Key Features
Interim Tier 4-certified diesel.
Powerwise™ III management system.
Hydraulically driven fan runs only as needed.
Rigid, reinforced D-channel mainframe.
Productivity
The enhanced Powerwise™ III engine/hydraulic management system commands more horsepower and additional arm and bucket digging force to perfectly balance engine performance and hydraulic flow. Three productivity modes allow you to choose the digging style that fits the job. High Productivity delivers more power and faster hydraulic response to move more material. Power delivers a balance of power and speed for normal operation. Economy limits top speed and helps save fuel.
Low-effort joysticks, unmatched metering, and smooth multifunction operation deliver the control and finesse you need for utilities work.
Generous flow, arm force, and swing torque help speed cycles. So you can do your best to stay on schedule or ahead of the weather.
When the task calls for a little extra, simply press the power-boost button on the right-hand control and muscle through.
Engine
The EPA IT4/EU Stage IIIB technology utilized in the 670G LC diesel engine is simple, fuel efficient, fully integrated, and fully supported. It employs field-proven cooled exhaust gas recirculation (EGR) for reducing NOx, and a diesel particulate filter and a diesel oxidation catalyst to reduce particulate matter. Periodic active and passive regeneration automatically cleans the filter without impacting machine productivity.
Auto-idle automatically reduces engine speed when hydraulics isn’t in use. Auto shutdown further conserves precious fuel.
Service and Uptime
Wide slip-resistant steps and “Deere-walk,” sturdy handrails, and large easy-to-open service doors provide convenient access to grouped service points and major components.
Diesel particulate filter is easily removed through the top of the engine compartment. Minimum service interval is 4,500 hours, and can be done by your John Deere dealer.
Large fuel tanks and 500- and 4,000-hour engine and hydraulic oil-service intervals increase uptime and reduce daily operating costs.
Centralized lube banks place difficult-to-lube zerks within easy reach. Convenient color-coded chart helps ensure that nothing gets overlooked.
Vertical spin-on fuel filters and hydraulic and engine oil filters simplify service and help minimize messes. Fresh-air cab filter can be quickly serviced from outside the cab. Where it’s more likely to get done.
