Buying Guide
- — For compact yards, a 21-inch deck balances coverage with maneuverability. Gas push mowers offer more power for tougher grass, while reel mowers provide quiet operation and zero emissions.
- — Gas engines provide consistent power for varied grass conditions. Self-propelled models reduce push effort on slopes or thicker lawns; push-only models are lighter and simpler to maintain.
- — 3-in-1 mowers handle clippings in different ways. Choose based on whether you prefer natural fertilization (mulching), tidy bagging, or quick side discharge for thick growth.
- — Steel decks tend to be more durable than plastic but may add weight. Consider storage space and climate exposure when selecting a model.
- — Gas models require more routine maintenance (oil, air filter, spark plug) and starting procedure. Reel mowers need regular blade sharpening; electric options require battery upkeep.
- — Foldable or compact designs help in tight garages. Self-propelled units are heavier; plan for lifting if storage height is restricted.
