Our take on the POWERSMART 21 Gas Self-Propelled 140cc B&S Engine Lawn B8721S2

The PowerSmart 21 is a gas walk-behind mower with a 140cc Briggs & Stratton engine and self-propelled drive, so you don't push it up slopes. It cuts a 21-inch swath, bags clippings in the collection box or mulches them back into the lawn. It suits homeowners with a mid-size yard who want a familiar gas mower without paying premium-brand money. Against rivals like the Honda HRN and Toro Recycler, it gives up some engine refinement and deck durability but covers the basics.

Questions and answers

Is the PowerSmart 21 good for a sloped yard?
The self-propelled drive pulls the mower forward, which helps on gentle slopes. On steep hills the weight of a gas mower still works against you.
Can it mulch as well as bag?
Yes. It has a mulching option and a collection box, so you can choose per cut. Mulching results are decent but not as fine as premium mulching decks.
What engine does it use?
A 140cc Briggs & Stratton engine. That brand is common, so parts and service are easy to find.
How does it compare with a Honda or Toro gas mower?
It costs less and covers the same basics: 21-inch cut, self-propulsion, bagging and mulching. The premium brands tend to start easier, run smoother and last longer.
What maintenance does it need?
Gas, engine oil changes, spark plug checks and blade sharpening. It also needs stabilizer or draining before winter storage.
Is it hard to assemble?
Assembly is mostly unfolding the handle and attaching the collection box. Expect to add oil and gas before the first start.
Where is the POWERSMART 21 Gas Self-Propelled 140cc B&S Engine Lawn B8721S2 cheapest?
At Walmart, for $389.00, as of our latest check.
