Many ped mowers do not have a drain plug, dealers will suck the oil out throuht the dipstick hole, you can buy simple vacume pumps to do it this way yourself,otherwise you will have to turn the engine, to re fill it goes into the dip stick hole, do not over fill.Briggs engines take an SAE 30 oil, Honda and Kawasaki egines tend to take a SAE 1030
