'G-MAX 40V' 2-in-1 Electric Lawn Mower - 20 Inch Manual


GreenWorks has multiple lines of all electric corded and cordless lawn tools. With a mission to bring yard care in into the 21st century, their products eliminate the smell, noise, hassle, and wasted energy associated with conventional, gas powered yard tools. Constantly updating their designs, GreenWorks has recently released a new 80V tool line to bring professional level power to the electric mower market.

Energy Efficiency Icon

GreenWorks tools use much less energy and 95 - 98% less carbon than gas powered tools (depending on the exact model and the local electricity grid.) While this might sound impossible, the truth is that small gas engines are incredibly inefficient. For example, most push mowers need about a gallon of gas to operate for an hour, while that same gallon could propel an entire car for more than 21 miles! The average gas mower uses 1 gallon of gas an hour and produces nearly 20 lbs of CO2-eqv greenhouse gases. These electric yard tools will use about 1.0 kWh of electricity per hour and release only 1.2 lbs of CO2-eqv, depending on what types of fuels power the regional grid. Electric yard and lawn equipment could save most people 380 lbs of CO2-eqv a year, or 2% of the average personal carbon footprint.

Green Savings Icon

Along with these big energy savings come some great financial benefits, too. For example, running a gas powered mower will use about a gallon of gas (which is at $2.50 now) and an electric mower will use about 0.5 kWh, which at the US average price of $0.11 / kWh, is about $0.06. For people who mow their yard about 20 times a year, they should save about $50 annually! Most GreenWorks products have an ROI of 3-6 years, depending on the exact model and the local prices of gas and electricity.
