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. Best Place for Engineering and Technology, Air Standard Assumptions". Archived from the original on 21 April 2011. 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). Specification: Warranty: yes (1 year) , 2 or 4 stroke: 2 stroke , Engine power: 2.2 kW , Weight: 10.7 kg The Makita EH7500 is powered by a 2-stroke, 22cc motor, which, although slightly smaller the most motors used for petrol hedge trimmers, runs at twice the speed of similar engines at 4390 rpm.

To prevent your lawn mower fuel from becoming stale, you should store the petrol in an airtight jerry can, out of direct sunlight. Other handy features that Mculloch has seen to adding are that you can access the air filter without the need of tools, and made the fuel tank transparent so you know when it’s getting close to the time to fill up. Thankfully, with it’s excellent fuel consumption, those refills are few and far between. Some of the best petrol strimmers for really tough jobs will have a 52 cc engine. Other machines have closer to a 20 cc engine – but which should you be looking for? Most modern production engines use hydraulic lifters to automatically compensate for valve train component wear. Dirty engine oil may cause lifter failure.Along with the harness, a tool kit and fuel-mixing bottle come included. Whilst you may get more from using your own tools for maintenance, the bottle is useful for easily combining the petrol and oil needed before starting. McCulloch has taken into consideration the fact that petrol strimmers shake a fair bit when operating at high revs, and have installed an anti-vibration system that sits just under the engine, a nice touch and to be expected of a higher quality piece of kit. This is one of the better anti-vibration features that I’ve seen, and when compared to most of the trimmers I’ve had in the past, there was a significant reduction in shaking. Petrol-powered strimmers are generally quite heavy – often over 10 kg – which can be quite difficult to support whilst doing longer jobs, even if a harness is included.

The Parker Brand 52cc Multi Function 5 in-1 Garden Tool is a multi-tool ideal for heavy-duty garden maintenance. Powered by a 2-stroke 52cc petrol engine that is easy to start, this tool will make light work of even the toughest grass, weeds, and branches. 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.Assembly is straight forward enough, but again, the instructions could have been a bit better. I think it’s very straightforward so they half expect you to know what to do. I’d suggest looking for videos and such online to help if you’re not sure, there are plenty of instructions online, it is honestly pretty easy to sort out. 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. 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.

There is a bump-feed head that feeds out line, but no brush-cutter blade head; although, again, this makes sense given the type of work it is suited to. Petrol strimmers aren’t generally used for small jobs – they’re tough machines that are well suited to clearing large areas and tough undergrowth. The engine capacity and horsepower of your petrol leaf blower, as well as the design of the motor, will help to determine its air speed.

Considering that petrol strimmers can be very powerful machines, it’s worth doing a bit of research before getting one, to make sure it’s the best petrol strimmer for you, your garden, and your lifestyle. If the hedges you intend to trim are 6ft or less high, then a standard petrol hedge trimmer will be more than adequate. Long-reach Petrol Hedge Trimmer Nikolaus August Otto was a traveling salesman for a grocery concern. In his travels, he encountered the internal combustion engine built in Paris by Belgian expatriate Jean Joseph Etienne Lenoir. In 1860, Lenoir successfully created a double-acting engine that ran on illuminating gas at 4% efficiency. The 18litre Lenoir Engine produced only 2horsepower. The Lenoir engine ran on illuminating gas made from coal, which had been developed in Paris by Philip Lebon. [2]
