JOHN DEERE 450J MOTOR GRADERS

The 2016 John Deere 450J is a versatile motor grader engineered for demanding grading and road maintenance applications. This machine features a powerful engine producing 185 to 205 horsepower with 629 cubic inches of displacement, delivering robust performance across varying terrain and workloads. The grader measures approximately 28.58 to 33 feet in overall length with an 8.08 to 8.1-foot width over tires and stands 10.25 to 10.3 feet tall to the cab roof, providing operators with excellent visibility and control. The operational weight ranges from 32,357 to 36,000 pounds under standard conditions, with maximum operating weight reaching up to 46,800 pounds for demanding applications. The articulated frame design incorporates an 18 to 20-degree steering articulation angle and achieves a tight 24.3 to 24.6-foot turning radius, enhancing maneuverability in confined spaces. The moldboard spans 12 to 14 feet in width with a 24-inch height and 0.87 to 1-inch thickness, providing 28.1 inches of maximum cutting depth with 42,184 pounds of blade pull at maximum weight. The hydraulic system utilizes an axial piston pump delivering 54.4 gallons per minute at 3,500 psi relief pressure, ensuring responsive control of all grading functions. Performance capabilities include forward speeds up to 25.5 to 27.4 mph and reverse speeds of approximately 20.2 mph. The 105-gallon fuel capacity combined with efficient engine management supports extended operational periods, while comprehensive fluid capacities—including 18 to 20 gallons hydraulic fluid and 10 gallons cooling system capacity—facilitate reliable long-term operation in diverse grading environments.
