JOHN DEERE 770G MOTOR GRADERS

Technical Description

The John Deere 770G is a full-size motor grader engineered for road construction, maintenance, and finish grading applications. Powered by a John Deere PowerTech PSS 9.0L turbocharged diesel engine, it delivers 255 net horsepower at peak with 969 lb-ft of torque and a 54% torque rise characteristic, providing excellent lugging ability through challenging terrain. The machine features a 12-foot moldboard with 24-inch height and generates 34,173 pounds of blade pull force, enabling both precise fine grading and aggressive earthmoving. Its articulated frame design delivers a 22-degree articulation angle with 32-degree axle oscillation and ±20-degree front wheel lean for superior maneuverability in confined spaces and on uneven ground. The eight-speed PowerShift Plus transmission with eight forward and reverse gears enables smooth power delivery across varying grades and soil conditions. The hydraulic system utilizes a closed-center, pressure-compensated load-sensing pump delivering 56 gallons per minute at 2,750 psi maximum pressure. Operating weight is approximately 42,825 pounds with a maximum capability of 55,000 pounds when equipped with optional attachments. Standard 14R24 or optional 17.5R25 tires provide traction on diverse surfaces. The machine measures 29 feet in overall length with a 20-foot, 3-inch wheelbase and 15.7-foot operating width. Industry-leading visibility and ergonomic controls minimize operator fatigue during extended shifts.
