Kubota L3901 Problems

Here is the list of problems Kubota L3901 often suffers from.

  • The tractor doesn’t start at all
  •  Electrical  system malfunctioning
  • Overheating of the engine
  • The steering system is not working properly
  •  Bad hydraulic usage
  • The clutch is rigid and shifts hard in reverse

Below, we will explain these problems one after the other and provide practical solutions on how to fix them.

1. The Tractor Doesn’t Start At All

On first thought, this might seem like a very hectic component failure, but put yourself together. It’s relatively easy to solve.

The Kubota L3901 not starting is usually caused by a drained battery, cold weather, or simply a lack of fuel.

Check for adequate fuel; if the fuel level is low, top it up to the required gauge.

You shouldn’t let your gas tank empty or use too old fuel.

If the tractor has been idle for many months, discarding the old fuel and replacing it with the new one might be wise.

Then the next thing to shake is the battery. Make sure it has enough charge to power your machine. Once again, this is important if the machine has been idle for a long time.

When the battery seems to die very fast after charging, It may indicate that it is faulty and needs replacement.

You should also verify that all the wires and connection points connecting the battery to the tractor are secure.

Check for damaged wires and corrosion and replace them accordingly.

Finally, it may be due to the weather, as freezing weather may prevent the engine from starting.

Give the engine time to warm up; if you can start it, idle it for about 5 to 15 minutes before proceeding to your work so it doesn’t shut down mid-job.

2. Electrical System Malfunctioning

Your tractor’s battery might cause this malfunction to be extremely low or near dead, or electrical connections may be corroded or loosed.

So when you experience an electrical malfunction, check the battery and ensure it’s fully charged or replace it if it is dead.

Also, check electrical wire connections and tighten them if any are loose.

In as much as it is an electrical malfunction, you should also check your fuel filters and clean them if it is blocked or dirty cause this could also be a problem to the malfunctioning of the tractor.

3. Overheating Of The Engine

 Overheating the engine can deter several potential issues, from reducing performance and efficiency to reducing component life or damaging the tractor’s engine.

The main reason for this issue is a fault within the cooling system; however, misaligned gearing or incorrect adjustment of belts may also contribute to this problem.

You can reduce your tractor’s load and working speed so you don’t cause excess harm to the machine.

Check the cooling system, belt, and gearing thoroughly and fix any issues, so the engine doesn’t overheat again.

4. The Steering System Is Not Working Properly

This problem is insignificant or commonly occurs with your tractor, but you might experience this.

If you face this problem, you might be unable to operate or use your tractor’s steering freely and easily.

It might drain your tractor’s practical working prowess down, which you might never want to happen.

It usually happens because of the air present in the hydraulic system.

Another factor could be deficient oiling in the tank of your tractor or, lastly, the issues with the cylinders of your steering.

For the issue of air in the hydraulic system, it is recommended to remove the air from the system and check if it works for you.

It is also essential to fill up the oil tank for the oil issue, and your issue will be resolved quickly.

And with the problem of your steering cylinders, you must change it with a new one as it is the only option you can do to cure this problem and have smooth steering functioning. 

5. Bad Hydraulic Usage

When your tractor’s hydraulic system is scorching, it could be that the wrong hydraulic type has been used.

Check the oil, change and fill it up with good hydraulic oil.

There could also be air in the hydraulic system, as this is a common problem when there is a leakage in the valve.

So you should check for leakage and change the valve if it is terrible.

Aside from bad hydraulic usage, insufficient hydraulic fluid could also be a problem.

Make sure you add oil to the required level, and in situations where the oil filter is clogged up, you will need to clean or change the filter.

6. The clutch Is Tough And Shifts Hard In Reverse

If the clutch of your tractor feels harder than usual, particularly while trying to reverse, this may indicate an issue with the transmission shift.

It’s because of a faulty or loose connection.

When you experience this problem, the first thing to check is the clutch, which may be faulty and need a repair or replacement.

You should also check the connections and repair any loosed or damaged wires.
