Keeping your riding lawn mower in top shape requires regular maintenance, and one crucial task is draining the old oil and replacing it with fresh oil. Not only does this ensure smooth operation, but it also extends the life of your mower’s engine. If you’re unsure about how to drain the oil from your riding lawn mower, don’t worry! This comprehensive guide will walk you through the process step-by-step, making it a breeze for even novice mechanics.
Changing your lawn mower oil is relatively straightforward. It involves locating the drain plug, warming up the engine, and then safely draining the old oil into a suitable container. Once the oil is drained, you’ll need to replace the drain plug, add new oil to the correct level, and start your mower to ensure proper oil circulation.
Gather Your Supplies
Before you begin the process, gather the following supplies:
- Oil drain pan: This is essential for catching the drained oil. A large pan, at least 5 quarts, is recommended to avoid any spills.
- Oil filter wrench: If your lawn mower has an oil filter, you’ll need a wrench to remove it.
- New engine oil: Check your lawn mower manual for the recommended type and viscosity of oil.
- Shop towels: These are handy for cleaning up any spills or drips.
- Gloves: Wear gloves to protect your hands from oil and dirt.
- Safety glasses: Protect your eyes from oil spray and debris.
- Funnel: This will help you pour the new oil into the engine without spilling.
Prepare Your Mower
With your supplies ready, let’s prepare your lawn mower for the oil change:
1. Park the Mower on a Level Surface
Before you start draining the oil, ensure your riding lawn mower is parked on a level surface. This will prevent any oil from spilling out of the drain pan when you loosen the drain plug.
2. Warm Up the Engine
Running the engine for a few minutes will help thin the oil, making it easier to drain. This also allows the oil filter to heat up, improving its ability to release any trapped oil.
Important Note: Do not let the engine run for an extended period before draining the oil. Overheating the engine could lead to burns or damage.
3. Locate the Drain Plug
The drain plug is typically located on the bottom of the engine block. It will be a small, metal plug with a square or hexagonal head. Refer to your owner’s manual if you are unsure of its location.
Drain the Old Oil
Now that your mower is prepared, you can begin draining the old oil:
1. Place the Drain Pan
Position your oil drain pan directly beneath the drain plug. Ensure the pan is large enough to catch all the oil without spilling.
2. Loosen the Drain Plug
Use a wrench to loosen the drain plug. Be careful not to overtighten it when you replace it later.
3. Allow the Oil to Drain Completely
Once the drain plug is removed, allow the oil to drain completely into the pan. This might take a few minutes.
4. Replace the Drain Plug
Once all the oil has drained, replace the drain plug and tighten it securely.
5. Inspect the Drain Plug for Damage
After tightening the drain plug, inspect it for any signs of damage or wear. If there are any signs of wear, replace the drain plug before proceeding.
Change the Oil Filter (If Applicable)
Some riding lawn mowers have an oil filter that needs to be changed with each oil change. Here’s how to do it:
1. Locate the Oil Filter
The oil filter is usually located near the engine block, typically on the top or side.
2. Remove the Oil Filter
Use the oil filter wrench to loosen and remove the old oil filter. Be careful not to overtighten it when you replace it.
3. Dispose of the Old Oil Filter
The old oil filter can be disposed of at a local recycling center or automotive parts store.
4. Install the New Oil Filter
Before installing the new oil filter, apply a thin layer of clean engine oil to the gasket. This will help seal the filter and prevent leaks. Screw the new filter on hand-tight, then give it an additional quarter turn with the wrench to ensure a secure fit.
Add New Oil
After draining the old oil and replacing the filter (if applicable), you’re ready to add fresh oil to your lawn mower.
1. Refer to Your Owner’s Manual
Check your lawn mower’s owner’s manual for the recommended type and quantity of oil for your engine. Use the correct type of oil for your mower.
2. Pour the New Oil
Using a funnel, carefully pour the new oil into the engine oil filler neck until it reaches the “Full” mark on the dipstick.
3. Check the Oil Level
After adding the new oil, check the oil level using the dipstick. Wipe the dipstick clean, insert it fully into the filler neck, and then pull it out again. The oil level should be between the “Full” and “Add” markings on the dipstick.
4. Start the Engine
Once you have added the oil, start the engine and let it run for a few minutes to ensure the oil circulates properly. Check for any leaks around the drain plug or oil filter.
Dispose of Used Oil Properly
Once you’ve completed the oil change, it’s important to dispose of the used oil properly. Do not pour it down the drain or onto the ground.
1. Take Used Oil to a Recycling Center
Many automotive parts stores and recycling centers accept used oil for recycling.
2. Dispose of the Oil Drain Pan
Clean the oil drain pan thoroughly and dispose of it properly.
