The Worx Nitro WG753 40V Power Share Cordless 21" Self-Propelled Lawn Mower with Rear Wheel Drive and 2X 5.0Ah Batteries has a highly-efficient brushless motor running 50% longer, churning out 25% more power, and providing 10% more life than brushed motors. With two high-capacity Power Share PRO batteries, this self-propelled mower is a worthy replacement to gas mowers. And does so without any of the drawbacks of gas, like the cost, mess, fumes, excessive volume, or extra maintenance. Full of quality-of-life features, like rear-wheel drive with a variable-speed control so the user can pick a pace that’s comfortable for them. Single-lever height adjustments and mode changes make switching between cutting heights (7-positions, 1.6 in.-4 in.) and cutting modes (bag/mulch/side-discharge) quick and easy. LED lights provide greater visibility when mowing at dusk or in other low-light conditions. Auto-Intellicut™ technology increases the speed of the blades when it detects thicker grass, then slows them back down when the mowing gets easier to conserve battery usage. And the one-touch fully-collapsible handle makes for compact, stand-up storage in the garage. The bag capacity is 2 Bushels, the wheels are 8 in. (front) and 10 in. (rear). The durable steel cutting deck is a wide 21 in. (20 in. cutting width) and great for lawns with rough terrain, and features Nutricut™ dual-stage mulching capabilities to return both water and nutrients back to your lawn.
