The warm weather is here, and that means it’s time to fire up the lawnmower and get those blades whizzing. But before you start mowing, it’s crucial to ensure your trusty push mower is in tip-top shape. One of the most important maintenance tasks you can perform is changing the oil. This article will guide you through the process, step by step, so you can keep your mower running smoothly all season long.

Changing the oil in your push lawn mower is a relatively simple task that can be done in under 30 minutes. You’ll need a few basic tools, some fresh oil, and a little bit of time. By following these instructions, you’ll ensure your mower’s engine runs efficiently and lasts for years to come.

Gathering Your Supplies: A Quick Checklist

Before you start, gather the necessary supplies. Here’s what you’ll need:

  • New engine oil: Check your owner’s manual to determine the correct type and viscosity of oil for your mower.
  • Oil drain pan: This will catch the old oil as you drain it.
  • Oil filter wrench (if applicable): Some mowers have oil filters that require a wrench for removal.
  • Wrench or socket: You’ll need this to loosen the drain plug.
  • Rag or shop towels: Use these to clean up any spills.
  • Gloves: Protect your hands from dirt and oil.
  • Funnel: To help pour the new oil into the engine.
  • Owner’s manual: This will provide specific instructions for your model.

Step 1: Preparing Your Work Area

First things first, choose a safe and clean workspace. Ideally, a level, paved surface like a driveway or patio is best. This will make it easier to access the underside of the mower and prevent any spills from contaminating the ground.

1.1: Safety First – Let the Engine Cool Down!

Crucially, ensure your mower’s engine has completely cooled down before you begin. Working on a hot engine poses a significant risk of burns.

1.2: Position the Mower for Easy Access

Once your mower is cool, position it on a level surface with the engine facing upward. This will make the drain plug easily accessible.

Step 2: Draining the Old Oil

Now it’s time to drain the old oil. Here’s how:

2.1: Locate the Drain Plug

Refer to your owner’s manual to identify the drain plug. It’s typically located on the underside of the engine, usually near the bottom.

2.2: Position the Drain Pan

Place your drain pan directly beneath the drain plug to catch the used oil.

2.3: Loosen the Drain Plug

Carefully loosen the drain plug with your wrench or socket. Be cautious not to overtighten it when you replace it later.

2.4: Allow the Oil to Drain Completely

Let the oil drain completely into the pan. This might take a few minutes.

2.5: Tighten the Drain Plug

Once the oil has completely drained, tighten the drain plug securely using your wrench or socket.

Step 3: Changing the Oil Filter (If Applicable)

Some push mowers have an oil filter. If yours does, you’ll need to replace it as well.

3.1: Locate the Oil Filter

The oil filter is usually located near the engine, often on the side or top.

3.2: Remove the Old Oil Filter

Use an oil filter wrench, if necessary, to remove the old oil filter. Turn it counter-clockwise to loosen it.

3.3: Dispose of the Old Filter Properly

Discard the old oil filter in a responsible manner. Do not dispose of it in the trash. Check with your local waste disposal facility for proper disposal methods.

3.4: Install the New Oil Filter

Apply a small amount of clean engine oil to the rubber seal of the new oil filter. Screw the new filter onto the filter housing, ensuring it’s securely tightened.

Step 4: Adding New Oil

Now it’s time to fill your mower with fresh oil.

4.1: Check the Oil Dipstick

Locate the oil dipstick on the top of the engine. Remove it and wipe it clean.

4.2: Use a Funnel for Accurate Filling

Insert the funnel into the oil fill opening and carefully pour the new oil into the engine. Don’t overfill it. Consult your owner’s manual for the correct amount of oil to add.

4.3: Check the Oil Level

Once you’ve added the correct amount of oil, replace the dipstick and check the oil level. The oil level should be near the “full” mark on the dipstick.

Step 5: Final Touches and Cleanup

You’re almost done! Here’s what to do next:

5.1: Dispose of Used Oil Safely

Dispose of the used oil properly. Do not pour it down the drain or into the trash. Check with your local waste disposal facility for the proper disposal methods.

5.2: Clean Up Any Spills

Wipe up any oil spills with a rag or shop towels.

5.3: Start the Mower Briefly

Once you’ve cleaned up, start the mower briefly to ensure that oil is circulating correctly.

Final Thoughts: Keeping Your Mower in Top Shape

Changing the oil in your push lawn mower is a simple but crucial maintenance task. By performing this regularly, you’ll extend the life of your mower and keep it running smoothly. Remember to check your owner’s manual for specific instructions and recommendations for your model.

Here are some additional tips to keep your mower in top shape:

By following these tips and changing the oil regularly, you can ensure that your push lawn mower is ready to tackle any task. Enjoy a beautiful, well-maintained lawn all season long!
