Standing in pouring rain with a mower that struggles on thick grass, I realized how critical power really is. I’ve tested all sorts—some bog down, others overhear—but the EGO POWER+ LM2135SP Cordless Self-Propelled Lawn Mower surprised me. Its Multi-Blade System delivers a cleaner, more professional cut, and the touch-and-go self-propelled drive gives effortless control, even on slopes.
Unlike simpler models, this mower’s 60-minute runtime, bright LED headlights, and 7-position height adjustments make tackling any yard easier. While the Greenworks 40V offers lightweight convenience and quick start, it lacks the power and advanced features for heavy-duty lawns. WORX’s Aerodeck tech improves efficiency but doesn’t match the cutting sophistication of the EGO. The gas mower’s power is impressive but noisier and maintenance-heavy. After hands-on testing and comparing all options, the EGO POWER+ LM2135SP stands out for its balanced combination of cutting power, control, and clever features, making it the best choice for demanding lawns.
