The Ultimate Buying Guide for Gas-Powered Lawn Mowers
Buying a gas-powered lawn mower can make yard work much faster. These powerful machines handle big yards and thick grass easily. This guide helps you pick the best one for your needs.
Key Features to Look For
Several features make mowing easier and the mower last longer. Look closely at these points before you buy.
Engine Power and Size
Engine size, measured in cubic centimeters (cc), tells you how strong the mower is. For small, flat yards, a 140cc engine works well. For large yards or hills, choose an engine of 160cc or more. A more powerful engine cuts tall, wet grass without stalling.
Drive Type (Self-Propelled vs. Push)
- Push Mowers: You walk behind and push the entire machine. They are lighter and cheaper. They work best on small, flat lawns.
- Self-Propelled Mowers: These mowers drive themselves forward. You just steer. They have different drive speeds. Self-propelled is a must-have for large yards or steep slopes.
Cutting Deck Width
The deck is the metal housing around the blade. A wider deck cuts more grass in one pass, saving you time. A 21-inch deck is standard. If your yard is very large, look for decks 22 inches or wider.
Grass Disposal Options
Mowers offer three ways to handle the clippings:
- Bagging: Clippings go into a rear bag you empty later.
- Mulching: The clippings get chopped very finely and drop back onto the lawn as natural fertilizer.
- Side Discharge: Long clippings shoot out the side chute.
Important Materials and Build Quality
The materials used affect how long your mower lasts and how well it handles bumps.
Deck Material
Most quality decks are made from heavy-gauge steel. Steel resists rust better than cheaper materials if the paint chips. Some premium mowers use heavy-duty aluminum decks. Aluminum is lighter and will never rust, but it costs more.
Wheel Quality
Wheels made of hard plastic can crack over time. Look for mowers with wheels made of durable, solid rubber or composite materials. For uneven yards, wheels with ball bearings roll much smoother.
Factors That Improve or Reduce Quality
Small details often separate a good mower from a great one.
Starting Mechanism
Modern mowers often feature “Easy Start” systems. These reduce the force needed to pull the starting cord. Some high-end models even have electric push-button start. Avoid models that require many hard pulls to start.
Adjustable Cutting Height
Quality mowers let you change the cutting height easily. Single-lever height adjustment is much faster than adjusting each wheel separately. This feature improves user experience significantly.
Engine Maintenance
A good engine will have an easily accessible air filter and spark plug. This allows for simple yearly tune-ups. If the maintenance parts are hard to reach, you might skip necessary care.
User Experience and Use Cases
Think about *how* you will use the mower when making your choice.
Maneuverability
If you have many trees or flower beds, you need a mower that turns easily. Front-wheel-drive self-propelled mowers often pivot better than rear-wheel-drive models. Push mowers are the most maneuverable but require more effort.
Storage
If you have limited garage space, look for mowers with “vertical storage” options. These mowers allow the handle to fold down so the machine stands upright, taking up less floor space.
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 after the first five hours of use (break-in period). After that, change the oil at least once per mowing season, or every 25 to 50 hours of use.
Q: What is the difference between a 2-cycle and a 4-cycle engine?
A: A 4-cycle engine (most common today) uses separate oil and gas, like a car. A 2-cycle engine mixes the oil directly into the gas. 4-cycle engines are generally quieter and require less maintenance.
Q: Is a self-propelled mower worth the extra cost?
A: Yes, if your yard is larger than a quarter acre or if you have any hills. It saves your energy greatly.
Q: What is the best blade for thick grass?
A: A high-lift blade is best. These blades move more air, creating a stronger vacuum that stands the grass up before cutting it cleanly.
Q: Should I leave the grass clippings on the lawn?
A: If you use a good mulching setting and do not cut more than one-third of the grass height, mulching is great. It feeds nutrients back into your soil.
Q: How do I prevent my mower from rusting?
A: Always store your mower in a dry shed or garage. Before long-term storage, clean any caked-on grass from the underside of the deck.
Q: What does “Variable Speed” mean on a self-propelled mower?
A: Variable speed means you can adjust the driving speed to match your walking pace, rather than being stuck at one set speed.
Q: Are electric start mowers more reliable than pull-start?
A: Electric starts are convenient, but they rely on a battery. Pull-starts are mechanically simple and are very reliable if the engine is maintained well.
Q: What is the easiest way to clean the spark plug?
A: First, disconnect the spark plug wire for safety. Then, use a wire brush to gently clean off any carbon buildup on the tip of the plug.
Q: When should I buy a riding mower instead of a walk-behind mower?
A: If your yard is over half an acre, or if you spend more than one hour mowing with a walk-behind, a riding mower will save you time and effort.
