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.

stroke and 4-stroke lawn mowers can use the same type of fuel – unleaded petrol with at least an 87 octane rating and no more than 10% ethanol (ideally 5%). This applies to both self-propelled and push lawn mowers. 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.To clear fuel out of the engine when you finish mowing, switch the fuel valve to the off position and start up the motor. Leave it running for a few minutes until it cuts out – when it stops, this means that all the fuel has been purged from the carburettor and fuel system. How to store lawn mower fuel and prevent it from going stale This is the 5 litre jerry can used to store petrol in the UK. You have a finite period of time that you can run the grass trimmer for before the battery runs out. Tougher tasks may make the battery drain faster, and recharging can take the best part of an hour which can be interruptive. As a result, they’re not the most appropriate for longer jobs.

The materials used in this petrol strimmer’s construction aren’t up to what you’d find on a Stihl strimmer, but they are still good quality and a fraction of the price. The frame is a rust-proof alloy and heavy-duty plastic; it looks and feels robust and hard-wearing. Remember, cc measures the capacity or displacement of the engine, and not its power output. It’s the amount of fuel and air that can be pushed through the engine cylinder(s).There is some weight to the Stihl, but it isn’t what I would consider heavy for this kind of product, and I take a little bit of weight as a good sign of solidness and quality. When in the harness, you hardly notice the weight anyway, and the tool always feels well-balanced and easy to manoeuvre. Petrol hedge trimmers are more powerful than electric or corded models enabling you to achieve a faster work rate. There are positive and negative aspects to both types of hedge trimmers. Which style is best for you will be dependent on the trimmer that best suits your requirements Electric Hedge Trimmer A lightweight design guarantees user comfort and allows a wide range of tasks to be done with one machine. In addition, a body harness is supplied for safe and comfortable operation. Pros:

Some trimmers have what are known as “wrap-around handles” that allow you to rotate and hold the trimmer at various angles, making it easier and more comfortable to use. Safety 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.Vibration levels are low on the Stihl, and I think this is due n large part to the high-quality materials used in its construction, coupled with some top-notch engineering. Everything on this product just lets you know that it is part of something better than the average, and I have to admit that it’s a nice feeling. Petrol hedge trimmer blades do the cutting and the bulk of the hard work, therefore, you must select a hedge trimmer with the trimmer blades best suited for the hedges you will be trimming.
