Abstract

A trimmer head assembly for a trimming machine. The trimmer head assembly includes a spool. The spool has a central tubular hub. The spool also has a central flange that radially extends from the hub. A trim line conduit is joined to the central flange. The trim line conduit has a first open end. The first open end leads to a first straight section. The first straight section leads to a curved central section. The curved central section leads to a second straight section. The second straight section leads to a second open end. The curved central section passes around the center of the spool. A housing is provided that receives the spool therein. When loading trimmer line into the trimmer head assembly, the shape of the conduit enables the trimmer line to pass around the central opening in the spool without binding.
