- Is an 18-inch deck big enough for a half-acre lawn?
- It works but is slow: expect noticeably more passes than a 21-inch mower. For a half acre or more, a wider deck saves real time.
- Do I need to mix oil and gas?
- That depends on the engine. Many small self-propelled mowers use a four-stroke engine with a separate oil sump; two-stroke engines need pre-mixed fuel. Check the engine type before buying.
- How does self-propelled help on a slope?
- The drive turns the rear wheels so you guide rather than push. On steep hills, front-wheel drive can lose traction; rear-wheel drive grips better.
- What maintenance does a gas mower need?
- Change the oil, replace the spark plug and air filter, and sharpen the blade each season. Stale fuel is the most common cause of starting problems, so run the tank dry or use stabilizer before storage.
- When is the cheapest time to buy a gas mower?
- Late summer and early fall, when stores clear out seasonal inventory, usually bring the lowest prices. Spring is the most expensive time.
