Greenworks GD24HT56K2 Hedge Trimmer Review UK – Tested and Rated

The Greenworks GD24HT56K2 is the budget pick in our cordless hedge trimmer comparison – the cheapest model tested with battery and charger in the box. For that price it delivers something specific and real: the ability to trim a small, soft, frequently maintained domestic hedge without a power cable, without spending significantly more, and without any technical knowledge about battery platforms or tool ecosystems. For the very narrow use case it suits, it does the job. Anything outside that narrow case and the Greenworks shows its limitations clearly and consistently.

Greenworks is a Chinese-owned brand that has grown its UK market presence steadily over the past five years by undercutting established names on price. Their garden tool range spans lawn mowers, leaf blowers, chainsaws and hedge trimmers across 24V and 40V platforms. The 24V range is the entry-level tier, and the GD24HT56K2 is its hedge trimmer representative. Unlike Ryobi’s ONE+ or Makita’s 18V LXT – both of which have 100+ compatible tools in their ecosystems – the Greenworks 24V range is narrower in scope and less widely stocked in UK hardware retailers. This platform limitation is a genuine consideration for buyers who view the battery as a long-term investment rather than a single-tool purchase.

Overview and first impressions

The GD24HT56K2 arrives in a compact box with the trimmer, blade guard, 2Ah 24V battery and charger included – a complete kit requiring nothing further to get started. First impressions are mixed rather than straightforwardly positive. The 56cm blade is the longest in the budget portion of our test field and its length is immediately apparent – a genuine positive on wide hedges where coverage per stroke matters. The battery clicks in securely and the tool starts cleanly. These are the highlights of the unboxing experience.

The counterpoint arrives the moment the tool is held and handled. The plastic housing is noticeably lighter and less substantial than even the Ryobi RHT1851R20 at a similar price point, and the internal quality impression – the feel of the handle materials, the action of the trigger mechanism, the rigidity of the blade assembly – falls short of the confidence that the Bosch or Makita inspires. This is not a manufacturing defect; it is an accurate reflection of what the entry price delivers versus the mid-range alternatives. The quality is proportionate to the price, and the price is genuinely low.

Balance is poor by the standards of the other trimmers in our test. The blade end sits noticeably heavier than the motor housing end, requiring the leading hand to provide active upward support throughout every cutting stroke to hold the blade level. This is tiring over a sustained session in a way that the Makita’s exceptional balance or the Bosch’s centred weight distribution is not. On a five-minute trim of a small hedge it is a non-issue. On a 20-minute session across multiple hedge sections it accumulates into genuine forearm fatigue – particularly relevant given that 20 minutes is approaching the total battery runtime in any case.

Vibration is the most immediately distinctive characteristic in hand and the most significant ergonomic limitation of this tool. From the moment the blade begins running, both handles transmit vibration at a level perceptibly higher than any other trimmer in our test. On soft new growth where the blades pass through with minimal resistance this is noticeable but manageable. On anything approaching the rated cutting limits – where the motor is working at full load – the vibration level is uncomfortable without thick gloves and becomes genuinely unpleasant during sustained cutting. Wearing gloves is not optional with this tool; it is practically mandatory for any session beyond a few minutes.

Specifications and scores

How it performed in our tests

Testing used the same 15-metre mixed privet, hawthorn and box hedge run used across all five trimmers in our comparison. On the soft new season privet growth that forms the majority of domestic hedge trimming in a regularly maintained garden, the GD24HT56K2 performed adequately. Cutting speed averaged 3.0 metres per minute – the lowest of any trimmer in our test but not dramatically so on easy growth, and the 56cm blade length partially compensates for the lower cutting speed by covering more hedge per stroke than shorter-bladed alternatives. Stems up to 10-12mm were cut cleanly and consistently without the motor showing stress.

The 14mm rated maximum is where the honest analysis becomes necessary. In practice the Greenworks approaches this limit much less comfortably than the rating suggests. Stems of 13-14mm caused audible motor strain, noticeable blade speed reduction and required two passes on the majority of mature hawthorn growth in our test. The 14mm figure is the rated limit, not a comfortable operating range – the Greenworks is genuinely at ease only on stems up to about 10-11mm, which means new season growth on a regularly clipped hedge is its natural domain. Any hedge that has been left for more than a season without trimming, or any hedge with inherently woody growth like hawthorn, will quickly expose the motor’s limits.

