This maker covers the field from a basic corded dethatcher to battery machines on two different platforms, and the listings overlap enough to confuse. The real choice is corded or cordless, and then which battery system you buy into.

This guide compares the lineup by motor, path width, included batteries and reel options, and it flags where a bare tool only makes sense if you already own the packs.

Before you buy

6 Criteria to Look For Before Buying a Greenworks Electric Dethatcher

  1. 01

    Bag size and fabric

    Bag capacity decides how often you stop, and thick thatch fills any bag quickly. The Greenworks 40V kit comes with a collection bag, but plan to empty it several times on a quarter acre. Look for a zipper or latch you can open easily. Measure the lawn and note where the nearest outlet is before choosing between corded and cordless. Keep the receipt and photograph the machine on arrival so shipping damage is easy to document.

  2. 02

    Weight and handling

    Weight and handling matter when you lift the machine into a vehicle or roll it over soft ground. Most electric dethatchers fall between 20 and 35 pounds, so check the listing before buying. The Greenworks 13A 14-inch is worth comparing against the Greenworks 40V kit for how it feels to handle. Folding handles and a bag that detaches without tools help. Measure the lawn and note where the nearest outlet is before choosing between corded and cordless.

  3. 03

    Motor rating and circuit

    Corded motors are rated in amps and cordless ones in volts and battery capacity. The Greenworks 40V kit lists 40V brushless. Higher amperage holds rpm in dense thatch, but a 15 amp tool is already at the limit of a 15 amp household circuit, so it must not share the outlet with anything else. Compare rpm only between machines with the same reel type. Walk the lawn first and pick up sticks, stones and toys, because hard objects bend tines.

  4. 04

    Timing and lawn condition

    Dethatch when the grass is actively growing and recovering. Early fall is best for cool-season lawns and late spring for warm-season grass, with soil moist but not soaked. Mow short first, make the first pass at the shallowest depth, then rake and overseed. Even a capable machine like the Greenworks 40V kit will damage a dormant or drought-stressed lawn. Walk the lawn first and pick up sticks, stones and toys, because hard objects bend tines.

  5. 05

    Tine and blade material

    Tine and blade material decide durability. Stainless or spring steel resists rust better than plain carbon steel, and bent tines should be replaced rather than reused. The Greenworks 48V and the Greenworks 40V tool-only both use replaceable tines, so a spare set is cheap insurance. Dull or bent parts tear grass instead of lifting thatch. Plan for a rake and a tarp, since a dethatched lawn produces more debris than people expect.

  6. 06

    Working width and passes

    Working width runs from 14 inches on the Greenworks 13A 14-inch to 15 inches on the Greenworks 40V kit. A wider path means fewer passes, but it needs a stronger motor and a larger bag, and it is harder to steer around beds and trees. Under about a quarter acre, the narrower models are often the better handlers. Measure gate clearance, since the machine body can be wider than the path. Plan for a rake and a tarp, since a dethatched lawn produces more debris than people expect.

Spec sheet decoder

What the numbers on the box really mean

The specs manufacturers lead with, translated into what they tell you about real-world performance.

Working width

The strip of lawn cleared per pass. Wider saves passes but demands a stronger motor and a bigger bag.

Watch forWidths here run 14 to 15 inches.

Reel type

Spring tines lift surface thatch, blades slice into soil for scarifying. Most 2-in-1 machines swap between them.

Watch forConfirm both reels arrive with the Greenworks 40V kit.

RPM

Reel speed in rotations per minute. It affects how aggressively the tines or blades work, though real work depends on torque.

Watch forCompare rpm only between the same reel type, such as the Greenworks 48V and Greenworks 40V tool-only.

Motor amps or volts

Amps describe corded draw; volts and amp-hours describe cordless capacity. Higher numbers hold speed under thatch load.

Watch forThe Greenworks 40V kit lists 40V brushless.

Depth positions

Preset heights that set how deep tines or blades reach. More steps give finer control and fewer scalped patches.

