Greenworks 27032 Review

Introduction: Why I Finally Gave In and Bought a Dethatcher

For years, I was the guy who thought a stiff rake and a good sweat were all you needed for lawn care. I have a half acre of Kentucky bluegrass and fescue mix, and every spring, I would spend two weekends bent over, yanking dead grass and thatch into piles. My back would ache for a week. I told myself it was a good workout. Then last year, after a particularly wet season, my lawn started looking like a patchy, spongy mess. Water pooled in low spots. The grass felt like it was growing on a mattress. I finally admitted that my manual raking was not cutting through the thick, matted layer of dead organic matter that had built up over three years.

I started researching power dethatchers. I wanted something electric to avoid the smell and maintenance of gas, but I needed real power. The Greenworks 27032 kept coming up in forums because of its 14 amp motor and the huge 12 gallon bag. I found one on sale and decided to pull the trigger. After using it for three full seasons on my own lawn and helping two neighbors with their much larger yards, I feel like I can give you an honest, boots on the ground review. This machine has strong points that genuinely impressed me, and it has flaws that almost made me return it on day one. Let me walk you through everything.

How I Tested It: Real Yards, Real Thatch, No Shortcuts

I did not run this thing on a manicured patch of golf course grass. My testing conditions were real and frankly, ugly. My lawn had a thatch layer measuring between one and two inches thick in the worst areas. I also tested it on my neighbor Bob’s yard, which is a 3/4 acre lot with heavy clay soil and a mix of coarse tall fescue that had not been dethatched in five years. His thatch was so dense in spots that you could barely push a screwdriver through it.

I used the Greenworks 27032 on three separate weekends. The first test was a light pass on the lowest depth setting to see how it handled loose debris. The second test was a full depth attack on the worst patches. The third test was a marathon session where I did the entire front and back yard in one go, stopping only to empty the bag. I paid close attention to how the motor performed under load, how the tines engaged with the soil, how easy it was to maneuver around flower beds and trees, and most importantly, how much thatch actually ended up in the bag versus being left on the lawn. I also deliberately tested the cord management situation because that is a common complaint with electric lawn tools.

Performance: The Motor Is a Beast, But the Bag Gives It a Workout

The 14 Amp Motor Is the Real Star

Let me start with the best part. The 14 amp motor on this Greenworks 27032 is genuinely strong. I have used corded electric dethatchers from other brands that bogged down the second you hit a thick patch. This motor does not give up easily. On Bob’s neglected lawn, I set the depth to setting 4 out of 6, and the machine tore through the matted thatch like it was nothing. The tines dug in aggressively and pulled up long, stringy clumps of dead grass and roots. I could hear the motor pitch drop slightly under heavy load, but it never stalled. It just kept chewing.

On my own lawn, where the thatch was more moderate, I ran it on depth setting 3 and it left clean, visible grooves in the soil. The tines did a fantastic job of lifting the horizontal runners of creeping grass that were choking out the good turf. After the pass, I could actually see bare soil in the lines, which is exactly what you want for overseeding. The motor is powerful enough that you can walk at a normal pace. You do not have to slow down or baby it. It just works.

The 12 Gallon Bag Holds a Lot, But It Fills Fast

The 12 gallon bag sounds huge on paper, and it is big. I can fill it completely in about 10 to 12 minutes on a thick lawn. That is both a pro and a con. It is a pro because you are not running back to the compost pile every three minutes. On my half acre, I only had to empty the bag four times total. That felt efficient.

But here is the catch. When the bag is full, the weight of the thatch makes the whole machine feel unbalanced. The bag hangs off the back, and when it is packed with wet, heavy debris, the front of the dethatcher can lift slightly. I had to slow down and be careful on slopes because the weight distribution shifted. Also, the bag is made of a fabric material with a plastic frame. It holds up fine, but the zipper closure at the top can be annoying. You have to unzip it fully to dump the contents, and if you are wearing gloves, it is a minor hassle. I would have preferred a rigid plastic bin with a quick release latch.

Six Depth Settings Give You Real Control

The six depth settings are not a gimmick. They actually matter. The lowest setting (1) is basically a light scarify that just lifts surface debris. I use this in the fall after a light leaf cover. Setting 3 is my go to for moderate thatch. Setting 6 is aggressive. I used setting 6 on a patch that was essentially a dead moss mat, and the tines dug into the soil about a quarter inch. It was effective but it also tore up some healthy grass roots. You need to be careful with the higher settings. The adjustment lever is on the side of the deck and it clicks into place firmly. It is easy to change on the fly without stopping, which I appreciated.

