  • Inadequate Overlap: Inefficient overlap during mowing passes can leave streaks of uncut grass.

Troubleshooting the Mowing Deck

To resolve uneven cutting issues:

  1. Inspect Blades: Check the mower blades for wear and tear. Sharpen or replace them if necessary. Ensure both blades are equally sharp.
  2. Level the Deck: Balance the mowing deck by adjusting its height on each side. Refer to your owner’s manual for instructions on how to do this correctly.
  3. Check Tire Pressure: Verify that the tires are adequately inflated to the recommended pressure levels. This ensures even weight distribution across the mower.
  4. Clear Obstacles: Before mowing, clear the area of any debris or obstacles that may hinder the mower’s path.
  5. Optimal Speed: Mow at a moderate speed that allows the blades to cut the grass evenly. Avoid rushing through the process.
  6. Overlap Effectively: Ensure there is sufficient overlap between each mowing pass to prevent streaks of uncut grass.

Regular Maintenance for a Level Cut

To maintain a level cut over the long term, consider these preventive measures:

  • Scheduled Blade Maintenance: Regularly inspect and sharpen or replace the mower blades as needed.
  • Deck Balancing: Periodically check and adjust the mowing deck’s balance to ensure even cutting.
  • Tire Maintenance: Maintain the recommended tire pressure and inspect for any damage or wear.
