  • Patent number: 9270152
    Abstract: An electric auger including an auger assembly with a coupling assembly at a proximal end, a cutting assembly having at least one cutting blade located at a distal end, and a helical flight located between the proximal end and the distal end. The electric power head includes an A/C motor with a drive shaft configured to mechanically couple with the proximal end of the auger assembly. An on-board 36-volt DC battery pack powers the A/C motor. A controller includes an inverter that converts DC power to A/C power for the A/C motor. The ratio of cubic inches of ice cut per battery ampere-hour per weight in pounds of the electric auger is at least about 900 (inches3/ampere-hour/pounds).
