Amazon Prime Day string trimmer deals are back for 2026, and our team has been tracking price drops across every major brand since early May. We watched EGO, WORX, Greenworks, Craftsman, BLACK+DECKER, and Husqvarna trimmers fluctuate weekly to figure out which models are actually worth buying when the sale goes live.
String trimmers see some of the deepest discounts of any outdoor power tool during Prime Day. Last year we saw cordless kits drop 25 to 35 percent, and we expect similar or better markdowns this time around. The tricky part is knowing which deals are genuinely good versus which ones just look good on a flashing banner.
That is exactly why we built this guide. We tested seven trimmers across different yard sizes, power types, and budgets to help you cut through the noise. Whether you need a lightweight cordless model for a small suburban lot or a gas-powered beast for thick brush, we have a pick that should hit a sweet deal price. If you want a broader look at the cordless category beyond just Prime Day, check our complete battery string trimmer guide for year-round recommendations.

56V Battery
16-inch Cutting Width
POWERLOAD + LINE IQ
Carbon Fiber Shaft
Up to 60 Min Runtime
I spent three weeks using the EGO Power+ ST1623T on my half-acre property, and it completely changed my expectations for what a cordless string trimmer can do. The LINE IQ technology senses when the line needs feeding and does it automatically. No bumping, no stopping, no wasted line.
The POWERLOAD feature is the real standout. You feed the line through the head, push a button, and it winds itself. Anyone who has wrestled with manual spool reloading will appreciate how much frustration this eliminates. The 16-inch cutting swath made quick work of my fence line and along the driveway.
Battery life is where this trimmer separates itself from cheaper options. The included 4.0Ah battery gave me a genuine 55 to 60 minutes of run time on a single charge. That was enough to trim my entire yard with power to spare. The digital two-speed selector lets you dial back to save battery for lighter work.
At $298.98 currently (down from $359), this is already discounted 17 percent. During Prime Day, I expect it to drop closer to $249 or even lower. EGO products sold out fast during the last sale event, so this is one to add to your cart early. If you already own EGO 56V tools, the battery is interchangeable across the entire lineup.
The EGO 56V ARC Lithium battery works with every tool in the EGO Power+ lineup. That includes their mowers, blowers, chainsaws, and hedge trimmers. If you already own an EGO mower, you could buy this as a bare tool and save significantly. The battery alone retails for around $150, so owning multiple EGO tools brings the per-tool cost down fast.
If you have a medium to large yard and want the most advanced cordless trimmer available, the EGO ST1623T is absolutely worth watching. The combination of LINE IQ, POWERLOAD, and a carbon fiber shaft is unmatched at this price point. The five-year tool warranty and three-year battery warranty add peace of mind that cheaper brands cannot match.
20V Battery
12-inch Cutting Width
2-in-1 Trimmer and Edger
Includes 2 Batteries
PowerShare Compatible
The WORX WG163 is the trimmer I recommend most often to friends with small to medium suburban yards. At $89.99 currently (marked down from $119.99), it already offers solid value. On Prime Day, I expect it to drop to around $69 to $75, which would make it an absolute steal.
What makes this trimmer special is the included package. You get the trimmer, two 20V batteries, a charger, and a spacer guard all in one box. The two batteries mean you can keep one charging while you use the other. In practice, each battery gives me about 15 to 20 minutes of trimming time.
The Command Feed system is a push-button line advance that works well. Instead of bumping the head on the ground, you press a button on the handle and line feeds out. The 90-degree tilting head is surprisingly useful for maintaining slopes and getting under low shrubs.
The WORX PowerShare battery system is one of the biggest selling points. The 20V batteries work with over 140 WORX tools, including their drills, saws, and blowers. If you already own WORX tools, you effectively get extra batteries for free with this kit.
The WG163 converts to an edger in about five seconds. You rotate the head and lower the guide wheels. It does a respectable job along sidewalks and driveways. It will not replace a dedicated lawn edger for heavy-duty work, but for weekly maintenance it is more than adequate.
This is the ideal pick for anyone with a yard under a quarter acre who wants a cordless trimmer without spending over $100. The two-battery setup and edger conversion make it versatile enough for most suburban homeowners. If you are already in the WORX ecosystem, this deal is a no-brainer.
Corded Electric
14-inch Cutting Width
6.5-Amp Motor
Auto Feed Spool
2-in-1 Edger
If you want the cheapest reliable string trimmer on Prime Day, the BLACK+DECKER BESTA510 is your pick. At $59 it is already the lowest-priced trimmer on our list, and Prime Day could push it under $45. For anyone with a small yard and an outdoor outlet, this is hard to beat.
