Cub Cadet typically places the model number on a label on the main housing near the engine, though some string trimmers have it on a label along the shaft. Check the housing and shaft carefully for a combination of letters and numbers, and distinguish the model number from the serial number. Type it into our model number lookup and the catalog narrows to parts made for your unit. Using the complete model number filters the full Cub Cadet string trimmer parts selection, not just one part, so you can match every associated part to the correct equipment. That means fewer wrong orders and a faster repair.
