Briggs & Stratton 39496 Height Adjustment Knob Kit

The Briggs & Stratton 39496 Height Adjustment Knob Kit operates by engaging a threaded or locking interface that allows controlled raising and lowering of equipment components through manual rotation. It operates by translating rotational movement into linear adjustment along a height control shaft, securing the selected position through internal threading and friction-based connection within the adjustment mechanism. It is placed on lawn mower or outdoor power equipment height adjustment assemblies where it attaches to the control linkage to set and lock cutting deck or handle height positions within the equipment frame.
