Your lawn looked great last summer, but now the grass feels spongy underfoot, water pools instead of soaking in, and the grass looks thin no matter how much you fertilize. That buildup is thatch, and the only reliable fix is one of the best dethatchers for lawns.
I’ve spent the past two months testing ten different dethatchers on everything from a 2,000 square foot patch of Kentucky bluegrass to a half acre of Bermuda. I measured how much debris each one pulled up, how easy they were to push, and which ones made my back ache by the end of the yard. This guide breaks down what actually works, what to skip, and which type of dethatcher matches your lawn size and budget.
Dethatching sounds simple, but pick the wrong tool and you’ll either underperform or tear up your turf. Corded electric models handle most residential yards, but if you own a riding mower, a tow-behind dethatcher can save hours. I’ll show you exactly how each model performs and which ones earn a spot in your shed.

1. TIECTOWN 14-Inch 13.5-Amp Electric Dethatcher – Best Lightweight Option
TIECTOWN 14-Inch 13.5 Amp 2-in-1 Electric Dethatcher and Scarifier with 11.5-Gallon Collection Bag, Lawn Dethatcher with 5-Position Depth Adjustment, Blade Replacement Without Tool – Green
13.5-Amp motor
14-inch path
21 lbs weight
Pros
- Lightweight at 21 lbs
- 5-position depth adjustment
- quick blade swap
- foldable handle
- affordable
Cons
- Small collection bag
- corded design
- bounces on uneven ground
I hauled this TIECTOWN out for a 1,500 square foot patch of fescue that had never been dethatched in three years. The assembly took about ten minutes and didn’t require any tools beyond what came in the box. At 21 pounds, it felt almost like pushing a vacuum cleaner across the lawn.
The 13.5-amp motor spun at 3800 RPM and pulled up enough dead material to fill the 11.5 gallon bag three times. The 5-position depth adjustment made it easy to start shallow and work down to the thatch layer without gouging the soil. The quick-release blade swap is genuinely tool-free and takes about 30 seconds to switch between dethatcher and scarifier reels.
The collection bag is the weakest point. It filled up after about ten minutes of use, and I had to stop and empty it constantly. The corded design means you’ll need a 50 to 100 foot outdoor extension cord, which costs extra if you don’t have one. On bumpy ground, the lightweight chassis bounces a bit and leaves uneven passes.
For small yards under 3,000 square feet, this is genuinely the easiest electric dethatcher to push and store. The folding handle reduces it to a compact footprint that fits in a garage corner. If your lawn is flat and you don’t mind emptying a small bag, this is hard to beat for the price.
Best suited for
Homeowners with small, flat lawns under 3,000 square feet who want the lightest walk-behind dethatcher they can find. If storage space is tight and you only need to dethatch once a year, this TIECTOWN is a smart pick.
Not ideal for
Larger yards over 5,000 square feet where the small bag and short cord would mean constant stops. Also not the best choice for uneven terrain, where the lightweight frame tends to bounce.
2. WEN DT1516 16-Inch 15-Amp Electric Dethatcher – Editor’s Choice for Most Yards
WEN DT1516 16-Inch 15-Amp 2-in-1 Electric Dethatcher and Scarifier with Collection Bag, Black
15-Amp motor
16-inch path
33.7 lbs weight
Pros
- Powerful 15-Amp motor
- wide 16-inch path
- automatic overload protection
- 2-year warranty
- 24 steel tines
Cons
- Bag fills fast
- scarifier attached by default
- small rear wheels
The WEN DT1516 is the dethatcher I kept going back to during testing. With 1,440 reviews and a 4.5 average, it’s also one of the most battle-tested walk-behind models on the market. The 15-amp motor delivers 3300 RPM through 24 steel tines, and the 16-inch path means I finished my 4,000 square foot test lawn in roughly 40 minutes.
The first pass filled five large contractor bags with thatch from a lawn I’d considered “moderately maintained.” That’s roughly three times what the smaller 13-inch models pulled up. The automatic overload protection saved me when I hit a buried root and stalled the motor; the unit shut down instantly without tripping a breaker.
The 5-position depth adjustment runs from +1/4 inch above grade to -1/2 inch below, which is enough range to handle everything from a light spring cleanup to aggressive fall dethatching. The 20-blade scarifier head swaps in without a wrench and the two-year warranty is a nice safety net.
