20" Self Propelled Lawn Mower,3-in-1 Walk-Behind Mower

The PowerSmart 20-inch cordless lawn mower delivers battery-powered cutting for homeowners who want to maintain their yards without gas fumes or engine maintenance. Built around a 40V power system and a rear-wheel self-propelled mechanism, it takes the physical effort out of mowing across larger or hilly properties. Large 10-inch rear wheels paired with 7-inch front wheels keep movement steady around garden borders and uneven terrain.

Cutting flexibility is one of the mower's strongest practical benefits. Its 20-inch deck lets you choose between side discharge for taller grass, mulching to return clippings to the turf, or collecting up to 1.4 bushels of clippings in the rear mesh catcher. A single ergonomic lever adjusts all four wheels at once, giving you 6 distinct cutting height positions ranging from 1.5 inches up to 3.9 inches.

The mower runs at 2,900 RPM and is powered by two 40V 4.0Ah batteries. The battery compartment features one active port and a secondary storage slot, allowing you to carry the spare battery directly on the machine. When work is done, quick-release folding knobs collapse the handle so the unit can stand fully upright, cutting down its garage storage footprint by up to 70 percent.

There are a few operational trade-offs to keep in mind. While having an onboard storage slot keeps your second battery close at hand, you will need to manually switch the packs between the active port and the storage slot when the first drains. In addition, the included smart charger takes 150 minutes to recharge a battery, so planning your mowing schedule around charging times is necessary.

Verdict: The PowerSmart 20-inch cordless mower is a solid choice for homeowners looking for a quiet, self-propelled walk-behind machine that handles slopes easily. Its compact vertical storage and versatile 3-in-1 grass management make it well-suited for residential lawn care.
