To learn more about the error codes for this grass-cutting device, just continue to read our article. It has the information you want to know about so you can get your lawn mower up and running as fast as possible. Take a few minutes to see how this information helps you.

Spartan Mower Electric Fault Codes


It looks like Spartan recorded its error codes in its manuals starting in 2018. The list in the 2018 owner’s manual is the same list that is found in the 2022 booklet.

The majority of error codes seem to be the check battery problem with a few parts thrown in from time to time. Those parts will be checked for shorts, check the solenoid, check the headlights for a short, and so on.

The next major error code series is the excessive current or the console internal fault. Both have a sizeable number of error codes associated with them. The codes are very straight forward and you should have no trouble locating the failed part or parts when you see them flashing on your display.

Before you lose your owner’s manual you should rip that page out and put it somewhere you can find it easily and where it won’t get lost or destroyed. Scanning to your computer would be the best option for this.

Whatever you do, do not put it in a place where it will never get lost, as you will never find it again.

In this case, the best place to go for a manual will be the Spartan Mower website. They have a specific web page set up that lists all the manuals you should need.

It is a very easy web page to navigate as you just scroll down to the manual year you want and click on the link. The manual comes up very fast and you will find parts manuals underneath each year as well. Just click here to get to their list of manuals.

Spartan Mower Says An Electrical Fault


Unfortunately, there are far too many codes related to an electrical fault to pin it down. As you can see by the above list, there is a current problem in a majority of error codes.

But you can get a good idea of where the problem lies by looking at the specific code. Code 11 may relate to the topic of the section better than some of the others. You should use a multimeter to test the current level and find where the problem lies.

If the engine will not crank or start, then you have a few sources for the problem and a few solutions to use. The sources are as follows:

- Safety switches not depressed

- Battery installed incorrectly

- Battery is dead or weak

- Blown fuse or circuit breaker

- Engine ground wire lose

- Starter solenoid malfunction

The solutions for these issues are as follows:

- Check all four safety switches.

- Remove the battery and reinstall it correctly. Consult a

dealership if needed.

- Recharge or replace the battery.

- Replace damaged part.

- Tighten the ground wire.

Spartan Mower Electric Fault Code 12

The manual states that this code means that you are having a problem with the solenoid. It specifically says “Check battery condition and connections, check starter solenoid wiring for shorts.”

The starter could be bad, the battery could have been drained of power, the battery is too old, or you have a loose connection somewhere or there is corrosion on some of the terminals or connectors.

You would have to pinpoint the problem by checking each part individually till you find the problem. Then simply address that problem when you do find it. The worst fix will be either a bad battery or a bad starter solenoid.

Spartan Mower Error Code 39


The code says “Console internal fault, some or all power functions inhibited.” This error code may require the services of a technician. But you can check it out yourself to see how severe this problem is.

One owner had this error code and it was the wires on the right side handle that went bad. It also would not stay in the wire harness. The latter problem is easy to fix as all you have to do normally, is squeeze the connectors together for a tighter fit.

If the wire is bad, then replace the wire and maybe the harness if it was damaged at the same time.

Spartan Mower Error Code 44

If you haven’t fully read the table above, then this error code says “Low PTO on current, check PTO wiring and connections.” This code seems to be referring to the new technology lawnmowers are putting on their power products.

The PTO is Power Take-off and it is designed to make the lawn mower safer and more efficient. If you see this code, then the source is one of three possible parts-- the switch, solenoid, and clutch.

The solution is to replace the part or parts that have gone bad on you. You may need a multimeter to test the solenoid and the PTO switch.

How do You Reset The Code On a Spartan Lawn Mower?


To be honest, we could not find this instruction in the manual or on any website that discusses this lawn mower. There are many reset instructions for changing the password, the job timer, and the change oil alert but not for clearing any error codes.

That may be done by stopping the engine and then restarting it after you have finished your repair work. The best thing to do is double-check with Spartan Mowers directly at the link above.

The instructions to start the engine are fairly easy and not complicated to understand or follow:

Before the mower will start, the Safe-To-Start Indicator

must be green.

- Sit in the operator's seat

- Engage the parking brake

- Place control arms into the neutral position

- Disengage the PTO

Watch out for the two switches under the start/stop button. You must press both to start the motor and only press one to stop it. The stop instructions are just as easy as the start but you need to make sure all moving parts have stopped before getting off the mower

Some Final Words

Error codes can be confusing, especially when you are not mechanically inclined. However, on the Spartan Mowers, these error codes seem very easy to understand and pinpoint the area of the problem fairly clearly.

Just download a manual from the website, so you have it on hand and can access it easily when you have a problem. When in doubt, call in a technician to help you. They will have a better idea of how to fix those error codes and where to look.
