Technical Description

The John Deere 672A is a robust motor grader powered by a turbocharged 6-cylinder engine producing 125 horsepower and 372 lb-ft of torque, delivering reliable performance for road maintenance and construction grading applications. Measuring 27.3 feet in overall length with a 7.9-foot width over tires and weighing approximately 27,500 pounds in standard operating configuration, this machine offers excellent balance and maneuverability on jobsites. The 12-foot moldboard features a 58-inch diameter circle with 360-degree rotation capability, 16.2 inches of maximum lift, and reaches up to 87.5 inches outside the left tire, enabling precise grading and contouring in various soil conditions. The articulated frame steering system provides a 22.6-foot turning radius with 25-degree articulation angle for superior operator control. Equipped with an 8-speed forward and 4-speed reverse power-shift transmission, the 672A achieves maximum forward speeds of 23.9 mph and reverse speeds of 7.6 mph. The hydraulic system utilizes a closed-center variable displacement pump delivering 37.6 gallons per minute, ensuring smooth operation of all blade functions including lift, shift, and circle rotation. Standard features include dual-lever hydraulic blade control with float position, all-wheel drive capability, and a pressurized lubrication system with full-flow filtration. The oscillating front axle accommodates 30 degrees total oscillation with 20-degree wheel lean capability, maintaining consistent ground contact across uneven terrain. With a 60-gallon fuel capacity and comprehensive hydraulic system supporting reliable performance, the 672A represents proven engineering for demanding grading operations.
