Summary
- The hydraulic fluid reservoir is typically located on the side of the mower deck, near the engine.
- If the fluid level is below the “Full” mark, you need to add more hydraulic fluid.
- Pour the recommended hydraulic fluid slowly into the reservoir, keeping an eye on the dipstick.
Maintaining the hydraulic fluid level in your Exmark zero-turn mower is crucial for smooth operation and longevity. Low hydraulic fluid can lead to sluggish performance, overheating, and even damage to the hydraulic system. This comprehensive guide will walk you through the process of checking and topping off your Exmark zero-turn’s hydraulic fluid, ensuring you can keep your mower running efficiently.
Safety First: Essential Precautions
Before you start checking your hydraulic fluid, it’s essential to prioritize safety. Here are a few things to keep in mind:
- Park on a Level Surface: Ensure your Exmark zero-turn mower is parked on a level surface with the parking brake engaged. This will prevent any accidental movement while you’re working.
- Turn Off the Engine: Always switch off the engine and wait for it to cool down completely before checking or adding hydraulic fluid. Hot fluid can cause burns, and a running engine poses a safety hazard.
- Wear Protective Gear: Use gloves to protect your hands from any potential spills or dirt. Safety glasses are also recommended to shield your eyes.
Locate the Hydraulic Fluid Reservoir
The hydraulic fluid reservoir is typically located on the side of the mower deck, near the engine. It’s usually a black or gray plastic container with a dipstick. Some Exmark models might have the reservoir located in a different position, so consult your owner’s manual for specific instructions.
Checking the Hydraulic Fluid Level
1. Clean the Dipstick: Remove the dipstick and wipe it clean with a rag or paper towel. This ensures an accurate reading.
2. Insert the Dipstick: Fully insert the dipstick back into the reservoir.
3. Read the Fluid Level: Carefully remove the dipstick and check the fluid level. The dipstick will have markings indicating the “Full” and “Low” levels.
4. Add Fluid if Needed: If the fluid level is below the “Full” mark, you need to add more hydraulic fluid.
Choosing the Right Hydraulic Fluid
Using the correct type of hydraulic fluid is essential for your Exmark zero-turn mower. The wrong fluid can damage the hydraulic system. Consult your owner’s manual or contact your local Exmark dealer for the recommended hydraulic fluid type.
Adding Hydraulic Fluid
1. Locate the Fill Port: The fill port is usually located on the top of the hydraulic fluid reservoir. It may have a cap or a screw-on lid.
2. Remove the Cap: Carefully remove the cap or lid from the fill port.
3. Add Fluid Slowly: Pour the recommended hydraulic fluid slowly into the reservoir, keeping an eye on the dipstick. Do not overfill the reservoir.
4. Replace the Cap: When the fluid level reaches the “Full” mark, replace the cap or lid securely.
Checking for Leaks
After adding hydraulic fluid, inspect the reservoir and surrounding areas for any leaks. Look for signs of fluid dripping or pooling. If you notice any leaks, it’s important to address them immediately to prevent further damage to the hydraulic system.
Maintaining Your Hydraulic System
Regularly checking and maintaining your hydraulic fluid level is crucial for optimal performance and longevity of your Exmark zero-turn mower. Here are some additional tips for maintaining your hydraulic system:
- Inspect the Filters: Check your hydraulic filters regularly and replace them as needed. Dirty filters can restrict fluid flow and damage the system.
- Change the Fluid: Change the hydraulic fluid every 100 hours of operation or annually, whichever comes first. This helps remove contaminants and ensure optimal performance.
- Avoid Overheating: Allow the engine to cool down completely before shutting it off. Overheating can damage the hydraulic system.
The Importance of Regular Maintenance
Regularly checking and maintaining your Exmark zero-turn’s hydraulic fluid is not just about keeping your mower running smoothly, it’s about extending its lifespan. Neglecting this simple task can lead to costly repairs and downtime.
