Using the outer two shanks when ripping medium material is optimal for several reasons. This configuration allows for a wider area of disruption, making it easier to penetrate the material without overloading the tractor and its components. The two outer shanks create a more efficient ripping pattern, facilitating uniform depth and reducing the chances of the tractor becoming stuck or encountering resistance that could affect performance.

Additionally, this setup helps manage the load on the equipment effectively. By concentrating force and providing balance, it enhances operational efficiency, especially in medium to harder materials where a single shank might struggle to perform adequately. Utilizing the outer shanks minimizes the risk of damage to the tractor while ensuring effectiveness in breaking up the soil or material.

Other configurations, like using only one or three shanks, could lead to uneven ripping or excessive strain on the machine. Therefore, using the outer two shanks stands out as the best practice for achieving effective ripping in medium materials.
