The Greenworks 60V 21” Self-Propelled Walk-Behind Lawn Mower stakes its claim as the rightful lawn titan. The muscle of this mower flexes with its heavy-duty 21-inch stamped steel deck. Better, more intelligent power than any of its gas competition , the 21-inch cut delivers superior cut quality with premium blade speed and RPMs ranging between 2800-3200. The mower features multiple blades to ensure the best cut quality while increasing the performance of mulching and bagging. Runtime is a sure thing with the included (2) 5.0 Ah batteries and dual-ports with one active port and one port for storage, longer runtime with two batteries. With 80 minutes of runtime and a powerfully tough 21-inch steel deck this mower comes to play with the best. The mower is equipped with high-intensity LED headlights that provide visibility for early mornings or late nights. The turbo button provides excellent lift for leaf-pickup and takes the mower to maximum power.  Fully charge the included batteries in 100-minutes. Designed to be quiet at only 84 dB, mow where the gas guys can’t, also forget the gas can, oil, spark-plug, fuel-filter, and air filter.  This mower will not only give you a premium performance but will also have a five-year cost savings of $619 compared to using a 21” gas-powered walk-behind mower. Includes (2) 5.0 Ah lithium-ion battery, rapid charger. Battery is compatible with 75+ Greenworks Pro 60V products.
