Greenworks Commercial - 82V 21" Brushless Push Mower - 5Ah Battery + Dual-Port Charger - Greenworks 82V Platform [82LM21-5DP]

The Greenworks Commercial 82LM21-5DP is an 82V, 21-inch brushless direct-drive push mower designed for professional grounds maintenance and demanding residential mowing. Its stamped 14-gauge steel deck, dual battery ports, SmartCut Technology, and 3-in-1 cutting capability provide a durable and adaptable solution for mulching, bagging, or side discharging grass clippings. This complete kit includes one 82V 5.0Ah / 400Wh lithium-ion battery and an 8A dual-port rapid charger, making it a practical choice for maintaining lawns, commercial properties, landscaped areas, and other turf where quiet, battery-powered operation is preferred.

Professional 82V Mowing Performance

The brushless direct-drive cutting motor has a 2.5kW maximum power rating and operates with a blade speed of 2,800–3,200 rpm. SmartCut Technology supports efficient cutting performance through the 21-inch deck and dual cutting motors, while the claimed blade-tip speed reaches 17,000 feet per minute. The push-drive design gives the operator direct control while mowing, without the added complexity of a self-propelled drive system.

The mower's dual battery ports automatically switch between batteries, helping extend working time when two compatible batteries are installed. One 5.0Ah battery is supplied with this kit. The manufacturer states a runtime of up to 1.5 acres or 90 minutes when using two 8.0Ah batteries; actual runtime varies with grass conditions, cutting height, operating technique, and battery configuration.

Flexible 3-in-1 Cutting

Choose the cutting method that best suits the lawn and conditions. The 82LM21-5DP supports mulching, rear bagging, and side discharge, allowing clippings to be finely redistributed, collected, or discharged from the side of the deck. A single-lever, seven-position height adjustment provides cutting heights from 1-3/8 inches to 4 inches for adapting to different turf requirements.

Durable, Convenient Design

The 21-inch stamped 14-gauge steel deck is built for regular use, while the front 8-inch and rear 10-inch wheels support maneuverability across maintained lawn areas. Push-button starting eliminates the need for fuel or engine pull-starting. An adjustable handlebar folds for vertical storage, helping reduce the mower's storage footprint. The mower also includes an automatic shut-off safety feature and has an IPX5 ingress protection rating. With a stated operating noise claim of 60 dB, it is suited to applications where reduced operating noise is beneficial.
