  • Starter not working
  • Transmission making loud noises
  • Skid steer vibrating on ignition
  • Engine stalling etc.

To be honest, these issues are very common for your John Deere 325g skid steer and you might have to face these issues very frequently.

But if you are willing to pay attention, you can get some of the major issues solved all by yourself. 

John Deere 325g Skid Steer Problems and Solutions

1. Engine Overheating

John Deere 325 g has a frequent overheating issue that sadly increases as it gets old.

You see, with time the radiator is clogged up with dirt particles and doesn’t pass through enough cool air. As a result, after a couple of hours of operation, the track loader starts to heat up very much.

But it’s really important to keep the machine cool because otherwise the engine performance will deteriorate gradually and your truck can even be under high risk of catching fire.


First off, you have to clean the radiator. You can also clean the reversible fan frequently if your track loader faces dusty conditions very often. If they are stacked together then separate them first before cleaning.

Sometimes many sticky substances can build up inside the radiator and just washing them with water does not solve the problem.

In this case, you can use cleaning products to wash out the stubborn particles that won’t wash with just plain water.

If cleaning doesn’t resolve the overheating issue then check if the water pump is functioning enough to cool the engine.

If there is any problem with the head gasket then under heavy loading conditions the engine will easily get overheated. 

If there is anything wrong with the radiator parts of the fan then you have to take it out, disassemble the parts and repair them.

If it doesn’t work out you need to get a new one because we can’t let the engine overheat for the sake of safely operating the truck. 

Next, up make sure there is no leak in the cooling system. If you find any coolant product leaking through the system you have to stop the leakage at once.

Also, If your track loader keeps up the pressure overnight then the head gasket issue is most likely the problem.

After cleaning the cooling system if the engine keeps overheating then your head gasket is the thing that needs to be changed.

Sometimes the engine can overheat if the engine oil level is not enough. In this case, make sure you check the engine oil level frequently and keep the oil level up to a certain mark.

And last but not the least, you have to check the thermostat. Sometimes it malfunctions so you have to take it out and test it in a hot water plate or stove. If it’s the culprit you can easily get a new one.

2. Hydraulic System Problems

The main problem of John Deere 325 g is, it overheats and causes the whole engine to stop running. When there is any issue with the hydraulic pump the engine will make loud noises.

Also if there are any leaks in the valves of the hydraulic system then the engine will have problems while running. 

Sometimes there can be damaged hoses of fittings in the hydraulic system causing complete failure of any field operation. To avoid any safety hazards you have to address these hydraulic problems as soon as possible.

When there are any hydraulic issues the fluid temperature will rise above 180°F (82°C) so you can definitely check the fluid temperature to be sure what’s the issue before starting to work.


When your track loader isn’t functioning properly the first thing you need to check is the hydraulic fluid level of your engine.

You have to keep the fluid-filled up in the tank up to a certain level as per the manufacturer’s requirement.

Then you have to check the hydraulic filters because if they are clogged the hydraulic fluid doesn’t flow efficiently and reduces the productivity of the engine. You can either get the filters cleaned or you can replace the fuel filter.

If the problem still doesn’t seem to go away then you have to check the hydraulic pump. You can disassemble the pump and see what is wrong with it. 

Then you have to change the damaged or defective parts of your pump and reassemble the whole pump and connect it back to the engine.

Or if you don’t wanna go through this trouble then you can replace the whole hydraulic pump with John Deere’s specification.

3. Fuel Problems

If there are any fuel-related issues in your John Deere engine, you have to separately inspect its fuel system. The fuel tank fuel line and fuel filter have to be separately inspected.

Fuel filters can get clogged with time and this will lower the fuel circulation in the system. Even the engine won’t start if the filter is clogged.

As the fuel filter helps to keep the dirt out from the engine, it’s very vital they keep functioning all the time. Otherwise, the engine will face greater damage in the future.


Fuel filters usually need frequent replacements because they get dirty all the time. The best thing you can do is keep a spare set of filters for your tractor so that you can replace them whenever necessary.

Next thing you have to check is the fuel line and see if it’s blocked. If there is any blockage then you have to clean out the dirt to clear the path. Also, always keep your fuel tank clean

Besides, make sure you always keep your DEF tank clean. Moreover, you can also check the fuel line from the tank and see whether it’s blocked or not. If it’s blocked then remove the debris and clear the fuel line.

4. Control Related Problem 

Sometimes the loader and the joystick of john deere 325 g can have problems controlling the engine.

Even the loose connections with the steering can also create problems in your tractor while starting. It will also make the engine stall and make it stop.

When the joystick isn’t functioning properly it won’t raise or lower the loader and as a result, it will not get any work done.


So first, you have to make sure all the connections on the control circuit board are tightly made. Check all the wiring and see if there’s any damage that is causing a poor connection.

You can repair the damaged parts with scotch tape and if the cables are too worn out then replace all of them just to be safe.

If still the problem continues, calibrate the joystick by lowering the safety bar and pushing the right joystick as far as it goes. Then you have to hold it there for a moment.

Now, you have to start the ignition into RUN position and press the loader button. Meanwhile, let the joystick go slowly from your holding.

The calibration should be done in this way. But if you are having difficulty in calibrating, ask a nearby John Deere expert mechanic. 

If the problem is with the joystick not the wire connections then you have to get a new one according to John Deere’s engine’s specification.

5. Quick Attach Coupler Issues

Sometimes the newly bought John Deere 325 g can have problems with the quick attach coupler. It will be unresponsive when the button is pressed. If the coupling fails, it will not allow the transfer of energy further. 

Since it helps to connect and disconnect fluid lines, the failure of quick attach coupler will lead to uneven loading and vibration of the engine and cause massive damage. 


First off you have to check if all the wire connections and connector pins of the boom to the linear actuator are correctly done.

Sometimes the connections get loose automatically and need to be tightened. Also, they can be corroded or damaged. 

So inspect them and repair the damaged parts with thick tapes. If the connector pins are too corroded then it’s best to get some new ones. Also, make sure the connector pin at the back of the boom is plugged in properly.

Sometimes mice and rodents eat chunks out of the wires. So you can dip some cotton balls in mint oil and put them around your skid steer. This will help to keep the mice away. 

And don’t forget to use traps, repellents, and baits around your skid steer to get the rodent population under control.

Also, check if the actuator for quick attach is functioning properly. If not, replace it with a new one.

If this isn’t the issue then check all of the fuses on the fuse panel and make sure there are no failed or shorted fuses inside the panel.

Also, there is an inline fuse below the starter that helps to supply power to the switched portion of the relays. 

For Checking these you can use a voltage tester and probe the top metal parts of each fuse while running the ignition switch. You have to replace the fuses that have power only on one side of the tester.

But be sure to replace one at a time with a suitably rated fuse because if the rating doesn’t match the specification the engine will again have the same problem.  

However, if you are confused about any of these fixes and find yourself wondering how to do them, you should call John Deere’s expert mechanic instead of experimenting with the track loader.
