Replace dangerous emissions, smells, hassles, and maintenance with Greenworks Pro 60V 21" Lawn Mower. The intelligent brushless motor technology provides constant, fade-free power equivalent to 150cc gas powered lawn mowers. Lightweight and quiet-running, this mower features SmartCut Technology that constantly monitors grass conditions, then automatically adapts to provide the perfect amount of power needed to get the job done; dual cutting blades that won't bog down in tall, wet, or thick grass. Lawn mower mows up to 0.5 acres on a single charge, and battery fully recharges in just 50 minutes; add extra battery into dual powerhead ports with automatic battery switchover for longer runtime. The heavy-duty steel cutting deck with seven-position, single-lever cutting height adjustment provides maximum airflow for excellent cuts, and features our four-in-one design for mulching, side discharge, or bagging, with added turbo button for better lift when picking up leaves. With hassle-free, push button starts, you'll get to work fast, with no priming, no choke, and no pull cord. Other features include LED headlights, oversized 10" rear and 8" front tires, and EZ Fold handles for space-saving vertical storage.