Cord Management: The Biggest Frustration

I have to be honest about the cord. The cord snags on the handle constantly. The handle has a built in cord retainer clip, but it is poorly designed. The clip is a simple plastic hook that sits near the top of the handle. When you make a turn, the extension cord slides out of the clip and wraps around the handlebar. I found myself stopping every few minutes to untangle the cord. I tried routing the cord over my shoulder, but the clip is too low to keep it secure. This is a common issue with many electric dethatchers, but it is worse here because the handle is a single straight bar with no dedicated cord channel. If you are not careful, you can accidentally run over the cord with the tines. I have a healthy fear of that. My advice is to use a heavy duty 12 gauge extension cord and tape the cord to the handle with electrical tape in two places. It is a hack, but it works.

Build Quality and Value: Heavy Duty With a Few Rough Edges

Durable Construction That Feels Solid

The Greenworks 27032 is built to last. The deck is made of a thick, reinforced plastic that does not flex or crack under stress. The wheels are large and have a ribbed tread that grips well on slopes. I have rolled this over uneven ground and it did not wobble or feel cheap. The tines are metal and they are held in place with a sturdy axle. After three seasons, I have not had any tines bend or break. The handle is a single piece of tubular steel with a foam grip. It is comfortable to hold, but it is not adjustable for height. I am 5 foot 10 inches and it felt fine. My neighbor who is 6 foot 3 inches had to hunch slightly. That is a minor oversight.

The Weight and Bulk Are Real Problems

This machine is heavy. It weighs about 40 pounds empty. With the bag full of wet thatch, it feels closer to 60 pounds. Pushing it is not an issue because the wheels do the work. But lifting it is a chore. I store it in my garage on a shelf, and getting it up and down is a two hand job. It is also bulky. The handle does not fold down or collapse. It is a fixed length, so it takes up a lot of floor space. If you have a small shed or a cramped garage, this will be a problem. I have seen people hang it on wall hooks, but the handle shape makes that awkward. The bulk also makes it hard to maneuver in tight corners. You cannot pivot it on the spot like a smaller unit. You have to lift the front wheels to turn sharply.

Value for the Money

I paid around $150 for this unit, which I think is a fair price for the motor power and bag capacity. You can find cheaper dethatchers with 10 or 12 amp motors, but they will bog down on heavy thatch. You can also find gas powered models that are more powerful and cordless, but they cost two to three times as much and require maintenance. For a homeowner with a medium to large yard who does not want to mess with gas, this is a solid value. The build quality suggests it will last several years with proper storage. I would not call it a bargain, but it is not overpriced either.

Who Should Buy the Greenworks 27032

This dethatcher is for you if you have a lawn that is genuinely suffering from thatch buildup. If you can pull up a handful of grass and see a thick, brown layer of dead material at the base, this machine will fix it. It is also great if you have a large yard, half an acre or more, because the big bag and powerful motor let you cover ground quickly. If you are physically strong and do not mind the weight and bulk, you will be happy with the results.

However, this is not for you if you have a small yard under 3,000 square feet. You will be better off with a manual rake or a smaller electric model that is lighter and easier to store. It is also not for you if you have a lot of obstacles like narrow garden beds, trees close together, or steep slopes. The weight and fixed handle make it clumsy in tight spaces. If you are elderly or have back issues, the lifting and maneuvering might be too much. Look for a lighter model with a folding handle.

My Verdict: A Powerful Tool That Demands Compromise

After three seasons of hard use, I can say that the Greenworks 27032 is one of the most effective electric dethatchers I have used. The 14 amp motor is a workhorse. It will tear through heavy thatch that would stall lesser machines. The 12 gallon bag is genuinely time saving, even if it gets heavy when full. The six depth settings give you the precision to go from a light clean up to a full scalp. The construction is durable and the large wheels roll well over uneven ground.

But the flaws are real. The cord snagging on the handle is an annoyance that you will deal with every single session. The weight and bulk make storage and tight maneuvering a headache. The non adjustable handle is a miss for taller users. These are not deal breakers for me because the performance is so good. I have learned to manage the cord with tape, and I have a dedicated corner in my garage for storage. But I cannot pretend these issues do not exist.

If you are looking for a dethatcher that prioritizes raw power and bag capacity over convenience and portability, this is your machine. It transformed my lawn from a spongy mess into a clean canvas for overseeding. My grass is thicker and greener now than it has been in years. That is the result that matters. Just be ready to wrestle with the cord and find a good place to store it. For the price, I think it is worth the hassle.
