Husqvarna Automower 450XH Robotic Lawn Mower CUTTING MOTOR OVERLOAD Error Fix: Cutting Motor Drawing Too Much Current

The blade disc motor is overloaded — the most common cause is very tall or thick grass that exceeds the mower cutting capacity; a stick, stone, or other debris jammed in the blade disc also triggers this; retrieve the mower, flip it over carefully (turn off and remove blades first), and clear any jammed debris; if the grass has grown too tall between mowing sessions, reduce the maximum cutting height temporarily and increase mowing frequency; dull or damaged blades increase motor load — inspect and replace blades regularly (the Automower uses small pivoting razor blades that are inexpensive and easy to swap)
