Category Overview & Market Context

What This Category Is

String trimmers — also called weed whackers, weed eaters, or line trimmers — are handheld power tools designed to cut grass and weeds in areas a lawn mower cannot reach. They use a rapidly spinning nylon line to slice through vegetation along fence lines, around trees, beside walkways, and in tight corners. Most string trimmers also convert to edgers for creating clean borders along driveways and garden beds.

String trimmers are available in three main power configurations: battery-powered (cordless), gas-powered, and corded electric. This review covers all three types, with separate segment recommendations for battery/cordless models, gas models, and budget-friendly options for smaller yards.

State of the Market

The string trimmer market has shifted decisively toward battery power. Advances in lithium-ion battery technology — particularly in the 40V-to-60V range — have brought cordless models to near-parity with gas on cutting performance, while offering push-button starting, minimal maintenance, and quiet operation. Gas string trimmers remain relevant for large properties and professional use where unlimited runtime matters, but experts now broadly agree that most homeowners will be better served by a battery-powered model.

Battery ecosystem compatibility has become a significant purchasing factor. Brands like EGO, Ryobi, DeWalt, Milwaukee, and Makita each offer broad lineups of outdoor power equipment that share batteries, allowing homeowners to build a coordinated tool collection with interchangeable power packs.

Who This Is For / Not For

This review is for homeowners shopping for a string trimmer to maintain a residential property. It covers battery-powered, gas-powered, and budget options across a range of yard sizes and trimming demands. It is not intended for commercial landscaping professionals, though some recommended models are capable of professional-grade work.

If you maintain a large property with heavy weed growth or need unlimited runtime for extended trimming sessions, see our Best Gas String Trimmer segment. If you have a small yard and want the lightest, most affordable option, see our Best Budget String Trimmer segment.

How This Review Was Produced

This review is based on expert consensus rather than a single reviewer’s opinion.

We analyze and synthesize recommendations from multiple independent expert review sources that meet our editorial quality and transparency standards. We document where experts agree, where they differ, and why. No single source determines our recommendations.

We do not conduct original product testing. Instead, we rely on experts who do — such as publications that perform hands-on testing, lab measurements, or clearly documented evaluation methodologies.

Manufacturers do not influence our recommendations. Advertising, affiliate relationships, or commercial considerations do not affect which products are included, how they are ranked, or how they are described.

When helpful, we also consult additional secondary review outlets to understand how broader expert opinion aligns — or conflicts — with the primary consensus. These secondary sources do not determine winners but may provide context or confirmation.

Why It’s a Top Pick

The EGO Power+ platform dominates expert recommendations for battery-powered string trimmers more convincingly than any other product in this category. Wirecutter names the ST1511T its Top Pick, and closely related EGO models earn top honors from Bob Vila (Best Overall), HGTV (Best Overall), Better Homes & Gardens (Best Overall), and TechGearLab (Best Overall for the Line IQ variant, the ST1623T). Consumer Reports rates the EGO ST1502SA at 87 out of 100, and Pro Tool Reviews selects the ST1623T as its Best Homeowner pick.

EGO’s Powerload technology is the feature experts highlight most consistently. Rather than manually winding trimmer line onto a spool — a process most sources describe as one of the most frustrating aspects of string trimmer ownership — you simply feed a pre-cut length of line into the head and press a button to wind it automatically. Wirecutter, TechGearLab, Pro Tool Reviews, and Family Handyman all single out this feature as a meaningful usability advantage.

The ST1511T specifically adds a telescoping aluminum shaft that adjusts to fit users of different heights, a feature Wirecutter identifies as the key differentiator over the otherwise similar ST1521S (which uses a fixed split shaft). All EGO 56V string trimmers share the same battery platform, so buyers already invested in EGO outdoor power equipment can use existing batteries interchangeably.

A note on EGO model variants: EGO sells several string trimmers in the ST15xx and ST16xx families that share the same 56V motor and Powerload technology. The ST1521S uses a fixed carbon fiber split shaft rather than a telescoping aluminum one. The ST1623T adds Line IQ — a sensor that automatically detects when line is worn and releases more — along with a 16-inch cutting swath and carbon fiber telescoping shaft. The ST1502SA uses a Rapid Reload head rather than Powerload. All are strong performers, and the best choice depends on whether you prioritize shaft adjustability (ST1511T), automatic line feeding (ST1623T), or a lower entry point (ST1502SA).

