A tractor is a farming vehicle that mechanizes agriculture-related tasks. They come in different shapes and sizes to handle different tasks, such as plowing, tillage, etc. They reduce the costs and take away all the hassle from farming.
Furthermore, they also improve the soil’s quality, making them a must-have piece of equipment for every farmer.
With that out of the way, choosing a tractor can be overwhelming, especially if you are purchasing it for the first time. With new brands joining this business and hundreds of them already established, it can be hard for you to choose your first tractor.
In this cutthroat competition, only a few companies have been able to hold their popularity, and Kubota is one of them.
Kubota is a leading company that designs and produces top-quality solutions for farming. It was established in 1890 and has been on a roll since then. It has a huge lineup of tractors and other farming equipment.
The majority of Kubota tractors feature 3-cylinders diesel engines. As the name suggests, these engines have three cylinders and are more fuel efficient than their 4-cylinder counterparts.
They ensure operation while saving your fuel and are also backed by a warranty. However, some users have stated that this engine doesn’t start sometimes.
So, why does the Kubota 3-cylinders diesel engine not start sometimes, and what to do if yours is not starting? Today, we will share some common reasons and solutions for this problem. Let’s dig out!
Kubota 3 Cylinder Diesel Won’t Start
Kubota 3-cylinder diesel engine not working? Here are some workarounds to try!
- Check Fuel Injectors & Valves
If your Kubota 3-cylinder diesel engine is not starting properly, you should start by checking the fuel system on your unit. There could be something wrong with the fuel injectors which might be causing this problem.
A fuel injector plays a key role in the combustion of your tractor’s engine as it takes fuel from the fuel pump and injects it into the intake manifold of your Kubota tractor.
There are many symptoms of failing injectors that can help you diagnose the problem, such as starting issues, poor fuel efficiency, etc.
The Kubota 3-cylinder diesel engine is known for its exceptional fuel efficiency, so if you notice that your Kubota tractor is consuming more fuel than it usually does, a faulty fuel injector could be the reason.
Furthermore, if there is strange smoke coming from the tailpipe, consider taking a look at the fuel injector of your Kubota tractor.
To check the fuel injector of your Kubota 3-cylinder diesel engine, you will first need to take it out of your engine. After that, see if it is clogged by carbon buildup. If it is dirty or clogged, get it cleaned from a workshop.
If you want to clean it at home, consider buying a fuel injector cleaner. These cleaners are usually available at superstores.
If the fuel injector of your Kubota 3-cylinder diesel engine is not clogged, it can still cause the starting problem in your Kubota 3-cylinder diesel engine. So, make sure that it is not damaged. Check its disc, return spring, and all other components and make sure they are in good condition.
If the fuel injector is not the problem, proceed to check the valves of your Kubota 3-cylinder diesel engine.
These valves are found in the cylinder head of your Kubota tractor and are responsible for controlling the flow of gases in your engine. If your engine is emitting rattling noise, its engine valves need your attention.
Having said that, there is nothing to worry about if the engine valves of your Kubota 3-cylinder diesel engine go bad. They are in a continuous state of motion, and like all mechanical components, they are also susceptible to wear and tear.
However, it is advised to repair or replace worn-out engine valves ASAP as they can cause damage to other components of your engine. Furthermore, it can also drastically affect your tractor’s fuel consumption. So, call in a trained professional and let them deal with it.
And yes, you also need to make sure that the engine valves are clean. They can get dirty or corroded over time, often leading to the starting problem in the Kubota 3-cylinder diesel engine.
This is why it is recommended to check your engine valves every now and then. If found dirty, clean them using a special cleaner and a brush.
Sometimes, the problem could be as simple as a clogged fuel filter. So, if you have not replaced the fuel filter in a long time, now might be a good time to change it.
- Replace Starter
If you’re sure that there is nothing wrong with the fuel injectors and that all the fuel valves are working properly, the problem could be with the starter. As the name tells you, a starter is a component that engages your Kubota 3-cylinder diesel engine.
Of course, if it is having some problem, the Kubota 3-cylinder diesel engine will not start.
Checking an engine starter is not an easy process. So, if you lack proper knowledge, consider reaching out to an expert. However, if you want to repair it on your own, it would be a good idea to check the user manual of your Kubota tractor. The manual will also tell you about its location.
If the starter of your Kubota 3-cylinder diesel engine has gone bad, replacing it is the only solution. The good news for you is that it is readily available across the globe and is not expensive either.
- Check Wiring Status
Faulty or damaged wiring in your Kubota tractor can also lead to the starting problem. So, you will have to check all the wires and make sure they are not damaged or burnt.
If the wires of your Kubota tractor are defective or have no voltage, you will likely have a hard time trying to start your Kubota 3-cylinder diesel engine.
It would be better to check the wires with a multimeter. A multimeter is a device that is used to check the electrical properties of an electric component. Connect its leads to the wires to determine whether the wires of your tractor are good or not.
And yes, if you are using a digital multimeter, consider selecting the beep mode. This way, you won’t have to check its reading and compare it with the recommended reading.
If they are the problem, replace them, and your Kubota 3-cylinder diesel engine will start properly. In addition to that, make sure that the connection points are clean.
There are many components that work together to keep your engine running, and if any of those components goes bad, the Kubota 3-cylinder diesel engine may not start properly.
The Bottom Line
The Kubota 3-cylinder diesel engines are a preferred option for many farmers, thanks to their excellent fuel efficiency and durability. However, some users reported that these engines do not engage sometimes. There could be many reasons for this issue, which we have discussed in this article.
If your engine has started emitting noises or consuming more fuel, check its fuel injector and valves. A defective starter and wiring can also cause this problem. Regular maintenance is recommended for your engine’s optimal performance.
