By Published On: April 10, 2023

Are you having problems with your John Deere 325g skid steer? If so, you’re not alone. Many users of this machine have encountered a variety of issues, ranging from the minor to the major. In this blog post, we’ll be looking at the five biggest problems with the John Deere 325g skid steer and offering advice on how to fix them. Read on to learn more about the common John Deere 325g problems and what you can do to address them.

Problem #1: Leaking Hydraulic Fluid

There are a lot of moving parts powered by hydraulics on your John Deere 325g skid steer. Fittings will gets damaged or loosened which will cause a leak. These leaks and the subsequent low hydraulic fluid levels can be the beginning of much bigger problems. You must maintain proper fluid levels.


Checking your hydraulic fluid levels needs to be a daily routine for your operators. You will be able to spot leaks quickly and keep bigger issues from arising if you maintain a finger on the pulse. Sometimes you can spot the location of leaks where dust is collecting and sticking to leaking fluid. If you maintain a practice of checking fluid levels every day and you become familiar with the locations of your fittings, you will be able to maintain this from turning into bigger problems.

Problem #2: Engine Overheating

The older your skid steer is the more likely you are to encounter an overheating issue. This is because your radiator has collected dust and other particles which are preventing it from doing its job–cooling.


You’ll want to start by frequently cleaning your radiator and the reversible fan. Set this on a monthly schedule so that you know it’s getting done enough. We recommend using a cleaning solution that will not only get the dirt and dust but will also remove grease and any other sticky substances.

A deeper dive into the cooling issues will take you to the water pump and coolant system. Unfortunately, leaks in the coolant system are common. Become familiar with tracking the coolant system and follow it all the way to verify there aren’t any leaks.

Problem #3: Fuel problems

Like most of the problems you’ll face with your skid steer, a problem with your fuel system is most likely caused by dirt and debris. This solution is going to be resolved by having a regular maintenance protocol around your fuel filter.


If you feel that you are working in dusty conditions more than most then you will want to change out your fuel filter more frequently than the manufacturer’s recommendation. You will also want to familiarize yourself with the overall fuel system. Understand and know where the fuel lines are and how to clean them out. Dust particles can collect in the lines as well and impede flow. Most of your costs in owning a skid steer can be severely decreased based on the amount of familiarity you have. The goal is to not have to pay someone else to diagnose your skid steer’s problems.

Problem #4: Quick Attach Coupler Issues

The next two issues are going to be resolved predominately with electrical connections. Your skid steer moves abruptly and vibrates heavily. With this connections become loose or can even become disconnected.


If your quick attach coupler isn’t working you will want to be able to trace the electrical connections to ensure they are tight. Electrical issues can be tricky and if you aren’t confident in your ability to troubleshoot it on your own, this may be a task for your dealer. You can easily spot loose connections. If you find one do what you can do tighten and see if that resolves the issue. If this gets above your pay-grade and you have to take it to the dealer, ask them to allow you to watch what they do. Or, at the end of the repair, ask them to walk you through all they did and the parts they used. 

Problem #5: Control Related Problem

Like the above problem, your controls may not work properly and it will most likely be do to some electrical problems.


Work your way through the electrical system of the controls to find any loose connections. Check circuits to see if any need to be replaced. Again, if electrical systems are not something you are confident working with, take it to the dealer and have them walk you through the repair.
