Our M18 FUEL™ 21" Dual Battery Self-Propelled Mower Kit meets the performance, durability, and ergonomic needs of landscape maintenance professionals. The optimized steel deck design, combined with higher blade speed, enables the MILWAUKEE® 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 maximum torque superior to that of a 200cc gas engine to tackle the most demanding mowing applications. REDLINK PLUS™ Intelligence enables full communication between the tool and battery, providing unbeatable levels of performance, protection, and productivity. The advanced electronic package also offers instant throttle response on both the blade and drive motors to reach full throttle in under 1 second, increasing your control and productivity. The mower requires 2 M18™ REDLITHIUM™ batteries to operate. When paired with the 2 included M18™ REDLITHIUM™ HIGH OUTPUT™ HD12.0 batteries, the lawn mower provides up to 60 minutes of runtime, allowing it to cut up to 1/2 acre by removing 1 inch of grass at a self-propelled speed of 3 MPH. The variable speed self-propelled mower offers speeds between 0 and 4 MPH, and the active speed management paddles allow you to easily adjust your walking pace during operation for increased control. The M18 FUEL™ mower features a steel cutting deck, a 3-in-1 grass management system, single-point height adjustment, a high-lift mode, front and side LED lights, vertical storage, and two deck handles. The M18 FUEL™ 21" Dual Battery Self-Propelled Mower is part of the M18™ system, fully compatible with over 200 solutions.
