Troy-Bilt GW-2178  Wheel Speed Lever with Knob

Levers can have many functions within your outdoor power equipment, often to aid the user for control and adjustments of their equipment, such as the height adjustment lever or engage lever on a walk-behind mower. Mechanical levers within the machine, such as a governor lever, will adjust other components. Excessive stress can damage levers. Damaged levers in your machine can impair control of the equipment, and should be replaced for optimal performance and safe operation.
