Your Guide to Picking the Best Gas Lawnmower
Choosing a new gas lawnmower can feel like a big job. These machines make yard work faster. We break down what you need to know to find the right one for your lawn.
Key Features to Look For
Good features make mowing easier. Look closely at these important parts before you buy.
Engine Power and Size
Engines are measured in cubic centimeters (cc). For small, flat yards (under a quarter acre), a 140cc to 160cc engine works well. Bigger yards or yards with steep hills need more power, usually 170cc or higher. A strong engine cuts thick or wet grass without stalling.
Cutting Deck Width
The deck is the metal part that covers the blade. A wider deck means you cut more grass with each pass. Small yards benefit from 18-inch to 20-inch decks. Large lawns need 21 inches or wider to save time.
Drive System (Self-Propelled vs. Push)
- Push Mowers: You supply all the power. These are lighter and cheaper. They work best on small, flat lawns.
- Self-Propelled Mowers: The engine moves the wheels for you. This saves energy, especially on hills or large areas. Look for variable speed controls so you can match the mower’s speed to your walking pace.
Bagging, Mulching, and Side Discharge
Decide what you want to do with the grass clippings:
- Bagging: Clippings go into a bag you empty later. Good for neatness.
- Mulching: The mower chops the grass very fine and drops it back onto the lawn as natural fertilizer.
- Side Discharge: Clippings shoot out the side. This is quick but leaves clumps of grass.
Important Materials That Matter
The materials used affect how long your mower lasts and how much it weighs.
Deck Material
Most decks are made of steel or aluminum. Steel decks are strong and common. Aluminum decks resist rust better, which is important if you live somewhere rainy. Plastic decks exist but are usually found on smaller, less powerful models.
Wheel Quality
Plastic wheels wear out fast. Look for mowers with durable, large rear wheels, especially if you have uneven ground. Good wheels make steering much easier.
Factors That Improve or Reduce Quality
Small details often separate a good mower from a great one.
Ease of Starting
Modern mowers should start easily. Look for features like “ReadyStart” or “Easy Start” systems. These systems reduce the effort needed to pull the starter cord. A hard-to-start engine causes frustration every time you mow.
Adjustability and Handling
You need to adjust the cutting height easily. Look for single-lever height adjustments instead of moving each wheel individually. A good handle height prevents back strain.
Maintenance Access
Cleaning the underside of the deck is necessary. Some mowers let you tilt the machine forward easily without spilling oil or gas everywhere. This feature improves long-term care.
User Experience and Use Cases
Think about your actual yard when you shop.
Small City Yards (Under 1/4 Acre)
A basic push mower with a 20-inch deck is usually enough. Focus on lightweight design and good mulching capabilities.
Medium Suburban Yards (1/4 to 1/2 Acre)
A self-propelled mower saves a lot of energy here. Look for a mid-range engine (around 160cc) and a 21-inch deck.
Large Yards or Hilly Terrain (Over 1/2 Acre)
You need power and reliability. Choose a higher horsepower engine and a robust, self-propelled system, often with larger rear wheels for better traction on slopes.
10 Frequently Asked Questions (FAQ) About Gas Lawnmowers
Q: How often should I change the oil in my gas mower?
A: Most manufacturers suggest changing the oil once per mowing season, or after every 25 to 50 hours of use.
Q: Can I use regular unleaded gasoline?
A: Yes, most modern mowers run fine on regular unleaded gas (87 octane). Never use fuel with more than 10% ethanol (E10) if your manual warns against it, as it can damage engine parts.
Q: What is the difference between a 2-cycle and a 4-cycle engine?
A: 4-cycle (or 4-stroke) engines use separate oil and gas, like a car. 2-cycle engines require you to mix the oil and gas together. Almost all modern push and riding mowers use cleaner, easier 4-cycle engines.
Q: How do I keep the blade sharp?
A: You should sharpen the blade at least once a year, usually before spring mowing starts. A dull blade tears the grass instead of cutting it cleanly.
Q: Why does my gas mower smoke a lot?
A: Excessive smoke often means the engine is burning oil. This happens if you accidentally put too much oil in, or if the engine is old and worn out.
Q: Are electric mowers better than gas mowers now?
A: Electric mowers are great for small yards and quiet operation. Gas mowers still offer more power and run time for very large or thick lawns.
Q: What does “front-wheel drive” mean on a self-propelled mower?
A: The engine powers the front wheels. This works well on flat ground but can struggle on steep hills where the weight shifts to the back.
Q: What is the safest way to store my mower for winter?
A: Run the mower until the gas tank is empty, or add a fuel stabilizer to the remaining gas and let the engine run for a few minutes to circulate the stabilizer.
Q: Should I buy a mower with an electric start?
A: Electric start uses a key or button instead of pulling a cord. It is a great convenience feature, especially if you have trouble pulling starter cords.
Q: How high should I set the cutting height?
A: Experts suggest you should never cut more than one-third of the grass blade height at one time. Set the height high for summer heat to help the grass stay healthier.
