JOHN DEERE JD570 MOTOR GRADERS

Technical Description

The John Deere JD570 is a heavy-duty motor grader featuring a naturally aspirated 6-cylinder diesel engine producing 83 net horsepower at 2,300 rpm with maximum torque of 212 lb-ft at 1,300 rpm. It measures 24.4 feet in overall length with a 7.9-foot width over tires and incorporates a standard 12-foot moldboard blade with adjustable side shift capabilities (26.8 inches left, 31.3 inches right). The machine utilizes a power shift transmission with 8 forward and 4 reverse gears, achieving maximum forward speeds of 21.4 mph and reverse speeds of 6.8 mph, with an 18-foot turning radius enabled by 22-degree articulation steering. The hydraulic system employs a variable-displacement piston pump delivering 26.9 gallons per minute at 2,000 psi relief pressure, providing all-hydraulic control of blade and machine functions with no blade drift or creep through a closed-center system with built-in positive hydraulic locks. The grader features a 54-inch diameter circle with 360-degree rotation and 12.3-inch maximum lift height, while the oscillating front axle provides 30 degrees total oscillation with 20-degree wheel lean for enhanced slope stability. Operating weights total 20,278 pounds standard and 18,100 pounds maximum, with 5,500-5,800 pounds on the front axle and 12,600-13,600 pounds on the rear tandem axle. The machine accommodates a 50-gallon fuel tank and carries 21 gallons of hydraulic fluid capacity.
