- Small yards
- Budget
- Push
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.
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
