How to Change Oil on a Troy Bilt Lawn Mower(In 5 Quick Steps)

One of the most critical maintenance tasks is regularly changing the engine oil. Fresh oil keeps the engine lubricated, reduces wear, and helps it run smoothly.

In this guide, we’ll walk you through the process of changing the oil on a Troy-Bilt lawn mower, whether it’s a push mower, a self-propelled model, or a riding mower. With clear instructions and practical tips, you’ll be able to tackle this task with confidence, even if you’re a beginner.

How to Change Oil on a Troy Bilt Lawn Mower

Tools and Materials Needed:

Before you begin, gather the following items to make the oil change process smooth and efficient:

• New engine oil: recommended oil type (commonly SAE 30 or 10W-30 for most models). You’ll typically need about 20-24 ounces for push or self-propelled mowers and up to 48 ounces for riding mowers.
• Oil filter (if applicable): Some riding mowers have an oil filter that should be replaced during the oil change.
• Oil drain pan: A low-profile container to catch the old oil.
• Wrench or socket set: For removing the drain plug (if your mower has one).
• Funnel: To pour new oil into the engine without spilling.
• Rags or paper towels: For cleaning up spills and wiping down parts.
• Gloves: To keep your hands clean and protected.
• Oil filter wrench (optional): For riding mowers with an oil filter.
• Jack and jack stands (for riding mowers): To elevate the mower safely.

Step 1: Prepare the Mower

1. Run the engine for a few minutes: Warm oil flows more easily, making it easier to drain. Run the mower for 3-5 minutes, then turn it off and disconnect the spark plug to prevent accidental starts.
2. Position the mower: For push or self-propelled mowers, place it on a flat surface. For riding mowers, park on a level surface and use a jack to lift the front end slightly, securing it with jack stands for safety.
3. Clean the area around the oil fill cap: Wipe away dirt and grass clippings to prevent debris from entering the engine.

Step 2: Drain the Old Oil

1. Locate the oil drain plug or dipstick: On push or self-propelled Troy-Bilt mowers, the oil drain plug is typically underneath the deck or near the engine base. For riding mowers, it’s often on the side or bottom of the engine. If your mower doesn’t have a drain plug, you’ll drain the oil through the dipstick tube.
2. Place the oil drain pan: Position the pan directly under the drain plug or dipstick tube to catch the oil.
3. Remove the drain plug (if applicable): Use a wrench to loosen and remove the plug. Allow the oil to drain completely, which may take a few minutes. If there’s no drain plug, tilt the mower carefully (spark plug side up) to pour the oil out through the dipstick tube into the pan.
4. Replace the drain plug: Once the oil has drained, reattach the plug securely.

Step 3: Replace the Oil Filter (Riding Mowers Only)

If your Troy-Bilt riding mower has an oil filter, now is the time to replace it:

1. Locate the oil filter: It’s usually a cylindrical component near the engine.
2. Remove the old filter: Use an oil filter wrench to unscrew it. Be prepared for some oil to drip out.
3. Prepare the new filter: Apply a thin layer of new oil to the rubber gasket on the new filter to ensure a tight seal.
4. Install the new filter: Screw it on by hand until snug, then tighten it slightly with the wrench (avoid over-tightening).

Step 4: Add New Oil

1. Check the oil capacity: Refer to your Troy-Bilt manual for the correct oil type and amount. Most push mowers take 20-24 ounces, while riding mowers may require up to 48 ounces.
2. Use a funnel: Place the funnel in the oil fill tube (usually where the dipstick is located).
3. Pour the new oil: Slowly add the recommended amount of oil, checking the dipstick periodically to avoid overfilling.
4. Check the oil level: Insert the dipstick, remove it, and verify the oil level is within the marked range. Add more oil if needed.

Step 5: Clean Up and Test

1. Wipe down the mower: Clean any spilled oil with rags or paper towels.
2. Reconnect the spark plug: Ensure it’s securely attached.
3. Start the mower: Run it for a minute to circulate the new oil and check for leaks.
4. Dispose of old oil properly: Pour the used oil into a sealed container and take it to a local recycling center or auto shop that accepts used oil.
