Abstract
A combination blower assembly and string trimmer whereby the string trimmer head is easily detachable without the use of any tools. The device includes a blower assembly that further includes an upper and lower housing mated together to form a volute-shaped cavity where an impeller with airfoil-shaped blades reside. The detachable string trimmer head is located under the lower housing of the blower assembly and is easily attached or removed from the blower assembly by a simple push and turn motion. The blower assembly further includes an air inlet and air inlet cover. When the air inlet cover is rotated to a position where the air inlet is open the blower assembly is operable and the string trimmer is inoperable. Furthermore, when the air inlet cover is rotated to a position where the air inlet is closed the blower assembly is inoperable and the string trimmer is operable.
