Best Ryobi Hedge Trimmer
The RYOBI 40V HP Brushless 24 in. Hedge Trimmer (RY40650) is the strongest all-around pick in Ryobi's hedge trimmer lineup because it pairs a 5/8 in. cutting capacity with a brushless motor that holds power through thicker growth. Most buyers get tripped up not by blade length but by battery family, since Ryobi's 18V ONE+ and 40V hedge trimmers use separate batteries and chargers that are not interchangeable.
Quick answer
For most yards, the RYOBI 40V HP Brushless 24 in. Hedge Trimmer (RY40650) delivers the best cutting capacity and control. Owners already invested in 18V ONE+ batteries get nearly the same performance from the RYOBI ONE+ HP 18V Brushless 22 in. Hedge Trimmer (P2690) or the standard RYOBI ONE+ 18V 22 in. Hedge Trimmer (P2603) at a lower price.

What Matters Most for This Category
Blade length and tooth spacing should match hedge size and stem thickness, not just yard size. A 24 in. blade covers more per pass on tall or wide hedges but adds weight and leverage that shows up in your wrist and shoulder over a long session, while a 22 in. blade is easier to control on shorter or tightly shaped hedges. Tooth gap matters more than blade length for thick or woody stems, since a trimmer rated for 1/2 in. branches will bog down or bind on anything thicker, while a 5/8 in. rated blade like the HP models handles overgrown growth more cleanly. Battery family is the tradeoff most buyers miss, since Ryobi's 18V ONE+ and 40V platforms use different batteries and chargers, so the decision often comes down to what battery ecosystem you already own. Always check whether a listed weight is the bare tool or the working weight with the battery installed, because a kit that looks light on paper can run a full pound or more heavier once the battery is attached.

RYOBI 40V HP Brushless 24 in. Cordless Battery Hedge Trimmer
Best OverallPros
- Brushless motor holds RPM under load better than brushed motors on thicker stems
- 5/8 in. cutting capacity clears woody growth that jams smaller-capacity trimmers
- Ships as a complete kit with battery and charger included
Cons
- Working weight with the battery installed is noticeably heavier than the 18V ONE+ models, which matters on extended overhead cuts
- 40V batteries are not compatible with Ryobi's 18V ONE+ tools, so it does not help owners already invested in that platform
This is Ryobi's flagship battery hedge trimmer, built around a brushless motor on the 40V lithium platform rather than the 18V ONE+ system. The 24 in. dual-action blade is rated for branches up to 5/8 in. in diameter, thicker than Ryobi's standard 18V or non-HP 40V trimmers can handle cleanly. It ships as a kit with a 40V lithium battery and charger rather than as a bare tool. Ryobi backs its 40V and HP outdoor tools with a 5-year limited warranty, longer than the standard 3-year coverage on base ONE+ tools.
RYOBI ONE+ 18V 22 in. Cordless Battery Hedge Trimmer
Best ValuePros
- Bare-tool pricing is the lowest cost of entry in Ryobi's cordless hedge trimmer lineup
- Shares batteries and chargers with the rest of the 18V ONE+ tool lineup
- 22 in. blade is easier to control one-handed on shorter hedges than the 24 in. models
Cons
- 1/2 in. cutting capacity struggles on thicker, woody stems that the HP and 40V models clear easily
- No battery or charger included, so first-time Ryobi buyers need to add that cost separately
Sold as a bare tool, this model is priced for buyers who already own an 18V ONE+ battery and charger from another Ryobi tool. The 22 in. dual-action blade is rated for branches up to 1/2 in. in diameter, enough for routine shaping of shrubs and small to mid-sized hedges. It uses the same 18V ONE+ pack that powers Ryobi's drills, trimmers, and blowers, so current ONE+ owners avoid buying a second battery system. Ryobi backs it with a 3-year limited tool warranty.
RYOBI 40V 24 in. Cordless Battery Hedge Trimmer
Best for Large HedgesPros
- Comes as a complete kit with battery and charger, unlike the bare-tool 18V ONE+ option
- 24 in. blade covers more per pass than any 18V ONE+ model on long hedgerows
- 40V battery also powers other Ryobi 40V outdoor tools like mowers and blowers
Cons
- 1/2 in. cutting capacity is the same as the cheaper 18V ONE+ trimmer despite the larger battery platform
- Working weight with the battery attached is the heaviest in this lineup, which shows up on overhead trimming
This is the non-HP 40V hedge trimmer, sold as a kit with a 40V lithium battery and charger included. The 24 in. blade matches the length of the HP model above but uses a standard motor and a 1/2 in. cutting capacity rather than the HP's 5/8 in. rating. Working weight with the battery installed runs close to 10.7 lbs, noticeably more than the bare 18V ONE+ trimmer, so it is worth handling in person if you plan to trim overhead for long stretches. Ryobi covers it with the extended warranty applied to its 40V outdoor line.
RYOBI ONE+ HP 18V Brushless 22 in. Cordless Battery Hedge Trimmer
Best LightweightPros
- Matches the 5/8 in. cutting capacity of the 40V HP model while staying on the lighter 18V ONE+ platform
- Brushless motor draws less from the battery than the brushed 22 in. base model
- Compatible with the same ONE+ batteries used across Ryobi's drills, blowers, and trimmers
Cons
- 22 in. blade covers less per pass than the 24 in. 40V models on long or tall hedges
- Sold as a bare tool, so battery and charger are an added cost if you are new to ONE+
This model brings the HP brushless motor line to the 18V ONE+ platform instead of the heavier 40V system. It keeps the 22 in. blade length of the base P2603 but raises cutting capacity to 5/8 in. thanks to the brushless motor, and it is sold as a bare tool. Because it runs on the same 18V ONE+ battery as dozens of other Ryobi tools, current ONE+ owners get HP-level cutting capacity without switching battery platforms. It carries Ryobi's 5-year tool warranty, matching the coverage on the 40V HP model.
