Changing the engine oil is just a small part in the overall maintenance of your Cub Cadet tractor. You should change the engine oil regularly and often. The manufacturers of Cub Cadet tractors recommend you change the oil and oil filter after every 50 working hours. The first oil change should be completed after the first 5 to 10 working hours—after the engine has been broken in. It is fine if you would like to change the oil more often than is recommended, but do not go longer than 50 hours between oil changes.
Start the engine, and allow the engine to warm up for a few minutes. Warm oil runs out of the crank case easier than cold oil. Warm oil will also take away some of the sediment that may build up on the bottom of the crank case as it leaves the crank case.
Open the engine hood, and find the oil drain port on the right side of the engine. If you are facing the tractor, the oil port will be on your left. Remove the protective drain cap, and slide the oil drain hose over the drain port.
Open the oil fill cap. Either pull the oil port open or twist it open depending on how your tractor is equipped. Allow the used oil to drain into an approved used oil can. At least 2-1/2 quarts of oil will drain from the crank case, so be sure the oil collection can will accommodate that amount of oil.
Close the drain port when the crank case has been emptied of oil. Twist the oil filter off of its engine mount, and place it port-side down over the used oil container to allow oil to drain out. Twist a new oil filter onto the oil filter port so it is hand tight.
Refill the crank case with the recommended engine oil type for your area. The typical engine oil used is 10W30 engine oil, but you can also use SAE30 weight oil in some areas. Add 2-1/2 qts. of oil before using the dipstick to check the remaining amount of oil needed to fill the crank case. Top the oil off as needed.
Wipe any excess oil off of the drain port, the oil filter and the oil fill port with a cloth rag.
Take the used engine oil and the oil filter to a local recycling center for recycling.
