There’s a unique satisfaction that comes from a perfectly manicured hedge. It’s a quintessentially British sight, a neat line of green that brings order and beauty to our gardens, whether it’s a sprawling country estate or a tidy suburban plot in Milton Keynes. But behind every crisp edge and level top is a gardener, and more often than not, a trusty hedge trimmer. For years, that meant wrestling with tangled extension cords or faffing about with petrol and oil, enduring the noise and fumes just to get the job done.

Then came the cordless revolution, and brands like Makita stepped up. Makita, a name synonymous with quality and durability on building sites across the UK, turned its attention to the garden shed. The Makita DUH523Z 18V Cordless Hedge Trimmer is one of the results of that shift. It promises freedom from cables, less noise, and the same robust performance that professionals have relied on for decades.

But does it deliver? Is this the tool that will finally make hedge trimming less of a chore and more of a pleasure? This review isn’t just a quick once-over. We’re going deep. We’ll explore everything from its design and handling to its cutting power and battery life. We’ll see how it fares against the classic British hedges—from tough, woody laurel to delicate privet—and help you decide if it’s the right tool to tame the greenery in your garden. Think of this as the ultimate guide for any British gardener considering cutting the cord for good.

Unboxing the Beast: First Impressions and What’s in the Box

Let’s get one thing straight from the off: the ‘Z’ in DUH523Z is important. It stands for ‘body only’. When you buy this model, you’re getting the hedge trimmer itself, a blade cover, and the instruction manual. There is no battery or charger included.

This might seem a bit cheeky, but it’s actually one of Makita’s smartest moves. The DUH523Z is part of their huge LXT 18V battery platform. This means the same slide-on battery that powers your Makita drill, impact driver, or circular saw will also power this hedge trimmer. For anyone already invested in the Makita ecosystem—and that includes countless tradespeople and serious DIYers in Britain—this is fantastic news. You save money by not having to buy yet another battery and charger that will just clutter up the garage.

If you’re new to Makita, you’ll need to factor in the cost of a battery and charger. A 3.0Ah or 4.0Ah battery is a good starting point, offering a decent balance of runtime and weight.

First Feel and Build Quality

Picking up the DUH523Z, the first thing you notice is the trademark Makita quality. It feels solid and well-put-together, not flimsy or plasticky like some cheaper rivals. The iconic turquoise and black housing is made from a tough, durable polymer that can handle the odd knock and scrape. Nothing rattles or feels loose. It has a reassuring heft to it, weighing in at around 3.3 kg with a battery fitted. This isn’t the lightest trimmer on the market, but it’s balanced enough that it doesn’t feel unwieldy.

The design is straightforward and functional. There are no unnecessary gadgets or gimmicks. It’s a tool built to do a job, and do it well.

Core Concepts: Understanding What Makes the DUH523Z Tick

Before we get into the nitty-gritty of performance, let’s break down the key features of this machine. Understanding the technology behind it helps explain why it works so well.

The LXT Battery System: The Heart of the Machine

The core of any cordless tool is its battery, and Makita’s LXT (Lithium-Ion Xtreme Technology) system is one of the best in the business. Launched in 2005, it was one of the first 18V lithium-ion platforms from a major manufacturer, and it has set the standard ever since.

Here’s why it matters:

• Power and Efficiency: LXT batteries deliver consistent power, so the trimmer doesn’t start to slow down as the battery drains. It cuts just as well on 10% charge as it does on 100%.
• Fast Charging: Paired with a Makita fast charger, you can get a 3.0Ah battery from empty to full in around 22 minutes. That’s less time than it takes to have a proper cup of tea and a biscuit.
• Durability: These batteries are built to last, with internal electronics that protect against overheating, over-discharging, and overloading. They’re designed for the rough-and-tumble environment of a construction site, so they can certainly handle a bit of gardening.
• The One-Battery-Fits-All Dream: With over 275 tools in the LXT range, the battery you use for your hedge trimmer can also power everything from a lawnmower to a radio. It’s an ecosystem that grows with your needs.

The Blade: The Business End

The DUH523Z is fitted with a 52cm (or 20.5-inch) double-sided blade. This is a great all-round length for most domestic hedges in the UK, long enough to make quick work of a long run but short enough to remain manoeuvrable.

The blades themselves are a work of art. Makita has used a non-electrolysed nickel plating, which gives them a glittering silver finish. This isn’t just for looks. The coating is highly resistant to abrasion and helps prevent sap and resin from sticking, which means less cleaning and a cleaner cut.

