Buying Guide: How to Choose the Best Petrol Lawn Mower
Choosing the right petrol lawn mower can feel like a big decision. I have been through it myself, standing in the store or scrolling online, wondering which machine is the right one for my garden. It is not just about power; it is about finding the perfect partner for your weekend chores. Let me walk you through the main things I consider, so you can find one of the 10 best petrol lawn mowers to buy now with confidence.
First up, think about your lawn’s size and terrain. For a small, flat lawn, a basic push mower with a 140cc engine might be all you need. But if you have a larger area, maybe half an acre or more, you will want more power—look for something in the 160cc to 190cc range. If your garden has hills or uneven ground, a self-propelled model is a game-changer. It does the hard work of pushing for you, so you just guide it. This feature saves your back and makes the job much faster.
Next, let us talk about the mower deck. This is the housing that contains the blade, and its size determines how wide a path you cut. A wider deck means fewer passes to cover your lawn. Common sizes are 19, 20, or 21 inches. A 21-inch deck will get the job done quicker than a 19-inch one on a big lawn. Also, check what the deck is made from. Steel is durable but can rust, while polymer is rust-proof and lighter, which is a nice bonus.
Then there are the cutting features. The two big ones are mulching and bagging. A good mulching kit finely chops the grass clippings and returns them to the lawn as natural fertilizer. If you prefer a super-clean look, a rear bagger is essential for collecting clippings. Many of the best models offer a 3-in-1 system, letting you mulch, bag, or side-discharge clippings depending on your mood and the condition of the grass. Also, look for a mower with a single lever that lets you adjust the cutting height for all four wheels at once. It is a small detail that makes a huge difference in convenience.
Finally, do not forget about practicality. How easy is it to start? I always look for a mower with a primer bulb and a reliable starting system. Check the warranty, as a longer warranty period often reflects the manufacturer’s confidence in their product. And think about storage—does it fold down for compact storage? By weighing up your lawn’s specific needs against these features, you will be well on your way to making a great choice.
Frequently Asked Questions
What is the main advantage of a petrol mower over an electric one?
The biggest advantage is complete freedom from a power cord and the unlimited runtime compared to a battery. You are not limited by the length of an extension lead or the life of a battery pack. This makes petrol mowers the go-to choice for larger lawns, especially those over a third of an acre. They also tend to have more raw power, which helps them power through thicker, overgrown grass without slowing down.
How often does a petrol lawn mower need maintenance?
Regular maintenance is key to keeping your mower running smoothly for years. The most important task is an oil change; I do this once a season or after every 25 hours of use. You will also need to replace the air filter and spark plug at least once a year. Always remember to use fresh, ethanol-free fuel if possible, or a fuel stabilizer if you are storing the mower for more than a month, as old petrol can gum up the carburetor.
Are petrol mowers difficult to start?
Modern petrol mowers are much easier to start than older models. Most come with a primer bulb that you press a few times to send fuel to the carburetor, and a recoil start pull cord. The technique is simple: set the throttle to choke, press the primer bulb 3 times, pull the cord firmly. Once it sputters, move the throttle to run and pull again. Following these steps usually gets mine going on the first or second pull when the engine is cold.
What safety gear should I wear when using a petrol mower?
Safety should always come first. I never operate my mower without sturdy closed-toe shoes (preferably steel-toe cap boots) and protective safety glasses or goggles. The mower can throw out stones or debris at high speed. It is also a very good idea to wear hearing protection, as petrol mowers are quite loud and prolonged exposure can damage your hearing. Long, heavy-duty trousers are also recommended.
Is it worth paying more for a self-propelled model?
In my opinion, if you have any kind of slope or a large lawn, it is absolutely worth the extra investment. A self-propelled mower has a drive system that pushes the mower forward for you. You just guide it. This makes mowing hilly or uneven ground much less physically demanding and drastically cuts down on fatigue. It turns a strenuous chore into a simple walk around the garden.
Can I use a petrol mower on wet grass?
It is best to avoid it if you can. Mowing wet grass is not ideal for any mower, but it is particularly troublesome for petrol models. The wet clippings clump together, clogging the deck and the discharge chute, which can stall the engine. It also leads to an uneven cut and can mat down the lawn, which is unhealthy for the grass. I always wait for the grass to dry before I get my machine out for the best results and to keep it in top condition.
