Best Petrol Lawn Mower Buying Guide
Engine Power and Displacement
Engine size directly affects cutting ability on thick grass and larger lawns. For most residential yards, a 140cc to 200cc engine provides ample torque. Larger displacement engines (200cc and above) handle dense vegetation and wet grass more effectively.
Consider the terrain: hilly properties benefit from engines with higher torque ratings. Many models use overhead valve (OHV) designs for improved fuel efficiency and lower emissions.
Check the fuel tank capacity as well; a larger tank means fewer refueling stops during long mowing sessions.
When comparing petrol mowers, look at the manufacturer’s recommended cutting area. Some engines are designed for smaller plots, while others can handle up to an acre. Our best performing lawn mower guide highlights models that excel in raw power.
Keep in mind that a more powerful engine often adds weight, so consider your ability to maneuver the mower if it is not self-propelled.
Cutting Width and Deck Material
Cutting width determines how many passes you need to finish your lawn. A 21-inch deck is common for mid-sized yards, while 14- to 17-inch decks suit smaller spaces.
Wider decks (22 inches and above) speed up mowing but may be harder to turn in tight corners. Deck material matters for durability: stamped steel is lightweight and affordable, while fabricated steel or aluminum decks resist rust and last longer.
Some premium models feature a reinforced deck for added rigidity on uneven ground.
For yards with lots of obstacles, a narrower deck provides better maneuverability. Our best small lawn mower article covers compact options. Also consider whether the mower offers mulching, bagging, or side discharge; many petrol models include all three for versatility.
Self-Propelled vs Push
Self-propelled mowers reduce physical effort by driving the wheels forward. They are ideal for sloped lawns or larger areas where pushing a heavy mower becomes tiring. Most self-propelled models offer variable speed control, allowing you to match your walking pace.
Push mowers are lighter and more affordable, but require more effort on hills. If you have a flat lawn under a quarter acre, a push mower is often sufficient.
For advice on choosing between the two, see our best push lawn mower roundup.
Consider the drive system: front-wheel drive (FWD) works well on flat terrain, while rear-wheel drive (RWD) provides better traction on slopes. All-wheel drive (AWD) is best for uneven ground. Our best AWD lawn mower guide details models that excel on challenging lawns.
Ease of Maintenance
Regular maintenance keeps a petrol mower running smoothly. Look for features that simplify tasks: tool-free air filter access, a large oil fill cap, and a removable cutting deck for cleaning.
Some mowers come with a washout port that lets you hose off grass clippings from the underside. Check the availability of replacement parts such as blades and belts. Our best quality lawn mower article includes models that require minimal upkeep.
Electric start models eliminate the hassle of pulling a cord, especially in cold weather. Many modern petrol mowers include a key start or push-button ignition. For storage, consider a folding handle that reduces space.
If you plan to store fuel over winter, use a stabilizer to prevent gumming. Our Garden & Patio section has more tips on outdoor equipment care.
Budget and Value
Petrol mowers range from around $65.00 to over $479.99. Entry-level models often have smaller engines and steel decks, while premium options include self-propulsion, larger cutting widths, and better build quality.
Determine your budget based on lawn size and how often you mow. For occasional use on a small lawn, a budget model may suffice.
For frequent mowing on a large or challenging yard, investing in a higher-end mower pays off in reliability and comfort. Our best inexpensive lawn mower guide highlights options that offer great value without breaking the bank.

Frequently Asked Questions
What size engine do I need for my lawn?
For lawns under half an acre, an engine between 140cc and 160cc is usually sufficient. For larger properties (half to one acre), consider 160cc to 200cc. Engines above 200cc are best for tough terrain or thick grass.
Always check the manufacturer’s recommended lot size for the model.
How often should I change the oil in a petrol mower?
Most manufacturers recommend changing the oil after the first 5 hours of use (break-in), then every 25 hours or once per mowing season. Use the oil type specified in the owner’s manual. Regular oil changes extend engine life and maintain performance.
Is a self-propelled mower worth the extra cost?
If you have a sloping lawn or mow more than a quarter acre, a self-propelled mower significantly reduces fatigue. It also helps you maintain a consistent pace for a cleaner cut. For small, flat yards, a push mower is more affordable and easier to store.
Can I mulch with a petrol mower?
Yes, most modern petrol mowers offer a mulching option that cuts grass clippings finely and returns them to the lawn as natural fertilizer. Check if the mower includes a mulching plug or a dedicated mulching blade.
Some models also allow you to switch between bagging and side discharge.
How do I store a petrol mower for winter?
Start by running the engine until the fuel tank is empty to prevent gumming, or add a fuel stabilizer. Change the oil, clean the deck, and remove the spark plug for inspection. Store the mower in a dry, covered area.

What is the difference between a push and self-propelled mower?
A push mower requires you to provide all the forward motion, making it a good workout. A self-propelled mower uses a drive system to move the wheels, so you only guide it.
Self-propelled models are heavier and more expensive but easier to use on large or sloped lawns.
