  If your Troy-Bilt Lawn Mower isn't mulching grass effectively: - Ensure the engine speed is not too low by placing the throttle in the FAST (rabbit) position. - Avoid mulching when the grass is wet. - If the grass is excessively high, mow once at a high cutting height, then mow again at the desired height, or make a narrower cutting swath. - Check for a dull blade; sharpen or replace it as needed.
