Our Gtech HT20 Long Reach Hedge Review

18V Li-Ion CordLess Unit

The Gtech cordless hedge trimmer HT20 is a tool many of us need if we have tall hedges such as privet, leylandii, laurels or similar and want to avoid the cords and petrol motors associated with the alternative electric or heavy petrol models. The advantage with this unit is that it comes with all the features you might find in a petrol or corded electric based model. The unit obviously is cordless and thus will need reliable batteries of which Gtech seem to have put a-lot of thought into. The battery it comes with is a 18V Lithium-ion battery which is very compact and, they are able to store adequate charge to be used for longer periods of time, we could not verify what Amh the battery is but its fairly large as we know it has a longer running time than most other hedge trimmers we have reviewed in the past, which is usually around 30 minutes which is much less than what the Gtech models is capable of.

These batteries take up to 4 hours to charge so fairly fast but some models are now capable of charging batteries in 1 hour. However it is still short time compared to some models available in the market which take 6 hours. Once the unit is fully charged, there is an indicator that informs you that the process is completed. Once charged, the hedge trimmer will work for around 45 minutes giving plenty of time for most medium sized hedges.

Adjustable head

One of the more notable features is the adjustable head which we love and think is very useful. With many hedge cutters, angled cuts tend to be challenging. Instead of the user twisting their hands to get a good cutting angle, the head does this instead. Once you set the cutting head at the right angle, all you have to do is sweep the blade over the required area and voila!. simply a great feature which means no more getting to ladders to trim the top of the hedge.

Lightweight unit

As stated before, this is a lightweight unit. Weighing in at only 2.25kgs, it is rather easy to use the unit. A problem might arise if you choose to use the extendable pole. Due to the structure, some people may find the unit top heavy and thus cause some unwanted strain. This will probably not be a problem for most people but some users are sure to notice the extra weight on there arms. Personally we think its no more top heavy them most other models.

The hedge trimmer can be transformed into a branch cutter. The branch cutter and extendible pole are purchased independently, therefore, remember to add the numbers before purchasing. This versatile feature will save you time and the expense of getting individual trimming tools for your garden. The branch cutter is excellent for trimming those thicker branches and is much saver then using a chainsaw type head or bow saw.

Durable construction

Blades contributes a large factor as to the optimal performance of any hedge trimmer. Materials such as steel are popular for durability. The dual blade featured in this model is made of high-quality steel which in turn won’t bend or get blunt easily. The 31cm blade with 1.5cm tooth spacing can be replaced or sharpened with ease if needed but as long as you keep your hedge well trimmed regularly to avoid excessive stress on the blade because of thicker branches, this should not be a problem to most. 

Final Conclusion

The Gtech cordless hedge trimmer HT20 is not one of those frustrating models that take up your time with lack the power and is super heavy. This is the total opposite, plenty of power, lightweight and easy to use. Once the battery is fully charged, all you have to do is press a button and you are good to go. A waiting time of 4 hours is manageable for the price and the running time is more than sufficient at 40 minutes. If you have a small area to cover then this hedge trimmer will work perfectly but if you have a larger hedge it would be worth considering a spare battery.

Admittedly, if you want to buy the whole set plus accessories, it will cost you more. But, it is a worthy investment since you won’t have to buy other hedge trimming accessories and they do come in handy for them off thicker branches and extra reach if needed. This lightweight unit is effective and provides enough torque to deal with the new foliage in your garden.

We hope that the review has sufficiently indicated what to expect when you decide to purchase this model. What we would like to point out is that it will not cut a hedge that has not been cut for years, this model is designed to keep hedges trimmed regularly and will not cut though really thick branches on unmaintained hedges as the branches will be too thick. Our advice if you have a hedge which is really overgrown is to get a professional to trim the hedge and then you can trim the hedge every 3 or 4 weeks.

Do you think it makes a good addition to your landscaping tools? If so? What are you waiting for? Grab yourself the Gtech cordless hedge trimmer HT20 and get those hedges up to par.
