Technical Description

The John Deere 670D is a heavy-duty tandem-drive motor grader equipped with a turbocharged 6-cylinder PowerTech 6068H diesel engine delivering 185 net horsepower at 2000 rpm. This engine produces impressive torque characteristics, generating 554 lb-ft in lower gears, escalating to 625 lb-ft in top gears, providing excellent low-rpm pull-through performance. The transmission features 8 forward and 8 reverse gears with PowerShift direct-drive technology, enabling travel speeds up to 24.9 mph in both directions. The moldboard is 12.1 feet wide with a 60-inch diameter circle, featuring 42-degree front and 5-degree rear blade tip angles, capable of 360-degree rotation. Maximum blade lift reaches 18.6 inches above ground, while side-shift capability extends 26.8 inches left and right. The blade delivers 28,220 pounds of pull force at maximum operating weight. Dimensionally, the grader measures 28.9 feet in overall length with an 8.3-foot width over tires and 20.1-foot wheelbase. Front axle ground clearance is 2.1 feet with 32-degree total oscillation and 20-degree wheel lean for superior ride quality and grading precision. The variable-displacement piston hydraulic pump supplies 54.7 gpm at 2750 psi relief pressure for responsive moldboard control. Standard operating weight is 32,010 pounds, with maximum operating weight reaching 37,790 pounds. The 106-gallon fuel capacity and 14.1-gallon hydraulic fluid capacity support extended operational periods. The articulation angle of 22 degrees with a 23-foot turning radius enables excellent maneuverability on jobsites, making this machine ideal for road maintenance, land development, and heavy grading applications.
