The Greenworks 40V 21-inch self-propelled mower is a cordless walk-behind with a brushless motor, rear-wheel drive and a steel deck. It runs on two 40V batteries through dual active ports, so it keeps cutting when one pack drains, and it offers bagging, mulching and side discharge with a single-point height lever. It suits owners of yards up to about a third of an acre who want gas-like traction without fuel or pull cords. Against gas mowers it is quieter and starts with a button, but it is heavy at about 84 lbs and runtime depends on grass conditions and battery age.
