Abstract: A powered device includes a powerhead unit and an attachment unit selectively attachable to and powered by the powerhead unit. The powerhead unit includes a motor, a first shaft segment having a first driveshaft segment coupled to the motor, and a first connecting portion attached to the first shaft segment. The attachment unit includes an operational unit configured to be driven by the motor, a second shaft segment having a second driveshaft segment coupled to the operational unit, and a second connecting portion attached to the second shaft segment for coupling to the first connecting portion. One of the first connecting portion and the second connecting portion defines an axial opening having a keyway and includes a button having a hook portion. The other of the first connecting portion and the second connecting portion defines a slot and includes a key.

Abstract: An outdoor tool includes a powerhead unit and an attachment unit. The powerhead unit includes a motor, a housing assembly housing the motor and including a handle portion, and a first shaft segment supported within the housing assembly and extending along a shaft axis to a first connecting portion. The powerhead unit also includes a first driveshaft segment coupled to the motor and extending within the first shaft segment, a switch supported within the handle portion and operable to activate the motor, and a trigger assembly. The trigger assembly includes a trigger configured to selectively actuate the switch, a first lock-off member, and a second lock-off member. The attachment unit is selectively couplable to and powered by the powerhead unit.
The attachment unit includes an operational unit configured to be driven by the motor, a second shaft segment, and a second connecting portion.
