How do i Change the oil for a cub cadet s 621 ss?

Answer 1

look around the base or the motor, there should be a small pipe with a cap on it sticking out from the motor, that's the drain,

remove the dipstick to allow air to flow in while draining oil, when oil stops flowing out drain, replace the cap, add oil, checking to make shure you Dont over fill it,

I couldn't find the drain plug and called the dealer. He said to drain the oil out of the dip-stick hole. Make sure when you turn the mower over to drain, that the carb is higher than the dip-stick hole, so that no oil will end up in the carb or filter.
