Uneven mowing

Uneven mowing results — Inconsistent grass height or missed areas

husqvarna · Automower 430xh/450xh

What does Uneven mowing mean?

The lawn does not have a consistent, even cut, showing patches of longer grass or areas that appear to be missed by the product.

Common Causes

  • The product works too few hours per day.
  • The work area's shape requires the 'Lawn coverage' function.
  • The 'How often?' setting is incorrect for the work area layout.
  • The work area is too large for the current schedule.
  • Dull blades.
  • Long grass in relation to the set cutting height.
  • Accumulation of grass by the blade disc or around the motor shaft.

Repair Steps & Checklist

Click steps to track your progress.

  1. 1

    Increase the daily mowing time in the schedule settings to allow for more coverage.

  2. 2

    If the work area has remote sections, use the 'Lawn coverage' function to steer the product to those areas.

  3. 3

    Check and adjust the 'How often?' setting to match the work area's layout for optimal coverage.

  4. 4

    Replace all dull blades to ensure efficient and even cutting.

  5. 5

    Increase the cutting height initially for long grass, then gradually lower it one step at a time every second week.

  6. 6

    Check that the blade disc rotates freely; screw it off and remove any accumulated grass or foreign objects if needed.
