Comparing the PowerSmart Lawn Mower Lineup
Cordless buyers can choose between 40V and 80V platforms with brushless motors and steel decks. The PowerSmart 17-Inch 40V Steel Deck Push Mower uses a 4.0 Ah battery for yards up to 1/8 acre. If you manage larger lawns up to half an acre, the PowerSmart 21-Inch 80V Push Lawn Mower provides higher battery voltage and a wider cut.
For gas equipment, drive type and mowing function separate the lineup. Rear-wheel self-propelled options like the PowerSmart 22-Inch Gas Self-Propelled Lawn Mower handle uneven terrain and offer 3-in-1 grass disposal. If your lawn is flat, manual push units like the PowerSmart 18-Inch 144cc Gas Push Mower provide focused side discharge without mechanical drive parts.
Where PowerSmart Fits Your Lawn Needs
PowerSmart focuses strictly on walk-behind mowers, spanning from 17-inch compact units up to 22-inch steel-deck models. The lineup covers manual-push and self-propelled setups weighing between 28.1 and 75 pounds. Gas displacements reach from 125cc to 170cc, while battery models span 40V to 80V.
You will notice clear equipment gaps. None of the listed mowers feature integrated headlights or alternate lighting options. All units share standard walk-behind frames, with no riding, zero-turn, or robotic designs available. The range also caps cutting widths at 22 inches, and self-propelled drive remains absent from the cordless options.

How to Choose a PowerSmart Mower
-
Match Drive Type to Terrain
Assess your lawn slope before selecting a drive system. Push models require full manual effort, which suits flat turf and saves overall equipment weight. If your lawn includes inclines, thick grass, or rough surfaces, pick a self-propelled model with rear-wheel assist. The PowerSmart 22-Inch Gas Self-Propelled Lawn Mower uses drive wheels to reduce pushing fatigue on uneven grades. Check the drive type spec on the listing. Manual push setups remain easier to navigate through cramped corners, while self-propelled drives protect your legs and back across expansive, hilly ground.
-
Select Deck Cutting Width
Compare deck width specifications against your property layout and storage space. Narrower 17-inch and 18-inch decks fit through standard yard gates, navigate garden beds easily, and store inside compact sheds. Broader 21-inch and 22-inch cutting widths remove more grass in fewer passes, saving time on open turf. Choose the PowerSmart 18-Inch 144cc Gas Push Mower if you need agile maneuvering around obstacles. If you manage wide, unobstructed lawns, prioritize 21-inch or 22-inch decks. Measure your narrowest fence gate before picking a cutting width to ensure clear passage during mowing.
-
Choose Clipping Disposal Options
Examine the mowing function spec to see how the deck manages cut grass. Side-discharge models spread clippings across your lawn, which works well for taller growth or utility areas. Versatile 3-in-1 machines provide mulching, side discharge, and rear bagging options in one deck. The PowerSmart 21-Inch 3-in-1 Gas Push Mower lets you bag clippings for clean walkways or mulch them back into your turf for soil nutrients. If you want pristine turf without loose debris, select a model that supports bagging. Choose dedicated side discharge if you prefer basic maintenance without emptying containers.
-
Evaluate Cordless Battery Voltage
Check the voltage rating when choosing a battery-powered mower. Lower 40V systems supply adequate energy for small properties with lighter mowing demands. High-voltage 80V configurations deliver greater power to the brushless motor, spinning blades firmly through dense growth. The PowerSmart 21-Inch 80V Push Lawn Mower pairs higher voltage with a full-sized 21-inch deck for properties up to half an acre. If you cut modest yards, a 40V tool keeps battery weight low. For thicker turf, larger cutting paths, or elevated cutting speeds, choose an 80V motor to maintain steady cutting performance under load.
-
Account for Overall Weight
Review the listed machine weight before buying to ensure comfortable handling. PowerSmart steel-deck mowers span from under 30 pounds up to 75 pounds. Heavier machines stay planted on uneven ground but demand physical effort when turning, pulling backward, or lifting into storage. The PowerSmart 17-Inch 40V Steel Deck Push Mower weighs 39.7 pounds, making it easy to steer around landscape borders. Push mowers weighing over 60 pounds can tire your arms quickly across rolling terrain. Choose a lighter chassis if you mow tight spaces, or select self-propelled mechanics if you choose a heavier frame.
