The fuel that powers these machines needs to be mixed correctly for optimal performance and maintenance is essential to keep them running smoothly.

Electric hedge trimmers have become increasingly popular in recent years due to their quiet operation and convenience, however petrol models still remain a favourite amongst professional gardeners due to their superior power output over electric models.

With the right care and maintenance,  a high-quality petrol hedge trimmer should endure for many years, delivering dependable performance in any garden situation. Moving forward, it’s important to choose the right model for your specific needs as there are various sizes, features and prices available on the market today.

Choosing the Right Trimmer

To swiftly and efficiently trim those hedges, you’ll need to choose the trimmer that best suits your requirements. Look for a petrol hedge trimmer with features like handles, cutting blades, performance, range, height of the hedge trimmer blade, stroke engine or petrol engine with an antivibration system that will give you added protection and control while trimming. The type of hedge you have will also influence your decision—consider a twostroke engine if it’s small or one with a higher engine capacity if it’s large. Additionally make sure to use twostroke engine oil and check the fuel consumption along with regular maintenance.

Make sure to look at features such as gear systems and grips when selecting your petrol model, as well as filters and plugs for safety reasons. It’s important to consider other factors like weight too; some lightweight designs come with air compressors which can be useful especially when using longreach hedge trimmers on tall hedges. Professional users may want to opt for a professional hedge trimmer that has dual action blades for extended cutter life and an auto return stop switch for improved convenience.

Before making your final decision think about things like whether you should use unleaded petrol or mix technology in two-stroke engines, what size tank is needed based on how much fuel you’ll use regularly when trimming mature hedges without having to refuel often, whether you want additional safety equipment such as face guards and ear defenders as well as understanding the starting procedure of each particular model before purchasing. With all these considerations in mind you’re ready to move onto operating your chosen petrol hedge trimmer!


Now that you’ve chosen the perfect trimmer, it’s time to get those hedges in shape – rev up your engine and let the blades whir! Petrol hedge trimmers are a great choice for getting your garden looking its best. Operating them is as simple as following a few steps.

First, ensure that all safety precautions have been taken – check the spark plugs, make sure there’s no debris around the fuel tank, and get familiar with the rear handle and power source. It also helps to check if there’s any warranty on your petrol hedge trimmer before using it.

The next step is to fill up the fuel tank with petrol or diesel depending on the model of trimmer. Once that has been done, you should be able to start it up by pulling on the cord. If it’s a cordless model, just switch it on like any other power tool. For added comfort during use, make sure yours has an effective antivibration system and runs for several hours without needing refueling.

Petrol vs Electric

When it comes to hedge trimming, deciding between a petrol or electric model can be a difficult choice; each has its own unique advantages and disadvantages. In terms of equipment, while an electric hedge trimmer requires only the trimmer itself, petrol models require additional protective equipment such as safety glasses and gloves.

Additionally, petrol engines have a longer service life than electric ones: they are designed to last for extended periods without breaks in operations unlike their electric counterparts which need regular maintenance. Furthermore, most petrol hedge trimmers use pickup bodies and pieces of paper as fuel sources- something that qualified electricians cannot do.

Petrol hedge trimmers also provide more power than their electric equivalents. This increased power is essential when tackling larger hedges or thicker branches that require a heavier-duty motor to complete the job efficiently and effectively. Moreover, petrol engines produce fewer emissions than electric motors and typically require less upkeep – meaning you won’t have to worry about finding replacement parts or refuelling your machine too often.

The only real downside with using a petrol engine is the cost associated with buying one; they tend to be more expensive than electric models due to their higher performance capabilities. However, this cost can easily be offset by the fact that they are much more powerful and reliable over time compared to an electric model.

Advantages of Petrol

You can’t beat the power of a petrol hedge trimmer, it’s like a roaring lion cutting through even the toughest branches with ease. Petrol has several advantages over electric versions, making it an ideal choice for those tackling large and difficult trimming jobs.

Faster Cutting SpeedHeavyweight & Bulky Design
Longer Run TimeLoud Noise Level
More Power & TorqueFumes & Emissions
No Cords or BatteriesHigher Operating Cost

The power and speed of a petrol trimmer is significantly greater than its electric counterpart – you don’t have to worry about running out of charge mid-cut as you would with an electric unit, and the lack of cords mean you’re not limited in terms of how far away from an outlet you can work. What’s more, petrol hedge trimmers are highly durable machines that will last for years given proper maintenance.

Although they require more effort to operate due to their heavier design, often giving your arms a good workout in the process! Not to mention they are much louder than electric models so ear protection should be worn when using them. Lastly, while fuel costs may be higher compared to electricity bills, petrol trimmers offer better value for money in the long run due to their longevity and reliability – no need for costly replacements down the line!

Petrol hedge trimmers provide superior performance and are well suited for tough trimming tasks around your garden – perfect for keeping hedges neat and tidy all year round. They offer plenty of power and torque along with longer run times than their electric counterparts plus no cords means unrestricted movement while working.

With these benefits come some drawbacks such as higher operating costs due to fuel consumption as well as noise levels being far higher than with battery powered units. Nevertheless, if you’re looking for a dependable tool that can handle tough tasks then a petrol model could be just what you need! To pick up on this topic further we’ll now move onto discussing blade types…

Blade Types

Choosing the right blade for your petrol trimmer is key to getting the job done quickly and efficiently, so be sure to consider all your options before making a decision. One of the most popular types of blades used on petrol hedge trimmers is a double-sided blade with two sets of teeth on each side. This type of blade allows you to trim both long and short sections of hedges without having to switch out blades.

Another option is an angled head blade, which is designed for cutting thicker branches or those at awkward angles. It can also be used for creating precise edges around flowerbeds or borders. Finally, some models come with an edging tool that reduces vibration and makes precision cuts along edges and corners easier than ever before.

Another option when it comes to blades are laser-cut steel blades which boast greater durability and can cut through thicker branches more easily than other types of blades. They’re also equipped with anti-vibration technology, meaning they’re less likely to cause fatigue during extended periods of use.

The downside is that they tend to require more regular maintenance in order to keep them sharpened and in tip-top condition, however this shouldn’t deter you from considering them as an option if you have hardy hedges that need tending too regularly.

No matter what type of blade you choose, always ensure it’s made from high quality materials as this will help keep it sharp for longer periods – something that will save you time and money in the long run!

Additionally, make sure any safety guards are firmly attached before using the trimmer as these provide extra protection against flying debris while working with the tool – something that should never be overlooked no matter how experienced you may be at handling such machinery.

Wearing protective gear such as goggles or gloves whenever operating a petrol hedge trimmer isn’t just wise but highly recommended by experts too!

Safety Wear

Protecting yourself while operating a hedge trimmer is essential, so make sure you’re equipped with the right safety gear every time. This should include protective eyewear, gloves and sturdy footwear. It’s also important to wear long trousers and a long-sleeved shirt to protect your skin from flying debris. If you have long hair, tie it back securely so it doesn’t get caught in the blades of the trimmer.

When using a petrol hedge trimmer, always ensure that you are working in an open area away from any flammable materials or liquids. Make sure that there aren’t any children or pets nearby who could be injured by flying debris or fumes from the engine. You should also check that your lorry is parked at least 10 metres away from where you are working as exhaust fumes can be dangerous if inhaled for too long.

Before starting up your hedge trimmer, read through the manufacturer’s instructions carefully and familiarise yourself with all of its controls and features. Check that all nuts and bolts are secure before use and never attempt to operate a damaged machine – this could cause serious injury or even death!
