6 John Deere 333g Problems And How to Fix Them

Like any other piece of heavy equipment, John Deere 333G also encounters several issues. And it will eventually need servicing at some point.

Problem 1. John Deere 333g Hydraulic Problems 

John Deere’s 333G trucks, especially the early models, encountered an awful hydraulic issue. 

When this happens, everything explodes because of extreme pressure. The hydraulic system is going to fill up no matter how you pedal.

Another issue was the loader’s obvious inability to rise. There remained a chance of it freezing and turning immobile. Along with that, the ‘Hydraulic Restriction’ indicator light may be seen to be blinking.


There might be two reasons working behind the hydraulic problem of John Deere 333g. Here are those. 

  • In-seat or in-bar sensors might be at fault as well. 
  • Plus, failure of hydraulic pressure sensors can create this issue. John Deere’s hydraulics is not going to work in that case. 


The solution for it is not very complex. You can do it on your own very easily.

  • To solve this problem, you need to throw out the sensors. Then, replace them with new ones. 
  • Next, you also have to clean the fuel filter. Do it by removing the filter from the gas tank. 
  • Also, you may switch out the hydraulic fuel and fill it up. Thus you can guarantee it is of high quality. 

And just like that, your issues are supposed to be resolved. 

Problem 2. John Deere 333g Fuel Filter Choking Problems 

The machine might start up but would collapse within a few moments.

The throttle might not function at all. An apparently infinite period passes after the engine is turned on, and then the engine’s maximum RPM is achieved. 

Warming the engine by operating it at low RPM may slow it down. And you might never reach the top speed.


Here are a few reasons that may lead to fuel filter joking problems. Have a look at those. 

  • The gasoline filter might be clogged up. When the gasoline collection tube is installed, algae or other particles in the tank could clog it and restrict fuel flow. 
  • There might be problems with the gasoline lines and filter, but it’s not a given. 

Now let us get to how to solve this issue. 


To solve the issue, firstly, you are gonna need to bring out the fuel nozzle. And then go ahead and blast it in the air. Then return it to that tank from your fuel water separator.

Also, inspect that your inline filter’s mesh size is not smaller than what is required. You can ensure that by corresponding to the rating of the mesh.

Problem 3. John Deere 333g Engine Problems

When an engine won’t start, inspect the fuel system because some of the most common issues originate there. 

A John Deere 333G fuel system typically consists of a tank, fuel filters, and fuel lines, all of which need to be examined separately. Because each one of these can be the cause of engine issues. 

Glow plug issues with the engine are also quite common. Glow plugs enable the entire machine to function as intended by warming the engine’s combustion chambers in a chilly environment.

This glow plugs periodically come away, which keeps the engine from getting warm.


If you don’t replace the filters as frequently as the manufacturer advises, issues could develop. Especially, if your John Deere 333G runs on diesel fuel. 

The engine’s performance may decrease if fuel cannot flow from the tank to the fuel injector. Since clogged fuel injectors are frequently to blame for inadequate fuel flow.  


To solve this issue, you need to first locate the plugs on both sides of your machine. Then, you will have to check the plugs to ensure that these have been tightly connected. 

Also, ensure that the engine’s throttle cable has been secured to the body. Untightened wires could stave off the engine from starting or operating properly on certain occasions. 

Finally, also Inspect the cord from both ends. This way, you can determine its safety.

The cables need to be connected to that throttle body. These are often located at the upper front of the motor and the accelerator.

Problem 4. John Deere 333g Control System Problems

This is another issue that John Deere 333G users encounter very frequently. 


The loader and steering joysticks of John Deere 333g machines can become unresponsive. It then leads to control system issues


If you encounter such issues, you may need to connect or tighten the connections at the steering wheel or loader.

Also, as a safety precaution, double-check the wiring which directs from the joystick to the actuators as well as the hydraulic pump. 

However, it can be that you have already tried everything else. And still, the joystick control circuit board does not seem to be working. In that case, you may require to replace the whole device.

Sometimes the controls react too slowly, and the. You need to be examining the John Deere 333G safety switches. Along with that, do not forget to double-check the connections mentioned above.

The control system is going to have ripple effects in case these safety switches fail. Each connection in the switches must be tight, or else they will not be working correctly.

Finally, Inspect the battery and look for any discharge. This is very crucial as faulty circuits could damage the control system, as well.

Problem 5. John Deere 333g Electrical Problems 

One of the most prevalent problems with the John Deere 333G is locking up. The possibility exists that the booms and parking brake will jam.

The entire gauge cluster can therefore malfunction. This can unlock the device and activate the starter.


The connections inside the cluster are presumably not particularly tight.

Another reason for this might be that the parking brake is not engaging. That is because the seat belt switch might have tripped due to the car’s jarring motion.


The connections inside the cluster are presumably not particularly tight. In that case, consider replacing the gauge cluster. 

This ignition switch here also shorts out quite a bit too. You should also update this.

The brake wire is yet another weak spot. It needs to be checked properly, and if you feel necessary, consider replacing it.

Problem 6. John Deere 333g Parking Brake Problems

The parking brake adds an additional level of complication in addition to a number of electrical problems. 

The skid loader and the brake rotor can both be disassembled using its gear. Some users claim that after releasing the parking brake, the seat belt lights continued to be “on.”


The electrical harness may become too short when the springs snap, which can jam the lock. If the solenoids are not turned off, the machine is unusable.


The solution to these brake issues are quite simple. First of all, remove the seat and safety belt. Find a broken spring with a length of between 1 and 1/2 inches in the brake system.

The brake won’t fully release or disengage if the spring is damaged.

Consider replacing the solenoids, seat switches, or seat belt switches if they are damaged or broken. The wiring harness might also need to be changed.

John Deere 333g Fuel Capacity