What Experts Like

  • Powerload technology eliminates the frustration of manual line winding — feed the line in and press a button
  • Strong cutting performance that experts consistently compare to gas-powered models, with the convenience of push-button starting
  • Telescoping shaft adjusts to fit users of different heights without tools
  • 56V ARC Lithium battery platform is compatible with all EGO outdoor power equipment, with up to 45 minutes of runtime per charge

Trade-Offs to Consider

  • Carries a price premium over entry-level battery trimmers, though experts broadly consider it justified by the performance and convenience features
  • Runtime is limited to approximately 30-45 minutes per charge, which may require a second battery for larger properties
  • Heavier than some lightweight 20V models, though well-balanced for its size

Runners-Up

While the EGO ST1511T earns the broadest consensus, several other battery-powered trimmers received strong expert support and may be a better fit depending on your priorities.

  • Makita XRU15PT — Consumer Reports’ top-rated battery string trimmer (90 out of 100, tied with Milwaukee), the Makita earns praise for its three-speed Automatic Torque Drive system and reverse rotation function that clears tangled grass without stopping. Better Homes & Gardens names it Best for Large Yards. Its dual-battery 36V (18V x2) system offers extended runtime but adds complexity and a higher price point compared to the EGO.
  • Ryobi 40V HP Brushless Carbon Fiber String Trimmer — Pro Tool Reviews’ top homeowner pick in its head-to-head shootout (90 points), the Ryobi also earns Best Overall from Family Handyman and The Spruce. Its Expand-It attachment system is a standout feature, allowing the power head to accept edger, pole saw, hedge trimmer, and other attachments. It did not match the EGO’s cross-source breadth, and its 40V platform delivers less cutting power than 56V competitors in thick brush.
  • Milwaukee 3016-21ST M18 FUEL — Tied with the Makita for Consumer Reports’ top battery rating (90 out of 100), the Milwaukee stands out for its QUIK-LOK attachment system and powerful brushless motor. It is part of the expansive M18 battery platform. However, it is the heaviest battery model tested and fewer sources feature it as prominently as the other runners-up.

Best Gas String Trimmer: Echo SRM-2620

BEST GAS STRING TRIMMER

Echo SRM-2620

Echo SRM-2620

The top-rated gas string trimmer in Consumer Reports’ testing, earning praise for its cutting power, clean edging, and reliable starting. For homeowners with large properties or heavy weed growth where unlimited runtime matters, gas remains the practical choice — and the Echo SRM-2620 leads the field.

Note: As of Jan. 1, 2024, California law (AB 1346) prohibits the sale of new gas-powered string trimmers in the state. Existing gas equipment may still be used, but new gas models cannot be purchased from California retailers. Buyers in California should consider the battery-powered options in our Best Battery / Cordless segment. Similar restrictions may apply in other states and municipalities.

Why It’s a Top Pick

Consumer Reports gives the Echo SRM-2620 its highest gas string trimmer score (83 out of 100), with top marks for trimming, edging, and clearing tall grass and weeds. Popular Mechanics names Echo’s SRM-2620 its Most Powerful Gas pick. The closely related SRM-2620T (X-Series) — a pro-grade variant with a high-torque 2:1 gear reduction — is Pro Tool Reviews’ Best Pro Gas pick, HGTV’s Best Gas pick, and The Spruce’s Best Overall Gas pick (as well as one of our runners-up).

Echo built its reputation on gas-powered outdoor equipment, and the SRM-2620 reflects that heritage. Its 25.4cc professional-grade engine starts reliably in all conditions, and its Speed-Feed cutting head reloads in seconds without requiring disassembly. Consumer Reports’ member surveys give Echo gas straight-shaft trimmers above-average reliability and excellent owner satisfaction.

Gas trimmers remain the practical choice when battery runtime is a limiting factor. As Consumer Reports notes, the best battery trimmers run for approximately 30 minutes per charge, and that time drops significantly in thick brush. For homeowners maintaining acreage or regularly clearing dense overgrowth, the gas model’s ability to refuel and keep cutting is a meaningful advantage.

What Experts Like

  • Top-rated gas trimmer in Consumer Reports’ testing, with strong marks across all performance categories
  • Speed-Feed cutting head reloads trimmer line quickly without disassembly
  • Large fuel tank provides extended runtime between refueling stops
  • Excellent reliability and owner satisfaction in Consumer Reports’ member surveys

Trade-Offs to Consider

  • Requires 2-cycle fuel mixing and regular engine maintenance (spark plugs, air filters, winterizing)
  • Louder than battery-powered alternatives — Consumer Reports notes all gas trimmers require hearing protection
  • Heavier than most battery models and produces exhaust fumes
  • Pull-start operation, though Echo’s i-30 starting system reduces the effort required

Runners-Up

  • Echo SRM-2620T (X-Series) — The pro-grade variant of the SRM-2620 platform, featuring a 2:1 gear reduction that delivers 23% more torque for cutting through dense vegetation. Pro Tool Reviews names it Best Pro Gas; HGTV and The Spruce select it as their top gas pick. Recommended for homeowners who want commercial-grade durability or regularly face heavy overgrowth.
  • Stihl FS 91 R — A benchmark professional gas trimmer recommended by Pro Tool Reviews and named Best Gas by Better Homes & Gardens. Stihl’s extensive dealer and service network is a significant advantage for ongoing support. The related Stihl FS 70 R earns Consumer Reports’ second-highest gas score (82 out of 100). Note that Stihl products are typically available only through authorized dealers, not mass-market retailers.
  • Husqvarna 130L — Consumer Reports rates the Husqvarna 130L at 80 out of 100 for gas straight-shaft trimmers. Its RapidReplace trimmer head streamlines string loading, and the digital ignition provides reliable starting. A solid choice for homeowners who prefer Husqvarna’s widely available lineup.

