Gtech cordless home and garden power tools are some of the best on the market, with the company producing premium quality lithium-ion batteries that has helped to cement their place in the cordless tool market.

Despite only recently releasing a range of cordless garden tools, Gtech are in the process of updating their current line-up, with one of the most exciting releases being the GT 3.0 cordless electric grass trimmer.

This new model is a replacement for Gtech’s very popular strimmer the GT20, and the company say that this new and improved model comes with some fantastic upgrades that make it even better than the original – but does the GT 3.0 live up to the hype?

Let’s take a look and see!

GT strimmer 3.0


  • 18V Lithium-Ion Battery
  • 30 Minute Runtime
  • 4 Hour Charge Time
  • Rotatable Cutting Head
  • Weighs 1.85kg


Cordless garden tools always need a great battery to function at their best. Without one, the tool won’t last for as long as you need, making it more hassle than its worth and not giving you the convenience that makes a cordless tool so appealing.

So, how good is the GT 3.0’s battery? Well, it’s the exact same as the GT20, which is somewhat disappointing because it means that there are not improvements in terms of runtime or charge time.

However, the news isn’t all bad because the 18V lithium-ion battery remains one of the best on the market, so it’s not necessarily a bad thing. Yes, it would be nice to have a little longer runtime but at 30 minutes it’s still longer than most other cordless trimmers!

In fact, when you consider the 30-minute runtime and four hour charge time, the GT 3.0 still has one of the top performing batteries of any cordless garden tool. 30 minutes is typically enough to trim away edges on most lawn sizes. 

Another cool aspect about the battery is that it is interchangeable with Gtech’s other cordless garden tool the HT 3.0. The HT 3.0 hedge trimmer uses the same 18V lithium-ion battery as this grass trimmer, so if you own both you basically double the runtime of each because you can use both batteries!

So, if you are looking for a new hedge trimmer and grass strimmer, it’s well worth considering the GT 3.0 and HT 3.0 as both have interchangeable batteries.

Cutting Head

The GT 3.0 takes a unique approach to its cutting head. Instead of using a spool of plastic wire, the standard cutting device for most strimmers, the GT 3.0 features a series of smaller plastic blades that are attached to the cutting head.

This easily clips onto the trimmer and offers a much more robust cutting device that won’t break on every hard surface like a cutting line tends to do. These are likely to break eventually, just far less often compared a spool.

Better still, you get 20 in a pack grass trimmerand they simply click into place, so there’s no need to fiddle around feeding through a line or changing spools. There are also replacement blades should you run out, with a pack of 50 costing less than a fiver.

These blades produce a very clean and precise cut and are far more durable than a trimmer line. As the blades are thicker too, it means you can tackle thick and longer grass without any fuss.

The cutting head is also adjustable, with a quick flip converting it from a grass trimmer into a lawn edger. This feature is amazing for getting precise edges done along the lawn where the mower often misses, so if you love a clean cut around the edge of lawns and borders then this will get the job done.


One of the GT 3.0’s biggest selling points is the fact that it is so easy to operate. Being a cordless trimmer means that it’s not restricted by any cord so you are free to use it anywhere in the garden, which is great news for anyone with larger outdoor areas.

Also, it’s arguably the lightest garden trimmer on the market, weighing an incredible 1.85kg! This makes the GT 3.0 so easy to operate, with it being lightweight enough where you are very unlikely to get tired or feel strained from using for too long.

This also brings us to the main upgrade of the GT 3.0 – the new and improved handle. The handle of the GT 20 lacked a secondary handle further down the trimmer, with the GT 3.0 adding a smaller handle part mid-way down the shaft.

With an extra handle the GT 3.0 becomes even easier to operate! The balance is much easier to maintain thanks to this extra handle, which in turn means more stability and precision when trimming, especially in tighter areas such as around a fence or at the base of a tree or bush. 

This also means there is less chance of feeling fatigued, which did happen with some GT20 owners as there is just a single handle and nothing else, another reason why this trimmer is the perfect option for older people and anyone that may struggle to operate heavier tools.

Final Thoughts

An excellent grass trimmer. It’s compact, lightweight, and comes with a redesigned handle that makes it simple to operate for most people, while the choice of plastic cutting blades over a traditional spool is a notable improvement over most competing devices. 

With a 30 minute runtime, it’s best saved for smaller gardens as the battery likely won’t last long enough for larger areas. That said, as the battery is interchangeable with the HT 3.0 hedge trimmer you can end up with two batteries for each device, effectively doubling the runtime on each.


  • Lightweight and easy to use
  • Adjustable cutting head for edging and trimming
  • Works great in and around tighter spaces
  • Plastic cutting blades much better than a spool


  • No battery upgrade although the battery is still very impressive
