The motor grader employs a Hydroshift transmission with six forward and six reverse gears, achieving maximum speeds of 27 mph forward and 28 mph reverse. The front axle offers a ground clearance of 1.9 feet and oscillates 30 degrees total with a 20-degree wheel lean, supporting rough terrain adaptability. Steering articulation reaches 36 degrees with a turning radius of 34.2 feet, enhancing maneuverability in confined spaces. Standard operating weight totals approximately 23,655.7 lbs, distributed 6,613.9 lbs on the front axle and 17,041.8 lbs on the rear. Tires size 13.00-24-8 PR completes the setup, optimized for traction and stability. The max lift above ground for the circle is 17 inches, with max reach outside tires of 80.8 inches left and 78.8 inches right, facilitating versatile blade positioning during operation.
