The Ryobi RPT184520 is an 18V ONE+ cordless pole hedge trimmer designed for regular maintenance of tall and awkward hedges from ground level.
Its main strengths are the extended reach, articulating cutting head and cordless convenience. It’s also particularly appealing if you already own Ryobi ONE+ batteries.
There is a trade-off: like most pole hedge trimmers, it becomes noticeably heavier and less balanced when fully extended, and it isn’t designed for thick, woody or heavily neglected growth.
For regularly maintained tall hedges, though, the RPT184520 offers a practical way to keep growth under control without routinely reaching for a ladder.

What It Does Well

- Less powerful than heavier-duty alternatives
Bottom line: The Ryobi RPT184520 is a practical choice for keeping tall hedges tidy without routinely using a ladder. It works best as a regular maintenance tool rather than for heavy cutbacks or badly overgrown hedges.

How the Ryobi RPT184520 Performs
The Ryobi RPT184520 is at its best as a maintenance tool for tall hedges rather than a heavy-duty cutter. On regularly trimmed growth, its combination of reach, adjustable cutting angle and cordless operation makes it easy to understand where the tool earns its place.
Cutting Performance
The 45cm blade cuts fresh, green and regularly maintained hedge growth cleanly and predictably. It works particularly well for topping and tidying established hedges where the aim is to remove the current season’s growth rather than carry out a major cutback.
Performance drops noticeably on thicker, woody or neglected stems. For heavier growth, you’ll usually get better results by removing the thickest material with loppers or a more powerful hedge trimmer first.
The cutting action is steady rather than aggressive, which suits the kind of controlled trimming this tool is designed for.
Reach & Articulating Head
Reach is the RPT184520’s biggest advantage. Being able to work across tall hedge tops from ground level removes much of the need for ladders and awkward stretching with a standard hedge trimmer.
The articulating cutting head is particularly useful for this. Changing the blade angle makes it easier to work across hedge tops, vertical faces and awkward sections without forcing your arms or wrists into uncomfortable positions.
At full extension, some movement through the long pole becomes more noticeable and small inputs at the handle are amplified at the cutting head. Working steadily rather than rushing gives much better control.
Weight, Balance & Comfort
The main trade-off is weight distribution. Once the pole is extended and a ONE+ battery is fitted, the trimmer becomes noticeably top-heavy, especially when working above shoulder height.
That makes it much better suited to short, controlled trimming sessions than prolonged overhead use. Working along a hedge in sections and taking occasional breaks keeps fatigue manageable.
The mostly reinforced-plastic construction helps prevent the tool becoming unnecessarily heavy, while the handles and locking mechanisms feel appropriate for normal domestic use. It still feels like a home-garden tool rather than a professional all-day machine — which is consistent with its intended role.
For regular hedge maintenance, that balance of reach, manageable cutting performance and cordless convenience works well. If you need to tackle thick growth for long periods, however, a heavier-duty tool will be the better choice.
Battery & ONE+ Compatibility
The Ryobi RPT184520 uses Ryobi’s 18V ONE+ battery system, so battery choice affects both runtime and how the trimmer feels at full extension.
A smaller 2.0Ah battery keeps overall weight down and can make sense for short trimming sessions. For larger hedges, a 4.0Ah battery or similar offers longer runtime and reduces the need to stop and swap packs.
The trade-off is weight. Because the RPT184520 is already noticeably top-heavy when extended, fitting a larger battery adds further weight at the handle. There is therefore a useful balance between runtime and comfort, rather than one battery size being automatically best for everyone.
For gardeners who already own Ryobi cordless tools, ONE+ compatibility is one of the RPT184520’s strongest practical advantages. Existing batteries and chargers can be shared across the system, potentially making the trimmer considerably cheaper and easier to add to your existing setup.
How It Compares to Other Hedge Trimmers
The Ryobi RPT184520 makes most sense when reach and cordless convenience matter more than outright cutting power. Compared with other hedge-trimming options, the trade-offs are fairly simple:
| Option | Better when… |
|---|---|
| Ryobi RPT184520 | You need to maintain tall hedge tops from ground level |
| Standard cordless hedge trimmer | Most cutting is at normal height and comfort matters more than reach |
| Manual/telescopic shears | You only have occasional light trimming to do |
| Corded pole hedge trimmer | You want continuous power and don’t mind managing a cable |
| Petrol / heavy-duty trimmer | You regularly tackle thick, woody or neglected growth |
For regularly maintained tall hedges, the Ryobi offers a useful middle ground: much easier reach than a standard hedge trimmer, without the noise, maintenance or weight of heavier petrol equipment.

Who Should Buy the Ryobi RPT184520?
The Ryobi RPT184520 is best suited to home gardeners who need extra reach for regularly maintained tall hedges, particularly where working from a ladder is awkward or undesirable.
Buy It If
- You regularly trim tall or established hedges
- You want to work from ground level
- Your hedges are maintained little and often
- You mainly need help with hedge tops and awkward sections
- You’re comfortable working in short, controlled sessions
- You already use the Ryobi ONE+ 18V system
Look Elsewhere If
- You need to cut thick, woody or heavily neglected growth
- You want a tool for long, uninterrupted hedge-cutting sessions
- You dislike the feel of top-heavy long-reach tools
- Most of your hedges are low enough for a standard cordless hedge trimmer
- You’re starting a new battery platform and another kit offers better overall value
For the right garden, the RPT184520 works best as a specialist reach tool rather than your only hedge trimmer. A standard cordless hedge trimmer will usually remain more comfortable for lower hedge faces, while the Ryobi handles the tops and harder-to-reach sections.
FAQs
It is best suited to regularly maintained light to medium hedge growth. It will handle fresh seasonal growth well, but thick, woody or heavily neglected stems are better tackled with loppers or a more powerful hedge trimmer.
A 2.0Ah ONE+ battery can work well for short trimming sessions and keeps overall weight down. For larger hedges, a 4.0Ah battery or similar offers longer runtime, although the extra battery weight becomes more noticeable when the pole is fully extended.
It depends on the package. Many listings sell the RPT184520 as a bare tool without a battery or charger, while some retailers may offer it as part of a kit. Check exactly what is included before buying.
For most gardens, not completely. The RPT184520 is particularly useful for hedge tops and hard-to-reach sections, while a standard cordless hedge trimmer is usually lighter and more comfortable for lower sides and longer periods of cutting.
For many gardeners, the two tools work best alongside each other rather than as direct replacements.
Final Verdict
The Ryobi RPT184520 is a practical cordless pole hedge trimmer for gardeners who regularly maintain tall or hard-to-reach hedges.
Its biggest strengths are the excellent reach, useful articulating cutting head and compatibility with the Ryobi ONE+ 18V system. It makes topping and tidying maintained hedges considerably easier without routinely relying on a ladder.
The main compromise is weight. It becomes noticeably top-heavy when extended and is better suited to short, controlled sessions than prolonged cutting. It also isn’t designed for thick, woody or heavily neglected growth.
For regular domestic hedge maintenance, though, it does its intended job well and is particularly easy to recommend to existing ONE+ users.
