Self‑propelled gas: 22 in vs 21 in and engine options

Shoppers comparing gas self‑propelled mowers often ask about deck width and drive type. A 22 in deck covers a slightly wider path than a 21 in deck. Rear‑wheel drive can aid traction on mild slopes.

• PowerSmart 22 in 170cc Self-Propelled V8622S: 22 in steel deck, 170cc 4‑stroke OHV engine, rear‑wheel drive, 6 cutting heights (about 1.5–3.9 in), roughly 69 lb, 3‑in‑1 discharge management. Suits medium lawns (e.g., up to around 1/2 acre) and mild slopes.
• PowerSmart 21 in 140cc Self-Propelled B8721S1: 21 in class deck (20 in listed blade), Briggs & Stratton E550 140cc, 6 heights (about 1.5–3.9 in), 7 in front/10 in rear wheels, 60 L catcher. Appeals to buyers who prefer a Briggs & Stratton engine in a slightly smaller chassis.

21 in gas push: value vs Briggs & Stratton

Both options give you a familiar 21 in footprint with single‑lever height control. Choose based on engine preference and whether you want full 3‑in‑1 cut handling.

• PowerSmart 21 in 144cc Push 3-in-1 DB8621P: 3‑in‑1 (side discharge, mulch, rear bag), 6 heights (about 1.5–3.9 in), steel ST14 deck, grass bag around 15.8 gal. Emphasizes value.
• PowerSmart 21 in 140cc Push B8721P: Briggs & Stratton 550EX 140cc engine, 6 heights (about 1.5–3.9 in). Trades up to a name‑brand engine.

Compact gas push: 17–18 in for small yards and tight spots

Smaller decks are easier to maneuver around landscaping and in narrow gates. Pick 3‑in‑1 if you want rear bagging; pick 2‑in‑1 for simplest operation and lower weight.

• PowerSmart 17 in 144cc Push 3-in-1 DV8618P/V8617P: 3‑in‑1 cutting, 6 heights (about 1.5–3.9 in), 7 in front/8 in rear wheels, 1.4‑bushel catcher.
• PowerSmart 18 in 144cc Push 2-in-1 DB8618C: 2‑in‑1 (side discharge + mulch), 5 heights (about 1.5–3.9 in), Runtong RV145‑S engine, about 44.4 lb product weight.

Electric choices: corded simplicity or 40V cordless kit

If you can mow within reach of an outdoor‑rated extension cord, a corded mower minimizes maintenance. If you prefer untethered mowing and want to start a battery platform, look at the 40V combo.

• PowerSmart 14 in 15A Corded Mower DB8015: 14 in deck, 2‑in‑1 (mulch + bag), 6 heights from about 1.0–3.0 in, 10‑gal bag, polypropylene deck.
• PowerSmart 40V 17 in Mower + 40V Blower MB2480C: 17 in brushless mower with 3‑in‑1 cutting plus a 40V blower (up to 450 CFM/125 MPH). It’s part of the PowerSmart 40V platform. For planning purposes, a comparable 17 in 40V mower in this line lists up to about 25 minutes of runtime with a 4.0Ah battery; actual time varies with grass height and conditions.

Accessory: cover your mower between cuts

Protecting a walk‑behind from dust and weather can extend its appearance and help keep controls clean.

• PowerSmart Lawn Mower Cover: Universal‑style cover offered by PowerSmart. Check your mower’s dimensions to confirm fit on 21–22 in walk‑behinds before you buy.
