    It is important to drain the oil from the gearbox and the crankcase. This can be done in a similar fashion to draining out the fuel. As lawn mower oil is a hazardous waste, it is very important that you dispose of it properly (such as a waste dumping station) and never pour it into the sewer or on the ground.
