Robot mower leaves patches of uncut grass and blades seem to tear rather than cut cleanly

Safety: Turn OFF the mower, remove battery if specified, and wear cut-resistant gloves.

• Inspect blades: Flip the mower and examine each pivoting blade on the disc. Look for nicks, bends, or rust.
• Check pivoting: Ensure each blade swings freely on its screw. Stuck blades reduce cutting quality.
• Replace blades: Remove old blades and screws. Install new genuine Makita robot mower blades with new screws, tightening to the torque specified in the manual.
• Balance check: Confirm all blade positions are filled and blades are of equal type to avoid imbalance.

Regularly replacing blades (often every 1–2 months in heavy use) maintains cut quality and reduces strain on the cutting motor.
