Troubleshooting Kubota M5-111 DEF Problems
Below are some common problems associated with the Kubota M5-111 DEF tractor.
- Replace The Current DEF With a New One
Diesel exhaust fluid, commonly known as DEF, is a mixture of deionized water and urea used in modern diesel engines to reduce air pollution. It is critical to a diesel engine as it improves your engine’s fuel efficiency. In addition, it ensures your engine’s safety and increases its power.
Like most modern diesel engines, the Kubota M5-111 DEF tractor also uses diesel exhaust fluid. It is recommended to replace this fluid now and then, or else you will start facing problems.
If your engine is running low on DEF, you will notice a significant drop in its power. And if you keep ignoring it, your Kubota M5-111 DEF tractor may even cease to work. So, keep an eye on its level and consider refilling it when needed.
Be mindful of putting the diesel exhaust fluid in the right tank. If you accidentally add it to the fuel tank, do not start your tractor. Even if you do, it will automatically shut down after a while and cause additional problems. Call a professional right away to avoid any issues.
When purchasing the diesel exhaust fluid, make sure to buy the best quality. Consider buying from a reputed dealer, and do not forget to read the customer reviews before purchasing it.
- Faulty Sensor
Many users have complained about faulty sensors in the Kubota M5-111 DEF tractor. This tractor uses sensors to alert the users about any alarming situation. So, the sensors must be in good working condition to ensure your safety.
Consider reading the owner manual to locate the sensors. If they are damaged, you may need to replace your entire system. Consider hiring a mechanic to get it checked. They will inspect your tractor and do what needs to be done.
This may cost you a few bucks, but it will surely give you peace of mind. And yes, check to see if your Kubota M5-111 DEF tractor is in the warranty period. If it is, you may get it replaced while paying the least out of your pocket.
- DEF Problem in Winter
This problem is not specific to the Kubota M5-111 DEF tractor only. If you own a tractor and live in a cold area, you’d know that it freezes in lower temperatures as it mainly consists of water.
Whether you store it in a container or put it into your tractor, it may freeze if the temperature drops below 12 degrees Fahrenheit.
The diesel exhaust fluid tends to expand when frozen, and if you have completely filled your tank, it may cause damage to your DEF tank. It is recommended to keep the tank less than full during cold periods.
And yes, if it has frozen, do not add any liquid or other additives to melt it. It may cause additional damage to your Kubota M5-111 DEF tractor.
There can be many solutions to avoid this problem, but the most effective is to install a DEF system that will create a heating effect so that the DEF does not freeze. Apart from that, consider parking your tractor in an insulated garage.
- Location of DEF Tank
It may sound weird, but the DEF tank is not placed correctly in the Kubota M5-111 DEF tractor. Kubota has manufactured dozens of well-engineered tractors and earned its name in the industry. Still, the location of DEF tanks in this particular model has disappointed the users big time.
While using the Kubota M5-111 DEF tractor, many users reported that it produces heat which damages the sensors. The only solution to alleviate this problem is to install a kit of insulation around your DEF tank. However, it is pertinent to mention that it won’t resolve the issue completely.
- Contact Customer Support
If your Kubota M5-111 DEF tractor is not working smoothly, and you are not able to identify the reason, it would be best to contact customer support as soon as possible. They might be able to help you with troubleshooting the issue.
However, it is recommended to try these fixes mentioned above first. If none of them seems helpful, reach out to customer care service by Kubota.
