Why Hayter Harrier 41 410D engine will not start?

  amber66Aug 16, 2025
  There are several reasons why your Hayter Lawn Mower engine might not start. First, ensure the engine isn't under load by raising the height of cut. Next, check if the fuel tank is empty and fill it if necessary. If the engine is cold, set the throttle to the ‘choke’ position. Also, verify you're using the correct, uncontaminated fuel; if not, drain the tank and refill. Make sure the spark plug lead is connected and the throttle is set to the ‘fast’ position. Ensure the engine brake is released. A faulty spark plug could also be the culprit, so clean, adjust the gap, or replace it. If you have a model 412, check and charge the battery. Finally, inspect the wiring for any faults.

  If the discharge chute of your Hayter Lawn Mower blocks, it could be due to several reasons. If the grass is wet, mow only when it's dry. If the cut height is too low, increase it. Another reason may be that the grass bag is full, so empty it. Check if the airflow through the grass bag is restricted and clean it if necessary. Lastly, if the engine speed is too slow, set the throttle to the fast position.