Vibration during cutting is the most significant practical issue identified in our testing and the one that most clearly distinguishes the Greenworks from the Ryobi at a similar price point. At 3.0 metres per minute on soft growth the vibration level is noticeable but manageable with gloves. At full motor load on tougher stems it is genuinely uncomfortable – a harsh, high-frequency buzz that transmits through both handles and becomes unpleasant within 10-15 minutes without protective gloves. The Ryobi RHT1851R20’s anti-vibration front handle – a component the Greenworks lacks – makes a measurable real-world difference that becomes apparent immediately when switching between the two tools. This is not a marginal specification difference; it is a comfort difference felt in the hands within minutes of use.

Cut finish quality on privet was moderate – adequate for a working hedge but noticeably less precise than the 19mm-spaced Ryobi or the 16mm Bosch. The 20mm tooth spacing is appropriate for the power level available and the growth the tool handles best, but it leaves more frayed stem ends than fine-spaced alternatives and produces a rougher visual finish on close inspection. For a hedge trimmed for appearance rather than just containment – a formal privet or box – the finish produced by the Greenworks would not satisfy in the way that the Bosch or Makita does. For a working boundary hedge where the goal is containment rather than presentation, the finish is acceptable.

Battery system and runtime

The Greenworks G24 24V battery system is the platform on which this trimmer sits, and it is honest to be clear about its scope relative to the alternatives. The G24 range includes a selection of garden tools – lawn mowers, leaf blowers, chainsaws and this trimmer among them – but the range is significantly smaller than Ryobi’s ONE+ or Makita’s LXT, and G24 batteries are less universally stocked than either of those platforms in UK hardware retailers. This is relevant because the battery cost represents a meaningful portion of the total tool cost at this price point – and a battery whose platform has limited scope and availability is worth proportionately less as a long-term investment than one sitting in a large, well-supported ecosystem.

Battery runtime from the included 2Ah battery was 28 minutes in our test – slightly better than the Ryobi’s 24 minutes, which reflects the lower power demands of the Greenworks motor drawing less current from the same capacity cell. At 28 minutes the single battery is adequate for a small hedge session. A 4Ah G24 battery is available and extends runtime to approximately 55 minutes, but the pricing of G24 batteries relative to the total tool cost makes the upgrade economics less compelling than with more mainstream platforms. In the vast majority of cases where the GD24HT56K2 is the right tool, the hedge it is being used on is small enough that 28 minutes is sufficient.

Performance, limitations and final verdict

The Greenworks GD24HT56K2’s limitations are not hidden or ambiguous – they are immediately apparent in use and consistently present across every area of performance beyond its one genuine strength, which is cutting soft new season growth on a small, regularly maintained hedge. Vibration is the highest in our test. Cutting power beyond 10-11mm of comfortable stem diameter is limited. Build quality is the lowest in the comparison. Balance is the poorest. The battery platform is the narrowest in scope. These are not surprising findings for the cheapest tool in the comparison with a battery included – they are the accurate profile of what the entry price delivers.

The value verdict requires honest separation of the buying situations where this tool is appropriate from those where it is not. For a gardener with a small, soft, city or suburban hedge – think a neat privet front boundary up to about 10 metres long, clipped several times a year – the Greenworks does the job. The 56cm blade covers reasonable ground per stroke, the 28-minute runtime is enough, and the cutting power on regularly maintained growth is adequate. The fact that the vibration is higher than on more expensive tools, that the build feels cheaper, and that the platform has limited expansion potential are all real but not disqualifying for this specific use case. A working result is what is being purchased, and working results are what the Greenworks delivers on the narrow scenario it suits.

For any buying situation outside that narrow case – a hedge with any established woody growth, a hedge that is trimmed infrequently, a tall hedge requiring overhead work, or a buyer planning to invest in a broader cordless tool collection – the Greenworks is not the right choice. The Ryobi RHT1851R20, available at a modest premium, is a meaningfully better tool in every measurable way: better vibration management, better cutting power headroom, better build quality, and a battery platform with 100+ compatible tools. The price difference between these two tools is real but the performance and platform difference is disproportionately larger than that gap suggests. Anyone who can stretch to the Ryobi should.
