ABSTRACT:
A cordless twin blade electric lawnmower having substantially improved performance and efficiency is disclosed. The lawnmower includes a pair of spaced counter-rotating cutting blades, a pair of motors driving each of the respective blades and a battery for energizing the motor under the control of a switch. The housing of the lawnmower is supported on wheels and provides a passageway comprising a helical convolute for each of the respective blades. The two convolutes join in the center of the mower and provide a continuing passageway into a rear mounted bag. The front of the bag is partially closed by a chute which, when the bag is not present, automatically falls into a guard position wherein all air flow, objects and grass are directed downwardly at the rear of the motor. The guard also provides, in this position, for distribution of the grass across the width of the mower span.
