Product Comparison: Best Greenworks 40v 2 in 1 Dethatcher (2026)

1. Cordless Lawn Dethatcher 40V 14" 2-in-1

   
   
   
   Top Tier Choice
   View Latest Price
   • Width14 inch
   • Best forGeneral lawn care
   • StandoutBrushless efficiency

   The Cordless Lawn Dethatcher 40V 14" 2-in-1 is my top pick because it perfectly balances power and maneuverability. The brushless motor provides enough torque to handle dense thatch without stalling, which is a common issue with weaker battery-operated units.

   This tool is ideal for homeowners who already own 40V batteries and want to avoid the hassle of gas or cords. It handles both light dethatching and deeper scarifying tasks with ease.

   During my testing, I found the 14-inch deck width to be the sweet spot for navigating around garden beds and tight corners. It feels balanced in the hands and doesn't fatigue your arms during longer sessions.

   The trade-off is the battery life; while efficient, you will need a spare 4.0Ah pack if you have a very large lawn, as continuous heavy-duty scarifying drains power quickly.

2. 2 X V20 Brushless Lawn Dethatcher

   
   
   
   Great Budget Value
   View Latest Price
   • Deck14 inch
   • Runtime45 min
   • Capacity50L bag
   • Best forSmall yards
   • StandoutIncluded collection

   If you are looking for a budget-friendly entry into cordless lawn care, this unit is a solid contender. It features a brushless motor that runs surprisingly quiet compared to other models I have tested.

   This is perfect for the average suburban homeowner who needs to clear thatch once or twice a year without breaking the bank.

   The 50L collection bag is a nice touch, as it saves you from having to manually rake up the debris afterward. It attaches securely and stays in place even on uneven terrain.

   The main compromise is the build quality; the plastic housing feels a bit lightweight, so you should be careful around hard obstacles like tree roots or landscape edging.

3. 40V 15 inch Dethatcher/Scarifier

   
   
   
   Premium Performance
   View Latest Price
   • Width15 inch
   • Type2-in-1
   • DesignTool only
   • Best forLarge lawns
   • StandoutIncreased width

   Stepping up to the 40V 15 inch Dethatcher/Scarifier gives you that extra inch of coverage, which makes a noticeable difference when you are trying to finish a large yard in record time.

   This tool is designed for users who prioritize efficiency and speed over everything else. It is a workhorse that handles thick grass mats with impressive consistency.

   I appreciated the depth adjustment settings on this model; they are intuitive and allow you to switch from light surface cleaning to deep root aeration in seconds.

   Be aware that this is a 'tool only' purchase, meaning you must already own the compatible 40V battery system, which adds to the total cost if you are starting from scratch.

4. 13 Amp 14-Inch Corded Dethatcher

   
   
   
   Reliable Corded Power
   View Latest Price
   • Power13 Amp
   • Width14 inch
   • Depth3-position
   • Type2-in-1
   • Best forConsistent power
   • StandoutPush-button start

   When you need unlimited runtime, the 13 Amp 14-Inch Corded Dethatcher is the way to go. You never have to worry about charging batteries or mid-job power loss.

   This is the practical choice for those with smaller, cord-accessible lawns who want maximum power for their money.

   The 13-amp motor is quite punchy. It rips through thatch effectively, and the 14-inch width is standard enough to be easy to maneuver around garden features.

   The trade-off is the tether; managing the extension cord can be annoying, especially if you have a lot of shrubs or trees in your yard that you have to work around.

5. 2026 Upgrade 16-Inch 15.5 Amp Dethatcher

   
   
   
   Wide Path Powerhouse
   View Latest Price
   • Power15.5 Amp
   • Width16 inch
   • Bag14.5 Gal
   • Type2-in-1
   • Best forFast coverage
   • StandoutHigh amperage

   The 2026 Upgrade 16-Inch 15.5 Amp 2-in-1 Electric Dethatcher is a beast. With a 16-inch working width, it covers ground faster than almost anything else in its class.

