Why is my Craftsman 247.203723 not mulching grass?
- P
  Paul Conner DDSSep 12, 2025
  If your Craftsman Lawn Mower isn't mulching grass properly, consider these potential causes: * The engine speed might be too low. Place the throttle in the FAST (rabbit) position. * The grass might be wet. Avoid mulching when the grass is wet. * The grass might be excessively high. Mow once at a high cutting height, then mow again at the desired height or make a narrower cutting swath. * The blade might be dull. Sharpen or replace the blade.

  Michele McclureAug 27, 2025
  If your Craftsman Lawn Mower is producing an uneven cut, you should first perform a side-to-side deck adjustment to ensure it is leveled correctly. Next, check the blade; sharpen or replace it if it's dull. Finally, verify that the tire pressure is consistent in all four tires.

What to do if Craftsman Lawn Mower engine runs erratically?

  angela83Aug 28, 2025
  If your Craftsman Lawn Mower engine is running erratically, it could be due to several reasons. First, check if the choke is activated and deactivate it. Next, ensure the spark plug wires are securely connected. A blocked fuel line or stale fuel could also be the culprit; in this case, replace the fuel line, fill the tank with clean, fresh gasoline, and replace the fuel filter. Additionally, check if the vent in the gas cap is plugged and clear it, or replace the cap if damaged. Water or dirt in the fuel system can also cause this issue, so drain the fuel tank and refill with clean, fresh gasoline. Lastly, a dirty air cleaner can lead to erratic engine performance, so replace the air cleaner paper element or clean the foam pre-cleaner if your mower is equipped with one.

Try replacing the spark plug and setting the correct gap. Another potential cause is a dirty air cleaner. In this case, replace the air cleaner element and/or clean the pre-cleaner.
