Power and precision converge with the new grade guidance technology-equipped John Deere 470G LC Excavators. First introduced for the 210G LC and 350G LC Excavators, John Deere developed this solution in cooperation with Topcon Positioning Group. The integrated grade guidance system provides the operator with the bucket’s location in relation to a 2D reference or 3D design surface. This information arms operators with the detail they need for precision excavation projects, such as digging trenches for pipes, shaping ditches or slopes or digging structure foundations.
“Accuracy and productivity are critical to our customers, and the new integrated system provides them with just that,” said Jonny Spendlove, excavator product marketing manager, John Deere Construction & Forestry. “With this integrated solution, the system’s sensors are protected from damage and the display is conveniently placed in the cab. Additionally, this technology is fully supported by the customer’s John Deere dealer, eliminating downtime and expediting earthmoving operations.”
Equipped with a display in the operator station, the grade guidance system provides operators with the elevation and position of the bucket cutting edge with respect to a target plane (2D) or design surface (3D). Support through the JDLink™ telematics system provides information on system utilization and allows rapid diagnosis of problems.
Engine
The EPA FT4/EU Stage IV engine employs field-proven cooled exhaust gas recirculation (EGR) for reducing NOX, and a diesel particulate filter and diesel oxidation catalyst to reduce particulate matter.
Ash-service intervals for the diesel particulate filter (DPF) are condition based, with machine alerts notifying the operator before service is required.
Highly efficient, hydraulically driven fan runs only as fast as needed, reducing noise, fuel consumption, and operating costs. The cooling systems keep things running cool, even in high-trash environments and high altitudes. Standard reversing feature backblows cooler cores to help keep them clean automatically or at the touch of a button.
Controls
Ergonomically correct short-throw pilot levers provide smooth, predictable fingertip control with less movement or effort.
Push buttons in the right lever allow fingertip control of auxiliary hydraulic flow* for operating attachments.
Press the power-boost button on the right-hand control for extra digging power.
*Grade management not available with auxiliary hydraulics.
Durability
Bucket-to-arm pivot joint features a new heat-treated pin and flanged bushing made of forged steel, to double joint life in sandy digging conditions. High-strength floating-pin design extends pin-case hardening depth by 175 percent, boosting wear life and easing serviceability.
Standard control pattern-change valve and fuel shutoff are well protected yet conveniently accessible at ground level.
A John Deere exclusive, three welded bulkheads within the boom resist torsional stress.
Visibility
Wide expanse of front and side glass, narrow front cab posts, large overhead glass, standard deluxe LED lighting package, and numerous mirrors provide expansive all-around visibility.
