Troy-Bilt typically places the model number on a label attached to the trimmer's main housing near the engine or fuel tank. Check the plastic body carefully, and look for a label or stamped number rather than confusing it with the engine serial number. Once you have the model number, enter it in the search bar to filter the catalog to parts that fit your complete Troy-Bilt string trimmer. This narrows the selection across every associated part category, not just engine parts or piston ring sets. Use the full model number, including letters and numbers, so the results match your equipment accurately. That means fewer wrong orders and a faster repair.
