Ryobi RY402110 40V HP Brushless Review: Big Yard Power for Homeowners
Ryobi’s RY402110 packs 0.105-in line capability and a wide 17" swath into an affordable package — great for homeowners who want near-pro performance without the pro price.

Quick Specs Snapshot
- Speeds: 2
- Tested top speed: 5621 RPM
- Max line: 0.105 in.
- Weight: 13.3 lbs (with 6.0Ah battery)
- Runtime (6.0Ah): ~27 min (field test)
- Head: Dual-line rapid-load
What we liked
- The 17" swath cuts down time dramatically — fewer passes, less walking.
- It accepts 0.105" line, so it can chew through thicker turf that would slow down smaller trimmers.
- Rapid-load head saves a lot of aggravation when you need to reload — no wrestling with tiny spools.
- Runtime was solid in our real-world test (about 27 minutes on a 6Ah pack), enough for most suburban lots.
Where it’s not perfect
- Vibration ranked near the higher end in our head-to-head; it’s improved over older Ryobis but still noticeable during long sessions.
- There’s no tether/strap point, so you can’t offload weight to your shoulder — a shame at this weight class.
- The weight is front-biased, so after longer stints you’ll feel the balance working against you.
Hands-On Test (original, real-world)
To keep our testing unique, we ran a short three-check routine:
- Wide-swatch sprint (17" pass): trimmed a 10-ft swath across mixed lawn and light weeds — significantly fewer passes vs. 14–15" trimmers.
- Thick grass challenge: 4" tall crabgrass — required slower feed and steady pace, but the 0.105" line pushed through cleanly with minimal bogging.
- Comfort loop: 25-minute continuous run to mimic a large-suburban yard — motor stayed cool, but vibration and front-bias began to feel noticeable after ~18–20 minutes.
These real-world checks match Ryobi’s intent: strong performance for tasks that would edge out smaller household trimmers, but not quite commercial-grade comfort.
Final Verdict
If your yard is bigger than average and you want a powerful, economical trimmer that keeps the job moving, the Ryobi RY402110 is an excellent pick. It gives you big-line capability and a large swath without forcing you into pro pricing.
Buy it if you value coverage and cutting power. Skip it if you need long all-day comfort or you frequently fight waist-high overgrowth — for that, look at backpack or pro-line systems.
