Kubota is one of the most popular options that you can choose from, especially when you are looking for farming services.
Not only do they offer great products that are all aimed at helping you be able to get all your farming needs done.
While choosing between the Kubota lineup, the L3710 is a popular choice that individuals like to pick.
However, certain problems can pop up when using this tractor. The article above will list some of the most common problems and how you can fix them in detail.
Common Kubota L3710 Problems
- The Motor Does Not Turn Over
One of the most common issues you can run into while using the Kubota L3710 is that the motor won’t turn over.
If that is the case, we recommend you start by checking the recommended fuel grade.
A defective high-pressure pump can also cause an issue to the surface, which a complete replacement of the component can only fix.
- Engine Lacking Power
Another really common problem with the Kubota L3710 is issues with the engine.
It could be that there is improper fuel or insufficient or leaking valves that can all cause the engine to start malfunctioning suddenly.
On top of that, another reason for the engine to act up is if the operating temperature is too low.
If that is the case, you will have to raise the operating temperature to what it normally should be.
- Engine Is Missing
While operating the tractor, if you notice your engine starts missing, there could be certain reasons why this can suddenly pop up.
The most common reason behind the engine’s behavior is that the fuel filters are too dirty.
- Wheels Turning Too Easily
Certain users have also complained that their wheels are too easy to turn.
You should check the minimum oil rating if you notice something similar with your tractor and want to fix it. If you notice the oil levels to be low, pour high-quality oil.
Potential damage to the steering cylinder can also cause the wheels to stop working. If this is the case, a diesel engine will not start.
- Difficulty Starting the Tractor
Certain issues with the starter speed can also cause issues while trying to start the tractor. In this case, you must attempt to change or restore the starter speed.
Apart from that, there might be restrictions on the pipe. You can also try cleaning and flushing because the issue could result from the fuel filter being dirty.
If cleaning it does not help, you will probably have to replace it.
- Diesel Overheating
Having diesel overheat is another common issue that can pop up, especially when your coolant levels are too low.
If that is so, you should start by pouring liquid on the radiator up to the recommended level.
Another reason that could lead to the same issue is having the bearings are too tight, which will require adjustment.
Likewise, a defective fan belt and lack of cooling water are other reasons for your diesel’s overheating.
- Transmission Issue
The Kubota L3710 is known to have issues with its transmission, especially when equipped with a loader.
The loader puts extra strain on the drivetrain and can cause slippage and other problems while in gear. The tractor can become hard to shift or refuse to stay in gear.
A tested fix for this issue is to replace the transmission oil with a higher-viscosity oil, such as 75W-90.
It’s also important to ensure the transmission filter is replaced regularly, as it can become clogged and cause further slippage issues.
- Hydraulic Problems
The hydraulic system of the Kubota L3710 is prone to failure over time. The most common problems are related to leaks in the system, which can occur due to worn-out O-rings or seals.
These issues can cause the tractor to lose power and eventually shut down altogether if left unchecked.
It’s important to inspect the hydraulic hoses for any signs of wear or damage and repair them immediately if any are found.
It’s also important to ensure the hydraulic fluid is changed regularly, as it can become contaminated and cause further problems.
- Inadequate Cooling System
The Kubota L3710 has an inadequate cooling system that can lead to overheating issues.
The tractor has a radiator, but more than its size is needed to handle the amount of heat generated by the engine.
This can lead to the tractor shutting down in hot weather or failing due to a blown head gasket.
To prevent this issue, it’s important to upgrade the radiator to one that is bigger and can cool more efficiently.
- Spark Plug Problems
Another common issue with the Kubota L3710 is that the spark plugs can fumble over time due to debris buildup.
The plugs can become clogged and fail to ignite the fuel, resulting in a hard or no start. To solve this problem, clean or replace the spark plugs every few months to ensure they are working correctly.
It’s also important to check the gap between the spark plug electrodes, as they can become misaligned over time and cause further problems.
- Fuel System Issues
The fuel system of the Kubota L3710 is susceptible to clogging due to debris buildup in the fuel lines.
This can lead to the tractor stalling or not starting at all. It’s important to regularly clean the fuel filter, as this is one of the most common causes of fuel system problems.
Additionally, it’s important to ensure the fuel lines are clear and in good condition, as any damage here can also cause clogging or other fuel-related issues.
- Faulty Electrical System
The electrical system of the Kubota L3710 is known to have problems, mainly due to its age and lack of modern components.
The wiring harnesses can become brittle over time due to exposure to heat and vibration, leading to shorts or open circuits that can cause the tractor to shut down or fail to start.
Inspecting the wiring harnesses regularly and repairing any damaged wires immediately is important.
It is important to ensure all connections are tight and free of corrosion, as this can cause electrical problems.
- The engine won’t stop running.
At times the Kubota L3710 engine won’t stop running. A faulty electrical switch, damaged wiring, or a defective fuel pump relay can cause this.
If your L3710’s engine doesn’t shut off, you should inspect these components and make sure they are in working order. If they are not, you should replace them.
- Difficult to start
Kubota L3710 is, at times, difficult to start up. This can stem from various issues, including a clogged fuel filter, bad spark plugs or wires, and a weak battery.
If your L3710 has trouble starting up, you should inspect these components and replace or clean them if necessary.
- Grinding sound
If you notice a grinding sound coming from your L3710, it could indicate that the engine’s valves are out of adjustment or the timing belt is misaligned.
To fix this problem, consult your manual and adjust the valves as needed or bring in a professional to realign the timing belt.
A common reason for excess vibration is a worn drive belt or misaligned pulleys. Inspect the belts and pulleys regularly, as they will wear over time.
If you find any signs of wear, replace them as soon as possible to prevent long-term damage.
- Excessive Vibration
Another issue that may arise with the Kubota L3710 is excessive vibration. Several factors, such as damaged or worn engine mounts, faulty bearings, or loose components, could cause this.
If you notice abnormal shaking while driving your L3710, you should inspect its components and identify the cause. Once identified, you can take the necessary steps to fix this problem.
- No forward/Reverse gear
If your Kubota L3710 has difficulty shifting forward or reverse, it could indicate a failed clutch assembly.
To fix this issue, you should bring a professional to inspect and replace the worn or damaged parts.
You may need to have the transmission fluid flushed and replaced if there is any visible dirt or debris.
You can adjust the clutch cable tension. With these steps, your L3710 should be able to shift forward and reverse again.
- Poor fuel economy
If your Kubota L3710 is experiencing poor fuel economy, it could be due to a faulty air filter or a clogged fuel injector.
It is important to regularly inspect and replace your air filter, as it can get clogged with dirt and debris.
You should consider cleaning or replacing the fuel injector if needed. These steps can help improve the efficiency of your L3710 engine.
The Bottom Line:
Even though the Kubota L3710 is a great tractor, certain problems can suddenly pop up while using the tractor.
We have listed some of the most effective solutions in the above article to fix these problems. All you have to do is to give all these instructions a thorough read.
