HART 318423001 Bump Feed Trimmer Head Assembly for HART 40V Cordless String Trimmers
MPN 318423001
Overview
The HART 318423001 is the genuine replacement bump feed trimmer head assembly for HART 40V cordless string trimmers. It replaces the complete head on the trimmer, not just the line spool, so it is the right part when the housing, cap or bump knob is cracked, worn or no longer feeds line. Dealer catalogs list it for the HART HLST04LBVNM, and replacement-part listings tie the same number to other HART 40V trimmers (see Fits).
