Cordless freedom in Gtech Hedge Trimmer

The assembly is very easy. The main body of the trimmer fits straight into the hole of trimmer handle which has the trigger. You now have to attach the battery to the trimmer handle. That’s it, you are good to go now. The trimmer head can also be rotated as per your requirement and when not in use fit the safety cover to protect the teeth from any kind of damage.

To start the trimmer you first have to press the safety switch to unlock the trigger. It is an added mechanism to prevent accidental trigger press. Now remove the safety cover from the trigger and press the battery indicator button to get an idea of how much battery you have. Just press the trigger button now and the trimmer will start working. To cut it from an angle just rotate the trigger head as per the need and that’s it. The assembly is very simple and can be done within 5 minutes.

What we liked about the Gtech HT20

The Gtech HT20 has a very durable construction. The body is made from good quality plastic and the rest of the construction is completely stainless steel. This makes the Hedge Trimmer very durable. It’s been a quite sometimes since the product was launched but even till now it doesn’t require any major upgrade.

The product is very long-lasting and that’s the main reason why most of the customers like it including me. The main unit is around 2 meters long and is very well balanced across the unit. This doesn’t make pressure on you as you need to hold the unit for quite long to finish the work.

You can cut through thick branches with ease. The teeth or the blades used here is also made from high-quality steel so when you are cutting through thick branches the blade won’t break or bend easily. This makes it very durable. The blade has a 31 cm length and has 1.5 cm spacing between each teeth. If you want to replace the teeth or the blade you can buy a replacement directly from the Gtech or just sharpen them whenever you want. I recommend you to keep the trimmer sharp always so won’t have any problem at all.

The Gtech HT20 Hedge Trimmer has an adjustable head and I personally like this feature more. This makes it easy to reach hedges and bushes which are high up the ground or at a boundary or wall. Now you don’t have to carry out your ladder every time just to cut the high hedge tops. The head angle can be adjusted from a range of 135 Degrees so you can just stand on the ground and cut the hedge tops straight which are located high above or just sweep through the ones which are high and flat. The versatility of the Gtech HT20 Hedge Trimmer saves you a lot of time and effort.

The best thing about this Hedge Trimmer is you can convert this into a branch Cutter. You have an option to purchase a separate branch cutter attachment for the Gtech HT20 Hedge Trimmer. The normal trimmer is still good enough for thin branches but when it comes to thicker branches the Optional Branch Cutter makes the work pretty simple. The extension pole and the 135 Degrees rotating trimmer head makes the work really simple.

The Branch Cutter and the pole are not included in the package by default but you can buy it separately. The branch butter can easily cut through a branch which has 15 mm to 25 mm thickness in our usage but as per Gtech it is capable of cutting a branch which is 40 mm thick but still, you can a branch of 6mm easily with this branch cutter.

The extension pole which Gtech offers can be used to make the trimmer even longer. Though it comes with a price tag of £40 it’s still worth it. This comes in handy when you have a very long hedge and don’t want to use a ladder. With this optional extension pole, you can extend the reach of the HT20 hedge trimmer for an extra 50 cm which is great. The trimmer is a completely cordless device and is powered by a Lithium-Ion Battery.

It doesn’t require petrol like the other trimmers which is a great thing in my opinion. It has an 18 V lithium-ion battery of 2000 mAh capacity which is great. The trimmer runs for about 45 mins in a single charge. The charging time here is about 4 hours. You also have a battery indicator here so you can easily check on how much charge you have left and additional you can buy spare batteries separately.

What we didn’t liked about the Gtech HT20

There is not a lot to dislike about this Gtech Hedge Trimmer. Let me tell you, this the best value for money trimmer you can get. Other trimmers in the market will cost you double of what Gtech is offering. Here are a few things which one should know before making the buying decision.

Some people complained that this trimmer is very heavy to use. The weight is around 2.25 Kg which are lightweight in my opinion but for extensive use, it may feel a bit heavy. The battery here also takes quite a long time to charge. It doesn’t come with a fast charger and the total charging time it takes to charge the hedge trimmer completely from 0 to 100% is around 4 hours which is quite long. You can also buy spare batteries if you want and charge them alongside and use the trimmer for a longer period of time.

You have to buy additional attachments along with the trimmer such as the Extension pole and the Branch cutter which will later add up to the price. Another thing here is the main unit is kind of small and not suitable to cut a very thick branch which has grown up over time. For that, you have to buy the optional Branch Cutter which will cost you a few extra bucks.

  • Completely cordless and ease of usability makes this device a perfect gardening tool.
  • Great build quality and high precision blades can cut up to 15 mm thick branches.
  • It runs on a Lithium-ion battery which gives a total run time of 45 minutes. Batteries can also be interchanged.
  • The Hedge trimmer is lightweight and weighs around 2.25 kg.
  • Has a double sided blade to ensure perfect cuts.
  • The main trimming head can be rotated up to an angle of 135 degrees allowing you more room to cut hedges which are located high without using a ladder.
  • Comes with an optional interchangeable Branch cutter head.
  • Comes with an option Extension Pole to extend the reach.
  • Features 2 years warranty from Gtech.
  • 30 Days money back guarantee.
  • Not suitable for very thick branches. You have to buy a branch cutter separately.
  • Additional accessories have to be bought separately which adds up to the price.
  • No fast charger included and the battery takes a massive 4 hours to fully charge.
  • Quite heavy for some people.

Final Conclusion

So this was a short review of the Gtech HT20 Hedge Trimmer. HT20 is one of our favorite gardening tools. It is also one of the most popular among customers. This makes the task very easier so you can do it yourself and no need to call a specialist. This saves you a lot of bucks in the long run. I won’t think twice before recommending this product.