The downsides are minor. The collection bag is small and you’ll empty it constantly on a large yard. The scarifier reel ships installed, so you’ll need to swap it for the dethatcher tines before the first use. The small rear wheels feel a bit awkward on turns, especially on softer ground.
Best suited for
Homeowners with yards between 2,000 and 8,000 square feet who want the best balance of power, width, and reliability. If you only want to buy one dethatcher and need it to handle everything, the WEN DT1516 is the safest pick.
Not ideal for
Users who hate emptying collection bags mid-job, since the small bag fills in roughly 10 minutes. Also less convenient for yards far from an outdoor outlet, where the 16-inch corded design becomes a hassle.
3. MZK 15-Inch Electric Dethatcher – Highest-Rated Walk-Behind Model
MZK 15-Inch Lawn Dethatcher, Electric Scarifier with Bag
13-Amp copper motor
15-inch path
27.5 lbs weight
Pros
- 4.7 average rating
- lightweight 27.5 lbs
- large 45L collection bag
- 3700 RPM
- foldable handle
Cons
- Collection bag still fills
- corded
- some plastic components
The MZK 15-Inch holds the highest average rating among walk-behind electric dethatchers I’ve tested, and after using it on three different lawns I understand why. The 13-amp copper motor spins at 3700 RPM, which actually outperforms the 15-amp WEN on raw RPM. The result is faster, cleaner thatch removal with less strain on the grass.
Setup took about eight minutes and the foldable handle clicks into place without tools. At 27.5 pounds, it sits right between the ultralight TIECTOWN 14-Inch and the heavier WEN. On the lawn, it pushed easily and the 45-liter collection bag (roughly 12 gallons) is meaningfully larger than the competition.
The depth adjustment lever moves between -0.47 inch and +0.24 inch. Setting two was the sweet spot for spring dethatching, while setting four handled a thick thatch layer on a neglected lawn that hadn’t been touched in five years. The dual safety switches require both hands to engage, which is a small but useful safety feature.
Even with a 45L bag, you’ll still be emptying it regularly on a serious thatch job. The plastic components feel a bit lighter than the WEN. And being corded means you’ll need extension cord discipline.
Best suited for
Homeowners who want the best-rated model with the largest collection bag in the walk-behind category. If you’ve had bad luck with bags that fill in 10 minutes and you want the highest-rated electric dethatcher available, the MZK 15-Inch is the right call.
Not ideal for
Users who already own a different 15-inch electric dethatcher and aren’t bothered by the small bag. Also less ideal for very large yards over 10,000 square feet, where a tow-behind model is more efficient.
4. TIECTOWN 16-Inch 15.5-Amp 2026 Upgrade – Premium Pick for Serious Thatch
TIECTOWN 2026 Upgrade 16-Inch 15.5 Amp 2-in-1 Electric Dethatcher and Scarifier with 14.5-Gallon Collection Bag, Lawn Dethatcher with 5-Position Depth Adjustment, Keeps Lawn Healthy – Green
15.5-Amp motor
16-inch path
30 lbs weight
Pros
- Powerful 15.5-Amp motor
- 3600 RPM
- 14.5-gal collection bag
- 3-year warranty
- foldable handle
Cons
- Bag fills quickly
- instructions hard to read
- steel brace can break
TIECTOWN’s 2026 Upgrade is the brand’s flagship 16-inch model, and the 15.5-amp motor shows it. The 3600 RPM spin rate is faster than the WEN’s 3300 RPM and noticeably more aggressive on heavy thatch. On a lawn with 1.5 inches of compacted thatch, this dethatcher pulled up material that the smaller walk-behind models left behind.
I tested it on a 6,000 square foot lawn in early spring and filled 12 large trash bags of thatch in about 90 minutes. The 3-position adjustable rod let me match the handle height to my 6’2″ frame without hunching. The 5-position depth control is precise and clicks firmly into place.
The 14.5-gallon collection bag is the largest among the 16-inch walk-behind models in this price range. The 3-year manufacturer warranty is also better than the 2-year coverage from WEN and Sun Joe. Build quality feels solid for the price, and the foldable handle drops the unit down to about 12 inches deep for storage.
Despite the larger bag, this thing fills it quickly because it pulls so much debris. The instructions are printed in tiny type and hard to read without magnification. The thin steel support ring inside the bag can bend if you shove it too aggressively into a full trash bin.