RYOBI ONE+ 18V Cordless Pole Hedge Trimmer
Best for ReachPros
- Pivoting head angles the blade to follow the top profile of a hedge without repositioning a ladder
- Shares the 18V ONE+ battery with the rest of the platform
- Telescoping shaft adjusts for different hedge heights
Cons
- Smaller 18 in. blade and lower cutting capacity than the handheld models make it a poor primary trimmer for dense hedges
- Added length and pivoting head make it more front-heavy and tiring to hold overhead than a standard hedge trimmer
This pole hedge trimmer extends the 18V ONE+ platform to overhead hedges, with a telescoping shaft and a pivoting 18 in. head that adjusts for angled cuts along the top of a hedge. It is built for reach rather than raw cutting speed, so the blade and cutting capacity are smaller than the handheld 22 in. and 24 in. models above. It runs on the same 18V ONE+ battery as Ryobi's other ONE+ tools and is sold as a bare tool. The extended reach removes the need for a ladder on hedges taller than about 6 to 7 feet.
RYOBI ONE+ 18V Cordless Battery Grass Shear and Shrubber Trimmer
Best for Detail WorkPros
- Two interchangeable heads cover both lawn edging and light shrub shaping with one tool
- At about 2.2 lbs, it is easy to use one-handed for extended detail work
- Uses the same 18V ONE+ battery as the rest of the platform
Cons
- Not built to cut branches thicker than light new growth, so it cannot replace a dedicated hedge trimmer on an established hedge
- Narrow shear and shrubber blades make it slow on any hedge longer than a few feet
This is a two-in-one tool rather than a dedicated hedge trimmer, switching between a narrow grass shear head for lawn edges and borders and a wider shrubber blade for shaping small shrubs and low hedges. At roughly 2.2 lbs it is far lighter than any of the dedicated hedge trimmers above, since it is not designed to cut through thick branches. It runs on the same 18V ONE+ battery as the rest of the platform and is sold as a bare tool. It fits buyers whose hedges are really more like foundation shrubs or short borders than a tall privacy hedge.
RYOBI 21 in. 22cc Gas Hedge Trimmer
Best Gas-PoweredPros
- Runs on a full tank without waiting on battery charge time
- Not tied to a battery platform, so it works for buyers with no existing Ryobi ONE+ or 40V tools
- 22cc engine keeps consistent power through a full trimming session
Cons
- Requires fuel mixing and periodic engine maintenance that none of the battery models need
- Shorter 2-year warranty than the 3 to 5-year coverage on Ryobi's battery-powered hedge trimmers
This is Ryobi's gas-powered alternative for buyers who do not want to manage batteries at all, or who trim hedges far from a charging setup. It runs on a 22cc two-cycle engine with a 21 in. dual-action blade and requires mixed gasoline and 2-cycle oil rather than a battery pack. Because it is not tied to either the 18V ONE+ or 40V battery platforms, it does not share any consumables with Ryobi's other cordless outdoor tools. Gas outdoor power equipment from Ryobi typically carries a 2-year warranty, shorter than the coverage on its battery-powered lines.
Who Should Avoid the Top Pick
The RY40650's biggest limitation is its working weight and price relative to the 18V ONE+ lineup, so buyers who already own 18V ONE+ batteries and only need to maintain a modest hedge should choose the P2603 or P2690 instead. Anyone without any existing Ryobi battery should also weigh whether to commit to the 40V platform or the more widely shared 18V ONE+ platform before buying.
Before You Buy
Measure your actual hedge height, width, and stem thickness before choosing a blade length, since a 24 in. blade only helps if you have enough hedge length to justify the extra weight. Check which battery platform, 18V ONE+ or 40V, you already own or plan to buy into, since the packs and chargers are not interchangeable between them. Confirm whether the listing price includes a battery and charger or is tool-only, and if a weight is listed, check whether it is the bare tool or the working weight with the battery installed.
FAQs
Should I trust the cutting capacity and weight specs on a marketplace listing by themselves?
Cross-check them against Ryobi's own product page when possible, since marketplace listings sometimes show a bare-tool weight next to a kit price, or list an older cutting capacity spec after a running model update.
Can ToolBuyerHub recommend a Ryobi hedge trimmer without hands-on testing?
This page compares manufacturer-published specifications and recurring owner-feedback themes across each battery platform, rather than claiming lab or hands-on testing that did not happen.
Are 18V ONE+ and 40V Ryobi batteries interchangeable?
No. The 18V ONE+ platform and the 40V platform use separate batteries and chargers, so a hedge trimmer on one platform will not run on batteries from the other.
How often is this page checked for accuracy?
This page is reviewed periodically as Ryobi updates its hedge trimmer lineup or changes published specifications, and it is updated when a model is discontinued or replaced.
What cutting capacity do I actually need?
Match it to your thickest stems, not your hedge's overall size. A 1/2 in. rated trimmer is fine for regular shaping, but hedges with woody, overgrown stems need the 5/8 in. capacity found on the HP models.
Our verdict
For most residential hedges, the RYOBI 40V HP Brushless 24 in. Hedge Trimmer (RY40650) is the strongest pick because its 5/8 in. cutting capacity and 24 in. blade handle both routine shaping and overgrown stems without bogging down. Buyers who already own 18V ONE+ batteries should choose the RYOBI ONE+ HP 18V Brushless 22 in. Hedge Trimmer (P2690) instead, since it matches the same 5/8 in. cutting capacity on a lighter, already-owned battery platform. Only pick the gas-powered RY29551 if avoiding batteries entirely is a hard requirement.