A key feature is that the blade is user-replaceable. On many cheaper trimmers, if you damage the blade, the whole tool is a write-off. With the DUH523Z, you can simply unbolt the old blade and fit a new one without having to take the entire housing apart. This is a massive plus for long-term ownership.

Anti-Vibration Structure: Saving Your Arms

Anyone who has used a petrol hedge trimmer for an extended period will know about the dreaded arm fatigue caused by vibration. It can leave your hands buzzing for hours afterwards.

Makita has tackled this with an impressive anti-vibration structure. The motor and crank section are separated from the handles by five rubber cushions. These act like shock absorbers, soaking up the vibrations before they reach your hands. It makes a huge difference, allowing you to work for longer periods in much greater comfort. It’s one of those features you don’t notice until you use a tool without it, and then you can’t go back.

Safety Features: No Accidents in the Garden

Safety is paramount when you’re working with a tool that has sharp, fast-moving parts. The DUH523Z is packed with features to keep you safe.

• Two-Handed Operation: You can’t start this trimmer by accident. The motor will only engage when you’re holding the main handle and pressing the trigger, and pressing the switch on the front handle. As soon as you let go of either, the motor stops. This prevents it from starting up if you drop it or are carrying it one-handed.
• Electric Brake: The moment you release the trigger, an electric brake stops the blades almost instantly. They don’t wind down slowly, which significantly reduces the risk of accidental cuts.
• Battery Protection Circuit: This clever bit of tech protects the battery from damage. It will automatically cut power if the battery level gets too low or if the tool is being overloaded (for example, if you’re trying to cut a branch that’s just too thick). A warning lamp on the handle blinks to let you know the battery is low, and turns solid just before it cuts out.

Performance in the Field: How Does It Actually Cut?

Right, enough with the technical specs. Let’s get out in the garden. How does the Makita DUH523Z actually perform when faced with a real British hedge? We tested it on a few common varieties to see how it coped.

The Test Subjects:

1. Privet (Ligustrum ovalifolium): A classic British hedge. Fast-growing, with lots of thin, leafy stems. The challenge here is getting a clean, neat finish without chewing the leaves.
2. Yew (Taxus baccata): The king of formal hedges. Dense, fine foliage that demands a precise cut for those perfect topiary shapes.
3. Hawthorn (Crataegus monogyna): A tough, woody country hedge. Can have branches up to about 10-15mm thick. This is a test of raw cutting power.
4. Leylandii (Cupressus × leylandii): The infamous fast-growing conifer. Can get out of hand quickly, requiring a powerful tool to keep it in check.

The Verdict: Power, Precision, and Endurance

The DUH523Z delivers 1,350 strokes per minute. This might sound low compared to some mains-powered or petrol models, but don’t be fooled. The torque and the sharpness of the blades mean it slices through greenery with surprising ease.

• On Privet and Yew: The trimmer was in its element. It was light and manoeuvrable enough to create smooth, sweeping curves and sharp, straight lines. The blades are so sharp they give a very clean cut, which is healthier for the plant and reduces the browning of leaf edges you can get with blunter tools. It left a finish that a professional would be proud of.
• On Hawthorn: This is where the tool’s power became apparent. It happily chewed through branches up to about 15mm in diameter, which is its official maximum cutting capacity. You could feel the motor working, but it never felt strained. For the odd thicker branch, a quick second pass was sometimes needed, but it got the job done without any drama. It’s not going to replace a set of loppers or a chainsaw for hedge restoration, but for annual maintenance, it’s more than capable.
• On Leylandii: The long 52cm blade made quick work of trimming large, flat surfaces. The lack of a cord was a massive advantage here, as weaving in and out of a long conifer hedge can be a real pain with a cable snagging on every branch. The anti-vibration system really came into its own during this longer, more demanding job.

Battery Life: How Long Does It Last?

This is the million-dollar question for any cordless tool. The answer depends entirely on which battery you use and what you’re cutting.

• With a 3.0Ah battery: You can expect around 40-60 minutes of continuous runtime. This is enough to tackle a decent-sized garden hedge.
• With a 5.0Ah battery: You’re looking at 70-90 minutes or more. For most homeowners, this is more than enough to get all their hedges done on a single charge. One user even reported trimming for an hour and a half and only using one bar of a 5.0Ah battery.

The key takeaway is that for a tool of this power, the battery life is excellent. It’s a testament to the efficiency of the motor and the quality of the LXT batteries.

