Kubota L3901 Problems – How To Fix?

If you are a big driver, certain parts of the car may bother you. As the ride gets older, trouble can also occur. Today, I will talk about some of the most common problems with Kubota L3901 problems and how to fix them.

which are as follows:

  • Steering Problems
  • Engine Overheats
  • PTO Problems
  • Regeneration Problems
  • Shuts down unexpectedly
  • Radiator prescreens cannot be removed
  • Too small an area for the operator

(1) Problem 1: Kubota L3901 Steering Problems

If your tractor feels harder to steer than usual, that’s a red flag. This is a sign that there is a problem with the steering.

Power steering systems often have trouble with leaks. If the power steering goes out, the steering will not work. If something breaks a hydraulic pipe, this can happen.

How To Fix?

If the steering on your Kubota L3901 isn’t working right, you should get all the air out of the hydraulic system. You can also check Kubota L3901’s attachments if this doesn’t work.

If the oil tank is low, filling it up should fix the problem. Lastly, you need to replace your steering cylinders if they are broken.

(2) Problem 2: Engine Overheats

Several owners have said that the engine on their Kubota L3901 gets too hot.

Most of the time, the engine could overheat because the radiator isn’t getting enough air. Remember that when dust or other debris from the outside gets into the radiator, it slows down the airflow by blocking the way.

So, the engine is running to get too hot, and as time goes on, the heat gets too much to handle, which could cause one’s engine to shut off suddenly.

How To Fix?

The problem is easy to fix, though. All you must do is properly clean the radiator fins of any debris or dust that is already there. You can even blow them out with an air compressor.

(3) Problem 3: Kubota L3901 PTO Problems

If your tractor doesn’t move when the PTO is turned on, that means the PTO on your Kubota L3901 is broken. There are many reasons why you might have trouble with PTO.

This could happen if the bush porker shuts down without power being linked to the PTO. If this occurs, the PTO might need to be fixed.

How To Fix?

When you press the clutch, the car stops moving, so check the condition of the clutch first. If the clutch is broken, fix it or get a new one.

Control valves throughout PTOs can also cause trouble because of floating points. If the PTO’s control valve isn’t working right, you could do a test method to see if it is working correctly.

You may notice an RPM shift if your throttle valve seal has broken. If this happens, the valve on your Kubota L3901 needs to be changed.

(4) Problem 4: Kubota L3901 Regeneration Problems

Something is wrong if the regeneration light on your Kubota L3901 keeps flashing. This tractor must be refueled every hour, which is a huge problem.

And if you don’t do it, it won’t work right and will make too much heat, which is bad for the area around it.

How To Fix?

You have to raise the RPM until the light indicator stops flashing or until you figure out what’s wrong with the regeneration. You can also allow this same tractor to run in the therapeutic method for 15 minutes straight.

After that, the lights must stop flashing. If this doesn’t fix the problem, you can talk to the dealer or the company that made the car.

(5) Problem 5: Shuts down unexpectedly

If one’s tractor starts up fine but stops running for no reason, there could be an issue with the fuel supply. This is a problem that a lot of tractors have. A tractor usually won’t start because the fuel filter is clogged, broken, or out of gas.

How To Fix?

Follow the directions in the manual to fill it out. This will resolve the issue of running out of gas. If that’s not the problem, users can sometimes take out the fuel injector to see if it’s still working or if dirt or other debris has clogged it up.

The fuel filter should be cleaned regularly, as suggested. If debris gets stuck in filters, it can damage them so much that they can’t be fixed. In this case, the fuel filter might need to be changed.

(6) Problem 6: Radiator prescreens cannot be removed

Small particles don’t get stuck in radiators because of prescreens. But if the radiator fan is broken or not working, it is hard to remove the radiator prescreen and pull out the fan to clean it.

This is a mistake that Kubota L3901 tractor makes by default. So, you can talk about this problem, but there needs to be a better way to fix it.

(7) Problem 7: Too small an area for the operator

A tractor needs a driver to move it around. And yet Kubota L3901 is difficult because they keep their users in a very crowded area.

If you are less than 6 feet tall, it won’t be a problem. But after that, it will become a problem, but there won’t be much that can be done to fix it.

Kubota l3901 Electrical problems

This is a big problem that could affect many different parts of the tractor.

If the tractor doesn’t start, it could be because of a problem with a spark plug. This makes a small amount of electricity that lights the fuel on fire and starts the combustion process.

If dirt or dust gets stuck in the spark plug, it won’t be able to make a spark, and the tractor won’t start.

These are easy to replace and don’t cost much. You can do it yourself without the help of a Kubota dealer. It would help if you moved both edges of the spark plug to get it out of the engine so you can put in a new one.

Engine Abruptly Shuts Down After Starting

This is a problem that most Kubota tractor designs, including L3901, have.

Several owners say that the tractor starts up fine, but the engine shuts off suddenly and without warning in the center of their work.

A tractor engine usually shuts off abruptly in the middle of its work because it is out of fuel or because an internal part like the fuel pumps, air filter, fuel lines, and air filters fails.

How To Fix?

Most of the time, it’s because there needs to be more fuel in the tank, so check the fuel level in your tractor’s tank and fill it up if necessary.

If your tractor isn’t running out of gas, you should check to see if the fuel pumps, filters, and lines are working right or if any of them are clogged or broken. If there are any broken or clogged parts over there, you should replace them.

Also, examine the air filters to see if they are clogged and replace them if they are.

Sometimes Engine Does Not Crank

Even though it’s a common problem for tractors and mowers to have engines that won’t start or take too long to start, it’s still annoying when it happens.

Most owners say that if they take care of and maintain the engine of their L3901 tractor, it works well most of the time. However, sometimes, the engine starts acting on its own and won’t crank.

This error often happens when your tractor’s battery is dead or when the rechargeable batteries cables have a problem, like a loose connection or a lot of dirt and corrosion.

How To Fix?

The problem is easy to fix, though. If your car is hard to start, you must check the condition of the battery and the battery cables as soon as you notice it.

If the battery is broken or dead, you should replace it immediately, and if one of the cables seems loose at the connection, you should tighten it.

Also, if dirt and corrosion are to blame, use a professional cleaning fluid to clean them thoroughly.

While there, remember to use an Ohm measuring device to ensure your tractor’s safety switches are reading the right voltage.
