PowerSmart 21" Gas Push Mower vs Yard Machines 02B 20" Gas Push Mower

The PowerSmart is the more versatile mower: it bags, mulches and side-discharges, has a wider 21-inch cut and six height settings, and its 4.0 rating from over 3,300 owners edges out the Yard Machines. The Yard Machines counters with a proven Briggs & Stratton engine, arrives fully assembled and suits small flat yards on a tight budget. Buy the PowerSmart if you want mulching and bagging; buy the Yard Machines if you want a simple, dependable side-discharge cut and the least setup.

  • Choose the PowerSmart 21" if you want three cutting modes, a wider deck and more height choices for a medium yard.
  • Choose the Yard Machines 02B if you have a small flat lawn and want a Briggs & Stratton engine with no assembly.

What reviewers say

  • 4 / 53,325 ratings

What people mention
  • StartingMixedSome owners say it starts easily; others report repeated pulls, especially after storage.
  • Cut qualityPraisedBuyers say it cuts evenly and mulches clippings well.
  • WeightCriticisedAt 62 lbs, owners find it heavy to push and lift.

Yard Machines 02B 20" Gas Push Mower

  • 3.8 / 52,500 ratings

Ratings average 3.8 out of 5 from about 2,500 buyers, which fits a budget mower that starts and cuts reliably but feels basic. Owners tend to like the price and the simple engine and dislike the lack of self-propel and mulching.

What people mention
  • Push effortCriticisedOwners say pushing it through thick grass or up a slope is tiring because it is not self-propelled.
  • StartingPraisedBuyers report the Briggs & Stratton engine usually starts within a few pulls.
  • Cut qualityMixedIt cuts fine on flat, regular lawns, but the three height settings leave gaps for uneven turf.
  • MulchingCriticised

Questions and answers

Which is better for mulching?
The PowerSmart. It has a mulch plug and a deep dome deck designed for it. The Yard Machines is side-discharge only, so clippings go back on the lawn only by discharge.
Which has the better engine?
The Yard Machines uses a Briggs & Stratton 300e series engine, a widely serviced brand with easy parts access. The PowerSmart's 144 cc engine is larger in displacement but less established.
Which is easier to set up?
The Yard Machines. It ships fully assembled and you only unfold the handle. The PowerSmart requires some assembly before first use.
Which cuts a large yard faster?
The PowerSmart, with its 21-inch deck versus 20 inches. Both are push mowers, so neither is suited to steep or very large lawns.
Is the PowerSmart worth stepping up to?
Yes if you want bagging, mulching and finer height control. If you only side-discharge a small flat lawn, the Yard Machines covers that with less setup.
Which lasts longer?
Both carry a 2-year warranty and steel decks. The Yard Machines' Briggs & Stratton engine has the better track record for parts and service, while the PowerSmart's extra modes add parts that can wear.
