The Kubota tractor company was founded in 1890 and is known worldwide for manufacturing superior quality products. The continuous improvement of their product line has earned them the loyalty of their loyal customers.

This brand is always at the forefront of technology and design, and they provide products that reflect the latest trends and technology. Kubota offers many tractor models, including farmstead, upland field, and paddy fields.

Regeneration occurs when soot builds up in the diesel particulate filter. Depending on the engine’s load, this process can be automatic or delayed. You can continue to work with the tractor during this time.

It’s important to remember that a Kubota tractor’s regeneration process can fail at any time, so it is important to maintain it properly.

If your Kubota tractor keeps failing to regenerate, you’re not alone. Many people have experienced the same problem, and if you’re wondering how to solve this issue, we have compiled a guide to help you.

This guide will discuss why it’s happening, what causes it, and how you can prevent it from occurring again. Read on to learn more.

Troubleshooting Kubota Regeneration Problems

Regeneration problems can affect your Kubota tractor. It is important to know what this process is and how it works to avoid any problems. If you are experiencing problems, you can even take your tractor to the dealer to get it fixed. This process may be affected by various factors and a professional technician can help reset the settings to get it working again.

What is Passive Regeneration?

Many people wonder what passive regeneration is. Almost all tractors come with the passive regeneration feature, but it’s important to know what it is and when it should be performed. It takes thirty to forty minutes to regenerate, but the benefits outweigh the downsides.

For starters, passive regeneration is more effective in certain situations, such as when working in an area where soot accumulates more rapidly.

Passive regeneration is a mechanical process in a diesel engine’s exhaust system. It burns off soot on the filter when it reaches a certain percentage. When it does, the engine’s exhaust temperature reaches a higher level, forcing the switch.

This process is very effective and will save fuel and help reduce emissions. The Kubota has multiple sensors that detect when soot reaches an unsafe level.

What is Active Regeneration?

The manufacturers of Kubota tractors have devised a new technology called Active Regeneration. It works by generating higher exhaust temperatures by burning soot.

The technology is beneficial because most Kubota tractors do not exceed the speed limits of a passive regeneration. Nevertheless, you might still encounter a problem with your tractor’s regeneration.

There are many reasons behind the problems of regeneration. Some of them are:

Regeneration problems can affect the performance of a Kubota tractor. These problems can occur due to several factors. First, the engine needs time to regenerate. When the regeneration time is short, the engine may not be able to regenerate.

Also, dirty air filters and poor fuel can contribute to the problem. Having a dealer service the tractor can help you reset the settings. Moreover, the sensors must function properly for the regeneration process.

The problem with soot is that you cannot turn off the engine until every sot particle is burnt in the filter. If you want to stop soot buildup and restore the life of your engine, you have to repair the filter. If the problem persists, it may be best to get the tractor checked by a certified technician.

Otherwise, you need to drive your tractor for at least 45 minutes at a speed of 45 KPH. Let’s take a look at the reasons behind these problems:

Failure of the sensor

Failure of the sensor

The regeneration process is essential for preventing engine overheating. Kubota tractor manufacturers use an active regeneration process that burns away the soot in the diesel particulate filter.

When a Kubota tractor’s regeneration function is compromised, the tractor’s engine can malfunction. When your tractor experiences regeneration problems, it can be caused by several things. Failure of the sensor is one of the most common.

If the regeneration indicator keeps flashing, it could signal a sensor failure. The sensor problem causes the vehicle to not regenerate, resulting in engine seizures.

Clogged Filter

Clogged Filter

Several factors can cause regeneration problems in Kubota tractors. Low engine load and high RPMs speed up the soot buildup inside the machinery.

Always check the oil quality in your Kubota tractor to prevent such problems. If the regeneration indicator lights up intermittently, the filter may be clogged. In such a case, it may be necessary to replace the filter or have it cleaned.

Short Distance Drives

Short Distance Drives

Kubota reaeration problems can be caused by driving the machine for a short distance without allowing the engine to regenerate. You can either delay this process outdoors or run the machine while it regenerates.

Despite so many reasons behind the regeneration problem, we can take some steps to avoid them. Some of them are listed below:

  • You can use cleaning additives to clean your Kabuta filters. They can also be purchased from Amazon.
  • To maintain the best performance for your KUBOTA tractor, you should manually contact the KUBOTA maintenance center to remove all particles.
  • Many consumers have complained of their Kubota tractor regeneration problems. These issues can affect the fuel efficiency and performance of a tractor. To avoid these issues, you should change your filter often. If you do not regularly change the filter, it could lead to blockages and even engine seizing. In addition to replacing the filter, you should clean the rest of the system, including the DPF.
  • The most common cause of Kubota regeneration problems is low oil levels. The engine will not start the regeneration process if the level is low. To avoid this issue, top up your oil level regularly. Ensure your engine has reached an operating temperature before trying to force the regeneration.


Regeneration problems are common. When a problem occurs, you may notice higher fuel consumption and problems with surrounding components.

We have prepared a comprehensive guide about Kubota regeneration problems and hopefully by going through the steps mentioned above, you can avoid and get rid of many common regeneration problems associated with Kubota tractors.
