The STIHL HS 45 thermal hedge trimmer is ideal for trimming hedges, bushes or trees. It is powerful, easy to start and features anti-vibration systems for maximum comfort during work. The machine won’t stall while cutting, and it has a long-life air filter that reduces the frequency of engine maintenance. The diamond-ground blades and steel outer shell are wear-resistant, ensuring that the cutting edge remains in optimum condition throughout the life of the machine and extending the overall life of the unit. The protective sheath protects the cutter bar during storage and transport, preventing damage from scratches. This hedge trimmer is a more economical option than a normal electric hedge trimmer, as it uses fuel instead of electricity.

Use and maintenance

Like all STIHL hedge trimmers, the HS 45 has an optimised blade geometry that works with a drive specially adapted for maintenance and pruning work. This guarantees optimum cutting performance, especially in heavy-duty situations. But the HS 45 goes even further with a double-sided blade that is sharpened on one side to give you even more precision when you need it.

The Stihl HS 45 thermal hedge trimmer is perfect for small and medium-sized areas. The double comb cutting bar allows multidirectional cutting. This means you can easily cut in all directions on all types of job sites.

With the HS 45‘s long life air filter system, you don’t have to be a master gardener to ensure your engine is protected from dirt and debris. The filter keeps your machine running, so you don’t have to worry about changing your cleaning routine for a long time.

If you’re interested in Stihl’s thermal hedge trimmers, we’ve put together a comprehensive guide to help you.

Our opinion:
The Stihl HS 45 is an excellent all-round hedge trimmer for the homeowner or gardener. It can’t compete with other brands in terms of power and durability, but thanks to its unique double comb cutting bar, it offers greater precision when working.

Ergonomics and safety

You know how sometimes you just don’t feel like trimming your hedges? Maybe it’s before coffee, or maybe your fingers are cold, or maybe you’re just sitting on your patio drinking lemonade and looking at those hedges and thinking “I could sit here forever and never feel like doing this stupid chore”. So they’ve made their Stihl HS 45 thermal hedge trimmer easier to use – and more comfortable – than ever.

But how? It’s not just the ergonomic handles and the weight (just 4.7 kg). It’s also the anti-vibration system. They’ve placed four short springs between the engine and the support frame, and because they’re large-diameter springs, they filter out any unpleasant vibrations generated by the engine and cutterbar. The level of vibration is very low – very little jarring or bouncing – and that means less fatigue for you, which means you can work longer without having to stop for a break. The hanging eye makes it easy to store the machine when you’re done.

Our opinion:
The Stihl HS 45 has a cutting capacity of 45 to 60 cm, plenty of power and good autonomy. It’s a pleasure to hold – the design is first class. The anti-vibration system makes all the difference to the user. A small complaint: the hedge trimmer is still relatively heavy and bulky.


The STIHL HS 45 thermal hedge trimmer has a number of features that make it an excellent choice for thermal hedge trimming. Its priming pump allows you to quickly fill the carburettor with fuel before starting the engine by simply pressing on it with your thumb. This reduces the number of starting cycles after long periods of non-use, dry running or first use, and makes starting much easier and quicker.

Our opinion:
The STIHL HS 45 is a popular hedge trimmer with homeowners looking for high quality in a thermal hedge trimmer. Its many features make it easy to use, making it an excellent choice for homeowners who need to trim hedges for long periods of time.


The Stihl HS 45 is a thermal hedge trimmer that runs on a mixture of 2-stroke engine oil and petrol, giving it the power to cut difficult bushes. The engine produces 750 watts, which means it cuts more efficiently than electric hedge trimmers. The 27.2 cc engine is powerful enough to cut wood up to several centimetres thick.

Our opinion:
The best hedge trimmer for your needs depends very much on the size of your shrubs and the space you have to work in. If you have a lot of space but only a few shrubs, an electric hedge trimmer will be ideal. On the other hand, if you have a very large area to cover and lots of shrubs to look after, you might consider buying a motorised hedge trimmer. At around 329$, the Stihl HS 45 is one of the best motorised hedge trimmers on our list.
