Ryobi 18V Vs 40V Hedge Trimmer: Which Should You Buy
Both trim well; 18V favors light yards, 40V powers through thick growth.
Your hedges look wild. Your weekend is short. I’ve been there. I tested the ryobi 18v vs 40v hedge trimmer on a small city yard and my neighbor’s taller, thicker shrubs. Both are solid. But they shine in different ways. The 18V is light and nimble. The 40V is strong and fast. I’ll share how each felt in real use so you can pick the right fit.
Is Ryobi 18V hedge trimmer Good?
Yes, for most small to mid yards. It is light, easy, and friendly. If you trim boxwoods, privet, or new growth, it does great. It also makes sense if you already own Ryobi 18V ONE+ batteries. It is not made to chew old, woody branches all day. But for tidy touch-ups, it is a star.
On a Saturday, I shaped a front hedge run in under 20 minutes. My arm did not ache. The tool felt balanced. I could reach the low spots and edges with no hassle. Another time, I trimmed a long fence line after work. The 18V made quick, clean passes and did not wake the baby inside. That quiet, low-vibe feel won me over.
What Makes It Stand Out / Key Features
- 18V ONE+ platform; shares batteries with many tools
- About 22-inch dual-action blade for clean cuts
- Lightweight build for low fatigue
- Good for 3/4-inch soft stems (light to moderate growth)
- Simple trigger and safety lock for quick starts
What I Like
- Very light and easy to control
- Quiet for a hedge trimmer; low vibration feel
- Great for weekly touch-ups and shaping
- Battery swaps with other Ryobi 18V tools
- Affordable entry point for new homeowners
- Blade is long enough for smooth, straight edges
What Could Be Better
- Not ideal for thick, woody branches
- Slows down in very dense hedges
- Runtime can dip with older 1.5Ah packs
My Recommendation
If you have a small yard, lighter shrubs, and want comfort first, choose this. Great value and easy to live with.
| Best For | Why |
|---|---|
| Small to mid-size hedges | Light, nimble, and efficient for light growth |
| Budget-minded users | Lower cost and uses 18V batteries you may own |
| Quick weekly trims | Fast setup, low noise, and clean finish |
Is RYOBI 40V HP Brushless Hedge Trimmer Good?
Yes, if you want power. It is strong, fast, and built for dense hedges. The brushless motor and 40V pack drive big jobs. It costs more and weighs more. But if you fight old growth or wide hedges, it pays off.
I used it on a tall holly row that the 18V struggled with. The 40V HP sliced through thick tips in one pass. The longer blade helped keep lines straight at height. I also cleared a year of overgrowth on a corner lot. The 40V ran longer per charge and never felt bogged down. It felt like a pro tool without the cord.
What Makes It Stand Out / Key Features
- 40V HP brushless motor for high torque and speed
- About 26-inch blade for wide, straight passes
- Handles thicker branches (up to about 1 inch)
- Rotating handle for vertical and horizontal cuts
- Part of the Ryobi 40V outdoor lineup
What I Like
- Power that does not stall in dense hedges
- Longer blade speeds up big jobs
- Brushless motor feels smooth and efficient
- Rotating handle improves control on side cuts
- Strong runtime with higher Ah packs
- Pro-grade results without a cord or gas
What Could Be Better
- Heavier; arms feel it on long sessions
- Higher cost, especially if you need a battery
- Overkill for very small yards
My Recommendation
Pick this if your hedges are big, tough, or thick. It is a time saver and worth it for demanding yards.
| Best For | Why |
|---|---|
| Large or dense hedges | High power and longer blade cover more in less time |
| Occasional heavy clean-ups | Cuts thicker, older growth with fewer passes |
| Owners of Ryobi 40V tools | Shares 40V batteries across the system |
