The Essential Buying Guide for Your Small Gas Lawn Mower
Choosing the right small gas lawn mower makes yard work much easier. These mowers are great for smaller yards, tight corners, and homeowners who don’t want the hassle of cords or heavy batteries. This guide helps you pick the best one for your needs.
1. Key Features to Look For
When you shop, focus on these important features. They determine how well the mower works and how easy it is to use.
Engine Power and Size
Small gas mowers usually have engines between 125cc and 160cc. For a small to medium yard (under a quarter acre), a smaller engine is fine. Bigger engines offer more power for thick or wet grass. Check the horsepower (HP) rating; more HP means it cuts tougher grass easily.
Cutting Width (Deck Size)
The deck size tells you how wide a strip of grass the mower cuts in one pass. Small mowers often have decks between 18 and 21 inches. A smaller deck (18 inches) turns quickly around trees. A larger deck (21 inches) finishes the job faster on a slightly bigger patch of grass.
Drive System
Small mowers are usually “push” mowers, meaning you have to push them yourself. This is good exercise for tiny yards. If your yard has small hills, consider a self-propelled model. Self-propelled mowers move the wheels for you, saving your energy.
Bagging, Mulching, and Side Discharge
Think about what you want to do with the grass clippings:
- Bagging: Collects clippings in a bag for easy disposal.
- Mulching: Chops grass finely and drops it back onto the lawn, feeding the soil.
- Side Discharge: Shoots clippings out the side.
Many good mowers let you switch between these three options.
2. Important Materials
The materials used affect how long the mower lasts and how much it weighs.
Deck Material
Most quality decks are made of steel or aluminum. Steel decks are strong and less expensive. Aluminum decks resist rust better and weigh less, making the mower easier to push, but they cost more.
Engine Quality
Look for trusted engine brands like Briggs & Stratton or Honda. These engines generally start easier and need less maintenance over time.
Wheels
Plastic wheels break easily. Look for mowers with durable wheels, preferably made of hard plastic or rubber, especially if you have bumpy ground. Rear wheels are often taller than front wheels, which helps when you turn or go over uneven spots.
3. Factors That Improve or Reduce Quality
Certain features make a mower a better investment.
Ease of Starting
A good mower starts quickly, usually on the first or second pull of the cord. Some premium models offer electric start buttons, which eliminate pulling altogether.
Adjustable Cutting Height
You must adjust the blade height for different seasons. Look for mowers with a single-lever adjustment. This lets you change all four wheels’ heights at once. Mowers with four separate levers are slower to set up.
Maintenance Access
Quality mowers allow you to easily access the spark plug and air filter. If maintenance is hard, you might skip it, which shortens the mower’s life.
4. User Experience and Use Cases
Consider where and how often you will use the mower.
Small City Lots
If your yard is small and mostly flat, a basic, lightweight 18-inch push mower with good mulching capability works perfectly. You need maneuverability more than raw power.
Yards with Obstacles
If you have many flowerbeds, patios, or trees, choose a mower with a smaller turning radius. High rear wheels help you pivot the mower around obstacles quickly.
Storage Space
Small mowers should store easily. Check if the handle folds down. This feature lets you store the mower upright in a small shed or against a garage wall.
10 Frequently Asked Questions (FAQ) About Small Gas Lawn Mowers
Q: How much gas does a small mower use?
A: Small mowers are very fuel-efficient. They typically use less than one gallon of gas for several hours of continuous mowing on a small yard.
Q: Are small gas mowers very loud?
A: Yes, all gas mowers make noise. Look for models that specifically mention a “low-noise muffler” if noise is a major concern.
Q: What kind of gas should I use?
A: Most small mowers run best on regular unleaded gasoline (87 octane). Always check the owner’s manual before adding fuel.
Q: How often must I change the oil?
A: You should change the oil after the first five hours of use, and then once per mowing season, or every 50 hours of use.
Q: Can I use a small mower on tall grass?
A: They can handle moderately tall grass, but if the grass is overgrown (over 6 inches high), you should cut it in two passes: one high cut, then a second lower cut.
Q: What is the benefit of a steel deck over aluminum?
A: Steel decks are generally tougher against impacts, like hitting a large rock. Aluminum decks weigh less and do not rust.
Q: Is a self-propelled mower worth the extra cost for a small yard?
A: If your yard is perfectly flat, no. If you have any slopes or fatigue easily, yes, the self-propel feature saves significant effort.
Q: How do I winterize my small gas mower?
A: Before storing it for winter, you should either run the tank completely dry or add a fuel stabilizer to the remaining gas.
Q: What height setting should I use for the first cut of spring?
A: Set the mower to its highest setting for the first cut of spring. This avoids stressing the grass crown after winter dormancy.
Q: How heavy are these mowers usually?
A: Small push mowers typically weigh between 50 and 70 pounds. This weight makes them sturdy enough for good cutting but manageable to push.