The 6.5-amp motor is surprisingly powerful for a corded trimmer. It cuts through standard grass and light weeds without bogging down. The POWERDRIVE Transmission helps deliver torque efficiently, which means the motor does not strain under normal conditions. I tested it along 200 feet of fence line and it maintained consistent power the entire time.
The auto feed spool works automatically as you trim. There is no bumping required, which is nice. The downside is that it can feed too aggressively sometimes, wasting line. The cord retention system is a thoughtful touch that prevents your extension cord from disconnecting mid-trim.
The trade-off with any corded trimmer is the cord itself. You need a heavy-duty outdoor extension cord, which adds to the total cost if you do not already own one. But the upside is unlimited run time. No batteries to charge, no fuel to mix, just plug in and go.
Corded trimmers give you unlimited runtime and consistent power at a fraction of the cost of battery models. The trade-off is mobility. If your yard is within 100 feet of an outdoor outlet, corded is the smart financial choice. For larger properties, a cordless model will save you significant hassle.
This trimmer shines for small townhouse yards, tight suburban lots, and anyone who already owns an extension cord. It is the type of tool you buy once and use for years without thinking about battery degradation. At the expected Prime Day price, it is one of the best value purchases you can make.
20V Battery
13-inch Cutting Width
2 Speed Settings
Auto Line Advance
Telescoping Pole
The CRAFTSMAN V20 CMCST900D1 sits in the sweet spot between budget and mid-range cordless trimmers. At $99 (down from $119), it is priced right for what you get. Prime Day should bring it closer to $79, making it a strong contender for anyone already invested in the CRAFTSMAN V20 battery system.
I tested this trimmer over two weekends on a quarter-acre lot. The two-speed selector is genuinely useful. Low speed conserves battery for light grass along walkways, while high speed powers through thicker patches near the property line. The automatic line advance fed smoothly without any bumping or manual intervention.
The telescoping pole adjusts to your height, which sounds minor but makes a real difference in comfort over longer trimming sessions. At 6.3 pounds, it is light enough for most adults to use one-handed for short stretches. The VERSATRACK compatibility means you can hang it on CRAFTSMAN's wall storage system.
Battery life is the main limitation. The included 2.0Ah battery gives you 25 to 40 minutes depending on which speed you use and how thick the grass is. For a quarter-acre yard, that is usually enough. For larger properties, you will want a spare battery or a higher-capacity pack.
The CRAFTSMAN V20 system includes over 100 tools ranging from drills to nailers to circular saws. The 2.0Ah battery included with this trimmer works with all of them. If you already own V20 tools, you can buy this as a kit and effectively get a spare battery for your other equipment. The cross-compatibility is where the real savings live.
Both trimmers target the same buyer, but they take different approaches. The WORX includes two batteries while CRAFTSMAN includes one. The CRAFTSMAN offers two speed settings and a wider 13-inch cut path versus WORX's 12-inch. If you already own CRAFTSMAN tools, the V20 is the logical choice. If you are starting fresh, the WORX two-battery package offers better out-of-box value.
40V Battery
12-inch Trimmer + 390 CFM Blower
Auto Feed
Universal 40V Power Hub
67dB Quiet Operation
The Greenworks 40V Combo Kit is the deal I am most excited about this Prime Day. You get a string trimmer and a 390 CFM leaf blower together for $129.99, down from $189.99. That is already a 32 percent discount. On Prime Day, this bundle could hit $99, which would be one of the best outdoor tool deals of the event.
I used both tools together for a full month. The trimmer handles standard suburban yard work without issues. The 12-inch cutting width is narrower than the EGO or Husqvarna models, but for a small to medium yard it is perfectly adequate. The auto-feed system works most of the time, though it occasionally hesitates.
The leaf blower is the surprise value-add. At 390 CFM and 110 MPH, it has enough power for driveway cleanup, deck clearing, and light leaf duty. It will not replace a dedicated leaf blower for large yards, but for everyday cleanup it gets the job done. The shared 40V battery is what makes this kit special.
The Greenworks 40V Power Hub is compatible with over eight tools. That includes pole saws, hedge trimmers, chainsaws, and pressure washers. One battery runs all of them. For someone building a cordless tool collection, this combo kit is the ideal entry point.
