  If your Craftsman Lawn Mower engine won't start, make sure the blade control is engaged. Also, check if the spark plug boot is connected and that the fuel tank isn't empty or filled with stale fuel. If your lawn mower is equipped with a primer, make sure to prime the engine as instructed. A faulty spark plug could also be the culprit, so clean, adjust the gap, or replace it. If the engine is flooded, wait a few minutes before attempting to restart. For a blocked fuel line, contact your Parts & Repair Center to have it cleaned.

  If your Craftsman Lawn Mower with electric starter fails to start, ensure the Electric Starter Push Key is fully inserted until it snaps into place. Check if the battery is charged, referring to the Battery Charger Instructional Manual for charging instructions. If the circuit breaker tripped, stop the engine, remove the Electric Starter Push Key, and disconnect the spark plug boot. Clear any debris blocking the blade, reattach the spark plug boot and reinsert the key. Wait one minute for the circuit breaker to reset before reattempting to start.

  If your Craftsman Lawn Mower will not self-propel, check the belt for proper pulley installation and movement. Stop the engine, disconnect the spark plug boot, and clean out any debris. Inspect the belt for damage or wear, and contact your Parts & Repair Center to have the belt replaced, if necessary.

  If your Craftsman Lawn Mower engine runs erratically, ensure the spark plug boot is securely connected and tightened. Replace stale fuel with clean, fresh gasoline. Check the gas cap vent and clear any blockages. If there's water or dirt in the fuel system, run the engine until it stops due to lack of fuel, then refill with fresh fuel. For a blocked fuel line, contact your Parts & Repair Center to have it cleaned.

What to do if my Craftsman M235 Lawn Mower will not mulch grass?

  bankssydneySep 4, 2025
  If your Craftsman Lawn Mower won't mulch grass, avoid mowing when the grass is wet; wait until it's dry. If the grass is excessively high, mow once at a high cutting height, then mow again at the desired height, or make a narrower cutting path. Also, ensure the blade is sharp; sharpen or replace it if it's dull.
