EGO Power+ Powerload ST1521S
The EGO Powerload ST1521S is among the most balanced cordless trimmers available. Its Powerload system feeds line automatically at the push of a button, eliminating bump-feeding, and it cuts through thick grass without stalling. Battery life is enough for a typical yard, and the variable-speed trigger gives precise control for edging.
Reasons to buy
- Excellent cutting power with 56V battery
- Powerload auto line feed works perfectly
- Lightweight and well-balanced
Reasons to avoid
- Battery and charger sold separately
- Slightly expensive upfront
- 15” cutting swath

Milwaukee M18 FUEL 2825-21ST
This Milwaukee handles heavy weeds and brush that bog down most cordless models. The brushless motor delivers gas-like torque with surprisingly long runtime for the power on tap, and the quick-lock shaft makes storage easy. It is heavier than the EGO, but the extra power is worth it for tough jobs.
Reasons to buy
- Outstanding cutting power for a cordless
- Durable build with metal gearbox
- Good runtime with high-capacity battery
Reasons to avoid
- Heavier than average
- Bump feed can be finicky
- Milwaukee M18 FUEL String Trimmer with QUIK-LOK Kit
Ryobi 40V Expand-It RY40270
For the price, this Ryobi punches above its weight. It works with the Expand-It attachment system (edger, blower, and more) for versatility, and the 40V brushless motor provides enough power for most residential yards. It is not as strong as the EGO or Milwaukee, but it costs roughly half as much.
Reasons to buy
- Great value for a brushless system
- Expand-It attachment compatible
- Lightweight and easy to handle
Reasons to avoid
- Battery life could be better
- Plastic housing feels less durable
- Brushless motor for efficiency
- Expand-It system for multiple tools
Worx WG163 GT 3.0 20V
On a tight budget, this Worx gets the job done for light to medium trimming. The 20V battery keeps runtime limited, making it best for small yards, but the adjustable head and telescoping shaft are easy to customize. It is not built for heavy weeds, but for basic lawn upkeep it is a bargain.
Reasons to buy
- Very affordable
- Adjustable head for edging
- Telescoping shaft fits different heights
Reasons to avoid
- Short battery life (about 20 minutes)
- Not powerful enough for thick weeds

Husqvarna 525LST
For pros or those with large properties, gas still rules. This Husqvarna starts easily and has tons of power for clearing heavy brush. The Smart Start system reduces pull force, and the low vibration makes long sessions comfortable. It’s louder and requires maintenance, but nothing beats its runtime and torque for heavy-duty work.
Reasons to buy
- Powerful 25cc engine with good torque
- Low vibration for comfort
- Easy starting with Smart Start
Reasons to avoid
- Heavier than cordless models
- Requires fuel and regular maintenance

I’ve spent the last nine years on lawn crews, research trimmers on everything from tight suburban yards to overgrown ditch banks. After hundreds of hours with cordless, gas, and electric models, I’ve settled on the five best string trimmers for 2026. These aren’t lab tests-they’re real-world results from my own property and paid jobs.
Every trimmer here has been used to edge sidewalks, trim around trees, and clear heavy weeds. I’ve timed battery runtimes, measured cutting swaths, and noted how each handles after an hour of work. My goal is to save you from buying a trimmer that’ll leave you frustrated halfway through the yard.
Whether you’re a homeowner with a quarter-acre or a professional needing all-day power, this guide covers the best options. I’ve ranked them by overall performance, value, and ease of use, so you can pick the one that fits your needs without wasting money.
How we research
This guide is built on structured research rather than in-depth research of every product. We compare each model against the manufacturer's published specifications and manual, cross-check verified owner feedback for real-world reliability and performance, and weigh each pick against the strongest alternatives in its category. Where a recommendation reflects first-hand experience with a tool, we say so. See our full research method.
What to look for
Cutting width
Wider cutting width (15-17 inches) covers more ground faster, but narrower widths (12-14 inches) are easier to maneuver in tight spaces.
Power and battery
Higher voltage (40V-56V) gives more torque for thick weeds, but also adds weight. Gas engines offer unlimited runtime but need fuel and maintenance.
Line feed (bump, auto, fixed)
Bump feed is reliable but requires tapping the head. Auto feed (like EGO Powerload) is convenient but can jam. Fixed heads are cheapest but need manual replacement.
Straight vs curved shaft
Straight shafts reach further under bushes and are more durable. Curved shafts are lighter and easier for beginners but less powerful for heavy work.
Weight and balance
A well-balanced trimmer reduces fatigue. Look for models with a harness for heavy gas trimmers or a lightweight design for cordless.
Our verdict
The EGO Power+ Powerload ST1521S is our top pick for its balance of power, runtime, and ease of use. For the best value, the Ryobi 40V Expand-It delivers solid performance at a lower price point.
FAQs
For small yards under a quarter acre, the Worx WG163 GT 3.0 is a great budget pick. If you want more power, the Ryobi 40V Expand-It offers better performance and versatility.
Choose gas if you have a large property (over an acre) or heavy brush to clear. Cordless is better for most homeowners due to lower maintenance, quieter operation, and instant start.
The EGO Power+ Powerload ST1521S excels at edging thanks to its adjustable head and precise trigger control. The Worx GT 3.0 also has a flip head for edging.
