  If the motor of your LawnMaster Lawn Mower stops, it could be due to a foreign object blocking the mower. Remove the object to resolve this. Alternatively, the motor protection may have engaged because of overheating. If this is the case, allow the mower to cool down. When mowing, cut long grass in stages and avoid overloading the motor to prevent future occurrences.
