Why is my Troy-Bilt B809H Lawn Mower engine overheating?

  Stephanie GonzalezAug 21, 2025
  If your Troy-Bilt Lawn Mower engine overheats, it could be due to low engine oil level. Fill the crankcase with the proper capacity and weight of oil. Another possible cause is restricted airflow. Clean grass clippings and debris from around the engine’s cooling fins and blower housing.

Why Troy-Bilt B809H will not mulch grass?
- J
  Joseph WeberAug 25, 2025
  If your Troy-Bilt Lawn Mower is not mulching grass effectively, ensure the engine speed is set high by placing the throttle in the FAST (rabbit) position. Avoid mowing when the grass is wet; wait until it's dry. 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. Also, sharpen or replace the blade.