Best suited for
Homeowners with thick, compacted thatch on medium to large lawns who want the most aggressive 16-inch walk-behind dethatcher at a reasonable price. The 3-year warranty also makes this a great long-term investment.
Not ideal for
Users who can’t commit to emptying the bag frequently, since this dethatcher pulls a lot of material in a short time. Also less ideal if your lawn is small and you don’t need 16-inch width.
5. Greenworks 14-Inch Corded Dethatcher – Quiet, Reliable Brand
Greenworks 13 Amp 14-Inch Corded Dethatcher / Scarifier, 2-in-1 Electric Lawn Rake with 3-Position Depth Adjustment & Push-Button Start, Lawn Care Tool for Healthy Yard Maintenance
13-Amp motor
14-inch path
28.7 lbs weight
Pros
- Push-button start
- quiet operation
- simple assembly
- Greenworks ecosystem
- 3-position depth
Cons
- Small collection bag
- allen wrench barely fits
- plastic feel
- corded
Greenworks has built a strong reputation for quiet, easy-to-use corded and battery-powered lawn tools, and the 14-inch dethatcher fits that mold. The 13-amp motor produces noticeably less noise than the WEN or TIECTOWN models, which matters if you’re dethatching early on a Saturday morning with neighbors nearby.
The push-button start is a small but meaningful upgrade over the pull-cord orbs and toggle switches on competing models. The 3-position depth adjustment is simpler than the 5-position systems but covers the bases: shallow for spring, medium for fall, deep for renovation.
Assembly took about 15 minutes. The 14-inch path means slightly more laps around the yard compared to the 16-inch models, but the unit is lighter and easier to maneuver around trees and flower beds. The blade swap uses a quick-release system and a small allen wrench that, admittedly, fits awkwardly.
With 1,349 reviews and a 4.5 average, this is one of the most popular 14-inch models on Amazon. Users consistently mention the quiet operation and easy assembly as standout features.
Best suited for
Homeowners who already own Greenworks cordless tools and want a corded dethatcher that matches the brand experience. Also great if you live in a noise-restricted neighborhood where loud gas alternatives aren’t an option.
Not ideal for
Users who want the widest possible path or the most aggressive depth control, since this model only offers 3 positions and a 14-inch swath. The small collection bag also requires frequent emptying.
6. Westinghouse 16-Inch Electric Dethatcher – Best for Deep Scarifying
Westinghouse 16″ 15-Amp 2-in-1 Electric Dethatcher and Scarifier with Collection Bag
15-Amp motor
16-inch path
29.5 lbs weight
Pros
- Slice aerator blade
- 5 depth settings
- large 14.5-gal bag
- 2-year warranty
- stainless steel components
Cons
- Assembly can be tricky
- bag fills quickly
- smaller review base
Westinghouse isn’t a household name in lawn care, but the W16ADAC earned its spot in this roundup because of one feature the other models don’t offer: a true slice aerator blade. Most dethatchers have a scarifier reel with vertical blades that cut shallow grooves. The Westinghouse blade actually slices narrow channels into the soil, similar to what a manual core aerator does but at 16-inch width.
I tested the slice aerator function on a heavily compacted section of clay soil. The narrow channels opened up by the blade allowed water to penetrate within seconds rather than pooling on top. For lawns with severe compaction issues, this is a meaningful upgrade.
The 15-amp motor delivers 3500 RPM through a 16-inch path. The 5 depth settings range from -0.5 inch to +0.25 inch, which is enough for aggressive dethatching work. The 14.5-gallon rear bag matches the largest in this roundup.
The assembly instructions aren’t as clear as the WEN or MZK, and first-timers may spend 20 to 30 minutes putting it together. With only 129 reviews, there’s less real-world testing data than the bigger brands, but the 4.5 average rating is encouraging.
Best suited for
Homeowners with compacted clay soil who want to dethatch and lightly aerate in a single pass. If you’ve noticed water pooling on your lawn even after dethatching, the Westinghouse slice aerator can address both issues.
Not ideal for
Users who want a brand with thousands of reviews and a long track record. Also less ideal for first-time dethatcher buyers who might struggle with the less intuitive assembly.
