Our M18 FUEL™ 21" Self-Propelled Dual Battery Mower meets the performance, durability, and ergonomic needs of landscape maintenance professionals. The optimized steel deck design paired with higher blade speed allows our cordless electric lawn mower to achieve superior airflow and increased lift to deliver the best cut quality in mulching, bagging, and side discharge applications. The POWERSTATE™ Brushless Motor delivers more max torque than 200cc gas to take on the most demanding mowing applications. The REDLINK PLUS™ Intelligence has total system communication between the tool and battery for unmatched levels of performance, protection, and productivity. The advanced electronic package also delivers an instant throttle response on both the blade and drive motors to reach full throttle in under 1 second, which increases your control and productivity. The electric mower requires 2 M18™ REDLITHIUM™ Batteries for operation. When paired with the recommended 2 M18™ REDLITHIUM™ HIGH OUTPUT™ HD12.0 batteries (not included), the self-propelled electric lawn mower delivers up to 60 minutes of runtime, allowing up to 1/2 acre of cutting when removing 1" of grass at a 3 MPH self-propelled pace. The Variable Speed Self-Propelled Mower offers speeds between 0 - 4 MPH, and the Active Speed Management Paddles allow you to easily adjust your walking pace while in operation to increase control.