The included 2.0Ah battery gives you roughly 20 to 30 minutes per tool. For the trimmer, that covers most small to medium yards. For the blower, it is enough for typical driveway and deck cleanup. If you need longer runtime, Greenworks sells 4.0Ah batteries separately, and they are worth grabbing during Prime Day bundle discounts.
Buying the trimmer and blower separately would cost significantly more than this combo kit. The math only works in favor of the bundle. If you need both tools and want to enter the Greenworks 40V ecosystem, this is the most cost-effective path. Just make sure to grab it early on Prime Day because combo kits tend to sell out first.
40V Battery
16-inch Cutting Width
Power Boost Mode
Dual-Direction Head
Active Cooling System
Husqvarna is best known for professional-grade gas equipment, but the 320iL proves they can build a serious battery trimmer too. At $269.99 (down from $319.99), it sits in the premium tier. Prime Day could bring it under $230, which would make it competitive with the EGO on a dollar-per-feature basis.
The power boost mode is the standout feature. Press a button and you get 20 percent more cutting power for heavy weeds and thick grass. I engaged it while clearing an overgrown drainage ditch, and the difference was immediately noticeable. The trimmer powered through stalks that would have stalled lesser models.
The dual-direction trimmer head lets you choose which way the line spins. This matters more than you might think. Clockwise rotation throws debris away from you, which is ideal for right-handed trimming along fences. Counter-clockwise is better for edging along walls. Having both options in one tool is a thoughtful design choice.
The active cooling system keeps the battery and motor at optimal temperature during extended use. This extends battery life and prevents the power drop-off that plagues cheaper cordless trimmers. The LED indicator tells you the battery and power mode status at a glance.
The battery included with the 320iL works across Husqvarna's entire 40V lineup. That includes their chainsaws, blowers, hedge trimmers, and pole saws. Husqvarna also owns the Poulan Pro and Weed Eater brands, and some batteries cross over. If you already own Husqvarna battery tools, check compatibility before buying the kit version.
Both are premium 16-inch cordless trimmers, but they take different approaches. The EGO wins on technology with LINE IQ and POWERLOAD. The Husqvarna wins on cutting control with the dual-direction head and power boost mode. If you value convenience features, get the EGO. If you prioritize raw cutting control and versatility, the Husqvarna is the stronger pick.
Gas Powered 22cc 2-Cycle
17-inch Cutting Width
SmartStart System
Straight Shaft
Multi-Tool Compatible
The Husqvarna 122LK is the only gas trimmer on our list, and it earns its spot for good reason. At $226.48, it delivers the kind of raw cutting power that battery trimmers still struggle to match. If you have thick brush, tough weeds, or a large property, this is the Prime Day deal to watch.
SmartStart is Husqvarna's engineered starting system that reduces resistance in the starter cord by about 40 percent. In testing, I got it running on the second pull every time. Anyone who has fought with a stubborn gas trimmer will appreciate how much easier this makes the experience.
The 17-inch cutting swath is the widest on our list. That means fewer passes to cover the same area. The straight shaft design lets you reach under bushes, decks, and low branches that curved shaft trimmers cannot access. The T25 trimmer head is easy to restring and holds up well under heavy use.
This trimmer is also multi-tool compatible. Husqvarna's attachments click on and off quickly, turning the 122LK into an edger, pole saw, brush cutter, or tiller. That versatility adds significant value, especially if you maintain a larger property. It is like buying five tools for the price of one power head.
Gas trimmers still win in three scenarios. First, when you need to clear thick brush or woody weeds that stall battery trimmers. Second, when your property is large enough that battery runtime becomes a limiting factor. Third, when you want multi-tool attachment capability for maximum versatility. For everything else, battery trimmers have caught up.
The 122LK runs on a 50:1 gas-to-oil mixture. You mix 2.6 ounces of 2-stroke oil with one gallon of gas. Husqvarna sells pre-mixed fuel that extends engine life and eliminates mixing. Basic maintenance includes cleaning the air filter periodically and replacing the spark plug once per season. The fuel tank holds enough for 45 to 60 minutes of continuous use.
Choosing the right string trimmer during Prime Day comes down to understanding your yard, your budget, and which battery ecosystem you want to commit to. Here is how to think through the decision.
Battery-powered trimmers are the best choice for most homeowners. They start instantly, produce no emissions, and require minimal maintenance. The trade-off is runtime and raw power. Premium battery trimmers like the EGO and Husqvarna 320iL close the power gap significantly, but they cost more.
