Gas mowers still win on uninterrupted runtime and power for larger or hilly lawns. We compared engine displacement, drive type, and deck specs rather than hands-on testing. Match a gas push mower to flat small yards and a self-propelled model to big or sloped lots.
Honda's HRN216VKA brings a 166cc engine, twin-blade cutting, and variable self-propel; on specs it suits larger or hilly yards where uninterrupted runtime beats battery convenience.
- Large yards
- Hills
- Self propelled
Pros
- Gas engine plus variable Smart Drive self-propel handles large lawns and hills without runtime anxiety
- Twin-blade MicroCut system is designed for finer clippings and denser bagging on the spec sheet
- Refuel-and-go operation avoids the recharge downtime that limits single-battery mowers
Cons
- Needs gas, oil changes, air filter, and off-season fuel care that electric models skip
- Emissions, noise, and pull/choke starting are drawbacks versus push-button battery units
- Near $600 it costs more than most gas push mowers and many battery push mowers
A budget 21-in gas push mower with an auto-choke 140cc engine; on specs it fits flat quarter-acre yards where low upfront cost matters more than self-propel or electric convenience.
- Small yards
- Budget
- Push
Pros
- Auto-choke 140cc engine starts without priming or choke fiddling on the spec sheet
- Low-$200s price makes it one of the cheaper ways into a full-size 21-in gas deck
- 3-in-1 deck and 6 height positions cover normal suburban mowing needs
Cons
- Push-only design is tiring on any slope or in thick grass
- Smaller 140cc engine has less headroom than 160cc+ mowers for tall, wet turf
- Still carries gas maintenance and storage chores that battery push mowers avoid

Frequently Asked Questions
- Do I need self-propelled or push gas?
- On specs, push gas mowers are lighter and cheaper and fine for flat lots under about a quarter acre. Self-propelled models add a driven transmission that helps on hills, thick grass, and larger areas.
- How much engine size do I need?
- For most 21-in residential mowers, 140-160cc handles normal turf. Larger 160cc+ engines like Honda's GCV170 give more headroom for tall or dense grass and reliable bagging.
