How We Rated The Petrol Lawn Mowers
Over the years, we have tried and tested a wide range of petrol lawn mowers and as we have a relatively large garden, we continue to use petrol as opposed to electric or battery power. This is primarily due to the additional power and freedom to roam anywhere.
Therefore, along with our experience of using petrol powered lawn mowers, we also based our recommendations upon plenty of research and a number of factors. Some of the factors that we considered included the type, cutting width, cutting height options, grass collector, petrol engine performance, additional accessories, warranty and value for money.

Petrol Lawn Mower Buying Guide
Petrol lawn mowers have been the go-to choice for many people for years. They allow you to freely roam without the worry of finding a power supply or finishing the job before the battery runs out.
If you have a medium to large garden with banks or slopes, investing into a petrol powered mower is a great investment. The additional power allows you to achieve a far better cut with very little effort. They are also known for being far more durable than the alternative powered lawn mowers too.
To help you make an informed buying decision, we have produced the below guide regarding petrol lawn mowers.
Electric vs Petrol Powered
Choosing between an electric or petrol lawn mower is a difficult choice as they each have benefits and drawbacks. The benefits of using a petrol powered mower include:
- Free to roam without being tied to a power supply
- No risk of cutting through a power cable
- No need to constantly move the power cable out of the way
- More readily available power
- More durable
However, they do have drawbacks that include:
- Much heavier
- Usually more expensive
- Harder to push without being self propelled
- Requires petrol to run and servicing
- Much noisier
Another alternative that can also be considered is a cordless battery powered mower. These remove the hassle of a power cable but instead have the drawback of having to remember to charge the battery. There is nothing worse than getting halfway through cutting the lawn and then running out of battery.
For tackling medium to large gardens, the petrol lawn mower is by far the best option.
Push vs Self Propelled Petrol Lawn Mower
Cutting your lawn can become fairly tiresome for those with medium to large gardens. To help reduce fatigue, many manufacturers offer a self propelled lawn mower with some premium examples having multiple speeds to choose from.
Push mowers are the cheapest option and are ideal for flat gardens under half an acre. However, the ease of using a self propelled lawn mower is highly desirable as they push themselves with power usually being sent to the rear wheels.
For tackling medium to large gardens, they are perfectly fine but for multiple acres of grass, you would probably require a ride on lawn mower.
The Engine
Petrol powered engines that are used in lawnmowers have improved massively over the years. Improvements include a reduction in fuel consumption, lower levels of noise and less emissions.
Older petrol lawn mowers were mostly 2 stroke engines but due to emissions they have been phased out. The majority of petrol lawn mowers use 4 stroke engines, which have the benefit of not having to mix oil and improved fuel economy.
Cutting Width and Height
Due to the extra power that comes with a petrol lawn mower, you are able to cut grass easier using a wider pass. For large gardens in particular, you will want to be as efficient as possible. Therefore opting for the widest opening will help speedup the cutting the task of mowing your lawn. However, if you have a relatively small garden with lots of curves, it would be advised to go for a smaller width.
Grass Collection
Although not essential, most lawn mowers will come with a grass collection container. This is either constructed of a lightweight mesh material or a plastic container. Depending on the size of your garden, you will want to choose the appropriately sized grass collector.
If you prefer to not collect the cut grass, some lawn mowers have the functionality known as mulching. In short, the lawn mower cuts the grass even further into even smaller pieces, which is then outputted back onto the grass. This has the added benefit of keeping the grass green and healthy but also avoiding the task of emptying the grass collector.
Starting System
Some petrol engines have integrated an electric start button to get the the engine up and running more easily. However, not every lawn mower will have this feature and they may use a recoil start system, which may not be suitable for some people.
Maintenance Tips
One factor that some people worry about regarding petrol powered mowers is the maintenance that comes with them. However, it really isn’t too bad and it will only ever need servicing once every season depending upon its usage.
Below are serving tasks that you should carry out after every season:
- Change oil
- Replace fuel filter
- Replace spark plug
- Clean cooling system
Unlike a car engine, serving your lawn mower is far easier and can be completed within an hour. Before using the petrol lawn mower, you should always check the oil level beforehand. It will take less than 30 seconds to check and it avoids any expensive damage. Briggs & Sratton have an excellent guide that goes through each step in detail.
Conclusion
Petrol lawn mowers are highly desirable for many due to their powerful engines and durability. However, the main benefit is the fact that you are able to roam freely without having to worry about battery charge or a power supply.
All of the recommendations within this article cover a range of lawn mowers that are suitable for all budgets. Before purchasing, we strongly recommend that you ensure the lawn mower you choose meets your requirements.
