Husqvarna 574039301  Knob, 5/16-18 X 1/2

A Knob can refer to a handle, grip, button, or protrusion. The handles on starter coils, hitches for attachments, or user input adjustment mechanisms, as examples, all can commonly be referred to as knobs. Some knobs help hold commonly replaced parts of your model in place, and may need to be replaced if lost or damaged for optimal use. We always suggest purchasing replacement knobs from a genuine OEM original parts dealer, like us, to ensure they fit exactly as intended for safe operation by the OEM.
