Issues With Parts & Solution

In this section, we’d like to get a little bit closer with the john Deere gator. And find out more about the most common problems that take place with the parts. Along with the solution if there’s any.

Corrosion in Battery

If you notice that the Gator is for some reason stuttering to start or just stops out of nowhere, the first area to check would be the batteries. Those can have corrosion hence the problem. You may find the buildup of corrosion on the battery panel more specifically.

And to check you definitely require removing the access panel of the battery. It should be beneath the passenger seat. Simply pull the latch that is also located beneath the passenger seat and the access should be granted.

Now once you get the panel, it’s time to first remove the cables of the battery. Make sure you use a wire brush to clean the corrosion if you find it.

And also, don’t forget to apply some good battery terminal grease. In some cases, it may even require cable replacement. Especially if the corrosion seems too acute.

Fuse Being Blown

This is also going to erupt the usage of gators by not allowing them to start smoothly. And to check whether or not a blown fuse is responsible, you need to access the fuse box.

It should be right underneath the instrument panel. Look behind the brake pedal. And then you can see the fuses, and check whether any look blown. And if they do, you have to replace the blown ones.

Spark Plug Can Get Loose or Damage

Spark plug typically will stay on the engine’s top side. if those are loose or damaged, the gator will have trouble operating. To find out if there is any looseness, you need to wiggle the wires slightly. Any of those coming losses basically means what we guessed.

You can simply solve the problem by firmly pressing the spark plug wires into the spark plugs. However, if the spark plugs are severely damaged, you will need to get new ones. Use a wrench for removing and installing spark plugs to fix the issue.

Damaged Fuel Filter

And the final one is the fuel filter. Again, this will require you to raise the cargo box so that the plastic fuel filter seems accessible it should be right in the middle of the fuel hose, which typically is black in color.

The fuel hose is in charge of jointing the fuel tank with a carburetor. So, once you find that you need to use a screwdriver and unscrew both hose clamps available on the filter’s either side. Then sliding the filter out should be easy.

Simply install a new filter in place of the damaged one. And while you do so, make sure you are taking notes of the arrow that shows the filter is downwards toward the engine. Carefully slide the clamps. And then tighten using the tool.
