  If your Troy-Bilt Lawn Mower engine won't start, make sure the blade control is engaged. Check that the spark plug boot is connected. If the fuel tank is empty or the fuel is stale, fill it with clean, fresh gasoline. If equipped with a primer, prime the engine as instructed. Inspect the spark plug; clean, adjust the gap, or replace it if necessary. Also, ensure the fuel line is not blocked and, if the engine is flooded, wait a few minutes before restarting without priming. If your mower has a fuel valve, ensure it's open, and if equipped with a choke, use it to choke the engine. Finally, for electric start models, check and replace the fuse if it's burnt.

  If your Troy-Bilt Lawn Mower engine runs erratically, start by checking the spark plug boot and ensure it's connected and tight. Clean the fuel line and fill the tank with fresh gasoline if it's blocked or the fuel is stale. Also, clear the vent in the gas cap and drain the fuel tank to refill with fresh fuel if there's water or dirt in the system. If your unit is running with the choke applied, push the choke knob in.

What to do if Troy-Bilt Lawn Mower will not mulch grass?
- W
  Wanda JohnsonAug 21, 2025
  If your Troy-Bilt Lawn Mower is not mulching grass effectively, it could be due to several reasons. Avoid mowing when the grass is wet, as this reduces mulching efficiency. If the grass is excessively high, mow once at a higher setting and then again at your desired height, or narrow the cutting path. A dull blade will also hinder mulching, so sharpen or replace it to improve performance.
