  If your Troy-Bilt Lawn Mower engine won't start, several factors could be the cause. Ensure the blade control handle is engaged. Check that the spark plug wire is connected. The fuel tank may be empty or contain stale fuel, so refill with fresh gasoline. A blocked fuel line could also be the culprit, so try cleaning it. The spark plug might be faulty, requiring cleaning, gap adjustment, or replacement. Lastly, if the engine is flooded, wait a few minutes before attempting to restart, and avoid priming it.

Why Troy-Bilt 566 Lawn Mower will not mulch grass?
- D
  David JohnstonSep 1, 2025
  If your Troy-Bilt Lawn Mower won't mulch grass effectively, it may be because the grass is wet, so wait until the grass is dry to cut. If the grass is excessively high, mow once at a high cutting height, then mow again at the desired height. A dull blade can also prevent mulching, so sharpen or replace the blade.
