Abstract: Trimmer heads for trimmers are provided. A trimmer head includes a drive plate defining a lug slot, and a locking lug, the locking lug movably positioned in the lug slot and movable between an unlocked position and a locked position. A trimmer head further includes a drive plate cover connectable to the drive plate such that the locking lug is disposed between the drive plate and the drive plate cover. A trimmer head farther includes at least one operational head, the at least one operational head connectable to the drive plate. The connected operational head is locked to the drive plate when the locking lug is in the locked position and the connected operational head is unlocked from the drive plate when the locking lug is in the unlocked position.

Abstract: A power tool and an accessory mount device are provided. The device includes a driven member, a plate, and a flyweight comprising a first flyweight portion configured to translate along the first direction and contact the plate. The flyweight includes a second flyweight portion configured to translate along the second direction. The flyweight is positioned at a hinge between the first flyweight portion and the second flyweight portion and is configured to rotate along the hinge to push the first flyweight portion to the plate and translate the plate and the driven member along the first direction toward the first end when a rotational speed threshold about the first axis is exceeded.
