What is a Petrol Lawnmower?

A petrol lawnmower use and engine to power the blades and, in some models the wheels of the mower, giving the user more power, control and ease of use.

A petrol lawnmower serves the same purpose that an electrical one does, except it also has a whole heap of features that are simply not available in their electrical counterparts.

Firstly, petrol lawnmowers possess a lot more power than any other lawnmowers due to their petrol-fuelled engine.

This makes short work of any terrain and grass thickness. Many petrol mowers feature an engine also powers the movement of the mower, meaning you can change the speed of the mower and you just need to keep it on track.

People of all strengths and sizes can use these types of petrol mowers effectively, with no need to push them hard across the garden.

How Does a Petrol Lawnmower Work?

The first electrical lawnmower was invented in 1926 which allowed people to cast aside their hand-powered blade reels and a new dawn of lawn maintenance began.

What was then a revolution in the industry has been far surpassed by the petrol mowers available today.

A petrol mower has a blade held within the ‘deck’ of the mower, which is powered by the petrol-fuelled engine, spinning at high speed and cutting the grass beneath it.

As it is a combustion engine, you will also need to ensure it is kept topped up with engine oil, but you’ll be fully informed of this when you purchase from a reputable dealer.

Despite being fuelled by petrol, the mowers run on a small amount depending on the size of the engine on the mower.

The average walk-behind mower holds around a litre of petrol, which is only about £1.10, and that will keep it running for a great deal of time before needing to refuel.

Typically, the mower will need petrol with an octane level of 87 or higher.

Types of Petrol Lawnmower

Here, we break down the three different types of petrol lawnmower, so you can make a decision on which type would be most beneficial to you and your home.


These types of lawnmowers are the most popular option amongst UK households, and they’re generally the cheapest options on the market.

This type of lawnmower uses a horizontal blade spun at high speeds to cut the grass below it. Rotary mowers are certainly an effective option, but there are mowers that offer a finer cut for those that value it.

If you’re looking for a striped garden look, you’ll need a rotary mower that also has a roller attachment built into it.

These mowers are perfect for cutting through long grass that has been unkempt for a while as the power-driven from the motor is far superior to that of an electric mower.

Rotary mowers range in price from £150-£1,500, with different brands, engine power and styles acting as pricing factors. However, even the cheapest option will perform far better than an electric rival.


Cylinder petrol lawnmowers are popular amongst garden enthusiasts and landscaping professionals.

They provide the best finish on grass due to their range, flexibility and precision, scissor-like cutting ability.

Due to this precision, they are more expensive than other types, but if you value the best cut and finish, this should be your target mower.

However, these mowers are best used on shorter grass that needs perfecting and won’t perform well on thick or long grass.

The pricing for cylinder mowers starts at around £800 and rises up to £4,500 for mowers designed for surfaces like cricket or bowls pitches.


These types of mowers look like they’ve come straight from a Sci-Fi movie. Hover mowers work in the same way as a rotary mower, with horizontal blades working at high speeds powered by the petrol motor.

However, instead of featuring wheels to move the mower around the surface, it instead has a powerful fan and ‘skirt’ that produces a pocket of air that lifts the mower off the ground.

This allows you to mow uneven surfaces accurately, allows you to move in any direction you wish and means that it is very easy to use for those that don’t have the strength to push an electrical mower.

These types of mowers aren’t as effective in the long grass as a simple rotary-style but do perform better than a cylinder in the same regard.

Hover mowers are around £500 across the board, which is a fantastic price considering the versatility they offer.
