Petrol Strimmer Buying Guide

Buying a petrol-powered garden strimmer is a great way to ensure you’re able to tackle any gardening job, whether clearing overgrown grass, brambles, shrubbery or weeds. Few garden tools are more useful or more versatile, and petrol strimmers run forever with very little maintenance. If we could only own two garden tools, we’d choose a petrol strimmer and the best petrol lawn mower you can find.

Like all power tools, the petrol strimmer needs to be handled with care so there are a few things you should know before deciding to take the plunge and purchase your own. That’s exactly where this guide comes in, as we know the ins and outs of these grass trimmers and can lead you to the best one for your tool kit.

Cutting Power

Garden strimmers are powered by petrol engines, mains power or battery. Petrol strimmers are actually the most common type and are also usually the cheapest to purchase with cordless battery strimmers being some of the most expensive. The main difference is that you’ll need to buy fuel for the fuel tank which will add to running costs.

Some petrol strimmers can be noisy and heavier than their electric counterparts, but the upsides are increased power and performance. The larger your garden, the more you’ll benefit from this type of strimmer. Petrol trimmers come with a 2 stroke engine or 4 stroke engine. We suggest going for the 4 stroke petrol engine for ease of use.

Cutting Width

The cutting area or width of petrol strimmers can range from 25cm up to 50cm. This measurement refers to the size of the cutting head which will vary by machine. Many strimmers feature an adjustable cutting width which allows you to fine tune your strimmer to the requirements of the job.

The larger the cutting area, the greater the area of grass or foliage you’ll be able to cut at one time. Perfect for those larger jobs which involve clearing large areas in one go.

If you have a smaller garden with lots of plants or other obstacles, using the smallest cutting width will be required to prevent accidental damage to both your strimmer and your flowers.

Ease of Starting

Modern strimmers are much better than their older versions. A common issue used to be the difficulty and time taken to get the strimmer started. Newer versions are designed to be easier to start with less priming (using a choke) required to bring the motor to life.

Look for models with a push start button rather than a pull cord as they are much more user friendly.

Blade Durability

Blade durability is an important factor, even if you don’t think you’ll be tackling any heavy duty gardening jobs. A high-quality blade will last longer and is far safer under stress, lowering the potential for injury and damage.

Always look for the highest quality brush cutting blade you can find. Blades with 3-7 teeth are perfect for clearing brush and thin branches. 30 tooth blades are better suited to thick, dense foliage including brambles.

If your strimmer uses a spooled strimmer line, make sure its durable enough for the jobs you plan on doing.

Handle & Ergonomic Comfort

Your strimmer should be comfortable to use, both for ease of use as well as your safety. All handles should be easy to grip and should allow you the control and range of motion required.

The better grass strimmers feature a handlebar style setup which allows you to evenly distribute weight across both arms. Each model should come with a shoulder harness too which assists with increased control when using your strimmer.


Petrol strimmers typically weigh in at around 10-12kg when full of fuel. This isn’t a lot of weight but can take a while to get use to if you have never used a strimmer before.

Newer models are designed to be lightweight and easier to control but you should always use the supplied harness. This straps the strimmer to your torso, taking much of the weight off your arms so you can control it better.

Safety is the number one priority so never persevere if you’re finding using your petrol grass trimmer to be too difficult.

Final Verdict

The best petrol strimmer is the one that is best suited to your requirements and offers the best value for money. Our top pick, the Ryobi 2-1 petrol grass trimmer is a safe bet and is the one we’d go for, but if one of the other models better suits your needs, you’ll be served by a high-quality tool that will last for years.
