Spartan mowers are known for their high-quality build and reliable performance.
However, like any other piece of machinery, they can develop issues over time.
One of the most common problems reported by Spartan mower owners is Error 39.
In this post, we will discuss everything you need to know about Spartan Mower Error 39, including its causes, symptoms, and possible solutions.
Let’s dive in.

What is Spartan Mower Error 39?
Spartan mower error 39 is a code that appears on the control panel of the machine when it encounters a hydraulic drive system problem.
It indicates an issue with the hydraulic drive system of the mower. This can cause the mower to stop working or operate sluggishly, making it difficult to mow the lawn.
Causes of Spartan Mower Error 39
There are several reasons why your Spartan mower may display Error 39. Some of the most common causes include:
1. Low hydraulic fluid level
The hydraulic fluid is responsible for powering the hydraulic drive system. If the fluid level is low, it can cause the system to malfunction and trigger Error 39.
2. A faulty hydraulic pump
The hydraulic pump is responsible for pressurizing the hydraulic fluid and sending it to the drive system.
If the pump is faulty or damaged, it can cause the system to fail and display Error 39.
3. Damaged hydraulic hoses
The hydraulic hoses carry the fluid from the pump to the drive system. If these hoses are damaged or cracked,
they can cause the system to malfunction and trigger Error 39.
4. Dirty hydraulic fluid
If the hydraulic fluid is dirty or contaminated, it can cause the system to malfunction and display Error 39.

How to check hydraulic fluid on Spartan Mower
To check the hydraulic fluid on a Spartan mower, you’ll need to follow these general steps. Please note that the specific procedure may vary slightly depending on the model and year of your Spartan mower.
So it’s essential to consult your mower’s manual for precise instructions. Here’s a basic guide:
Tools and Materials You’ll Need:
- Safety glasses or goggles
- Clean rags or paper towels
- A funnel (optional)
- A container for collecting used hydraulic fluid (if necessary)
Steps:
- Safety First: Before you begin, make sure your Spartan mower is on a level surface and the engine is turned off. Also, wear safety glasses or goggles to protect your eyes.
- Locate the Hydraulic Reservoir: The hydraulic reservoir is typically located near the rear of the mower, often underneath the seat or the rear cover. Refer to your owner’s manual if you’re unsure of its exact location.
- Clean the Area: Use a clean rag or paper towel to wipe around the hydraulic reservoir’s cap and surrounding area. This prevents dirt and debris from contaminating the hydraulic fluid when you open it.
- Remove the Cap: Carefully remove the cap from the hydraulic reservoir. Depending on your mower model, it may have a screw-on cap or a dipstick-style cap. Be cautious not to drop any dirt or debris into the reservoir when removing the cap.
- Check the Fluid Level: For mowers with a dipstick-style cap, wipe off the dipstick, reinsert it into the reservoir, and then pull it out again to check the fluid level. There should be markings on the dipstick indicating the proper fluid level. For mowers with a screw-on cap, you may need to use a flashlight to inspect the fluid level visually. The fluid should be close to the top but not overflowing.
- Add hydraulic fluid (if needed): If the fluid level is low, you’ll need to add hydraulic fluid. Use a funnel to prevent spills. Refer to your owner’s manual to find the correct type of hydraulic fluid for your mower. Slowly pour the fluid into the reservoir, periodically checking the level to avoid overfilling.
- Secure the Cap: Once you’ve checked or added hydraulic fluid, securely reattach the cap to the reservoir.
- Dispose of Old Fluid (if necessary): If you had to remove old hydraulic fluid, make sure to dispose of it properly according to your local regulations. Most auto parts stores or recycling centers accept used hydraulic fluid.
- Test the Mower: Start the mower and engage the hydraulics to ensure they are functioning correctly. Check for any leaks around the reservoir or hydraulic lines. If you notice any issues, consult your owner’s manual or consider seeking professional assistance.
- Record Maintenance: It’s a good practice to record the date and any maintenance performed in your mower’s log or manual for future reference.
