This Hyundai strimmer has the most powerful engine, with a 50.8cc engine that makes short work of any brush cutting and strimming you need to perform. This efficiency is aided by the 45cm cutting breadth. With a weight of 18kg and a capacity of 0.8L, it's a good thing this machine is on big wheels. This strimmer is not just for those searching for a powerful strimmer, but it is also an option for people who are unable to lift other strimmers due to the wheels. PROS It weighs 8.9 kg and has handlebar-style handles to provide a good grip on the strimmer – especially useful when working through tougher terrain; however, the harness could be of better quality to help more securely distribute the weight. When you don’t need something quite as heavy duty, the included grass trimmer attachment will come in super handy. Practicalities A tap-and-go feed head sees a gentle bonk upon the ground enough to feed some more line through should it get cut short by an obstacle. The unit splits in half for storage, too, which is incredibly handy. All in all, the combination of power and convenience here makes the Trimmac easy to recommend.

The motor must be primed by squeezing the bulb under the carburettor, which is standard procedure for all gasoline strimmers. The ParkerBrand 52cc brush cutter is fitted with a three bladed brush cutter blade which is ideal for getting through that dense foliage. Anything from scrub and brush to brambles and overgrown areas won’t stand a chance. For neatening up lawn edges, as well as cutting through tougher shrubbery like brambles, the Ryobi 2 in 1 Petrol Grass Brush Cutter is a solid choice: powerful yet lightweight.The AGILLO can spin at a maximum of 7,200 times per minute. Electronic speed control maintains the power under control, allowing for fine-tuning to each application. PROS The majority of 20 cc + petrol engines will be capable of clearing dense vegetation etc. But you may have to put it more work driving the machine forwards through the brush if it has less power.

Whether you’re struggling with overgrown grass, shrubbery, weeds or brambles, investing in a petrol grass trimmer is one of the best ways to keep your garden under control. However, if you’re using your strimmer professionally or will be working on lots of heavy-duty tasks, I recommend a strimmer with a 52 cc engine.Yes, you can buy a garden multi-tool or a 2-in-1 strimmer and brushcutter. Some strimmers come as part of kits that can include items such as rotovators, brushcutters, hedge trimmers and even small chainsaws for trimming branches. These multi-tools can save you money by only requiring you to own one engine to power several tools, but there is a major downside – if that engine stops working, all your tools are useless. What’s the difference between a strimmer and a brushcutter? The line head has a 43 cm cutting path so it doesn’t take long to cover larger areas either; if you have parts of the garden where the mower can’t go, this strimmer should be able to get in and help keep things looking tidy – especially useful around fountains, benches and playgrounds.
