The MILWAUKEE® M18 FUEL™ 21" Self-Propelled Dual Battery Mower Kit meets the performance, durability, and ergonomic needs of landscape maintenance professionals. The optimized steel deck design paired with higher blade speed allows the battery-powered 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. Milwaukee REDLINK PLUS™ Intelligence offers total system communication between tool and battery for unmatched levels of performance, protection, and productivity. The advanced electronic package also delivers an instant throttle response on both the lawn mower blade and drive motors to reach full throttle in under 1 second, which increases control and productivity. The mower requires 2 M18™ REDLITHIUM™ Batteries for operation. When paired with the included 2 M18™ REDLITHIUM™ HIGH OUTPUT™ HD12.0 batteries, the 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 users to easily adjust their walking pace while in operation to increase control.
