Best String Trimmers (Weed Eaters) in 2026: Gas, Battery, Electric

A string trimmer — or “weed eater,” as most people call it — might be the hardest-working tool in your lawn care arsenal. It does the detail work that makes the difference between a lawn that looks mowed and one that looks groomed: tight edges along fences, clean borders around beds, trimming under obstacles the mower can’t reach.

But with dozens of options across gas, battery, and electric power sources, choosing the right trimmer isn’t simple. Power levels vary wildly. Weight matters more than most people realize. And the line feed system — how the trimmer advances fresh cutting line — determines whether a session is pleasant or maddening.

This guide breaks down the best string trimmers across all categories for 2026, with honest pros and cons for each.

Gas vs. Battery vs. Corded Electric: Which Is Right for You?

Before getting into specific models, the power source decision is the most important choice you’ll make.

Gas String Trimmers

Gas trimmers run on a 2-cycle (or occasionally 4-cycle) engine fueled by a gas-oil mix. They offer unlimited run time, maximum power, and professional-grade performance.

Pros:

• Most powerful option — can handle heavy, overgrown brush
• No battery management or charging required
• Unlimited runtime for large properties
• Better performance in demanding professional applications

Cons:

• Heavier and louder than battery models
• 2-cycle engines require fuel mixing and more maintenance
• More difficult to start (especially in cold weather)
• Emit exhaust fumes
• More vibration than electric alternatives

Best for: Large properties (half acre+), heavy-duty trimming applications, professional use.

Battery String Trimmers

Battery (cordless) trimmers have become the dominant choice for residential users in 2026. Modern 40V–82V battery platforms deliver performance that rivals gas in most residential applications, with the added benefits of quiet operation, zero emissions, and easy startup.

Pros:

• Near-gas power on premium 56V–82V platforms
• Quiet operation — no noise complaints from neighbors
• No fuel mixing, no emissions
• Instant start — press a button and go
• Less vibration for better operator comfort

Cons:

• Limited runtime (typically 30–60 minutes per charge)
• Battery adds weight, especially in backpack or belt-pack configurations
• Battery and charger can add significant cost if not already in an ecosystem

Best for: Most residential lawns under half an acre; homeowners who value convenience and low maintenance.

Corded Electric String Trimmers

Corded electric trimmers offer consistent power without battery concerns, at typically the lowest price point.

Pros:

• Consistent, unlimited power as long as it’s plugged in
• Lightest weight among powered trimmers
• Lowest purchase price
• No battery degradation over time

Cons:

• Limited by cord length (typically 50–100 feet)
• Cord management is inconvenient and potentially dangerous
• Not practical for large or complex lawns

Best for: Small, simple properties close to power outlets; budget-conscious buyers.

The EGO ST1521S consistently tops best-trimmer lists, and for good reason. The 56V Arc Lithium battery platform delivers power that genuinely rivals gas trimmers in most residential conditions. The variable-speed trigger lets you dial in speed for light edging or maximum power for tough growth.

Price: ~$129 (tool only) | Power: 20V MAX XR | Cutting Swath: 13 inches | Weight: 7.8 lbs

The DEWALT DCST922 is the go-to pick for anyone already invested in the DEWALT 20V MAX battery platform. It shares batteries with hundreds of DEWALT tools, which is a genuine convenience advantage. The XR motor delivers strong, consistent power for a 20V system.

The bump-feed line advance is predictable and reliable. The gear drive technology provides 20% more torque than the standard motor version, which handles heavier grass better than expected for a 20V platform.

Price: ~$119 (tool only) | Power: 40V HP Brushless | Cutting Swath: 15 inches | Weight: 7.2 lbs

Ryobi’s 40V HP brushless trimmer delivers strong performance at a very accessible price. The brushless motor is a notable step up from brushed motors — more efficient, generates less heat, and should last significantly longer.

The dual-line cutting system handles thick grass better than single-line designs, and the 40V platform hits a sweet spot between the limited power of 20V tools and the cost of 56V–80V systems.

Echo is the professional lawn care industry’s favorite brand for entry-level gas trimmers, and the SRM-225 is the model that built that reputation. The i-30 starting system makes it significantly easier to start than older 2-cycle designs. The 21.2cc engine hits the sweet spot of power and fuel economy for residential applications.

Echo’s build quality is genuinely commercial-grade, even on their entry-level models. The 5-year consumer warranty is the best in gas trimmers.

The Husqvarna 128LD earns its place on this list through versatility. It’s a detachable shaft design that accepts Husqvarna’s full range of attachments: edger, cultivator, hedge trimmer, and more. If you want one engine powering multiple tools, the 128LD is the smartest investment.

The 28cc engine provides more power than the Echo SRM-225, handling heavier growth with ease. The T35 tap-and-go trimmer head is reliable and fast to reload.

Stihl is synonymous with professional outdoor power equipment, and the FS 56 RC-E is their benchmark residential gas trimmer. The Easy2Start (E) system eliminates the arm-straining cold starts common with older 2-cycle engines. The anti-vibration system measurably reduces fatigue on longer sessions.

Build quality is simply excellent — the FS 56 RC-E should last 10–15 years with basic maintenance. Stihl sells exclusively through independent dealers, which means better service support than big-box brands.

Pros:

• Excellent anti-vibration system reduces fatigue
• Dealer-only distribution means quality service support
• Outstanding long-term reliability

At just 6.3 lbs, the Greenworks 40V is one of the lightest powered trimmers available. For users who find standard trimmers fatiguing — smaller statures, older users, or anyone with shoulder or wrist concerns — the weight reduction is genuinely significant.

Performance is competent for a 40V platform. The automatic line feed works well in normal grass conditions. The Greenworks 40V battery platform is broadly compatible across their mowing, blowing, and trimming lineup.

Price: ~$99 (with battery) | Power: 20V | Cutting Swath: 12 inches | Weight: 5.3 lbs

The Worx WG163 earns a unique spot on this list through its Command Feed spool system and instant conversion from trimmer to in-line edger. Rotating the trimmer head 90 degrees converts it to a wheel-guided edger — no additional tool required. For homeowners who want both trimming and edging from a single lightweight tool, this is compelling.

Pros:

• Instant conversion to in-line edger
• Very lightweight (5.3 lbs)
• Includes battery and charger
• Command Feed spool eliminates bump-feeding

String Trimmer Buying Guide

Line Feed System: Bump-Feed vs. Auto-Feed vs. Fixed Line

Bump-feed: Tap the head on the ground to advance fresh line. Reliable and widely used, but can inadvertently advance line on uneven ground.

Auto-feed: Electronically or mechanically senses when line is short and advances automatically. More convenient, occasionally over-feeds.

Fixed-line (star-wheel): Line segments clipped into the head. No automatic advancement — you replace segments when they break. Very common on commercial straight-shaft models. Most reliable and handles heavy growth best.

Shaft Type: Straight vs. Curved

Straight shaft: Longer reach, better for trimming under obstacles, preferred by professionals. Required for most heavy-duty applications and commercial work.

Curved shaft: More natural ergonomic position for most users, typically lighter. Fine for standard residential trimming.

Cutting Swath

A wider cutting swath means fewer passes — but wider heads create more stress on the motor and line. For most residential lawns, 13–17 inches is the ideal range.
