The consensus
What reviewers found
Synthesized across the trust-weighted source mix below.
Across the reviewers we read, the PowerSmart 21-inch rear-wheel-drive is the slope-oriented pick, since reviewers consistently favor RWD over front-wheel drive on inclines for traction. The Home Depot listing touts the 170cc OHV engine and all-steel deck, and r/lawnmowers owners report it 'runs and cuts very well' and 'starts on the first pull 99 percent of the time,' with one noting the self-propel is 'really fast, almost too fast to keep up with.' The disagreement here is the most pronounced of any pick. A summarized Facebook group thread says 'most commenters strongly advise against Power Smart, citing poor quality and reliability issues,' and community members on r/lawnmowers describe PowerSmart units as cheap and low-end.

The disagreement here is the most pronounced of any pick. A summarized Facebook group thread says 'most commenters strongly advise against Power Smart, citing poor quality and reliability issues,' and community members on r/lawnmowers describe PowerSmart units as cheap and low-end. There's no independent lab data, and the rating base is modest at 4.0 across roughly 119 ratings. For a budget RWD mower aimed at sloped yards the upside is real, but the reliability concerns are equally well documented—so buyers should weigh both honestly.
- Powered By A Reliable Ohv Engine
- Equipped with a powerful 170cc OHV engine, known for its smooth start-up, consistent performance, and long-term durability—ideal for tough mowing jobs.
- 21-Inch Cutting Width For High Efficiency
- The robust steel deck covers a wide 21-inch path, reducing mowing time and making it perfect for medium to large yards.
- 3-In-1 Function
- BAGGING, MULCHING & REAR DISCHARGE: Switch easily between modes: collect clippings in the 1.4-bushel bag, mulch to nourish your lawn, or rear-discharge for quick and efficient mowing.
- 6-Position Height Adjustment
- Quickly adjust the cutting height from 1.5"" to 3.9"" with a single lever to match grass length, season, or preferred lawn look.
- Self-Propelled With Large Rear Wheels
- Rear-wheel drive and 10"" large rear wheels offer excellent traction and maneuverability on slopes or uneven terrain.
