The consensus

What reviewers found

Synthesized across the trust-weighted source mix below.

Across the reviewers we read, the AMERISUN 21-inch is the lowest-priced dedicated push mower in this pool and carries a 4.2-star average across roughly 74 ratings. It's listed at Best Buy—a high-trust retailer in our framework—which highlights the 21-inch steel deck and heavy blade for faster coverage, and a related r/lawnmowers thread notes a buyer was 'amazingly impressed by the quality' of a comparable budget unit, with the main gripe being a pull cord that broke. The clearest limitation is terrain.

What reviewers liked

  • Lowest price among dedicated push mowers here
  • Listed at high-trust retailer Best Buy with a 4.2-star average
  • 21-inch steel deck covers more ground per pass than 18-inch rivals

Where it falls short

  • Walmart reviewer says plastic wheels make hills impractical
  • Low review volume (~74) limits confidence
  • Base configuration lacks full bagging; modest 144cc engine

Across the reviewers we read, the AMERISUN 21-inch is the lowest-priced dedicated push mower in this pool and carries a 4.2-star average across roughly 74 ratings. It's listed at Best Buy—a high-trust retailer in our framework—which highlights the 21-inch steel deck and heavy blade for faster coverage, and a related r/lawnmowers thread notes a buyer was 'amazingly impressed by the quality' of a comparable budget unit, with the main gripe being a pull cord that broke.

The clearest limitation is terrain. A Walmart reviewer warned that 'the plastic wheels make it impossible to mow on a hill,' which matters for anyone with sloped property. With a 2-in-1 deck (mulch and side discharge) rather than full bagging on the base model and a modest 144cc engine, it's best understood as a no-frills push mower for small, flat lawns. Review volume is thin, so confidence is lower than the higher-count picks, but the value and Best Buy presence keep it in the list.
