Troy-bilt 731-09582-a-49 Bump Knob

Product Description

The TROY-BILT 731-09582-a-49 is a bump feed knob designed for use on compatible TROY-BILT string trimmer heads. This component serves as the advance mechanism for the trimmer line, allowing the operator to tap the head against the ground to feed additional line during operation. The red color indicates OEM identification for this specific head assembly. Replacement of a worn or damaged bump knob restores proper line-feed function and keeps the trimmer head operating as intended. This is a direct OEM-sourced replacement part installed by lawn and garden equipment technicians.

This bump knob is used in residential string trimmer applications on TROY-BILT equipment. It is a common wear item that cracks or breaks under repeated contact with hard surfaces during normal trimmer operation. Replacing a failed bump knob is a routine service task performed during seasonal maintenance or as needed when line will no longer advance through the trimmer head.
