Your Guide to Choosing the Right Gas Mower
Buying a new gas lawn mower can feel tricky. There are so many choices! This guide helps you pick the best one for your yard. Gas mowers offer power for big jobs. They need a little more care than electric ones, but they cut grass like a dream.
Key Features to Look For
When you shop, check these important features first. They decide how well the mower works for you.
Engine Power and Size
- Engine Size (CCs): Bigger yards need stronger engines. Look for engines around 140cc to 160cc for average lawns. Very thick or hilly yards might need 170cc or more.
- Engine Brand: Trusted brands like Briggs & Stratton or Honda often mean better reliability.
Cutting Deck Size
- Deck Width: This is how wide the mower cuts in one pass. Small yards (under a quarter acre) do well with 20-inch decks. Large yards benefit from 22-inch or wider decks. Wider decks save you time!
Starting Mechanism
- Pull Start vs. Electric Start: Most mowers use a pull cord. Electric start buttons make starting easy, especially if you have trouble pulling cords.
Drive Type
- Push Mower: You push these. They are great for small, flat lawns and cost less.
- Self-Propelled Mower: The engine moves the wheels for you. This is a lifesaver on hills or large lawns. Look for variable speed controls so you can walk at your own pace.
Important Materials and Construction
The parts a mower uses affect how long it lasts. Strong materials mean less worry about breakdowns.
Deck Material
- Steel Decks: Most common and very tough. They handle bumps well.
- Aluminum Decks: These are lighter and will never rust. They cost more money.
Wheels
- Big rear wheels make turning easier, especially on uneven ground. Plastic wheels break easily. Look for durable, thick plastic or even rubber wheels.
Factors That Improve or Reduce Quality
Some features make mowing easier. Others can cause headaches.
Quality Enhancers:
- Mulching Capability: Good mowers chop grass finely so it feeds your lawn nutrients instead of clumping up.
- Adjustable Cutting Height: You need to change the height for different grass types or seasons. Look for easy-to-use single-lever height adjustments.
- Washout Ports: Some decks have a hose connection. You attach a hose, turn the water on, and the deck cleans itself. This keeps the deck healthy.
Quality Reducers:
- Cheap plastic levers and handles often snap after a few seasons.
- Engines that require mixing oil and gas (2-stroke) are usually older technology and less user-friendly than modern 4-stroke engines.
User Experience and Use Cases
Think about your yard when you buy. A mower perfect for a tiny city yard might struggle on a farm.
- Small, Flat Yards: A simple, lightweight push mower works well. You save money and storage space.
- Medium Yards with Gentle Slopes: A standard self-propelled mower with good traction is ideal.
- Large Yards or Steep Hills: You need a high-powered engine and a wide deck. A self-propelled model with strong drive wheels is necessary.
Always check the noise level. Gas mowers are loud. If you have close neighbors, look for models specifically rated as quieter.
10 Frequently Asked Questions (FAQ) About Gas Mowers
Q: How often should I change the oil in my gas mower?
A: You should change the oil at least once per mowing season, or after every 25 to 50 hours of use, whichever comes first. Check your owner’s manual for the exact recommendation.
Q: What kind of gas should I use?
A: Most modern gas mowers use regular unleaded gasoline (87 octane). Never use gasoline that is more than 30 days old, as old gas causes starting problems.
Q: Do I need to mix oil and gas?
A: Most modern push and self-propelled lawn mowers use 4-stroke engines. You put oil in the oil dipstick hole and gas in the fuel tank separately. Only older or very small engines require mixing oil and gas.
Q: What is the difference between bagging and mulching?
A: Bagging collects the grass clippings in a bag attached to the mower. Mulching cuts the clippings into tiny pieces and drops them back onto the lawn to decompose naturally.
Q: How do I store my mower for the winter?
A: Always run the engine until it completely stops, or add a fuel stabilizer to the gas tank. Store the mower in a dry place, like a shed or garage.
Q: Can I use my gas mower on very tall grass?
A: Gas mowers can handle tall grass, but it slows them down. If the grass is very tall (over six inches), raise the cutting height first. Mow over it once high, then lower the deck and mow again a few days later.
Q: Are self-propelled mowers difficult to push if the drive system breaks?
A: Yes, they are heavier than push mowers. If the drive belt breaks, you must push the mower manually, which requires more effort.
Q: How do I keep the blades sharp?
A: You should sharpen the blades once a year, or whenever you notice the grass edges look ragged or brown after cutting. Many hardware stores sharpen blades for a small fee.
Q: Why won’t my gas mower start after I just filled it with gas?
A: This often means the carburetor is clogged by old fuel. Always use fresh gas. If it still won’t start, the spark plug might be dirty or wet.
Q: What safety gear is essential when using a gas mower?
A: Always wear safety glasses to protect your eyes from flying debris. Wear sturdy, closed-toe shoes. Ear protection is also highly recommended because gas mowers are very loud.