Noise Levels: Your Neighbours Will Thank You

One of the biggest advantages of battery power over petrol is the reduction in noise. The DUH523Z is incredibly quiet in operation. It produces a gentle whirring sound, a world away from the screaming two-stroke engine of a petrol trimmer.

You can comfortably use it on a Sunday morning without worrying about waking up the entire neighbourhood. You don’t need ear defenders, and you can still hear if someone calls your name. It makes the whole experience of trimming the hedges far more pleasant and civilised.

Living with the DUH523Z: Practicality and Ergonomics

A tool can have all the power in the world, but if it’s a nightmare to use, it will end up gathering dust in the shed. So, how does the Makita DUH523Z stack up in day-to-day use?

Weight and Balance

At 3.3kg, it’s not a featherweight, but the balance is superb. The weight is distributed evenly between the battery at the rear and the motor and blade at the front. This makes it feel lighter in the hands than the numbers suggest and reduces strain on your wrists and back.

It’s comfortable to use for both vertical cuts (the sides of the hedge) and horizontal cuts (the top). Even when reaching up high for the top of a tall hedge, it remains controllable. Several users have specifically praised how manageable it is when working off a ladder, where a cumbersome, poorly balanced tool can be genuinely dangerous.

Handling and Controls

The handles are coated in a soft, rubberised grip that is comfortable to hold and provides excellent control, even when your hands are a bit sweaty. The two-stage safety switch is intuitive and easy to operate, falling naturally under your fingers when you adopt a proper working stance.

The lack of a rotating rear handle is perhaps one of the only minor drawbacks. Some premium models have this feature, which makes switching between horizontal and vertical cutting a little more comfortable. However, given the DUH523Z’s excellent balance, it’s not a deal-breaker, especially at this price point.

Maintenance: Keeping It Sharp

Maintenance is refreshingly simple.

1. Cleaning: After each use, it’s good practice to wipe down the blades with a cloth and some lubricating spray (like WD-40 or a specialist resin remover). This stops sap from building up, which can blunt the blades and put a strain on the motor.
2. Sharpening: The blades will eventually need sharpening. This can be done carefully with a file, or you can take it to a local garden machinery specialist.
3. Blade Replacement: As mentioned, the blades are easy to replace. Simply undo a few bolts, slide the old set off, and put the new ones on. It’s a 10-minute job.

That’s it. No spark plugs to change, no fuel to mix, no air filters to clean. This is the low-maintenance joy of battery power.

Who is the Makita DUH523Z For?

This hedge trimmer hits a real sweet spot in the market. It’s perfect for:

• The Serious Home Gardener: If you take pride in your garden and want a tool that delivers a professional-quality finish without the hassle of petrol or cords, this is for you. It has enough power to handle almost any domestic hedge.
• Existing Makita Users: If you already own any Makita 18V LXT tools, buying this is a no-brainer. It’s an affordable way to add a high-quality hedge trimmer to your arsenal without investing in a new battery platform.
• Professional Gardeners and Landscapers: While Makita makes more powerful, professional-grade models, the DUH523Z is an excellent, lightweight option for lighter trimming duties and finishing work. Its low noise is also a huge benefit when working in residential areas.

It might be slight overkill if you only have a tiny box hedge to trim once a year, but for anyone with a substantial amount of hedging, it represents fantastic value.

The Verdict: A Modern Classic for the British Garden

The Makita DUH523Z 18V Cordless Hedge Trimmer is, without a doubt, a superb piece of kit. It perfectly balances power, performance, and practicality.

It’s powerful enough to tackle tough, woody growth, yet precise and light enough to create beautifully manicured formal hedges. The build quality is exactly what you’d expect from Makita—robust, durable, and designed to last for years. The anti-vibration system and low noise levels make it a genuinely pleasant tool to use.

The real genius, however, lies in the LXT battery system. The convenience of using one battery for a whole range of top-quality tools cannot be overstated. It simplifies your life, saves you money, and ensures you always have a charged battery ready to go.

Are there any downsides? Very few. The lack of a rotating handle is a minor point, and the initial investment in batteries and a charger might be a hurdle for those new to the Makita platform. But these are small quibbles in the face of such a capable and well-designed machine.

In a world full of flimsy, disposable tools, the Makita DUH523Z feels like an investment in quality. It’s a reliable, powerful, and easy-to-use trimmer that will help you keep your British garden looking its best for many seasons to come. It doesn’t just cut hedges; it cuts the hassle, the noise, and the cord, leaving you with nothing but a perfectly trimmed garden and a real sense of a job well done.
