Incredibly lightweight, the Gtech GT50 is a garden tool built with small green spaces in mind. If you hate re-stringing a grass trimmer, you’ll love the plastic blades, but they don’t last for long if you hit anything harder than grass.

Introduction
A small and lightweight grass trimmer that feels right for a small garden, the Gtech GT50 is cordless and ready for action. And you don’t need to worry about fiddly trimming wire either, this little machine is blades only.
For compactness and simplicity, then, this trimmer scores highly, but it’s a little lightweight when it comes to the cut and is suitable for the smallest areas only.
Design and Features
- Lightweight at under 2kg
- Plastic blades rather than string line
- Slow charging
Similar to the company’s other garden tools, such as the GTech LHT50, the GT50 is a super-lightweight tool that breaks down easily for storage.
It comes with a handy shoulder strap, something that is often missed out in my experience. If you’re the right height you can adjust the strap to let it take the weight of the trimmer. This allows you to concentrate on trimming rather than on the heft of the device.
Not that there’s much weight to this trimmer anyway. Coming in at an unbelievably light 1.85 kg, it’s a long way from heavy trimmers like the DeWalt DCMST561’s sizeable 3.5 kg.
It’s quite reasonably priced at £149.99, especially seeing as you get a battery and charger included.
The rear handle fits nicely in the hand, with a curved grip and ambidextrous safety switch. The front handle is less useful though, as it lacks the “D” shape of other trimmers that allows you to angle the cutting head easily.
Making things a bit easier, the cutting head can be adjusted to almost any angle by pressing the big green button. To switch to lawn edging mode, the entire cutting head can be rotated by 180° so that the blades point towards the grass like a windmill.
Gtech’s GT50 also does away with trimming string altogether. Instead, it chops through grass and other bits of undergrowth with a single small plastic blade. This flexible piece makes light work of grass and is the ideal solution for anyone who hates re-stringing a lawn trimmer.
The trimmer is bundled with 20 of these green blades that just snap into place under the cutting head. Spares are available via Gtech, and they’re pretty inexpensive at £3.99 for 50. The downside is that your cutting width is rather smaller than a lot of other devices. At just 23cm it will take much longer to trim a lawn to perfection.
The GT50 is similar to the Stihl FSA 45, although Stihl’s trimmer takes two blades to speed up cutting.
When it comes to storage, the GT50 is a dream for anyone lacking in shed space. The shaft comes apart and the cutting head and shield both come off, allowing you to tuck it away in a cupboard quite easily.
The trimmer comes with a 2.0Ah 18V Lithium-Ion battery that promises up to 30 minutes of trimming per charge. That’s plenty of working time for a smaller garden. And you can keep an eye on the charge level via the handy LED lights that surround the power button.
However, the four-hour charging time is a bit on the slow side. It’s fine if the edging and trimming gets done within half an hour, but otherwise it would be better to have another one on standby.
Performance
- Shoulder strap is comfortable
- Cutting head rotates for edging
- Blades break too easily
To test this trimmer out, I used it in a couple of test gardens that had overgrown grass and lots of weeds at the edges.
Something I really appreciate about this trimmer is the shoulder harness. Even though it barely weighs anything, allowing my shoulder to take the strain helped with comfort and accuracy. It’s another feature of this trimmer that makes me think it’s ideal for less-able users to keep their greenery in trim.
It’s a shame that I couldn’t adjust the handle length. Users over six foot tall like me will find themselves leaning forward to reach the surface of the lawn.
Instead of re-stringing this trimmer with fiddly line, you simply clip a new blade on like hanging a picture. There’s a keyhole shaped cut-out in each blade that fits neatly onto a post in the cutting head.
The main drawback of this trimmer, from my experience, is that it uses just a single plastic blade to do all the cutting. I ended up going through several after hitting stones in the grass and a concrete fence post. The blades seem rather too brittle for the job. It’s a shame that they seem to break as soon as they hit anything harder than blades of grass, and the Stihl FSA 45 seems to have tougher blades.
Compared with the wide cut swathe that the Stihl FSA 70 R produces, the GT50 feels a bit small. The tiny 23cm cut width means I was standing in each spot for longer trying to get an even finish on grass and weeds.
Being able to fine tune both the angle of the cutting head and turn it through 180° for edging was useful. It made edging comfortable and a little more accurate.
Overall, I would recommend this edge trimmer to someone who has a small patch of green to keep tidy. It does a good job on grass, and they can buy the body-only version of the SLM50 lawn mower and reuse the trimmer’s handle and battery, making for a good-value pair for tiny gardens.
Should you buy it?
You should buy if you have a small patch of grass
If you have a small patch of grass you want to keep tidy and you have minimal space for storage, this trimmer is great because it breaks down small and can be stored in a cupboard.
You should not buy if you have plenty of grass to trim
The small cut width and slow battery charge time make this only suitable for small jobs. You also might find this trimmer a bit small if you’re tall.
Final Thoughts
The Gtech GT50 is an ultra-light and easy-to-store grass trimmer well suited to smaller gardens. It’s great for anyone who hates the idea of re-stringing their trimmer, but the single plastic blades are rather fragile. For fans of compatibility, though, combining the GT50’s handle with the SLM50 mower body makes a neat space-saving combo.