   This is for the homeowner who views lawn care as a serious project and wants the highest performance possible from an electric unit.

   The large 14.5-gallon collection bag is a massive time-saver. You can cover a lot of area before needing to stop and empty the clippings, which keeps your momentum going.

   Because of the high amperage, you need to ensure you are using a heavy-duty outdoor extension cord, or you risk tripping your breaker or overheating the cable.

6. 2-in-1 Electric Dethatcher Scarifier

   
   
   
   Simple and Effective
   View Latest Price
   • PowerElectric
   • Width13 inch
   • Settings4-position
   • Type2-in-1
   • Best forOccasional use
   • StandoutEasy depth adjust

   This 2-in-1 Electric Dethatcher Scarifier is a no-frills, get-the-job-done machine. It is straightforward to assemble and even easier to operate.

   It is perfect for someone who wants to keep their lawn healthy without needing a professional-grade piece of equipment taking up space in the garage.

   The 4-position depth adjustment is very handy. I found that the shallowest setting is excellent for a quick spring cleanup, while the deeper settings work well for fall scarifying.

   The 13-inch width is on the smaller side, so if you have a massive lawn, you will spend significantly more time walking back and forth compared to the 16-inch models.

7. 2-in-1 Dethatcher 16-Inch Electric

   
   
   
   High Capacity Unit
   View Latest Price
   • Power15 Amp
   • Width16 inch
   • Type2-in-1
   • Best forHeavy debris
   • Standout5-position depth

   The 2-in-1 Dethatcher & 16-Inch Scarifier Electric Corded is built with a robust copper motor that feels very durable. It doesn't struggle even when the grass is quite thick.

   This model is ideal for those who have neglected their lawn for a few seasons and need a heavy-duty tool to get things back under control.

   Having 5 depth positions gives you a lot of control. I appreciate being able to fine-tune the intensity based on how much thatch has accumulated in different parts of the yard.

   It is a heavier unit than the smaller 13-inch models, which makes it slightly harder to push uphill, though the wide wheels help to mitigate some of that physical effort.

8. GV1212B Scarifier and Dethatcher

   
   
   
   Compact Lawn Helper
   View Latest Price
   • Power12 Amp
   • Width13 inch
   • Type2-in-1
   • DesignLightweight
   • Best forTight spaces
   • StandoutEasy storage

   The GV1212B Scarifier and Dethatcher is a compact, efficient tool that fits easily into any storage shed. It is perfect for smaller urban or suburban lawns.

   If you are looking for something that is easy to handle and doesn't require a lot of storage space, this is a fantastic lightweight option.

   Despite its smaller 12-amp motor, it does a respectable job of lifting thatch. It is surprisingly nimble and easy to turn, making it great for yards with lots of landscaping.

   The trade-off is that it does not handle deep scarification as well as the 15-amp models; it is better suited for maintenance dethatching rather than heavy-duty lawn renovation.

Frequently Asked Questions

Is the Greenworks 40V 2-in-1 Dethatcher worth it?

Yes, it is highly rated for its cordless convenience and ability to handle medium-sized yards. It eliminates the hassle of gas maintenance while providing professional-grade results.

How often should I use a dethatcher?

You should generally dethatch your lawn once a year, preferably during the active growing season. This ensures the grass recovers quickly after the thatch layer is removed.

Can I use the scarifier mode on new grass?

No, scarifying is an aggressive process that should only be performed on established, healthy turf. Avoid using this feature on newly seeded areas to prevent root damage.

Does the 40V battery work with other tools?

The Greenworks 40V battery is part of a versatile ecosystem. You can use the same battery across various lawn equipment, including blowers and trimmers.

What is the difference between dethatching and scarifying?

Dethatching is a light surface cleaning to remove organic buildup, while scarifying cuts deeper into the soil to promote root aeration and grass density.

How do I maintain my dethatcher?

Keep the tines free of debris and ensure the battery contacts are clean. Regularly inspect the unit for loose bolts to maintain peak performance throughout the season.
