A well-maintained lawn mower is essential for keeping your lawn looking its best. One of the most important maintenance tasks for a riding lawn mower is changing the oil. Regular oil changes can help extend the life of your mower and ensure it runs smoothly. In this article, we will discuss how to change the oil in a riding lawn mower, including the tools you will need and the steps to follow.
Tools You Will Need
Before you begin, make sure you have the following tools on hand:
- A new oil filter
- A socket wrench
- A funnel
- A drain pan
- A rag or paper towels
- A new bottle of oil (check your mower’s manual for the recommended type and amount)
Steps to Follow
- Start by parking your riding lawn mower on a flat, level surface. Make sure the engine is cool before you begin.
- Locate the oil drain plug on the bottom of the engine. It is usually a bolt with a square or hexagonal head.
- Place the drain pan under the oil drain plug to catch the old oil.
- Using the socket wrench, loosen the drain plug and remove it completely. Allow the old oil to drain completely into the pan.
- While the oil is draining, locate the oil filter on the side of the engine. Use the socket wrench to remove it and discard it.
- Use a rag or paper towels to clean any excess oil around the oil filter area.
- Take your new oil filter and apply a thin layer of oil around the rubber gasket. This will help create a tight seal.
- Install the new oil filter by hand, making sure it is snug but not too tight.
- Once the old oil has finished draining, replace the drain plug and tighten it with the socket wrench.
- Using the funnel, pour the new oil into the oil fill tube. Check your mower’s manual for the recommended amount of oil.
- After adding the oil, start the engine and let it run for a few minutes. This will help distribute the new oil throughout the engine.
- Turn off the engine and check the oil level using the dipstick. Add more oil if necessary.
- Wipe any excess oil from the engine and dispose of the old oil properly.
Importance of Changing the Oil

Regularly changing the oil in your riding lawn mower is crucial for maintaining its performance and extending its lifespan. Over time, oil can become contaminated with dirt and debris, which can cause damage to the engine. Additionally, old oil can become thick and lose its lubricating properties, making it difficult for the engine to run smoothly.
Other Lawn Care Tips
In addition to changing the oil, there are a few other lawn care tips you should keep in mind to keep your riding lawn mower in top shape:
- Check the air filter regularly and replace it if it is dirty.
- Keep the blades sharp to ensure a clean cut.
- Clean the underside of the mower deck to prevent buildup of grass and debris.
- Store your mower in a dry, covered area when not in use.
By following these tips and regularly changing the oil in your riding lawn mower, you can ensure that your mower will continue to run smoothly and keep your lawn looking its best.
