Why won't my Cub Cadet Lawn Mower engine start?
- C
  Chris BowersAug 12, 2025
  If your Cub Cadet Lawn Mower engine fails to start, several issues could be the cause. First, ensure the PTO/Blade Engage knob is in the disengaged (OFF) position and that the parking brake is engaged. Check that the spark plug wires are connected and the throttle lever is in the FAST position. If it still doesn't start, make sure the choke is activated. The fuel tank may be empty or contain stale fuel; if so, fill it with fresh gas. A blocked fuel line or faulty spark plugs could also be the problem; clean the fuel line, replace the fuel filter, or clean/replace the spark plugs. If the engine is flooded, crank it with the throttle in the FAST position. Finally, check for blown fuses and replace them if necessary.

Why is my Cub Cadet 13WQ91AP009 Lawn Mower engine running erratic?

  Christopher WeberAug 16, 2025
  If your Cub Cadet Lawn Mower engine is running erratically, there are several things you can check. First, ensure the choke is off. Next, check the spark plug wires to make sure they are properly connected. A blocked fuel line or stale fuel could also be the issue; clean the fuel line, fill the tank with fresh gasoline, and replace the fuel filter. Also, check the vent in the gas cap to ensure it isn't plugged. Water or dirt in the fuel system can cause this problem, so drain the fuel tank and refill it with clean, fresh gasoline. Lastly, a dirty air cleaner can cause erratic running; replace the air cleaner paper element or clean the foam precleaner.

  If your Cub Cadet Lawn Mower is providing an uneven cut, the deck may not be leveled properly, so perform a side-to-side deck adjustment. A dull blade can also cause this; sharpen or replace the blade. Finally, check the tire pressure in all four tires to ensure it's even.

What to do if my Cub Cadet 13WQ91AP009 Lawn Mower will not mulch grass?

  Jennifer CowanAug 25, 2025
  If your Cub Cadet Lawn Mower is not mulching grass effectively, make sure the engine speed is set to FAST. Avoid mulching when the grass is wet. If the grass is excessively high, mow once at a higher cutting height before mowing again at the desired height, or reduce the cutting swath. Finally, ensure the blade is sharp; sharpen or replace it if it's dull.

Why does my Cub Cadet 13WQ91AP009 engine idle rough?

  Robert LeeSep 4, 2025
  If your Cub Cadet Lawn Mower engine idles roughly, the spark plugs may be fouled, faulty, or have a gap that is too wide. Replace the spark plugs and set the correct gap. A dirty air cleaner can also cause this issue; replace the air cleaner element and/or clean the pre-cleaner.
