How can we help?
Description
- Net Power: 190 kW (255 hp)
- Operating Weight: 19 425 kg (42,825 lb.)
- Blade Pull: 15 501 kg (34,173 lb.)
- Net Torque Rise: 54%
Models
Controls
- Eight armrest mounted, fingertip-actuated controls on Grade Pro (GP) models are arranged in the industry-standard pattern on each side of the standard steering wheel.
- Optional dual-joystick controls on GP models require significantly less wrist motion to articulate the motor grader than competitive joystick controls.
- Our G-Series models offer conventional lever-operated controls.
Productivity
- Featuring a fully sealed bearing and pinion that run smoother and quieter, the industry-leading design of the optional premium circle reduces operating costs while delivering 40-percent more torque and 15-percent more speed than a traditional circle. Contractors no longer have to compensate for wear in the circle, improving accuracy when using a grade-control system — especially impactful when coupled with the innovative John Deere SmartGrade™ system. And greasing intervals of only four zerks every 500 hours make the premium circle essentially maintenance free.
- Increased engine horsepower, torque, and blade pull produce generous power and lugging ability, to deliver more power to the ground, easily pull through tough spots, or tackle steep hills.
- Horsepower and torque are optimized for each gear to maximize performance no matter your application.
Engine
- When engaged, Eco mode reduces engine rpm in gears 1–5, optimizing fuel usage and decreasing operating costs by up to 10 percent.
- Auto shutdown turns off the engine after an operator-determined period of time. Saves fuel and reduces wear on engine, transmission, and hydraulic components.
Exclusive Automation
- New John Deere automation features designed to move you ahead in a big way include Machine-Damage Avoidance, Machine Presets, Auto-Articulation, Auto-Gain for Cross Slope, and Auto-Pass (available on Grade Pro [GP] models).
- Auto-Shift PLUS simplifies operation of both GP and G-Series, for machine operation without using the inching pedal.
Industry-First SmartGrade™ Configurations
- John Deere SmartGrade Motor Graders are fully integrated and calibrated from the factory, arriving at your jobsite ready to work.
- Integration into the SmartGrade cabin and structures helps shield key grade-control components such as wire harnesses and sensors from damage and theft.
Visibility
- All-around visibility is virtually unobstructed, with a clear view to the heel and toe, and behind the moldboard.