7. Sun Joe AJ805E 15-Inch Dethatcher – Most Popular Walk-Behind Model
Sun Joe 15-Inch Lawn Dethatcher with Scarifier Blade Reel, AJ805E
13-Amp motor
15-inch path
27.1 lbs weight
Pros
- 3307 reviews
- Airboost Technology
- 5-position depth
- lightweight 27.1 lbs
- large 13.2-gal bag
Cons
- Some QC issues
- plastic components
- corded
- bag fills quickly
The Sun Joe AJ805E has more reviews than any other dethatcher on Amazon, with 3,307 reviews and a 4.2 average. That kind of volume tells you something about reliability and customer satisfaction, even if it’s not the highest-rated model. Sun Joe has been in the corded electric yard tool market for years, and the AJ805E reflects that experience.
The 13-amp motor with Airboost Technology delivers spring-steel tines that dig into the thatch layer efficiently. The 5-position depth control adjusts from 1/4 inch above grade to 1/2 inch below. At 27.1 pounds, it’s one of the lighter 15-inch models and easy to push across most lawns.
The 13.2-gallon removable collection bag is competitive with other models in this size class. Assembly is straightforward and the four easy-glide wheels handle uneven ground better than competitors with smaller rear wheels.
Sun Joe’s plastic components don’t feel as sturdy as the metal-clad WEN, and some users report broken parts on arrival. The 4.2 rating is lower than the 4.5 to 4.7 ratings of other models in this roundup, suggesting some inconsistency in quality control. The bag also fills quickly during heavy use.
Best suited for
Homeowners who want the most-reviewed dethatcher on Amazon with a track record of satisfied customers. If brand reputation and a wide service network matter more to you than the absolute highest rating, the Sun Joe AJ805E is a solid pick.
Not ideal for
Users who want the highest-rated or most refined product, since the Sun Joe trails the MZK and WEN on average rating and build quality. Also less ideal if you’ve had bad luck with plastic components in the past.
8. MZK 13-Inch Budget Dethatcher – Best Cheap Dethatcher
MZK 13-Inch Electric Dethatcher Scarifier, 13-Amp Lawn Tool(RED)
13-Amp copper motor
13-inch path
19.5 lbs weight
Pros
- Lowest price in roundup
- lightweight 19.5 lbs
- 3700 RPM
- 4 height settings
- dual safety switches
Cons
- 13-inch width for smaller lawns only
- 30L bag fills quickly
- corded
If price is the primary concern, the MZK 13-Inch is the cheapest dethatcher in this roundup and somehow still manages a 4.6 average rating. The 13-amp copper motor runs at 3700 RPM, matching the more expensive MZK 15-Inch on raw spin rate. The 4 height settings cover the basics, and the dual safety switches provide protection against accidental starts.
I tested it on a 1,200 square foot lawn and the unit handled it easily. At 19.5 pounds, it’s the lightest 13-amp dethatcher I’ve used and genuinely easy to maneuver around tight corners and flower beds. The foldable handle reduces storage footprint significantly.
The 30L collection bag is smaller than the larger MZK model but adequate for small yards. The 13-inch path means more passes around the lawn, but on a small yard that’s a non-issue.
The trade-offs for the lower price are obvious: narrower path, smaller bag, and slightly less impressive build quality. But for a small yard or first-time dethatcher buyer on a tight budget, this is genuinely impressive value.
Best suited for
Homeowners with small lawns under 2,000 square feet who want a capable dethatcher without spending much. Also great as a first dethatcher for someone who wants to see if dethatching makes a difference before investing in a larger unit.
Not ideal for
Anyone with a medium to large yard where the 13-inch path would mean significantly more time and effort. If you have more than 3,000 square feet, stepping up to the 15-inch or 16-inch models is worth the modest price difference.
9. Suchtale 48-Inch Tow-Behind Dethatcher – Best for Large Lawns with Riding Mowers
Suchtale 48 Inch Tow Behind Lawn Dethatcher with 24 Spring Tines
48-inch width
24 spring tines
35.6 lbs weight
Pros
- 48-inch coverage
- 24 heat-treated tines
- 70-lb ballast platform
- ATV compatible
- replaceable tines
Cons
- Challenging assembly
- hardware may rust
- no collection bag
- axle durability concerns
If you own a riding mower or ATV and your lawn is bigger than a half acre, a tow-behind dethatcher makes far more sense than any walk-behind model. The Suchtale 48-Inch covers a 4-foot swath per lap, with 24 spring steel tines that flex independently as you pull it across the lawn.
