How we chose
We assessed current Australian exact models, availability, street prices, kit-versus-skin inclusions, battery ecosystems, cutting width, line diameter, motor and feed systems, balance, owner evidence, professional testing, warranty, service and value. Worth Buying Australia did not physically laboratory-test these trimmers.
Serious contenders reassessed
Husqvarna 215iL: a credible lightweight premium kit, but its 31cm cut, included 2Ah battery and $539 price make its value less compelling. AEG: strong current owner pools, though fragmented model and kit naming produces a less straightforward general recommendation.
Makita: remains sensible for committed LXT owners, but overlapping SKUs and higher kit costs complicate the mainstream case. DeWalt 54V: powerful, but the current Australian kit had a tiny mixed owner sample. Ozito: cheaper options exist, while current higher-powered feedback is more mixed. The RYOBI R18HLTR14/R18HLTR38 remains a capable middle ground between the two selected RYOBI kits.
RYOBI 36V HP Brushless Whisper 38/43cm Line Trimmer 6Ah Kit R36XLTR26

The R36XLTR26 combines a 36V HP brushless motor, a 38/43cm adjustable cutting path and 2.4mm line. The bottom-mounted motor and wide swath make it meaningfully more capable than small edging-focused 18V machines. Two speeds and a variable trigger let the operator trade outright cutting pace for control and battery use.
The $599 kit includes a 6Ah battery and 4A charger. The Reel-Easy Speedwinder head helps with reloading, but line advancement remains conventional bump feed. This is a line trimmer, not a brushcutter: the supplied evidence does not support metal-blade compatibility.
At 4.2kg before the battery, it is substantial. A 6Ah pack adds more rear weight, no harness is supplied and the loop-handle layout may fatigue some users on long sessions. Its 92.4dB(A) stated LWA also shows that cordless does not mean silent.
What owners say
Pros
- Wide 38/43cm cut and 2.4mm line
- HP brushless motor with variable control
- Large 6Ah battery in the complete kit
- Strong Australian retailer evidence
- Broad RYOBI 36V garden ecosystem
Cons
- Costs $599
- 4.2kg before adding the battery
- No harness supplied
- Bump feed still needs physical activation
- Not a brushcutter and no metal-blade claim
RYOBI 18V ONE+ 25/30cm Line Trimmer 4Ah Kit R18LTR24

The R18LTR24 kit uses the OLT1832 trimmer with a 4Ah ONE+ battery and 2A charger. Its 25/30cm adjustable cut, 2.0mm line, telescopic shaft, three-position head and rotating edging layout cover routine work along fences, beds and paths. At 2.4kg, the tool is much easier to handle than the 36V overall pick.
Auto feed avoids bumping the head, although repeated trigger cycling can consume line faster. The brushed motor, one-speed control and narrower swath also set realistic limits: this is for maintained suburban edges, not acreage or thigh-high weeds.
RYOBI claims up to 42 minutes with the 4Ah battery under no-load conditions. That must not be read as 42 minutes of demanding real-world trimming; dense kikuyu or buffalo edges and continuous full-width cutting can reduce working time materially.
What owners say
Pros
- $179 complete-kit value at research date
- Light 2.4kg tool
- Telescopic shaft and adjustable head
- Auto feed and edging capability
- Extensive Australian exact-model evidence
Cons
- Brushed motor and one speed
- Narrower 30cm maximum cut
- Less capable in dense or long grass
- Auto feed can use extra line with repeated trigger cycling
- Not Expand-It or brushcutter hardware
What matters when buying a cordless line trimmer
Line trimmer or brushcutter?
A line trimmer is primarily for grass, lawn edges and soft weeds. A brushcutter is designed for tougher vegetation and may accept metal blades. Do not assume a cordless whipper snipper supports blades unless the exact manufacturer specification says it does.
Cutting width and line
About 25–30cm suits small yards and edging; 33–38cm covers general suburban work; 40cm or more clears open areas faster. Wider cuts can draw more energy and reduce precision. A common 2.0mm line handles residential edging, while 2.4mm better resists heavier grass. Never exceed the supported line diameter.
Feed systems are different
Auto feed releases line through trigger or head behaviour. Bump feed requires tapping the head. Powerload winds replacement line into the spool; it is not the same as Line IQ, which automatically maintains line length during work.
Voltage is not a score
Voltage can indicate power potential, but motor design, line, head, cutting width, battery energy and control also matter. A 56V machine is not automatically the better purchase than a 36V or 18V tool for every yard.
Battery capacity and kits
Within the same platform, more amp-hours generally means more stored energy. Across different voltages, Ah alone is not directly comparable. Always check whether the price is for a skin or a kit: the EGO tool-only and complete-kit configurations differ by battery and charger.
Weight and balance
A line trimmer is held away from the body, so head weight, battery size, shaft length and handle placement become tiring over time. A heavy high-power machine may benefit from a compatible harness, but no harness is supplied with the RYOBI overall pick.
Australian grass conditions
Buffalo and kikuyu edges can become demanding when wet, dense or overgrown. Small 18V tools remain useful on maintained edges, but should not be represented as acreage-clearing brushcutters.
Runtime varies in use
Cutting width, speed, grass density, line length, battery age and load all affect runtime. Manufacturer no-load or controlled-condition figures are useful context, not promises for continuous work in thick growth.
Which one should you buy?
Choose the RYOBI R36XLTR26 for the strongest all-round balance of cutting capability, complete-kit value and Australian exact-model evidence.
Choose the RYOBI R18LTR24 for ordinary small-to-medium yards when low cost and light handling matter most.
Choose the EGO ST1620E-T / ST1624E-T when Powerload and Line IQ justify a premium, remembering that $429 is tool-only and $749 is the complete kit.
Frequently asked questions
Is an 18V line trimmer powerful enough?
For a maintained small-to-medium yard, ordinary edging and soft weeds, a well-matched 18V trimmer can be enough. Dense, wet or badly overgrown buffalo and kikuyu expose the limits of a narrow, lower-powered machine much sooner.
Is a 36V or 56V line trimmer better?
Neither voltage wins automatically. Compare the motor, cut, line, head, included battery, balance, evidence and complete-system price. The right answer depends on the work and batteries you already own.
What line thickness should I use?
Use only a diameter supported by the exact model. Around 2.0mm is common for maintained residential grass; 2.4mm is tougher for heavier growth but should not be fitted to a head that is not designed for it.
Is bump feed or automatic line feed better?
Auto feed is convenient for routine work but can use extra line depending on trigger behaviour. Bump feed gives the operator more control but requires tapping the head. Powerload handles reloading, while Line IQ automatically maintains working length.
Can a cordless line trimmer replace a petrol whipper snipper?
A powerful cordless model can replace petrol for many maintained residential lawns. It should not be presented as a universal substitute for blade-equipped brushcutters, acreage clearing or severely overgrown vegetation.
