Before you start to change your lawn mower's oil, it's important to know there are two primary methods for draining oil: the siphon/pump method and the tilt method.
All of these instructions on performing a mower oil change applies to self-propelled and push mowers alike. Depending on your model, the instructions in this video may vary slightly.
Both methods work best if the engine and oil are warm. Make sure the mower is on a flat, level surface. It's not a bad idea to put down some newspaper or other material to catch any oil that may spill.
Remove the spark plug wire from the spark plug and keep it away from the spark plug to prevent unintended starting.
Clean the oil fill area of any debris.
Remove the dipstick.
Siphon method: Using the Arnold Siphon Pump, siphon the warm oil out of the dipstick fill tube. Insert the pump/siphon tube into the dipstick tube until it reaches the bottom of the dipstick fill tube. Insert the pump/siphon tube into the dipstick tube until it reaches the bottom of the oil container.
Tilt method: Place an appropriate catch container under the dipstick tube. Also make sure that this is opposite the air cleaner so that oil doesn't contaminate the air filter.
Siphon method: Manually siphon out the oil. Be careful as the oil may be hot and could cause burns if it is too warm. Tilt the unit towards the side the dipstick tube is located to remove as much oil as possible.
Tilt method: Carefully tip the mower in the direction of each catch container. Keep tilting the mower, making sure the oil is going into the catch container. Hold in this position until the oil flow slows to just a drip. Make sure the mower is tilted air cleaner side up to prevent oil contaminating the air filter.
Carefully tilt the mower back in the opposite direction to rest on the wheels. Remove the siphon tube if you were using that method.
Wipe up any spilled oil on the mower or floor if needed.
Refer to your Operator's Manual or Engine Owner's Manual for the type and amount of oil needed to refill. Fill the mower with the specified amount and grade of oil.
Note: Do not overfill as it can be as harmful to an engine as under filling.
Wait 1 to 2 minutes for the oil to settle into the unit and then follow the instructions in the equipment or engine manual for checking the oil level.
Replace and tighten the dipstick.
Reconnect the spark plug wire and you're done.
