turn your mower over and look at the bottom deck. you should see a 1/2 inch square recessed. use a 1/2 inch rachet and take that plug out. turn the mower back over and the oil will fall out onto the floor, or dirt so you should have something under it to catch the oil. when it has drain out completely put the plug back in and add oil. simple as that!