Gas trimmers still rule for heavy-duty work. If you have acres of property, thick brush, or need multi-tool versatility, gas is the way to go. The Husqvarna 122LK is lightweight for a gas model and starts easily thanks to SmartStart. You will deal with noise, vibration, and fuel mixing in exchange for unlimited runtime.
Corded electric trimmers are the budget champion. They offer unlimited runtime and consistent power at the lowest price. The BLACK+DECKER BESTA510 proves you can get reliable trimming performance for under $60. The limitation is your proximity to an outlet and managing the extension cord.
This is where Prime Day deals get interesting. Every battery-powered brand uses a proprietary battery system. WORX PowerShare batteries work across 140+ tools. CRAFTSMAN V20 covers 100+ tools. Greenworks 40V runs 8+ tools. EGO 56V powers a full outdoor lineup. Husqvarna 40V spans their professional tools.
The smart Prime Day strategy is to pick a battery ecosystem and stick with it. Once you own a battery and charger, you can buy bare tools for much less. Many Prime Day deals will offer bundle pricing on kits that include batteries. If you plan to buy a battery-powered lawn mower, a cordless hedge trimmer, or a leaf blower in the future, choose your trimmer brand accordingly.
On Prime Day, you will see two types of deals. Kits include the tool, battery, and charger. Bare tools include only the trimmer body. Kits are better for first-time buyers who need everything. Bare tools are dramatically cheaper but only make sense if you already own a compatible battery.
As a rule of thumb, if the kit price is less than the bare tool plus separate battery and charger costs, buy the kit. Prime Day often pushes kit prices low enough that they beat bare tool value even for existing owners who want a spare battery.
Cutting width determines how much grass you cut per pass. Trimmers range from 12 to 17 inches. Wider is faster but heavier. Voltage correlates with power. Higher voltage (40V, 56V) means more cutting torque. Line diameter affects durability. Standard line is .065 inch for light duty and .095 inch for heavy work. Weight matters for comfort. Anything under 7 pounds is easy to handle for extended periods.
Based on previous Prime Day data, certain models sell out within hours. The EGO Power+ trimmers are consistently among the first to go. WORX and Greenworks combo kits also disappear fast because they offer the best perceived value. Gas trimmers like the Husqvarna 122LK tend to last longer simply because fewer buyers are shopping for gas models.
My recommendation is to fill your cart before Prime Day begins. Amazon sometimes runs early lightning deals on outdoor tools. If you see a price you like, grab it. Waiting for a potentially deeper discount later in the event can backfire if the item goes out of stock.
The WORX WG163 offers the best value for most homeowners. It includes two batteries, converts to an edger, and typically sells for under $90. On Prime Day it drops even further. For premium value, the EGO Power+ ST1623T offers advanced features like LINE IQ and POWERLOAD that justify the higher price for larger properties.
Yes, Amazon Prime Day 2026 is confirmed for July. The event typically runs for 48 hours though Amazon has been extending deals before and after the main event. Early Prime Day deals on outdoor tools like string trimmers usually begin appearing in mid to late June.
Yes, .105-inch line is thicker and more durable than .095-inch line. It breaks less frequently in heavy brush and lasts longer between refills. However, .105 line requires more power to spin and is overkill for light residential trimming. Most homeowners are better served by .080 or .095 line. Use .105 only if you have a powerful gas or high-voltage battery trimmer and regularly cut thick weeds.
Husqvarna makes the best gas-powered string trimmers for homeowners. The Husqvarna 122LK featured in this guide offers SmartStart technology, a 17-inch cutting width, and multi-tool compatibility. Echo and Stihl also produce excellent professional-grade gas trimmers, but Husqvarna provides the best balance of power, reliability, and value for residential users.
Buy a kit if you do not already own a compatible battery and charger. Kits include everything you need to start trimming immediately and are deeply discounted on Prime Day. Buy a bare tool only if you already own batteries from the same brand ecosystem. Compare the kit price against the bare tool plus separate battery cost to determine which offers better value.
Prime Day remains the best time of year to buy a string trimmer. The seven models we tested cover every power type, budget, and yard size. For most homeowners, the EGO Power+ ST1623T delivers the best overall experience with its smart features and long battery life. The WORX WG163 wins on value with two included batteries and edger conversion. And the BLACK+DECKER BESTA510 is unbeatable for budget buyers with a small yard.
My advice is to decide which battery ecosystem fits your long-term tool plans, set a price target based on the current prices in our comparison table, and act fast when Prime Day goes live. These deals sell out quickly, especially on popular cordless kits. Bookmark this page and check back as we update prices when the sale officially begins.
