The Ultimate Buying Guide for Your New Gas Lawnmower
Choosing the right gas lawnmower makes yard work much easier. Gas mowers offer power for big lawns. This guide helps you pick the best one for your needs.
Key Features to Look For
Several features make a lawnmower great. Look closely at these important parts before you buy.
Engine Power and Type
- Engine Size (CCs): Bigger yards need more power. Look for engines rated higher in cubic centimeters (CCs) for thick or tall grass. Smaller yards need less power.
- Engine Brand: Trusted brands like Briggs & Stratton or Honda often mean better reliability and easier repairs.
Cutting Performance
- Deck Size: This is how wide the mower cuts in one pass. Wider decks (21 inches or more) finish large lawns faster. Narrower decks work better in tight spaces.
- Cutting Height Adjustments: You need to change how high or low the grass is cut. Look for easy-to-use, single-lever adjustments rather than multiple wheel adjustments.
Propulsion System
- Self-Propelled vs. Push: Self-propelled mowers move themselves forward. This feature saves you a lot of energy on hills or large areas. Push mowers are cheaper and good for small, flat yards.
- Drive Wheel Type: Rear-wheel drive often provides better traction, especially when bagging clippings.
Important Materials and Durability
The materials used determine how long your mower lasts. Strong materials mean less worry about breakdowns.
Deck Material
- Steel Decks: Most common and very strong. They resist impacts well.
- Aluminum Decks: These are lighter and naturally resist rust, but they might cost more.
Wheel Construction
Plastic wheels break easily. Look for mowers with **durable, high-quality plastic or, better yet, metal wheels** for longevity, especially if your yard has rough patches.
Factors That Improve or Reduce Quality
Small details often separate a good mower from a great one.
Quality Boosters
- Washout Ports: These allow you to connect a hose to the deck to clean grass buildup easily. This keeps the blades working efficiently.
- Three-in-One Functionality: The ability to bag clippings, mulch them (chop them fine), or discharge them out the side offers flexibility for different lawn conditions.
Quality Reducers
- Difficult Starting Mechanisms: If the pull cord feels stiff or requires many yanks, the starting process becomes frustrating. Look for electric start options if possible.
- Flimsy Handlebars: Thin metal or plastic handles vibrate a lot and feel cheap. Sturdy handles improve your control and comfort.
User Experience and Use Cases
Think about how and where you will use the mower. This guides your final decision.
Maneuverability
If your yard has many trees, flower beds, or tight corners, you need a mower that turns easily. Swivel front wheels often help with navigation.
Storage Needs
Do you have limited space in your garage or shed? Many modern mowers feature **folding handles** that allow them to be stored vertically or compactly. Check the dimensions before buying.
Noise Level
Gas mowers are loud. While you cannot eliminate the noise, some newer engines run slightly quieter than older models. Consider if you need to mow early in the morning.
10 Frequently Asked Questions (FAQ) About Gas Lawnmowers
Q: What is the best time to buy a gas lawnmower?
A: You often find the best deals late in the summer or in the fall when stores clear out old inventory for winter.
Q: How often should I change the oil in my gas mower?
A: Most manufacturers suggest changing the oil after the first five hours of use, and then once per season or every 25 to 50 operating hours after that.
Q: What is mulching, and why should I use it?
A: Mulching chops the grass clippings into tiny pieces. These tiny pieces fall back onto the lawn, acting as natural fertilizer. It saves you the hassle of bagging.
Q: Can I use regular gasoline in my mower?
A: Most modern mowers use regular unleaded gasoline. Always check your owner’s manual to confirm the required octane rating.
Q: What is the difference between a push mower and a self-propelled mower?
A: A push mower requires you to supply all the forward movement. A self-propelled mower uses the engine to drive the wheels, making it easier for you to walk behind it.
Q: How do I keep my mower running well during winter storage?
A: You should run the fuel tank dry or add a fuel stabilizer to prevent the gas from breaking down and clogging the carburetor over the winter months.
Q: Are electric start mowers reliable?
A: Yes, electric start mowers are very convenient. They use a small battery to turn the engine over, eliminating the need for a pull cord, but they might require battery charging.
Q: What size engine do I need for a half-acre yard?
A: For a half-acre yard, a mower with an engine around 140cc to 160cc is usually powerful enough, especially if the yard has slopes.
Q: How often do I need to sharpen the blade?
A: Sharpen your mower blade at least once per mowing season. If you cut thick grass often, you might need to sharpen it twice a year.
Q: What is the warranty usually like on a new gas mower?
A: Most manufacturers offer a basic warranty covering the engine and the deck for about two to three years. Always read the fine print regarding what voids the warranty.
