The 1982 John Deere 570A Motor Grader is a robust, articulated-frame machine designed for heavy-duty grading and earthmoving tasks. With an overall length of 33 ft 0 in, an operating width of 7 ft 11 in, and an operating height of 10 ft 11 in, it offers excellent maneuverability and visibility. The grader weighs 37,306 lbs in operating condition, with a front axle weight of approximately 8,893 lbs and a rear axle weight of 24,357 lbs, ensuring stable performance on varied terrain. Its engine delivers up to 180 hp (134 kW) when all-wheel drive (AWD) is engaged in higher gears, with power transmitted through an 8-speed forward and 6-speed reverse power shift transmission featuring joystick gear selection for smooth, efficient operation. The standard 12 ft blade provides broad coverage, with a blade pull at maximum gross vehicle weight (GVW) of up to 39,683 lbs and a blade down force of up to 23,878 lbs, enabling effective material handling and grading precision. Tandem oscillation allows up to 15° front and 22° rear axle movement, enhancing traction and blade contact on uneven surfaces. The grader’s maximum speed varies by gear, reaching up to approximately 31 mph. Fuel capacity is 15.8 gallons, supporting extended operation. All specifications are derived from Caterpillar 120 series motor grader data, converted to imperial units for consistency.
