldn't be more happy. This machine is very light and easy to use. The hardest part is keeping the extension cord out of the way but its really no big deal. Check the bolt and wing nut the holds the back flap on because I didn't and one fell off and is now gone but again no big deal because any hardware store has them. I actually removed the flap and I feel that the machine works better without it because now the thatch has an easier path out of the machine. I'm sure the manufacturer doesn't recommend it so it's really up to you. I did one pass on medium when the grass was bone dry and a lot of dust was kicked up along with the thatch. I filled almost 3 50 gallon bags with thatch even though I did it last year with the heavy duty one. But looking at the grass there was still a lot of thatch so I lightly watered the lawn and let the grass blades dry but the thatch was still damp and I did a second pass at the same height. I was amazed how much more thatch came out as you can see in my picture. Again I don't think the manufacturer recommends this but the machine was able to grip the thatch better and remove it when it's slightly damp not saturated just damp. With the ground being damp this also creates little channels in the soil from the tines for the grass seed to sit in which allows more contact with the soil and better germination. Hopefully this machine lasts me a long time but even if it lasts 2 or 3 years it still paid for itself.

I knew I needed to dethatch the front lawn but I checked on rental prices and when I considered this is something that needs to be done every year, this purchase made a lot of sense. It really worked well. Our lawn was browning out because of of the deep thatch , but after using the machine and doing some aeration with a simple pitch fork m the lawn has never looked better.

If you follow the directions, this works fantastic. However, the directions are not the best. For example, when assembling the unit they don't mention that you need to slip the cord manager on the lower handle BEFORE attaching the top handle. Would have saved me disassembling and reassembling. Same thing with the rubber pads the lower handle rests on. Also, the height adjustment on the wheels is counter intuitive...setting it at #1 is the highest setting, not the lowest. When operating, just keep all four wheels on the ground (yes, there are 2 hidden wheels on the back) this will work nicely even on uneven slopes. Keep it moving, or it will tear a bald spot on the lawn, and definitely start on the highest setting. Get the right gauge extension cord, it will save lots of heartache.

My husband and I have a really big lawn here at the new home that we bought last year. We have been trying everything to bring the lawn back to life this year, but it has been a really trying process. We have done a little research and are trying all of the suggestions that we have read. We were getting ready to do a bit of re-seeding this morning. Before we did, we tried out this dethatcher. I ordered it last week and with my Prime shipping, and it arrived quickly and was easy to set up. My husband showed me how to use it and then I took over. This is very light and is easy to move around. Now, my #1 suggestion is not to use this the same way that you are used to using a lawnmower. Instead, I found that it is easier to use this in smaller sections (maybe 4 feet wide at a time). I did this and worked my way down the yard. This allowed me to pull all of the dead and tangled grass all into one row at the back of my lines, if that makes sense. I would go forward four feet, and then pull back, pulling back to the same distance each time. This created a line of piled grass to take up. It was a lot easier to rake up this way. If you use this like a mower, it will spread out all that is pulled up and you will have to rake the entire lawn. Going in small sections and backing up to the same line each time allowed cleanup to go a lot smoother. This really 'untangled' all of our grass/roots and it was a great thing to do prior to replanting. I was worried that this would dig too deep; however, this does not go too far down, yet it does stir up things and sort of brushes the lawn out. I am really happy with this and my husband and I plan to use this twice a year. Although this is not self-propelled, it is incredibly easy to push and pull because it is so light. It didn't get stuck at all and we are happy to have this.
