BIGHAM KAM-PAC MOTOR GRADERS

The Bigham KAM-PAC motor grader is a heavy-duty road construction and maintenance machine powered by a John Deere PowerTech PSS 9.0L six-cylinder diesel engine delivering 275 net horsepower and approximately 1,029 lb-ft of peak torque with a 50% torque rise for responsive performance. Weighing between 45,195 and 55,000 pounds depending on configuration, this 29-foot-2-inch-long grader features a dual-path hydrostatic transmission with eight forward and reverse speeds, enabling fingertip armrest-mounted control of precise grading operations. The machine's 14-foot moldboard can penetrate 16.8 inches into the ground while achieving a 49,500-pound blade pull force, supported by articulation capabilities of ±22 degrees and axle oscillation of ±32 degrees for navigating challenging terrain. Equipped with a hydrostatic drive system, the grader offers selectable six-wheel drive and multiple gear ratios optimized for power delivery across various speed ranges. The 20-foot-3-inch wheelbase and 23-foot-8-inch minimum turning radius provide maneuverability on constrained job sites, while 17.5R25 tires on 14-inch rims or alternative 14.00-24 options ensure traction on diverse surfaces. Multiple wet-disc hydraulic service brakes provide reliable stopping control for the machine's substantial operating weight. Advanced features include optional dual joystick articulation controls, factory-calibrated SmartGrade integration for precision grading, and eco-mode functionality for fuel efficiency during extended operations.
