EGO Power+ ST1521S – Best Cordless Power Meets Precision

Specifications & Features:

• 15″ dual-action steel blade

• 56V ARC Lithium™ battery and Rapid Load™ head

• Brushless motor for consistent torque

• Carbon-fiber shaft for reduced weight

• Run time: 45 minutes

• Weight: 12.0 lb

Stepping up to the EGO Power+ ST1521S felt like trading a station wagon for a sports car. Its Rapid Load™ system snaps line into place in seconds—no more manual threading or frustrating spool changes. In backyard tests on thick privet and clover patches, the ST1521S delivered consistent power until the battery indicator hit 10%, outperforming lower-voltage trimmers by a clear margin.

Real-World Performance: The dual-action blade design not only cuts cleaner but also ejects debris effectively, preventing head jams. I tackled an overgrown 50-foot hedge line without a single tangle. The vibration-dampening handle kept fatigue at bay, letting me finish the job a full 20% faster than my old gas model.

Pros: Near-gas power without emissions; tool-free line replacement; excellent user feedback—4.8/5 from 3,000+ reviewers. Cons: Slightly heavier than 20V competitors; premium price (~$299).

Usage Tip: Always carry a spare battery and keep it charged. A quick battery swap costs less time than refilling a gas tank.

Makita XRU23Z – Ultra-Quiet Brushless Runtime Champion

Specifications & Features:

• 17″ cutting swath

• Dual 18V LXT batteries (sold separately)

• Brushless motor up to 6,000 RPM

• Tool-less auto-feed head

• Run time: Up to 60 minutes

• Weight: 6.6 lb

Makita’s XRU23Z merges whisper-quiet operation with a broad cutting path. During early-morning sessions, its 88 dB noise level didn’t rouse the neighbors. The dual-battery setup powered through an acre of tall fescue without drop-off, and the auto-feed head meant uninterrupted focus on my cutting line.

Real-World Performance: With a 17″ swath, the XRU23Z carved through grass and light brush 15% faster than 13″ models. The balanced center-of-gravity design minimized wrist fatigue even after 45 minutes of trimming.

Pros: Long runtime; wide cutting path; lightweight and comfortable. Cons: Batteries sold separately (~$150 each); slight vibration under full throttle.

Usage Tip: Rotate batteries front-to-back for even weight distribution and longer-endurance sessions.

Husqvarna 122HD60 – Professional Gas-Powered Muscle

Specifications & Features:

• 24″ dual-action blade

• 21.7 cc two-stroke gas engine

• Easy-Start™ primer and choke

• Anti-vibration mounts

• Run time: ~50 minutes per 14 oz tank

• Weight: 11.2 lb

When raw torque is non-negotiable, the Husqvarna 122HD60 reigns supreme. Its two-stroke engine roared through thick privet and bamboo shoots that stumped electric trimmers. The Easy-Start™ system fired on the first pull, even after weeks of idle storage.

Real-World Performance: During a heavy-duty test on roadside brush, the 122HD60 never bogged down. Anti-vibe technology reduced hand fatigue so significantly that I could work for nearly an hour straight—a first with gas models.

Pros: Unmatched power; all-weather reliability; pro-grade durability. Cons: Heaviest option; higher noise and emissions.

Usage Tip: Mix high-grade two-stroke oil at the manufacturer’s recommended ratio and clean the air filter after every 5 hours of use.

Greenworks 21212 – Featherweight Cordless Trimming

Specifications & Features:

• 13″ nylon line cutting head

• 24V Lithium-Ion battery

• Pivoting head for edging

• Adjustable shaft length

• Run time: 30 minutes

• Weight: 5.4 lb

At just 5.4 pounds, the Greenworks 21212 is practically paperweight. I danced the trimmer around flower beds and climbed slopes without a hint of strain. Its pivoting head swings to edging mode in seconds, and though the 13″ swath means more passes, the nimbleness pays off in tight spots.

Real-World Performance: The semi-auto bump feed system worked reliably once I mastered a light bump rhythm. In garden border tests, the trimmer delivered clean lines with minimal user effort.

Pros: Ultra-light; easy to maneuver; versatile trim/edge functionality. Cons: Limited run time under heavy load; narrower cutting path.

Usage Tip: Store the battery at 40–50% charge in a cool, dry place to extend its lifespan.

Black+Decker LST300 – Best Budget Trimmer

Specifications & Features:

• 12″ cutting path

• 20V MAX Lithium-Ion battery

• 2-in-1 rotating shaft

• Automatic feed spool

• Run time: 40 minutes

• Weight: 5.7 lb

For under $100, the Black+Decker LST300 punches above its weight. Its auto-feed spool maintains a steady line without bumping, and the rotating shaft locks tightly for crisp edging. It’s perfect for quick weekend touch-ups, though thick brush drains it faster than pricier models.

Real-World Performance: In tests on crabgrass and clover, the LST300 kept pace with pricier 20V units—missing only raw power against dense vines.

Pros: Excellent value; battery and charger included; lightweight. Cons: Not suited for heavy-duty clearing; occasional feed misfires if spool isn’t seated perfectly.

Usage Tip: Replace the spool cartridge yearly to prevent common feed issues.