      That’s a great decision, Joe, However I am not sure about the exact weight but I can tell it should be less than 4Kgs.

      It is always recommended to clean the blade after each use however you can do it at your convenience.

    I bought a gtech HT20 hedge trimmer a year ago to use when cutting my mother’s 50 yard privet hedge. The cutter is excellent
    in that there is no wire to worry about, and easy to wield and angle the head and reduces the time needed to do the cut. HOWEVER: I burst out laughing reading your review when you praise the tools durability. None of the branches in the privet are more then a few mm, yet even though I lubricate the blades periodically as I cut, the blades become quickly blunted, the motor in the head drives a cog wheel to drive the blades and this wears out with alarming rapidity and in the year I’ve had it I’ve had 4 replacement blades and 3 motor heads. The branch cutter is rubbish and simply not fit for purpose, there is not enough power in the head to cut through branches thicker than a few millimetres. It’s a shame as I like the ease of use but the HT20 is not up to the job as a durable tool. Maybe the HT30 is a better product. And as for the GTech vacuum cleaner I purchased, the head and motor have already had to be replaced in the first 6 months of light usage. Avoid.

      I have just purchase yet another HT20 Hedge Cutter Blade Assembly

      I did a post mortem on the unserviceable blades an found there seems to be an inherent fault with the drive mechanism of these blades.
      These drive cogs (I don’t know what you call these) seem to shatter when jamming on a twig too thick for the machine to handle. The design of this blade assembly should allow for such a mishap to be fixed with an easily replaceable part instead of being written off entirely, .I have written to Gtech and they said they were sorry I was unhappy with the product. They did not seem to care about my findings, I mean two blades with cogs broken in the same place. I think if the blade assembly had a torqued drive like a drill/driver it would stop the cogs from shattering.
      I would imagine I am not alone with this problem.

    Had two HT20’s one being a replacement from GTEC. Even though hedges had been previously been trimmed so growth was not too excessive, both head motor shafts snapped on examination shafts were unbelievably thin and not man enough for several seasons use.
    Disappointed, after first impressions I thought I had found the ideal tool for the job.

    How do you oil/clean the blades on the hedge trimmer? I’ve just had to buy a new blade as the old one was all gunged up with the sap off a privet hedge. I can scrape some of the gunge off but do I need to dismantle the blades to clean and oil and if so, what with?

    buy a proper resin remover and lubrication spray from a reputable dealer. All blades will have resin build up which cause more drain on the battery and affect the efficiency of the blade, I use Stihl Superclean, it’s not cheap but you only need a light spray. WD 40 will not do the same job.

    Like my namesake above I have found the HT20 to have been very unreliable. The branch cutter was a JOKE, very poor design that deposited the sawdust in the teeth of the blade which then quickly jammed, cleaning every two or three minutes helped a bit but it eventually broke the teeth. Replacement cutter also failed with same fault after less than five minutes of use
    The main on/off switch then failed and all Gtech could offer was a replacement lower unit at around £30 cost as the existing was not repairable. With nothing to lose I managed to replace the switch at a cost of £2.00 and an hour of my time
    Now the unit blade has started jamming despite being kept clean and well maintained and only being used on two weeks privet growth, all in all it has been the worst garden power tool we have ever bought and id definitely not recommended. Flimsy and poor build quality, better ones are available at almost half the cost
    The machine had only ever had very light occasional use as I have a more heavy duty one that just keeps on working. The Gtech one was bought for my wife to use as she found our existing one too heavy, I do the main cutting and she has used the Gtech just for light trimming and tidying.

    I have been working one of these for the last couple of years and have lots of hedges around my property, also on the allotment. I can only come to the conclusion that Philip and Phil are very heavy handed and make the same mistake as people on the allotments make going to hard and fast, slow down and the machine works fine

    Hi Amelia

    In general I agree with your review, except it might need to be updated.

    I bought my hedge trimmer from GTech five years ago, when it was new to the market, and just recently the blades have stopped working. I have changed the trimmer head and it works again, but it now jams continually. It is the same hedge and the same thickness of branches and the same general springiness of sprigs but whereas with the old blade it jammed perhaps once or twice a session, it now jams every thirty seconds. Usually I have to take the head off and manually push the plastic cog around to get it back in motion.

    I have thrown out the old head, sadly, because I would have liked to have seen if there was a different design. I note what some of your correspondents have said about the flimsy plastic cog, and whether, in order to preserve the cog, the manufacturer has changed the blade so it jams more easily, thereby preserving the cog?

    Just a thought

    I had delivery of a Gtech HT50 hedge trimmer on 15th Sept 2021 & after 2 to 3 minutes of use while lightly trimming a privet bush the cutters stopped but the motor was still running. I received a replacement trimmer from Gtech on 21st Sept 2021 & again while starting to trim the same bush again I had exactly the same problem. The branches on the bush are 2 to 3 mm thick so this well within the limits of what the machine has been designed for. I generally rate Gtech products very highly & the customer reviews for this product have been very positive. For this reason I am holding back on submitting a full product review as I am hoping that the problems I have had are down to issues with a certain production batch. Gtech in Worcester have advised that they will get back to me with their results of the cause of the failure that they are investigating & that they will send me a 3rd replacement mid October. I really hope that I don’t have a repeat of the same problem & that I can then post an in depth product review hopefully confirming that the product is actually fit for the purpose of use that Gtech are claiming.

    Also at a show I visited the Gtec stand and queried why they were unable to supple a simple spare screw. I looked at their demo unit and 2 screws where about fall out! I have also had 2 drive belts strip and found replacements on line. Much cheaper than replacing the whole cutter assembly but a very difficult and fiddly operation.
