Our take on the PowerSmart 21 in. 140cc Briggs & Stratton 3-in-1 Rear Wheel Drive Lawn Mower

The PowerSmart 21-inch is a gas push mower with a 140cc Briggs & Stratton engine and a 3-in-1 deck: bag, mulch or side discharge. Rear-wheel drive pulls it up slopes and through thick grass, and the 21-inch deck suits most suburban lots. The best new price was $365 at eBay as of November 5, 2026, with five stores listing it new.

Questions and answers

Is the PowerSmart 21-inch worth it over a cheaper push mower?
If your yard has a slope or you mow tall grass, the rear-wheel drive is the main reason to pay more. On flat ground a front-wheel or push mower does the same job for less.
What comes in the box?
The mower ships partly assembled with the engine, deck, handle and grass bag. You add the oil and gas yourself; the manual lists the oil type.
Does it mulch well?
Yes. The 3-in-1 deck includes a mulch plug, and the 21-inch deck handles normal grass fine. Mulch best when you cut no more than a third of the blade height.
How does it compare with a Honda or Toro 21-inch?
Those brands cost more but often add electric start and better warranty coverage. The PowerSmart's edge is the lower price with a Briggs & Stratton engine.
When is the price lowest?
Gas mowers usually drop in late summer and early fall as stores clear inventory. The best new price was $365 at eBay as of November 5, 2026.
