Prepare the fuel and oil. If your petrol grass trimmer has a two-stroke engine, you will need to mix the unleaded petrol and oil together before putting it into the fuel tank. With a four-stroke engine the oil and petrol are not mixed and go into separate tanks. The manufacturer’s instructions will show what type of oil should be used, and what ratio it should be mixed at. If a heavy-duty strimmer with a powerful engine is what you need then this garden strimmer by Hyundai will not disappoint. A double shoulder harness and ergonomic handle will give you good control of the 52cc, two-stroke engine.

This Einhell strimmer performed well on the grass at the edge of my lawn and on weeds (as seen in my demonstration video). Last but certainly not least is a great multi-tool option from Mountfield. The lawn trimmer is a simple tap and go nylon head to help you work efficiently. The brushcutter attachment is a 3 tooth metal blade, perfect for weeds and it even has a 40cm hedge trimmer attachment. a chisel blade (with 3 to 7 teeth) works for brambles, undergrowth or new growth measuring less than 3 cm in diameter; It’s also a brilliant option as an entry level petrol tool since it’s so easy to use and it’s highly unlikely that you’ll have problems getting it started thanks to the advanced technology within the workings of the engine system.If you need a lighter machine, there are options available such as the 3.9 kg McCulloch Trimmac Trimmer. Of course, the weight always increases a little after fuel has gone in as well. The downside of a lighter strimmer is that they can vibrate a lot, and they won’t be able to do the same tasks as more powerful and heavy models. That said, they are a good compromise if you want the power of petrol but are worried about manageability. The two-stroke engine starts relatively easily and requires a combination of petrol and oil, and you should consider using ear protection as well – it’s quite a noisy machine.

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. It’s not the most durable design and is prone to parts needing to be replaced after heavy use. As with most power tools, you get what you pay for. This one won’t last forever but it does a good job and is a powerful machine given the small price tag. The power cord. Mains-power strimmers keep you tethered whilst working in the garden. You will likely have to use an extension cable, and need to be aware of where the cable is at all times so as not to cut through it accidentally. If you’ve never used a petrol tool before then you’re likely umming and arhhing purely because of how notoriously difficult they can be to start. But that won’t be a problem with this Einhell since it has a starter flap on the carburettor which ensures the machine starts first time. Moreover, there’s a controlled flow of fuel so once it’s up and running, it’ll always be stable. The auto choke I mentioned earlier is also imperative in getting the machine fired up without any issues.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. In short, your choice of brushcutter depends on the size of your garden as well as the density of the vegetation you're hoping to clear. One of the things I love about this Einhell GC-BC 52 I AS petrol brushcutter is that it boasts a split shaft. This simply means that the shaft comes into two which makes storing and transporting the tool a whole lot easier. Despite having a 25 cc engine, at only 3.9kg it’s the best lightweight petrol strimmer on our list. For those who are worried about managing heavier weights, but still want something with plenty of power, it’s a great option.
