Introduction
In my decade trimming gardens and parks, I’ve come to expect three things from a string trimmer: reliable starts, steady torque under real-world conditions, and no-fuss line feed. Ryobi hits all three marks, and in 2025 they’ve delivered refinements across gas, corded, and battery models. Below, you’ll find detailed reviews, usage scenarios, maintenance tips, and FAQs—all written in plain English by someone who has wrestled with tangled lines and aching arms so you don’t have to.

- Versatile Power Sources: Choose gas for heavy brush, corded for uninterrupted work, or cordless for freedom.
- User-Friendly Design: Tool-free head changes, easy-access filters, and intuitive controls.
- Balanced Ergonomics: Thoughtful handle placement and anti-vibration features keep fatigue at bay.
- Straightforward Maintenance: Clear line path, simple fuel mixes, and minimal electronics.
Before you buy, consider: yard size, desired runtime, engine vs. battery upkeep, head-feed style, and weight. Let’s compare the contenders.

In-Depth Reviews
1. Ryobi RLT3045 (40V Max): The All-Around Cordless Workhorse
Last Saturday I grabbed the RLT3045 for my half-acre yard. A quick press of the trigger woke the brushless motor; a tap of Command Feed™ advanced fresh line instantly. That 4 Ah battery carried me through edging, border trimming, and light clearing—about 45 minutes—without hiccup. At 8.6 lbs it balanced nicely, letting me maintain crisp lines around my garden beds and driveways without stopping.
Pros
- Immediate, no-fuss line feed
- Reliable 45-minute runtime on a 4 Ah pack
- Smooth throttle and balanced handling
Cons
- Holding the Command Feed™ button too long wastes line
- Battery pack adds bulk behind the handle
Pro Tip: Tap the feed button briefly—get just enough line each time and stretch your runtime.
2. Ryobi RLT1830 (18V): Feather-Light Precision Trimmer
When time’s tight and your yard’s small, the RLT1830 is gold. At just 7.8 lbs, I threaded around tight flower beds and along patio edges in minutes flat. The tool-free bump-feed dial lets you adjust tension by hand, so switching from cutting thick grass to edging delicate borders is effortless. On a 2 Ah battery, I got about 30 minutes—ideal for small lawns or quick spruce-ups.
Pros
- Ultra-light for nimble control
- Easy, tool-free line dial
- Whisper-quiet brushless motor
Cons
- Limited to 30 minutes per charge
- 13″ head means more passes on large plots
Pro Tip: Store a second 2 Ah pack on the charger—hot-swap mid-trim to finish any job.
3. Ryobi RTL55150H (Gas): Muscle for Tough Overgrowth
For overgrown spots that laugh at battery packs, the RTL55150H gas model shines. One firm pull on its 51.7 cc engine, and that Auto-Feed™ dual-action head kept feeding fresh line as I pressed into thick crabgrass and volunteer vines. Over a 60-minute stretch, I cleared a roadside verge and never ran low on power or fuel. At 12.3 lbs it’s a workout—but the loop handle and comfortable grips make it manageable.
Pros
- Unmatched torque for dense brush
- Continuous Auto-Feed™ keeps you cutting
- Large 32 oz tank for long sessions
Cons
- Weight takes stamina—plan breaks
- Requires precise 50:1 fuel mix
Pro Tip: Pre-mix fuel in a marked jug the night before—no guesswork at the tank.
4. Ryobi RLE22002B (Corded): Plug-In and Go
Time was tight before a family visit, so I plugged in the RLE22002B. That 8 Amp motor spun the Rapid-Reload™ head to life instantly. No cord-trouble, no battery anxiety—just steady power until the plug came out. At 9.2 lbs it felt sturdy but never heavy, slicing through early morning grass in record time.
Pros
- Unlimited runtime—just keep the cord in sight
- Quick head reload—twist, and you’re back to work
- Affordable, no-battery or gas costs
Cons
- Cord limits your range—plan outlets or use a long, bright cord
- Slower single-line feed through thick tufts
Pro Tip: Loop your extension cord over your shoulder strap—keeps it out of your feet and out of trouble.
5. Ryobi RLT721 (60V Max): Marathon Trimming
When I needed to tackle a two-acre property, the RLT721 stepped up. That 60 V Max system and a 5 Ah battery let me go for nearly 60 minutes in eco mode—plenty to edge, trim, and clear wider swaths. The 16″ head covers ground fast; at 9.9 lbs it’s a bit heavier, but the extra reach makes up for it. Throw in Ryobi’s brushless efficiency and you’ve got a cordless titan.
Pros
- Longest runtime in the Ryobi lineup
- High-torque brushless motor
- Broad 16″ head speeds up big jobs
Cons
- Bulkier pack behind the handle
- Premium price for premium performance
Pro Tip: Switch between eco and boost speeds depending on grass thickness—stretch that battery even further.