Watch forCheck the range and steps on the Greenworks 40V tool-only.

Methodology

How We Evaluated These Greenworks Electric Dethatchers

Reel versatility

Machines that include both a tine reel and a blade reel scored higher. The Greenworks 48V was checked for the second reel and its swap method. Tool-free changes counted in its favor.

Handling and size

We weighed path width against the likely lawn shape, flagging machines with wide bodies. The Greenworks 10A 14-inch was judged on turning around beds. Lighter machines scored higher for older owners and car transport.

Collection and cleanup

Bag size and ease of emptying decide how smooth a job feels. We noted capacities where published and penalized unclear bag listings. Larger bags earned credit for thick thatch.

Motor and power

We compared stated amps, volts and rpm across the lineup. The Greenworks 40V kit and the Greenworks 40V tool-only were read side by side. Higher ratings counted only when the reel and width could use them.

Value and ownership

Value was judged by tier within the retrieved listings and by what is included. Established brands earned credit for parts availability. Lesser-known brands were scored on stated warranty and owner feedback patterns.

Pricing moves, so treat the order as a snapshot. The cheapest pick here, the Greenworks 13A 14-inch, and the highest, the Greenworks 10A 14-inch, can swap places after a sale.

Corded vs Cordless

Corded machines

Corded dethatchers run without a runtime limit and usually cost less, but you manage a heavy-gauge extension cord and plan your passes around it. In this guide: Greenworks 13A 14-inch and Greenworks 10A 14-inch.

Cordless machines

Cordless machines remove the cord and let you roam, but heavy thatch drains packs quickly, so battery capacity and a spare pack decide the experience. In this guide: Greenworks 40V kit, Greenworks 48V and Greenworks 40V tool-only.

Corded suits lawns near an outlet; cordless suits owners who already have the battery platform.

By Lawn Shape

The same machine can be a great or a poor choice depending on the condition it faces, so match the situation first and the model second.

For Battery Platform Fans Specifically

Look for

Check platform voltage, included batteries and charger, and whether both a tine reel and a blade reel come in the box.

In this comparison

The Greenworks 40V kit fits best on the strength of 40V brushless motor. The Greenworks 40V tool-only is the alternative when greenworks 40V owners with spare batteries.

When to Spend More

Spend more if

You want what the Greenworks 10A 14-inch offers: 10 amp motor and stainless steel tines. That matters when you will use it every season or on a larger area.

Save if

The lawn is modest or the job is occasional. The Greenworks 13A 14-inch gives you 13 amp motor, with the caveat of only three depth steps.

Ownership

Maintenance schedule

FAQ

Frequently Asked Questions

How do I know if I need to dethatch?

Cut a small plug and measure the spongy brown layer between grass and soil. If it is thicker than about half an inch, dethatching helps; thinner than that, leave it. A machine like the Greenworks 48V is overkill for a thin layer.

Do electric dethatchers actually aerate?

Some listings, such as the Greenworks 40V tool-only, are labeled dethatcher and aerator, but the blade reel only slices thin grooves in the surface. It does not remove soil cores. For true compaction relief, use a core aerator separately.

Should I overseed after dethatching?

Yes, and it works best right after scarifying because seed contacts bare soil. Rake up loosened debris with the Greenworks 40V kit's bag, spread seed and keep the area moist for a few weeks.

Is a cordless dethatcher strong enough?

For small to mid-size lawns, yes, if you have enough battery capacity. Heavy thatch drains packs quickly, so plan on a spare. Corded models such as the Greenworks 40V kit have no runtime limit.

When is the best time to dethatch?

Dethatch when the grass is actively growing, early fall for cool-season grass and late spring for warm-season grass. Soil should be moist but not soaked. Avoid dethatching during drought or dormancy.

How long an extension cord can I use?

Use a heavy-gauge outdoor cord, 14 gauge or thicker for long runs, and keep it as short as practical. A thin cord drops voltage and makes the motor stall. Plug the machine into a circuit that is not shared with other heavy loads.
