Bump Head Knob Assembly Specifications

This OEM bump head knob assembly, known simply as the bump head assembly sometimes, advances the line on your trimmer in the spool. Black in color, it is made of plastic and steel and is sold individually. Tap your trimmer on the ground to see if the cutting line advances to determine if there is a problem with this part. If it will no longer feed, it is likely that this part needs to be replaced. Most of our customers rated this repair as easy. You can attach your new part to the cutting head with no special tools required to complete the repair.
