Problem 3: Uneven Cutting


When you’re mowing your lawn with your John Deere X394, you may notice that the grass is being cut unevenly. This can result in patches or streaks of uncut grass, making your lawn look untidy.

Dull blades can also contribute to uneven cutting, as they may tear the grass instead of cleanly cutting it. Additionally, mower deck misalignment can lead to uneven cutting, as it can cause one side of the deck to sit lower than the other.

Troubleshooting Tips

To address this issue, start by checking the tire pressure on your lawn tractor. Make sure that the tires are properly inflated according to the manufacturer’s recommendations. Next, inspect the blades on your mower deck. If they are dull or damaged, they will need to be sharpened or replaced. Finally, adjust the height of your mower deck to ensure that it is level from side to side. By following these troubleshooting tips, you can achieve a more even cut with your John Deere X394 and keep your lawn looking its best.
