  If your BigDog Lawn Mower engine won't start, starts with difficulty, or fails to keep running, several factors could be at play. First, ensure you have enough fuel and that the fuel line isn't blocked. If the fuel valve is off, turn it on. Also, check for incorrect fuel type and replace it if necessary. A dirty fuel filter could also be the culprit, so replace it. Finally, make sure the choke is engaged.

  Edward WongAug 22, 2025
  If your BigDog Lawn Mower experiences a loss of power or won't operate in either direction, several factors could be responsible. Start by servicing the air cleaner if there are restrictions. Check the hydraulic oil level in the reservoir and add oil if it's insufficient. Ensure the tow valve is closed. If the traction drive belt is worn, loose, or broken, install a new one. Also, check the filter and fittings for air in the system. Adjust the steering linkage, if needed.