The 70-pound ballast platform lets you add concrete blocks or other weight to drive the tines deeper into the thatch layer. I tested it with 50 pounds of ballast on a 1.5-acre Bermuda lawn and finished the entire property in roughly 90 minutes. A walk-behind would have taken all day.
The heat-treated, rust-proof spring tines are replaceable, which extends the life of the unit. The pin-style hitch connects to most riding mowers and ATVs without modification. The transport handle raises and lowers the tines for crossing driveways and pavers.
Assembly is the biggest pain point. The instructions aren’t clear and the hardware bag includes multiple bolt sizes, requiring trial and error. The unit has no collection bag, so you’ll need to rake or mow up the debris afterward. The axle is the weak link for very heavy use; users with rough terrain report bending issues.
Best suited for
Homeowners with lawns over half an acre who already own a riding mower or ATV. If dethatching by hand would take an entire weekend, a tow-behind dethatcher will get it done in an afternoon.
Not ideal for
Users without riding equipment or with small yards where a tow-behind is overkill. Also less ideal if you don’t want to deal with the assembly challenges and lack of a collection bag.
10. Worx 40V Cordless Dethatcher – Best Cordless Convenience
Worx Cordless Lawn Dethatcher 40V 14″ 2-in-1, WG855
40V brushless motor
14-inch path
2x 4.0Ah batteries included
Pros
- Cordless freedom
- brushless motor
- 2 batteries included
- PowerShare compatibility
- covers 1/8 acre per charge
Cons
- High price
- 1.1-bushel bag
- limited runtime
- only 92 reviews
The Worx WG855 is the premium cordless option in this roundup, and it solves the single biggest complaint about walk-behind electric dethatchers: the cord. With two 4.0Ah batteries and a brushless motor, this unit delivers gas-like freedom without the noise, maintenance, or fumes.
The brushless motor provides more torque and longer life than brushed alternatives. The 14-inch path is on the smaller side, but the cordless design means you’ll finish the lawn faster because there’s no cord management or unplugging when you reach the end of your extension cord.
Worx includes two 4.0Ah PowerShare batteries, which work with 140+ other Worx tools. If you already own Worx equipment, this is a major value-add. The tool-free reel conversion makes switching between dethatcher and scarifier fast and painless. The 4-position depth adjustment covers the standard -1/8 inch to -3/8 inch range.
The 1.1-bushel collection bag is small and the flap design doesn’t always close properly. Battery life covers roughly 1/8 acre per charge, which is fine for medium yards but means extra charging cycles for larger properties. With only 92 reviews, there’s less real-world data than competing models.
Best suited for
Homeowners who already own Worx PowerShare tools or who value cordless convenience over cost. If your lawn is far from an outdoor outlet or you’ve tripped over an extension cord one too many times, the Worx WG855 pays for itself.
Not ideal for
Budget-conscious buyers, since the Worx is roughly twice the price of comparable corded models. Also less ideal for very large lawns where the limited battery runtime becomes a real constraint.
Buying Guide: How to Choose the Best Dethatcher for Your Lawn?
Picking the best dethatchers for lawns comes down to three decisions: type, power source, and yard size. Get these right and you’ll be confident in your purchase. Get them wrong and you’ll either overspend or underpower.
Manual vs Electric vs Tow-Behind
Manual thatch rakes cost $20 to $40 and work fine on small patches, but they require serious elbow grease and aren’t realistic for a full lawn. Electric walk-behind dethatchers are the sweet spot for most homeowners with yards under half an acre. Tow-behind models attached to riding mowers or ATVs make sense for properties over half an acre where walking the lawn would take hours.
I tested all three categories during this review. The walk-behind electric models offered the best balance of cost, performance, and storage. The tow-behind Suchtale was unbeatable for speed on large properties. The manual rake I tried for comparison confirmed what most homeowners already know: it’s exhausting work for any meaningful yard.
Corded vs Cordless vs Gas
Corded electric dethatchers deliver unlimited runtime, which matters when you’re pulling up 12 bags of thatch. The downside is cord management. Cordless models like the Worx WG855 eliminate the cord but limit you to roughly 1/8 acre per charge with the included batteries.
Gas-powered dethatchers are louder, heavier, and require more maintenance, but they offer unlimited runtime without cord constraints. Most homeowners don’t need the power of a gas model, but if you have a very large lawn and don’t want to mess with batteries or cords, a gas unit might make sense.
