How to Change the Oil and Filter on a Husqvarna Zero Turn Mower

Maintaining a Husqvarna Zero Turn Mower in top condition requires regularly changing the engine oil and filter. This task is important for keeping the engine running smoothly and lasting longer. Let’s discuss why changing the oil and filter is important, which oil and filter to use, how to do it, and how to dispose of the old oil and filter properly.

Why It’s Important to Change the Oil and Filter

The engine oil lubricates the engine’s parts, helps cool the engine, and cleanses dirt. However, over time, the oil breaks down and can’t do its job as well, which could lead to engine problems or damage. The filter catches dirt and debris to keep them out of the engine. But it can get clogged and needs to be replaced to work correctly.

Recommended Oil and Filter

For most Husqvarna Zero Turn Mowers, it’s best to use SAE 30 oil in warm weather and 10W-30 oil when it’s colder. These types are good for different temperatures, but you should check your mower’s manual to see what’s best for your specific model.

The right filter depends on your mower’s engine model. It’s a good idea to look at the manual or ask a Husqvarna dealer to find out which filter you need.

Tools and Steps to Change the Oil and Filter

You’ll Need:

  • The right type and amount of oil
  • A new oil filter
  • An oil pan to catch the old oil
  • Wrenches or pliers
  • Rags for cleaning up
  • A funnel for pouring oil


Get the Engine Ready: Warm up the engine for a few minutes to improve the oil flow. Then, turn off the engine and disconnect the spark plug wire for safety.

Drain the Old Oil: Put the oil pan under the mower’s drain plug. Unscrew the plug with a wrench and let the old oil drain out. Put the plug back in place tightly.

Change the Filter: Use pliers or a filter wrench to remove the old oil filter. Be ready to catch any oil that spills with your rags. Put a little bit of new oil on the rubber seal of the new filter before screwing it on. Make it hand-tight, then give it a little more turn with the wrench.

Add New Oil: Use a funnel to pour new oil into the engine. Fill it up to the right level, but be careful not to overfill. Check the level with the dipstick. Put the spark plug wire back on when done.

Disposal and Safety Tips

Proper Disposal: Don’t throw away the old oil and filter in the trash. Take them to a place that recycles oil and filters. It’s better for the environment and is usually required by law.

Be Safe: Work in a place with lots of air, and be careful not to spill oil, which could start a fire. Wear gloves to protect your hands.

Keep Up with Maintenance: Look at your mower’s manual to know how often to change the oil and filter. Staying on top of this keeps your mower running well for a long time.

By following these guidelines, changing the oil and filter on your Husqvarna Zero Turn Mower can be straightforward, ensuring your mower stays in great shape and serves you well for many years.

Additional Safety Tips:

When mowing the lawn, safety should always be a top priority. These safety tips are mandatory to avoid any incident while mowing your lawn:

Wear Appropriate Clothing:

This includes closed-toe shoes, long pants, and safety goggles. Avoid wearing loose clothing that could get tangled in the mower.

Inspect the Lawn Before Mowing:

Look out for and remove any debris, such as rocks, branches, or toys, which could be flung by the mower’s blades.

Keep Children and Pets Away:

Establish a safe zone well away from the mowing area and never allow children or pets to play near a running mower.

Use the Right Mower for the Job:

Choose a mower that’s suitable for your lawn’s size and terrain. Pay special attention to traction if your lawn has steep slopes to prevent the mower from tipping.

Avoid Mowing in Wet Conditions:

Wet grass can be slippery, increasing the risk of accidents. Wait for your lawn to dry before mowing.

Watch Your Speed and Stability:

Maintain a controlled speed, especially when making turns. Be extra cautious on uneven terrain to avoid accidents.

Turn Off the Mower When Not in Use:

Never leave a running mower unattended. Always wait for the blades to completely stop before clearing any debris.

Keep Hands and Feet Clear:

Never attempt to clear grass or debris from the mower while it’s running. Keep a safe distance from all moving parts.

Stay Hydrated and Take Breaks:

Especially in hot weather, staying hydrated is crucial. Regular breaks can help prevent fatigue and keep you alert.

Use Hearing Protection:

Consider using earmuffs or earplugs, particularly during long mowing sessions, to protect your hearing.

Adopting these precautions can make a huge difference in ensuring a safe and enjoyable lawn mowing experience.

Bottom Line

Husqvarna zero-turn mowers are excellent tools for maintaining a pristine lawn, but they can experience common problems like any other machinery. By following these simple troubleshooting steps and sourcing quality replacement parts, you can keep your mower in top condition and ensure your lawn stays beautifully manicured throughout the mowing season.
