Should I Buy a Petrol Mower Or a Battery Mower?

If you are looking to treat your garden to a new mower, your most likely stuck between the decision of buying a petrol mower or a battery mower.

A while back this would have been an easy decision, as electric mowers had cords, but now battery-powered mowers offer the same freedom that petrol mowers had the advantage of, making the choice harder.

Each type of mower is no better than the other, as they both come with there pros and cons, meaning the choice of your mower will come down to personal preference and your type of lawn, as well as its size. 

We have put together a guide below which will explain the differences, as well as the advantages and disadvantages of each type of mower below, to help you make a decision about which type of mower is right for you.

What Is The Difference Between Battery & Petrol Mowers?

Before we can dig into comparing the pros and cons of petrol and battery mowers, we first need to understand how both types of lawnmowers work.

Petrol mowers use an engine to operate with and have a spark plug, almost like a car. They typically need to be pulled to start and need ongoing maintenance like oil changes for them to work efficiently.

Battery mowers, on the other hand, do not need this maintenance and get their power through a charged battery rather than an engine. These mowers just tend to have a push start button.

Battery VS Petrol Mowers - Pros & Cons

Now we know the main difference between each kind of mower, we can get on to comparing the advantages and disadvantages to how they run and perform on grass, so as you can decide which mower is right for you and your garden.

Battery Mowers

First, let's start with battery mowers. Battery mowers have the advantages of being environmentally friendly and low maintenance in comparison to petrol mowers as they emit no fumes and don't have an engine that needs to be taken care of.

These mowers additionally tend to be less noisy and very easy to use due to there push-button start and lightweight, which makes them easy to store and move around.

Disadvantages of these mowers have to be there lack of power, which means they aren't as good as petrol mowers for cutting tall grass and large lawn sizes. The battery also needs recharging which can interrupt your workflow, and there is always a risk of electric shock.


  • Environmentally friendly.
  • Lightweight.
  • Easy start.
  • Quiet.
  • Low maintenance.


  • Risk of electric shock.
  • Not as much power for thicker and taller grass.
  • The battery needs to be recharged.

Petrol Mowers

Petrol mowers are a great traditional option for cutting your lawn as they can handle thick and tall grass, as well as larger sized gardens better than battery-powered mowers.

In terms of price, these mowers also have a cheaper price than battery models and a wider range to choose from on the market.

Drawbacks of petrol mowers have to be there constant matienance which is needed on the engine, such as changing the spark plugs and oil, they are also more likely to run into engine issues.

Due to the fact these mowers run on fuel, this makes them less friendly to the environment, they are harder to start and store too due to the pull start mechanism and heavyweight these mowers have.


  • Cheaper price with a wider range of choice.
  • Best for tackling large gardens and tall grass.
  • Not battery recharge needed and no risk of electric shock.

If you have a larger garden, you are experienced with mowers and you don't mind the maintenance, you might be more suited to a petrol mower if you are okay with the environmental effects.

On the other hand, if you have a small backyard garden that just needs some maintaining now and then and you have a higher budget, a battery mower is the suitable choice.
