Greenworks Commercial - 82V 21" Brushless Self-Propelled Mower - 8Ah Battery + Dual-Port Charger - Greenworks 82V Platform [82LM21S-8DP]

The Greenworks Commercial 82LM21S-8DP is an 82V, 21-inch brushless self-propelled lawn mower kit designed for professional and demanding residential mowing applications. Its rear-wheel-drive system provides variable-speed propulsion up to 3.5 mph, while the 14-gauge stamped steel deck supports three mowing methods: mulching, rear bagging, and side discharge. The kit includes one 8.0Ah / 640Wh lithium-ion battery and an 8A dual-port rapid charger, providing a complete starting setup for the Greenworks Commercial 82V battery platform.

Professional 82V Mowing Performance

The 3 kW-class brushless direct-drive cutting system delivers up to 3.4 kW of peak power and maintains a constant blade-tip speed of 17,000 FPM. SmartCut technology automatically adjusts power for changing grass conditions, helping the mower maintain cutting performance as the workload varies. A 2,800–3,200 rpm blade speed range supports efficient cutting across a variety of lawn conditions.

The mower’s 21-inch cutting width is suited to maintaining lawns and larger landscaped areas, while the steel deck is built for regular use. Seven cutting-height positions can be selected with a single lever, with an adjustment range from 1-3/8 inches to 4 inches. This allows the cutting height to be matched to the lawn and mowing conditions without requiring separate wheel adjustments.
