This comprehensive guide will take you through the steps, from preparing your equipment to disposing of the used oil safely.
Changing the oil in your lawnmower isn’t a complicated process. It requires only a few simple tools and a little time. You’ll be able to tackle this task with confidence by following the steps outlined in this guide, ensuring your mower remains in optimal condition for a long and trouble-free season.
Preparing for the Oil Change:
Before you start draining the oil, you’ll need to gather a few supplies and make sure your lawnmower is ready.
1. Gather Your Tools:
- Oil drain pan: This is a must-have for catching the used oil. Make sure it’s large enough to hold the full amount of oil in your mower’s engine.
- Wrench: You’ll need a wrench that fits the oil drain plug on your mower. The size will vary depending on the model, so consult your owner’s manual for the correct size.
- New oil: Choose the right type of oil for your mower’s engine. Refer to your owner’s manual for the recommended viscosity and type (e.g., SAE 30 or 10W-30).
- Oil funnel: This helps prevent spills when pouring the fresh oil into the engine.
- Gloves: Protect your hands from the used oil and potential spills.
- Rag: Use this to wipe up any spills and clean the oil drain plug.
2. Warm Up the Engine:
- Safety First: Ensure the mower is on a level surface and the engine is turned off.
- Warm-up: Start the engine and let it run for a few minutes. This helps the oil thin out, making it easier to drain.
- Shut Off: Turn off the engine and allow it to cool for a few minutes before proceeding.
3. Position for Drainage:
- Stable Surface: Place your mower on a level surface. You might want to position a piece of cardboard or a drop cloth under the drain plug to prevent any spills from staining your driveway or garage floor.
Draining the Old Oil:
Now that your equipment is ready and the engine has cooled slightly, you can proceed to drain the oil.
1. Locate the Drain Plug:
- Consult Manual: Refer to your lawnmower’s owner’s manual to locate the drain plug. It is typically found on the bottom of the engine block.
- Look for a Hexagon: The drain plug is usually a hexagonal bolt.
2. Unscrew the Drain Plug:
- Wrench: Use your wrench to loosen the drain plug. Turn it counter-clockwise until it is fully removed.
- Let it Drain: Let the oil drain completely into the catch pan. This may take a few minutes.
3. Replace the Drain Plug:
- Clean: Wipe the drain plug and its threads clean with a rag. This removes any dirt or debris that could hinder a proper seal.
- Tighten: Re-install the drain plug and tighten it securely. Avoid over-tightening, which could damage the plug or the engine block.
Refilling with New Oil:
The old oil is drained, and now it’s time to add the fresh stuff.
1. Locate the Fill Hole:
- Manual Guidance: Again, consult your lawnmower’s owner’s manual to find the oil fill hole. It is usually located on the top of the engine block.
- Dipstick: The oil fill hole is typically marked with a dipstick, which allows you to check the oil level once you’ve added the new oil.
2. Pour New Oil:
- Clean Funnel: Use a clean oil funnel to pour the fresh oil into the fill hole.
- Check Level: Refer to your manual for the correct oil capacity. Add oil until it reaches the “full” mark on the dipstick.
Finishing Touches:
The oil change is almost complete. Here are a few final steps to ensure everything is in order.
1. Check for Leaks:
- Engine Running: Start the engine for a brief moment to check for any leaks.
- Inspection: Carefully inspect the oil drain plug and surrounding areas for any signs of oil seepage.
2. Dispose of Used Oil Properly:
- Environmentally Friendly: Never pour used oil down the drain or into the ground.
- Recycling Options: Most auto parts stores or waste management facilities offer oil recycling programs. Contact your local municipality to find the nearest oil recycling location.
Maintenance Schedule and Tips:
While this article focuses on how to take oil out of a lawn mower, it’s also important to consider a regular oil change schedule and other maintenance tips to keep your mower running smoothly.
1. Oil Change Frequency:
- Consult Manual: The frequency of oil changes depends on the type of mower, the amount of usage, and the conditions in which it’s used.
- General Guidelines: As a general rule of thumb, change the oil every 25 hours of operation or at least once a year, whichever comes first.
2. Other Maintenance Tips:
- Air Filter: Regularly clean or replace the air filter to prevent dust and debris from clogging the engine.
- Spark Plug: Check and clean or replace the spark plug as needed.
- Blade Sharpening: Sharp blades help make a clean cut and prevent engine strain.
