Technical Description

The 1985 Champion 100T motor grader represents a heavy-duty road construction machine equipped with a 7.01L displacement engine delivering 176–196 net horsepower. The machine features a closed-center, parallel-circuit hydraulic system powered by a variable piston pump capable of producing 3,503 psi output pressure at 2,200 rpm, with system flow ranging from 0–40.9 gallons per minute. The steering system includes a 159 cc/rev metering capacity with a maximum front steering angle of 47.5° and frame articulation of 20° left and right. The grader's moldboard operates through a 360° rotational circle drive, with maximum lift of 18.9 inches and cutting depth capability of 28.9 inches. Ground clearance measures 10 inches at center, while front axle oscillation reaches 32° total. The rear scarifier attachment spans 84.1 inches with nine shanks spaced 9.8 inches apart, achieving maximum scarifying depths of 11.1 inches. Brake systems comprise 226.3 square inches of lining area with hydraulic-actuated drum-type parking brakes capable of holding 30% grades per ISO 3450:2011 standards. The transmission employs a gear pump supplying 20.6 gallons per minute at 232–261 psi for clutch operation. Electrical systems include direct electric starting with a 12V battery and 150-amp 24V alternator. Operating specifications indicate maximum engine RPM of 2,000–2,200 with ambient temperature capability to 122°F, while the moldboard blade extends approximately 14 feet, representing one of the largest production graders commercially available.
