Place the oil waste pan under the plug. Remove the plug. Allow all the oil to drain. Replace the plug. Remove and replace the oil filter. It will be located on the engine block.
Pour new oil in to the engine, one quart at a time. Use the specified oil for the tractor, according to the owner's manual. Check the oil level on the dipstick. Add oil in small amounts when topping up.
Locate the fuel line underneath the tractor. Attached to the line will be the fuel filter. Remove and replace the filter. It is attached on both ends.
Check the tires' air pressure. If they are low, fill them to the proper levels.
