how to change a hydraulic hose on a plow


Understanding the Importance of a Reliable Hydraulic Hose on a Plow

A hydraulic hose plays a critical role in the functioning of a plow. It allows the transfer of hydraulic fluid, which provides power to various components of the plow, such as the blade or lift mechanism. Over time, hydraulic hoses can deteriorate due to wear and tear, resulting in leaks or decreased performance. Knowing how to change a hydraulic hose on a plow is essential for maintaining its efficiency and prolonging its lifespan. In this article, we will guide you through the process step-by-step, ensuring a successful hose replacement.

Gathering the Necessary Tools and Materials

Before proceeding with changing the hydraulic hose on your plow, make sure you have all the required tools and materials at hand. These typically include a wrench, pliers, a tubing cutter, hydraulic oil, hose clamps, and a replacement hydraulic hose of the appropriate size. Confirm the specifications of the hose required for your specific plow model, as it can vary based on the manufacturer and plow type.

Evaluating the Plow and Identifying the Problematic Hose

First and foremost, carefully examine your plow to locate the faulty hydraulic hose. Inspect the hose for any visible signs of wear, such as cracks, abrasions, or leaking fluid. It is crucial to identify the problematic hose accurately to ensure you are replacing the correct one. Take note of the hose's length, connectors, and fittings to find an appropriate replacement.

Safely Shutting Down and Removing the Old Hydraulic Hose

Before starting the hose replacement, ensure that the plow is shut down and all hydraulic functions are fully retracted. This prevents accidental movement or hydraulic fluid spraying, ensuring your safety. Once the plow is secured, carefully loosen the fittings connecting the faulty hose to the plow's hydraulic system using the appropriate wrench or pliers. Remember to place a container beneath the hose you are removing to catch any residual hydraulic fluid.

After loosening the connectors, carefully remove the old hydraulic hose from the plow. Pay attention to any fittings or clamps connected along the hose's length. If necessary, cut the hose into smaller sections for easier removal using a tubing cutter.

Installing the New Hydraulic Hose and Ensuring Proper Connection

Now that the old hose is removed, it's time to install the new hydraulic hose in its place. Begin by applying a thin layer of hydraulic oil on the fittings' threads or O-rings to ensure a smooth connection and prevent leaks. Carefully insert one end of the hose into the corresponding connector, ensuring a snug fit. Use hose clamps to secure the hose in place, ensuring proper alignment with the plow's hydraulic system.

Repeat this process for the opposite end of the plow's hydraulic system, ensuring a secure connection. Once everything is properly installed, double-check all connections and fittings to confirm they are tight and leak-free.


Regular maintenance and timely replacement of hydraulic hoses are essential for ensuring the smooth operation of a plow. By following the steps outlined in this article, you can confidently change a hydraulic hose on a plow, avoiding potential issues caused by leaks or damaged hoses. Remember to prioritize safety, use the required tools, and carefully select the appropriate replacement hose for your plow model. With proper care, your plow will continue efficiently clearing snow and maintaining optimal performance.
