Technical Description
The John Deere 672D Motor Grader is a robust, high-performance machine engineered for demanding grading applications. Powered by a turbocharged, air-to-air aftercooled John Deere 6068H engine with 6 cylinders and 414 cu in displacement, it delivers 185 hp at 2,000 rpm and up to 625 lb-ft of torque at 1,000 rpm, ensuring strong low-rpm pull-through power. The direct-drive Powershift transmission offers 8 forward and 8 reverse gears, with a maximum speed of 24.9 mph in both directions. The hydraulic system features a variable-displacement piston pump with 54.7 gpm flow and a 2,750 psi relief valve, supporting precise blade control. The 360-degree rotating circle provides a blade tip angle of 42 degrees front and 5 degrees rear, with a maximum lift of 18.6 in and side shift of 26.8 in each way. The moldboard is 12.1 ft wide, 24.1 in high, and 0.9 in thick, capable of a blade pull up to 42,120 lbs at maximum weight. Standard operating weight is 33,630 lbs, with a maximum operating weight of 46,799.8 lbs. The machine measures 28.9 ft in length, 8.2 ft in width, and has a wheelbase of 20.1 ft. The articulation steering system allows a 22-degree angle and a 23.5 ft turning radius, while the front axle offers 2 ft ground clearance, 32 degrees total oscillation, and 20 degrees wheel lean. The 672D is equipped with a 106-gallon fuel tank, 24-volt electrical system, and radial 14.00R24 tires, making it a reliable and efficient solution for heavy-duty grading tasks.
