The Greenworks 12" Commercial Top-Handle Chainsaw is the most powerful battery-powered chainsaw in its class. This unit's combination of power and speed sets the standard for lithium-ion battery power and outperforms gas. With the equivalent power of a 1.9 HP and 31cc displacement gas engine, this ultra high-performance chainsaw leverages a built-in commercial-grade Brushless Direct Drive Motor and lithium-ion batteries to provide the power and torque necessary to cut faster than gas-all at only 9 lbs. operating weight.
