The consensus
What reviewers found
Synthesized across the trust-weighted source mix below.
Across the reviewers we read, the Greenworks 40V 16" push mower is the budget consensus pick, backed by an unusually large review base — roughly 11,970 Amazon ratings at a 4.2 average. Two high-trust r/lawncare threads stand out: one owner ran theirs reliably for about 10 years off the included 4.0 and 2.0Ah batteries, and another said after extensive research Greenworks was the value winner by far. The limitations are well-documented and honest.
What reviewers liked
- Enormous review base (~11,970 Amazon ratings) and two high-trust r/lawncare value endorsements
- One r/lawncare owner reported ~10 years of reliable service
- Lightweight, easy to start and maneuver; ties into the 75+ tool Greenworks ecosystem
Where it falls short
- Lowest Amazon average here (4.2) among the ranked picks
- Multiple owners report the battery dies faster in long grass, sometimes mid-mow
- 16" deck and 1/3-acre rating limit it to smaller yards; not self-propelled

The limitations are well-documented and honest. The most common complaint across r/Costco and a Greenworks community group is that the battery dies faster in longer grass, sometimes before finishing the lawn — owners repeatedly recommend keeping the second battery charged. It's lightweight and easy to handle and start, which beginners and small-lot owners appreciate, but the 16" deck and 1/3-acre rating make it best for smaller yards.
The trust-weighted picture is a no-frills, lightweight mower that does the job affordably and ties into the broad Greenworks battery ecosystem. It won't match the power or runtime of the 60V/80V models, but for a small lawn on a budget, the consensus is solidly positive.

- [3-YEAR WARRANTY]
Works great and does a good job. Only issue is that in longer grass the battery dies faster. So I always keep the other charged.
I had a Greenworks mower for about 10 years that ran fine off the included 4.0 and 2.0 mah batteries. I've been super happy with mine. ...
