  If your MTD Lawn Mower engine cranks but doesn't start, several factors could be at play. Make sure the throttle or choke is in the correct starting position by consulting your operator's manual. Check if the gasoline tank is empty and fill it if needed. Inspect the fuel line or in-line fuel filter for any blockages and clean them if necessary. Ensure the spark plug lead is securely connected. If the spark plug is faulty and doesn't fire at the electrode, replace it. If the air cleaner is dirty, refer to the engine manual packed with your unit for cleaning instructions.

  If your MTD Lawn Mower isn't discharging grass properly or leaves uncut strips, it could be due to a few reasons. Ensure the engine speed is set to full throttle. Try using a lower ground speed. If the cutting height is too low, raise the deck. Also, check if the blades are short or dull; sharpen or replace them as needed.

  If your MTD Lawn Mower engine won't crank, it could be due to several reasons. First, ensure the safety switch button is fully depressed by the actuator. Check that the battery is correctly installed with the negative terminal connected to the black ground wire. The battery might be dead or weak, so ensure it's fully charged before installation. Also, inspect the fuse or circuit breaker and replace it with an automotive type fuse if blown. Finally, check the engine ground wire to ensure it's properly connected from the engine to the frame or mounting bolt.

Why is my MTD Lawn Mower engine smoking?

  Laurie HarmonAug 17, 2025
  If your MTD Lawn Mower engine is smoking, it may be due to overfilling the engine oil; check the oil level. Another potential cause is the engine losing crankcase vacuum, which means the engine breather may be defective and needs replacement.
