Oil Change Schedules for Exmark Zero-Turn Mowers

Why Oil Changes Matter for Your Exmark

Oil keeps your mower's engine running smoothly. Over time, oil breaks down and collects dirt and debris. Regular oil changes help your engine last longer and perform better.

Standard Oil Change Intervals

Most Exmark zero-turn mowers need an oil change every 50 hours of use. If you mow regularly during the season, this usually means changing oil about once a month.

Some newer Exmark models may have longer intervals—check your owner's manual for your specific model. The manual will tell you the exact schedule your mower needs.

More Frequent Changes in Dusty Conditions

If you mow in very dusty or sandy areas, you may need to change oil more often. Dust gets into the oil faster, making it less effective. Consider changing oil every 25 to 40 hours if your mowing area is particularly dusty.

How to Know When It's Time

Check your oil level before each mowing session. If the oil looks dark or dirty, it's time for a change—even if you haven't reached the hour mark yet. Clean oil should be amber or light brown in color.

What You'll Need

• New oil (check your manual for the correct type and amount)
• An oil drain pan
• An oil filter wrench (if your model has a replaceable filter)
• A new oil filter (if applicable)
• Rags or paper towels

Basic Steps for an Oil Change

Warm up the engine for a few minutes, then turn it off and let it cool slightly. This helps the old oil drain better. Locate the drain plug underneath the mower deck, remove it, and let the oil drain into your pan. Replace the drain plug. Add new oil slowly while checking the level with the dipstick. Don't overfill.

If your Exmark has an oil filter, replace it at the same time. Your owner's manual will show you where it's located and how to remove it.

Keeping Track

Write down the date and hour count each time you change the oil. This helps you stay on schedule and remember when the next change is due. Many people keep a simple log on their mower or in a notebook.

Questions About Your Model

Your Exmark owner's manual is the best resource for your specific mower. It includes the exact oil type, capacity, and change intervals for your model. If you no longer have the manual, you can often find it online using your mower's model number.
