Black and decker battery operated weed eater

The Automatic Feed Spool (AFS) is the technologically advanced line feed system found on Black & Decker string trimmer products. Using centrifugal force, the system monitors the amount of line being used and feeds more line automatically as the cutting line shortens.

Designed for use with Black & Decker auto feed string trimmers, the 30-foot factory-wound replacement spool features a . 065-inch diameter line utilizes centrifugal force to automatically feed the cutting string while eliminating bumps and hitches.
