The warm weather is here, and that means it’s time to get your lawn mower out of storage and ready for action. But before you fire it up, take a minute to make sure you’re giving your mower the proper maintenance it needs. One of the most important things you can do is to change the oil regularly.
Changing the oil in your lawn mower might seem like a daunting task, but it’s actually quite simple. This article will walk you through the entire process, from gathering the necessary tools to properly disposing of the used oil. We’ll cover everything you need to know to keep your mower running smoothly and extend its lifespan.
Overview of Changing Lawn Mower Oil
Changing the oil in your lawn mower is essential for its longevity and performance. It lubricates the engine’s moving parts, preventing wear and tear. Over time, the oil breaks down and becomes contaminated with dirt, metal shavings, and other debris. This contaminated oil can clog engine parts and lead to serious problems. By regularly changing the oil, you remove this contamination and ensure your mower continues to run smoothly.
Gather Your Supplies
Before you start changing the oil, gather the following supplies:
- New lawn mower oil: The type of oil you need will be specified in your owner’s manual. Most gas-powered mowers use SAE 30 oil, but check the manual to be sure.
- Oil drain pan: This will catch the used oil when you drain it from the mower.
- Oil filter wrench (if applicable): Some lawn mowers have oil filters that need to be changed with each oil change. If your mower has an oil filter, you’ll need an oil filter wrench to remove it.
- New oil filter (if applicable): If your mower has an oil filter, you’ll need to purchase a new one.
- Gloves: Protect your hands from the used oil.
- Rag: For cleaning up any spills.
- Owner’s manual: To refer to for specific instructions for your model.
Preparing the Lawn Mower
1. Locate the Oil Drain Plug
Locate the oil drain plug on your mower. It’s usually located on the bottom of the engine block, often near the crankcase.
2. Warm Up the Engine
A warm engine makes it easier to drain the oil. Start the mower and let it run for a few minutes. Don’t let it overheat! This will make the oil thinner and easier to drain.
3. Turn Off the Engine and Disconnect the Spark Plug
Once the engine is warmed up, turn it off and disconnect the spark plug wire to prevent the engine from starting accidentally.
Draining the Oil
1. Place the Oil Drain Pan Under the Plug
Place the oil drain pan directly under the oil drain plug.
2. Unscrew the Oil Drain Plug
Using a wrench, carefully unscrew the oil drain plug. The oil will start draining into the pan.
3. Allow Oil to Drain Completely
Allow the oil to drain completely before tightening the drain plug again.
Changing the Oil Filter (if applicable)
1. Locate the Oil Filter
If your mower has an oil filter, it will be located near the engine block.
2. Remove the Oil Filter
Use an oil filter wrench to remove the old oil filter.
3. Install the New Oil Filter
Before installing the new oil filter, apply a light coat of oil to the rubber seal. Thread the new filter onto the filter housing, making sure it is tight. Do not overtighten.
Adding New Oil
1. Remove the Oil Fill Cap
Locate the oil fill cap, usually on the top of the engine block. Remove the cap.
2. Pour in the New Oil
Pour the new oil into the oil fill cap opening, slowly and carefully, making sure not to overfill. Refer to your owner’s manual for the correct amount of oil to add.
3. Check the Oil Level
Once you’ve added the new oil, check the dipstick to ensure the oil level is at the correct level.
Starting the Mower and Checking for Leaks
1. Reconnect the Spark Plug Wire
Reconnect the spark plug wire.
2. Start the Mower and Check for Leaks
Start the mower and let it run for a few minutes. Keep a close eye out for any oil leaks.
3. Shut Down the Mower and Dispose of Used Oil
Shut down the mower and allow it to cool down.
Dispose of the used oil properly. Never pour used oil down the drain. Check with your local municipality about safe and responsible disposal methods.
Tips for Maintaining Your Lawn Mower
Here are some additional tips for keeping your lawn mower in tip-top shape:
- Change the oil every 25 hours of operation or at the beginning of each season. If you mow less frequently, you can change the oil once a year.
- Clean your mower after each use. This will help to prevent dirt and debris from accumulating on the engine and other parts.
- Inspect your mower regularly for wear and tear. Replace any worn or damaged parts promptly.
- Store your mower properly during the off-season. Cover it with a tarp or store it in a shed to protect it from the elements.
