John Deere
John Deere D-Series motor graders feature several enhancements that boost productivity: a mid-mount scarifier for the 670D, 672D, 770D and 772D models; an Integrated Grade Control (IGC) package; and a new low-speed precision mode and improved steering for all-wheel-drive machines. The 11-tooth mid-mount scarifier option is mounted between blade and front wheels for ground penetration and visibility. The Integrated Grade Control option features plug-and-play convenience and is compatible with sonic, laser or GPS systems. The hydrostatic system senses steering angle, and increases pull to allow the machine to turn tighter in 6WD. (

LeeBoy
The LeeBoy 785 motor grader is engineered to perform large motor grader functions such as road building, ditch cutting and even fine grading. The 23,500-lb machine features 20º boom articulation in either direction, front wheel lean, hydraulic power steering, a gear-driven turntable, and 12-ft sliding and tilting moldboard. The 785 motor grader also features a front-mounted scarifier for ripping power, a pressure-compensated pump system and enclosed cab. It is powered by either a Cat 127-hp or Cummins 130-hp diesel engine and has a 6-speed powershift transmission. (

New Holland
New Holland motor graders range from 140 to 200 hp with standard blade lengths from 12 to 14 ft, and are engineered to perform in every application. The operator’s cab is mounted behind the articulation point, providing an excellent view of both ends of the working blade, enabling the operator to maneuver and respond quickly. With heavy-duty, box-section construction, the rugged frames of the G140, G170 and G200 motor graders are designed to endure the most rigorous working conditions. Durable front axles stand up to the toughest grading jobs and oscillate up to 19º. Featuring thin corner posts and doorframes, and more than 85 sq ft of glass area, the cab provides an excellent view in all directions. (

NorAm
The NorAm 65E compact grader features big grader design, including an articulated frame, torque proportioning rear axle, wheel lean and inch control in the body of a compact motor grader. The NorAm grader weighs 16,800 lbs and has a small turning radius for working in confined spaces. The drivetrain with a Cummins engine and ZF full powershift transmission/torque converter delivers exceptional power and torque to the tandems. The big grader design A-frame/circle configuration provides the strength and stability for the 10-ft or 12-ft rollaway moldboard to perform with precision and ease. Standard air ride seat and low-effort hydraulic controls contribute to operator comfort and productivity. The grader is available with a canopy or cab, as well as air conditioning. (
