The 670G/GP Motor Grader's tall mainframe lets these highly productive graders shoulder larger loads and navigate more easily over obstacles. Provides plenty of clearance for a mid-mount scarifier, and simplifies blade setup and operation, too. You won't find an easier-running grader, either. Our exclusive Event-Based Shifting (EBS) transmission delivers smooth-as-silk gear and direction changes, for exceptional control and grading precision without extra effort. There's nothing else like it.
• Final Tier 4-certified engine.
• All models come equipped with steering wheel (GPs also come with lever steer).
• Standard hydraulically driven cool-on-demand reversing fan.
• Trouble-free serviceability.
GRADE PRO (GP)
• Automated cross-slope simplifies holding a consistent slope by reducing operation to a single lever. An operator simply selects the desired slope and the side of the blade that will be manually controlled. Once set, the system automatically adjusts the opposite blade-lift cylinder to maintain the slope. It's a Grade Pro exclusive that helps veteran operators be their best and inexperienced operators get up-to-speed more quickly.
• For unsurpassed productivity with a grade-control system, opt for a GP model. Eight armrest-mounted fingertip-actuated controls, including steering lever, are arranged in the industry-standard pattern on each side of the steering wheel. No extra levers required for grade control. Instead, knob-integrated pushbuttons provide convenient, fingertip activation.
• At the touch of a button, return-to-straight automatically straightens an articulated frame. For quicker work cycles.
• The auxiliary controls now have individual forward and backward roller switches. This allows for integration of the controls into the right hand pod for better multifunctioning and controllability. (Grade Pro [GP] option only.)
• John Deere PowerTech FT4/Stage IV diesel engines meet stringent emission regulations without sacrificing power or torque. Plus, they deliver even better total fluid efficiency than the IT4/Stage IIIB engines they replace.
• Ash-service intervals for the diesel particulate filter (DPF) are condition based and may not be necessary until the first engine overhaul. Machine application, regular maintenance practices, and type of lubrication oil impact intervals.
• Exhaust filter operation and maintenance status are indicated with on-screen displays.
• Large service doors open wide, and same-side daily checkpoints are conveniently grouped for easy ground-level access. Standard left-side (and optional right-side) compartment lights illuminate the way.
• Available quick fluid-service ports help speed servicing to increase uptime. 500-hour engine oil/filter; 2,000-hour transmission, hydraulic, and axle filters; 2,000-hour transmission and axle oil-service, 4,000-hour hydraulic and tandem oil-service and 6,000-hour engine coolant service intervals minimize maintenance.
• Ground-level fuel and nearby diesel exhaust fluid (DEF) fill access help speed servicing for more uptime. There's also a fast-fuel option available.
• Maintenance personnel will appreciate the unique easy-access hydraulic, transmission, and differential filter bank.
• Most zerks are grouped in banks for quick and easy greasing. Conveniently displayed periodic lube and maintenance chart helps ensure that nothing's overlooked.
• Exclusive ball-and-socket draft-frame pivot and seven-position saddle provide best-in-class blade setup and improved ditch cutting, ditch cleaning, and reach outside the tires.
• Long-term durability is bolstered by larger-than-usual articulation joint roller bearings.
• Narrow center console and streamlined saddle bring the blade and front tires within focus. Even the area beneath the front axle is clearly visible, so you can see oncoming obstacles. On GP models (shown), control linkages are eliminated and large lower front windows further enhance visibility.
• NeverGrease™ is the word for significant savings in operating costs. These no-maintenance pin joints eliminate numerous zerks and the attention they demand.
• High-strength circle and draft frame withstand high-impact loads. Available blade-impact system further protects structural components from damage caused by run-ins with obstructions.
• Purpose-built PowerShift™ transmission employs durable heavy-duty clutches and bearings, for reliable performance, shift after shift.
• With five true working speeds below 16 km/h (10 mph) and a top speed of 45 km/h (28 mph), it’s easy to match ground speed to the work. Autoshift option automatically shifts gears four through eight, for even easier operation.