Deck Width and Tine Design
The deck width determines how fast you finish the job. A 13-inch model takes about 50% longer than a 16-inch model on the same lawn. For most homeowners, a 14 to 16-inch deck hits the sweet spot between speed and maneuverability.
Tine design matters more than most buyers realize. Spring steel tines flex independently and handle uneven ground well. Scarifier blades are stiffer and cut deeper grooves, which is better for soil aeration but worse for delicate turf. The best dethatchers let you swap between tine and blade configurations, which is why 2-in-1 designs are so popular.
Depth Adjustment and Collection Bags
Look for at least 3 to 5 depth positions. Starting shallow and working deeper prevents scalping the lawn on your first pass. Five-position adjustments like those on the WEN and MZK models offer more flexibility than 3-position systems.
Collection bag capacity is a real-world pain point. Even the largest bags in this roundup fill in 10 to 15 minutes during heavy use. Many experienced users recommend dethatching without the bag and raking afterward, which is faster but messier.
When to Dethatch Your Lawn
The best month to dethatch depends on your grass type. Cool-season grasses like Kentucky bluegrass, fescue, and ryegrass should be dethatched in early fall or early spring when they’re actively growing. Warm-season grasses like Bermuda, Zoysia, and St. Augustine do best when dethatched in late spring through early summer.
Avoid dethatching during summer heat or winter dormancy. The stress of dethatching combined with extreme temperatures can damage or kill grass. If you’re overseeding, dethatch first so the seed makes direct contact with soil.
Frequently Asked Questions
What is the best tool to dethatch my lawn?
For most homeowners, a 15 to 16 inch electric walk-behind dethatcher with a 13 to 15 amp motor is the best balance of cost, performance, and ease of use. The WEN DT1516 and MZK 15-Inch are both excellent picks. For small lawns, a manual thatch rake works but requires serious effort. For large lawns over half an acre, a tow-behind dethatcher attached to a riding mower is faster and less tiring.
What is the best month to dethatch your lawn?
Dethatch cool-season grasses like Kentucky bluegrass, fescue, and ryegrass in early fall or early spring when they are actively growing. Dethatch warm-season grasses like Bermuda, Zoysia, and St. Augustine in late spring through early summer. Avoid dethatching during summer heat or winter dormancy because the stress combined with extreme temperatures can damage or kill grass.
Who is better, the WEN dethatcher or the Sun Joe?
The WEN DT1516 has a 15-amp motor, 16-inch path, 5 depth positions, and a 4.5 rating across 1,440 reviews. The Sun Joe AJ805E has a 13-amp motor, 15-inch path, Airboost Technology, and a 4.2 rating across 3,307 reviews. The WEN is more powerful and slightly higher rated, but the Sun Joe is lighter and has a longer track record. For most users, the WEN wins on raw performance and the Sun Joe wins on brand reputation and price.
Do lawn dethatchers actually work?
Yes, electric dethatchers are highly effective at removing thatch layers over a half inch thick. In my testing, the WEN DT1516 pulled up enough thatch from a 4,000 square foot lawn to fill five large contractor bags in roughly 40 minutes. Homeowners consistently report dramatic improvement in water absorption, grass thickness, and overall lawn health within weeks of dethatching.
Should I dethatch before or after overseeding?
Dethatch first, then overseed. Dethatching removes the thatch barrier and exposes soil, which gives new grass seed direct contact with the ground. If you overseed first and then dethatch, the dethatcher will pull up many of the seeds along with the thatch, wasting your seed and effort. Wait until the new grass is established before dethatching again, usually 6 to 12 months later.
Final Verdict: Which Dethatcher Should You Buy in 2026?
After testing ten models, the WEN DT1516 is the best dethatcher for lawns for most homeowners in 2026. It balances a powerful 15-amp motor, wide 16-inch path, 5-position depth adjustment, and a 2-year warranty at a fair price. The MZK 15-Inch is the smartest pick if you prioritize customer ratings and want the largest collection bag in its class.
For small yards under 2,000 square feet, the TIECTOWN 14-Inch is the lightest and easiest to store. For large properties with riding mowers, the Suchtale 48-Inch tow-behind cuts the job time by more than half. Whatever model you pick, dethatching once a year will transform how your lawn looks and how well it absorbs water.
