Mower leaves uncut strips of grass and shows uneven cutting height across the lawn.

Safety first: Turn OFF the main power, disconnect the battery, and wear gloves before handling blades.

• Inspect blades: Remove the blades or blade disc and check for dull edges, chips, or bends. Replace blades if they are not sharp and straight.
• Check cutting height setting: Verify that the height adjustment mechanism is set evenly and not jammed on one side.
• Examine blade disc: Spin the disc and look for wobble. A bent disc will cause uneven cutting and should be replaced.
• Check shaft play: Gently move the blade disc up/down and side‑to‑side. Excessive movement indicates worn motor bearings.
