Power head assembly for electric grass cutting device
First Claim
1. A power head assembly for a cordless electric grass cutting device, comprising:
- a first housing and a second housing;
an electric motor substantially enclosed by said first housing, said motor having a rotatable output shaft and a shaft centerline;
a first battery substantially enclosed by said second housing, said first battery being disposed on a first side of said motor when said second housing is adjacent to said first housing;
a second battery substantially enclosed by said second housing, said second battery being disposed on a second side of said motor when said second housing is adjacent to said first housing; and
quick disconnect terminal means for electrically connecting said first and second batteries in said second housing to said motor in said first housing without the use of a tool, and for electrically disconnecting said first and second batteries from said motor without the use of a tool.

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.
