  William AllenAug 16, 2025
  Several factors can prevent your Challenge Xtreme Lawn Mower from starting. It could be due to the engine being under load, so try raising the height of cut. Other possible causes include fuel starvation (fill the fuel tank), a cold engine (set the throttle to ‘choke’ position), incorrect or contaminated fuel (drain and refill with the correct fuel), a disconnected spark plug lead (connect it), or a faulty spark plug (clean and adjust the gap, or replace it).

Why is my Challenge Xtreme Lawn Mower not collecting grass well?
- D
  David SnowAug 28, 2025
  If your Challenge Xtreme Lawn Mower isn't collecting grass effectively, several factors could be responsible. Check if the airflow through the grass bag is restricted and clean the bag if necessary. Also, ensure the discharge chute isn't blocked and remove any blockages. Wet grass can also cause poor collection, so mow when the grass is dry. Make sure the grass bag isn't full and empty it if it is. Finally, check that the engine speed isn't too slow and set the throttle to the fast position.

  The discharge chute on your Challenge Xtreme Lawn Mower can block for several reasons: The grass may be wet, so mow dry grass instead. The cut height might be too low, so increase it. The grass bag could be full, so empty it. The airflow through the grass bag may be restricted, so clean the bag. The engine speed might be too slow, so ensure that the engine runs with optimal speed.

  Excessive vibration in your Challenge Xtreme Lawn Mower could stem from several issues: loose mounting bolts (tighten them), a loose blade bolt (tighten it), or a blade that's out of balance (balance the blade). If these steps don't resolve the vibration, the crankshaft might be bent, so consult your dealer.
