John Deere makes very reliable machines, not only to work in the fields but also multi-functional vehicles like the Gator XUV 825i.

This crossover utility vehicle is a good investment, but like all machines, it is not without flaws.

Some users complain about problems with the clutch, the fuel pump, and the 4WD function and also noticed that sometimes the gator runs rough.

Let’s dive into each of these issues and see what can be done to fix them. 

The most common problems with John Deere Gator 825i

We had the chance to try the John Deere Gator 825i and we can confirm it is a very good utility vehicle that can greatly improve your daily workload.

However, we can also confirm that it has a fair share of flaws, some of which only appear after some time.

Of course, these problems didn’t appear all at once, but we ran some tests after specifically researching the users’ complaints about the XUV 825i.

That’s why now we can tell you all about troubleshooting and fixing the most common John Deere Gator 825i problems.

1. Clutch problems

The primary clutch seems to be one of the biggest issues with this gator model from John Deere.

Many users complain about the clutch failing to disengage, making it hard to shift and sometimes just making it impossible to do any kind of movement at all.

Apparently, the clutch of the xuv 4×4 825i is easily damaged, so if you’re towing heavy load regularly there’s a good chance that’s the reason why it doesn’t work properly.

Unfortunately, there’s not much you can do for a malfunctioning clutch except to replace it, and you might want to give your John Deere dealer or a professional a call as well.

2. Starting problems

Unlike some John Deere tractors like the 1025r, which start smoothly after the engine has warmed up, the gator 825i has the opposite problem.

Sometimes, the gator starts well even with a cold engine but turns off as soon as it warms up. This can happen even when it just has a few dozens of hours on its back, so it can be rather bothersome.

You can try to troubleshoot this issue by following one or more of the following tips:

  • Take out the intake sensors and clean them thoroughly using a contact cleaner;
  • Check the engine for injector dirt. If necessary, clean the engine using injector cleaner;
  • Clean each spark plug or replace them;
  • Drain the fuel and change the fuel filter;
  • Change your fuel into an ethanol-free type.

3. 4WD function problems

Another fairly common issue with this gator vehicle is the inability of the 4WD function to engage at times.

This essentially means that sometimes you might be unable to use the 4-wheel drive function properly.

There are many reasons behind this issue, so in order to find the cause you will need to take into consideration your specific environment and driving habits.

For example, maybe you’re recently been driving through heavy snow, or you have some loose connections, or two tires have been stuck for quite some time.

Whatever the reason may be, here are some ways to troubleshoot it:

  • Check the circuit fuse and clean its socket. Try to engage the 4WD again when you start the engine;
  • With the switch on, check that the rear wheels spin 15% faster than the front ones;
  • Leave the gator idle for some time, then try to start the 4-wheel function again;

When everything else fails, you can always check the manual, which has a specific section for the 4WD function.

You can also refer back to your John Deere dealer, who will surely provide the best solution for your specific issue.

4. Fuel pump problems

The fuel pump issue is another winner among the most common problems of this JD gator.

What usually happens is, that you turn on the key, the connection goes up to 12volts and then stops even before the pump can kick in.

At that point, the relay switch goes off and the engine fails to start completely.

Here are a few ways to troubleshoot this problem:

  • First of all, check the wiring to see if the issue lies in the connection to the fuel pump or the ECU;
  • You might also want to try replacing the connector of the fuel pump;
  • Connect a 60-psi gauge with a 1/4 hose, but make sure to keep the pressure between 45-50 psi while you connect it;
  • As a last resort, try changing the relays of your vehicle and see if anything changes.

None of these worked out? It’s time to bring your gator xuv 825i to get professionally checked.

5. Running rough

With this gator utility vehicle, running rough is a rather common problem.

The issue is that the gator will need either to start and will keep needing more ether to keep it running, while at the same time pumping gas constantly.

Also, it might not start if the engine is not warmed up, but even once it’s warmed up it won’t run smoothly, and if you turn it off, it won’t start again until the engine has cooled down.

If you wish to troubleshoot this issue on your own, try the following tips:

  • Use a pressure gauge to test the fuel pressure;
  • Check all the wiring to see if there’s anything broken, corroded, or torn;
  • Check the fuel pump itself, and the injectors;
  • Check the air filters and clean or replace them if necessary;
  • Lastly, if the gator hasn’t been running for some time, you may want to check the fuel itself.

John Deere Gator 825i Problems: are they a deal-breaker? 

They’re not! The gator 825i is a performance-driven utility vehicle for the truly adventurous.

It delivers the perfect balance between a work vehicle and a recreational vehicle, and you’re going to want to go places with this one.

Despite some users complaining about issues, mainly with the clutch, the fuel pump, and the 4WD function, the benefits of the 825i greatly outnumber its flaws.

Of course, before making an important purchase like this you should take your time evaluating the pros and cons, but these will-they-happen-won’t-they-happen issues should totally not stop you if you want to go for it!
