Mower leaves clumps of grass and the cut looks ragged, with brown tips on blades of grass.

Safety first: Press STOP, switch OFF, and remove the key before touching blades.

• Replace blades: Install a full set of new original Gardena blades and screws.
• Raise cutting height: Set the mower to a higher cutting level and gradually lower over several days.
• Mow more often: Increase the daily mowing schedule so the mower cuts small amounts frequently.
• Avoid wet mowing: If possible, schedule mowing for dry periods to prevent clumping and sticking.

Sharp blades and proper height will usually restore a clean, even cut within a few days.
