Quick verdict
The EGO Power+ Powerload ST1521S is my 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.
EGO Power+ Powerload ST1521S
I’ve used this trimmer for two seasons and it’s the most balanced cordless model I’ve tried. The Powerload system feeds line automatically with a button, saving me from bumping the head on the ground. It cuts through thick grass without stalling and the battery lasts long enough for my entire yard. The variable speed trigger gives me precise control for edging.
The 5 best String Trimmers of 2026, tested and ranked on real performance, build and value. Our top pick is the EGO Power+ Powerload ST1521S, with pros, co...
I’ve spent the last nine years on lawn crews, testing 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 test
I test trimmers on my own lawn and a few neighbors’ properties, which include thick St. Augustine grass, Bermuda, and patches of weeds. For each model, I run through at least three full battery charges or a full tank of gas, timing how long it takes to trim a standard 5,000 sq ft lot. I also test edging along concrete and brick, as well as heavy-duty cutting of brush up to 1 inch thick.
I evaluate cutting power by how easily the trimmer slices through tall grass and weeds without bogging down. Runtime is measured with the included battery or fuel capacity. Handling includes weight balance, vibration, and how easy it is to maneuver around obstacles. Value compares price to features and long-term durability.

The picks, reviewed
EGO Power+ Powerload ST1521S
I’ve used this trimmer for two seasons and it’s the most balanced cordless model I’ve tried. The Powerload system feeds line automatically with a button, saving me from bumping the head on the ground. It cuts through thick grass without stalling and the battery lasts long enough for my entire yard. The variable speed trigger gives me 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
- Dual-feed spiral twist 0.095in. Line
Milwaukee M18 FUEL 2825-21ST
This trimmer is a beast-it handles heavy weeds and brush that would bog down most cordless models. The brushless motor delivers gas-like torque, and the battery lasts surprisingly long given the power. I love the quick-lock shaft for easy storage. It’s heavier than the EGO, but the power trade-off 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 trimmer punches way above its weight. I’ve used it with the Expand-It attachments (edger, blower) and it’s a versatile system. The 40V battery gives enough power for most residential yards, and the brushless motor keeps it efficient. It’s not as powerful as the EGO or Milwaukee, but it’s half the cost.
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
If you’re on a tight budget, this trimmer gets the job done. I was surprised by how well it handles light to medium trimming. The 20V battery is small, so runtime is limited, but it’s perfect for small yards. The adjustable head and telescoping shaft make it easy to customize. It’s not for heavy weeds, but for basic lawn maintenance, it’s a steal.
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

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 my 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.
