PowerSmart 21" Gas Push Mower vs Troy-Bilt TB120 Gas Push Mower

Both are basic 21-inch gas push mowers with pull starts and steel decks, so the choice comes down to engine and adjustability. The PowerSmart 144cc has a documented 6-position height range of 1.5 to 3.9 inches and three cutting modes, which suits renters and small-lot owners who want simple, low-cost cutting. The Troy-Bilt TB120 uses a 140cc engine and has a long reputation for easy first-pull starts and US-built assembly; owners of the brand line report solid reliability, but the mower is heavier and less adjustable on paper. Buy the PowerSmart for the wider height range and mulching setup; buy the Troy-Bilt if brand support and proven starting matter more.

• Choose the PowerSmart 21" 144cc if you want a light 62 lb push mower with six cutting heights, mulching and a two-year warranty.
• Choose the Troy-Bilt Gas Push Mower if you prefer a proven US-built brand with a 140cc engine and easy first-pull starts.
