How to Change a Hydraulic Hose on a Kubota Tractor


Maintaining your Kubota tractor is crucial for its smooth operation and longevity. One of the essential components of your Kubota tractor's hydraulic system is the hydraulic hose. Over time, these hoses can wear out, develop leaks, or become damaged, requiring replacement. Knowing how to change a hydraulic hose on your Kubota tractor can save you time and money. In this article, we will guide you through the step-by-step process, ensuring a hassle-free hose replacement.

1. Assessing the Hydraulic Hose:

Before diving into the replacement process, it is vital to assess the condition of the hydraulic hose thoroughly. Inspect the hoses for any visible signs of damage, such as cuts, bulges, cracks, or leaks. Pay close attention to the fittings, as any corrosion or damage can affect the hose's performance. By assessing the hose, you can determine whether replacement is necessary or if a simple repair might suffice.

2. Gathering the Necessary Tools and Equipment:

To replace the hydraulic hose on your Kubota tractor, gather the following tools and equipment:

- Safety goggles

- Safety gloves

- Wrench or pliers

- Bucket or oil drain pan

- Replacement hydraulic hose

- Thread sealant

Having these tools and equipment handy will ensure a smooth and efficient replacement process.

3. Preparing the Tractor:

Before starting the replacement process, it is crucial to prepare your Kubota tractor for the task. Turn off the engine and allow it to cool down completely. Relieve the pressure from the hydraulic system by engaging the control lever multiple times. This step is essential for your safety and to prevent any accidental releases of hydraulic pressure.

4. Removing the Old Hydraulic Hose:

To begin, locate the hydraulic hose you need to replace. Use a wrench or pliers to loosen and remove the fittings at both ends of the hose. Place a bucket or oil drain pan under the hose to catch any hydraulic fluid that may spill during removal. Once the fittings are detached, carefully pull the old hydraulic hose out of its connections. Take note of the hose's routing and length, as this will help when installing the new hose.

5. Installing the New Hydraulic Hose:

Before installing the new hydraulic hose, apply a thin layer of thread sealant to the threads of the fittings. This will prevent hydraulic fluid from leaking out. Carefully route the new hose following the same path as the old one. Ensure that the hose is not kinked or twisted, as this can impair its performance. Attach the fittings at both ends of the new hose, ensuring they are properly tightened but not overly tightened.

6. Testing for Leaks:

Once the new hydraulic hose is installed, it's crucial to check for any potential leaks. Start the Kubota tractor and allow the hydraulic system to circulate fluid. Carefully observe the new hose and its connections for any signs of leakage or seepage. If you notice any leaks, immediately turn off the tractor and tighten the fittings accordingly. Repeat the testing process until you are confident that the hose is leak-free.


Congratulations! You have successfully changed the hydraulic hose on your Kubota tractor. Regularly monitoring the condition of your tractor's hydraulic hoses and promptly replacing any damaged ones will ensure the optimal performance and longevity of your equipment. By following the step-by-step process outlined in this article, you'll be well-prepared to tackle any hydraulic hose replacements on your Kubota tractor. Remember, safety is paramount throughout the process, so always wear goggles and gloves, and exercise caution while working with hydraulic systems.
