It features tandem smooth steel drums with a diameter of 20 inches (1.7 ft front and rear), each 28 inches wide, producing a high centrifugal force of 2,665 lbs for effective soil compaction. The roller operates in static mode with a nominal amplitude of 0.1 inch at high settings. Powered by an 18 hp (13 kW) engine, it ensures reliable performance with a max speed of 6 mph (10 kph). The Mauldin 4000 has a fuel capacity of 5 gallons and an 8-gallon hydraulic fluid reservoir, enabling extended operation. Its overall length is approximately 7 feet, width is 3.3 feet, and it has a wheelbase of 4.8 feet, allowing accessibility in confined workspaces. The machine's ground clearance is 0.8 inches, and the height to the top of the cab is 5 feet, providing a low profile suitable for various construction and paving projects. With an operating weight of 4,000 lbs, it balances sufficient weight and maneuverability for smooth, even compaction on asphalt, granular, or other compactable materials. The hydrostatic drive system enhances control and operator comfort during use. This roller is ideal for contractors seeking a dependable, easy-to-operate compactor with precise control and consistent compaction quality in small-to-medium scale applications.
