It features an 84-inch wide, 60-inch diameter smooth drum with a thickness of 1 inch, delivering a static linear load of 168 lb/in to effectively compact various soil types. Powered by a Cummins 4BT 3.9-C turbocharged diesel engine rated at 102 hp at 2200 rpm, it combines fuel efficiency and durable performance, supported by a 66.1-gallon fuel capacity. The machine offers a maximum speed of 6.3 mph and a gradeability of 57%, suitable for road building, airfield, dam, harbor, and industrial applications. The hydraulic system includes axial piston pumps with variable displacement for driving and vibration, and a gear pump for steering, ensuring precise control and maneuverability. Braking is managed by a fail-safe multidisc parking/emergency brake on the rear axle and a hydrostatic service brake for forward and reverse operation. The CA250D is built for extended use in tough environments, balancing power, weight, and operational efficiency with 80% tire wear on 23.1x26 tires. Its dimensions include an overall length of 218.51 inches and a height with ROPS of 9.69 ft, making it a versatile compactor in construction and infrastructure projects.
