Abstract

The power head assembly for a cordless electric lawnmower has a removable upper housing that includes two spaced batteries, and a lower housing that is mounted to the deck of the grass cutting device. The upper housing has a handle, and at least one quick disconnect terminal that engages a mating quick disconnect terminal affixed to the lower housing. The lower housing includes an electric motor that is disposed between the two batteries when the upper housing is in place. A portion of the electric motor is located below the deck to further reduce the overall height of the device. The lower housing is mounted to the deck by several bolts which are placed in the same mounting pattern used to mount gasoline engines to a deck, so that the same decks may be used for both the cordless electric and gasoline-powered lawnmowers.