Why It’s a Top Pick

The Worx WG170.2 earns the strongest consensus among budget and lightweight string trimmer picks. Wirecutter selects it as Best for Small Lawns, noting its full assortment of ergonomic adjustments and compact design. Better Homes & Gardens names it Best Budget, and Popular Mechanics also names it Best Budget. Bob Vila recommends it as both Best Lightweight and Best for Small Yards.

At under six pounds, the WG170.2 is one of the lightest string trimmers on the market. Its three-in-one design — precision trimmer, in-line wheeled edger, and mini-mower — provides versatility that no other model in this price range matches. Worx’s Command Feed technology releases more line at the push of a button, eliminating the need to bump the head against the ground. The 20V Power Share battery is compatible with more than 75 other Worx tools.

This trimmer is purpose-built for small to medium yards with light to moderate trimming needs. It is not designed for thick brush or extended heavy-duty use, which is why the Best Battery / Cordless segment exists for homeowners who need more power.

What Experts Like

  • Three-in-one design converts from trimmer to wheeled edger to mini-mower without tools
  • Under six pounds with seven handle positions and six rotating head settings for comfort
  • Command Feed technology releases line at the push of a button — no bumping required
  • 20V Power Share battery is compatible with a broad range of other Worx tools

Trade-Offs to Consider

  • 20V motor delivers less cutting power than 40V or 56V models, limiting effectiveness on thick weeds
  • 12-inch cutting swath is narrower than full-size trimmers, requiring more passes for larger areas
  • Battery runtime of approximately 20 minutes is best suited for small yards

Runners-Up

  • Black+Decker LST136 — TechGearLab’s Budget Pick (73 points) and Your Best Digs’ Best Overall, the Black+Decker LST136 offers a 40V battery with PowerCommand dial for adjusting between max power and max runtime. Its collapsible design and automatic feed spool make it convenient for storage and use. It did not match the Worx’s cross-source breadth among Primary sources.

How to Choose the Right String Trimmer for You

Decide between battery, gas, or corded based on your property size and trimming demands. Battery-powered trimmers are the right choice for most homeowners. They start with the press of a button, need minimal maintenance, run quietly, and produce no exhaust. Expect approximately 30-45 minutes of runtime per charge from a quality model. Gas trimmers make sense for properties larger than an acre or for regular clearing of thick overgrowth, where unlimited runtime outweighs the added noise, weight, and maintenance. Corded electric trimmers are the most affordable option but are limited by extension cord length and increasingly rare in expert recommendations.

Consider the battery ecosystem if you own or plan to buy other outdoor power tools. Major brands like EGO, Ryobi, Milwaukee, Makita, and DeWalt each offer broad lineups of tools that share batteries. Buying into a platform lets you use a single set of batteries across your trimmer, mower, blower, and chainsaw, which reduces cost and simplifies charging. If you already own cordless tools from one of these brands, a compatible trimmer is a natural choice.

Match the trimmer’s cutting swath and line diameter to your typical workload. Cutting swath — the width of the area the trimmer cuts in a single pass — typically ranges from 12 to 18 inches. Wider swaths cover ground faster but can be harder to maneuver in tight spaces. Line diameter matters too: thicker line (0.095 inches or above) cuts through heavier vegetation more effectively, while thinner line (0.065 inches) is lighter and better for fine grass but breaks more easily on tough weeds.

Pay attention to weight, balance, and shaft design for comfort during extended use. String trimmers range from under six pounds for lightweight models to over 12 pounds for heavy-duty options. Straight-shaft trimmers offer a longer reach and are generally preferred by taller users and for getting under bushes, while curved-shaft models can be easier to handle for some users. A telescoping or adjustable shaft helps match the trimmer to your height. A shoulder strap or harness attachment point is valuable for heavier models.

Evaluate the line-feed mechanism before you buy. The three common systems are bump feed (tap the head on the ground to release more line), automatic feed (line advances when the trimmer restarts), and push-button command feed. Experts broadly prefer bump feed for reliability, though EGO’s Powerload and Worx’s Command Feed represent newer approaches that simplify the process. Whatever system you choose, look for a trimmer head that reloads quickly when the spool runs out.
