The Kubota L4760 is a high-performance tractor available on the market. A Kubota diesel 4-cylinder liquid-cooled 2.4 L engine powers this compact utility tractor, producing 49 hp rated at rpm 2700. It also has a PTO (power take-off) switch and hydraulic power. This compact tractor weighs about 2760 lbs. Hence, without any doubt you can rely on it for less engine noise and greater fuel efficiency.
Despite the excellent features, there are a few issues that users complain about. Starting problems, an engine problem, overheating, loss of power, transmission shifts hard, diesel knock, etc., are the common problem of Kubota L4760.
6 Common Problems of Kubota L4760:
Due to the heavy-duty jobs, branded tractors like Kubota are certain to have trouble no matter how work efficient they are. But do not worry, as most issues are fixable with regular maintenance and troubleshooting. Also, if you know the reasons behind the problems, it becomes easier to solve them.
So, the common problems of Kubota L4760 are given below:
1. Starting problem
It is possible that your Kubota tractor does not start because of one of the following reasons: the battery is dead, or the battery wires are corroded, and the connection to the battery is loose.
To fix the starting issue, check the battery first. If it does not have enough charge, then recharge it. Check the ires connected to it. If they are corroded, they would need replacement. And if they are loose, only tightening the wires will fix your tractor’s starting problem.
2. Engine problem
A broken spark plug, which can suffer wear and tear due to constant usage, is a common source of tractor engine difficulty. Low fuel usage, poor performance, and hard starts are signs of a damaged spark plug leading to engine problems later on.
If the spark plug is the issue, then replacing it would solve it. However, if still, the engine problem lingers, then check the other components.
If the engine cranks but will not start, check the fuel filter. Functioning outdoors might easily clog the filter as it is possible for dust and water to enter the system. So, make sure to clean the filters regularly after using the tractor. If required, replace the fuel filter.
3. Engine overheating
If the engine is overheating, check the radiator. The airflow through the radiator might be impeded in exceptionally dry and dusty conditions. Using compressed air, blow air through the radiator’s metal fins.
4. Loss of power
Usually, a tractor loses power when it is starved for fuel. Check the fuel tank to see if there is enough fuel or not. If not, refill it. However, if this is not the issue, check the fuel injector and the carbon deposits. If the fuel injector is seized or fueled with carbon-coated debris, they get stuck and create a sticky substance inside your tractor.
If the issue of a clogged injector is not fixed soon, it can lead to engine misfires and occur suddenly when you are driving the tractor. You might need professional help to get the clogged injector fixed.
5. Transmission shifts hard
Shifting gears might feel sloppy when if there is a transmission shifting issue. Also, you might experience the shift is not engaging. You can try tightening the bolts that hold the shifter in place to see if that solves the issue. If not, this can be caused by a problematic clutch. Replace the clutches, and that can solve the problem.
6. Diesel knock
Lack of oil can cause the diesel to knock. Also, clogged fuel filters and lines can be why diesel is not powering up the machine. This happens because the clog will stop the flow of gasoline to the engine. To solve this problem, you will need to disconnect the fuel line and blow compressed air into them.
Why does my Kubota tractor keep shutting off?
If your Kubota tractor starts up typically but then shuts down, you most likely have a fuel shortage. Check the fuel filter, pump, and lines, as well as the fuel lines and air filters, for fuel and airflow problems.
What are the problems with Kubota tractors?
Kubota tractor owners have experienced losing speed when operating, locking up steering functions, and part failure. There have also been reports of pitch hydraulic noise and loader drifting, in addition to the regular Kubota tractor issues.
Whether you own a Kubota L4760 or are thinking about buying the model, you should be aware of the issues you might need to deal with and prepare for them. However, it is an excellent option for your small to medium-sized lawns to do your heavy-duty work.
