The Masterforce® 21-inch cordless self-propelled lawn mower with an included 5.0 amp-hour battery and rapid charger combines battery power with brushless technology to deliver clean, no-fume performance without the hassle of gas, oil, or maintenance and with the power equivalent of a 160cc gas engine. Enjoy up to 60 minutes of runtime and power at the push of a button. Adaptive cut technology automatically adjusts the cutting power based on turf conditions, or choose to maximize the blade speed by selecting the turbo button. The dual-port powerhead holds up to two batteries (additional batteries sold separately) and features auto switch technology that switches over automatically upon depletion of the first battery. This self-propelled, walk-behind mower gives you the option to bag, mulch, discharge, or leaf pickup. Select your ideal grass height with the seven-position single-point height adjustment. If you prefer mowing in the early morning or evening hours, high-intensity LED headlights provide the perfect solution. The rear wheel self-propelled system provides increased traction, and the EZ fold handles quickly fold and store vertically, making it ideal for compact spaces. This lawn mower and the included 5.0 amp-hour battery are compatible with all Masterforce® 80-volt batteries and tools.
