Display shows “Error 4 – No drive, Mower limited” or similar, mower moves only a short distance or not at all.

Safety first: Press STOP and switch the mower OFF before touching the wheels or underside.

• Inspect lawn conditions: If the grass is very tall or wet, set the cutting height to the highest position and mow in stages. Avoid operation in muddy or waterlogged areas.
• Clean wheel housings: Turn the mower on its side (battery side up as per manual). Remove packed grass, mud, and debris from around the drive wheels and chassis.
• Check wheel tread: Examine the rubber tread on the Gardena wheels. If it is worn smooth, the wheels may slip and cause overload. Replace worn wheels.
• Allow cooling time: If the mower has been working hard, let it rest on the charging station for 30–60 minutes to cool the drive motors.
• Test on a flat area: Place the mower on a flat, dry section of lawn and start a manual mowing session to see if the error reoccurs.

Persistent Error 4 on normal grass height may indicate failing drive motors or a control board issue, which should be diagnosed by a service center.
