HUBER 883 MOTOR GRADERS

Technical Description

The 1990 Huber 883 Motor Grader is powered by a Komatsu 6V653 engine, a robust 6-cylinder diesel known for reliability and performance in heavy-duty applications. This engine delivers between 165 hp and 218 hp, depending on the specific configuration, operating at 2,100 rpm. The grader’s operating weight ranges from approximately 27,624 lb to 41,667 lb, varying with model and setup. The moldboard width typically spans 12.1 to 14 feet, with a blade length of about 14 feet, providing substantial grading capacity. The transmission features dual-mode operation, offering selectable eco and power modes, and incorporates a torque converter with stall prevention technology for improved efficiency and control. The hydraulic system is a closed-center load-sensing design, enabling simultaneous operation of multiple circuits independent of engine speed. Additional features include blade lift cylinders with impact absorption, an air suspension operator seat for comfort, a rearview monitor system for enhanced visibility, and a hydraulic cooling fan with variable speed control based on engine temperature and load. The moldboard offers side shift capability, with maximum shoulder reach dependent on model and attachments. This configuration ensures high productivity, durability, and operator comfort, making the Huber 883 with Komatsu 6V653 engine well-suited for demanding grading tasks.
