How can we help?
Description
- Net Power: 60 kW (80 hp) at 2,200 rpm
- Operating Weight: 7 959–8 522 kg (17,510–18,752 lb.)
- Track on Ground: 2 184 mm (86 in.)
Models
Hydrostatic Transmission
Infinitely variable range to 9.7 km/h (6.0 mph) allows total flexibility to match ground speed to the load.
Counter-rotation boosts productivity by enabling an operator to overcome heavy corner loads and quickly reposition the blade on the go. Provides space-saving spot turns, too.
Simple Maintenance
Available quick fluid-evacuation system helps speed servicing. 500-hour engine oil and 2,000-hour transmission and hydraulic fluid intervals decrease maintenance downtime and expense.
Cab and Controls
Cab-forward design allows a commanding view behind, below, and beyond the blade. Side and rear visibility from inside the cab is open to the surrounding jobsite.
Sealed-switch module (SSM) allows low-effort control of keyless start and enables exclusive features such as turbocharger cool-down, auto shutdown, and Eco mode.
Total Machine Control enables an operator to customize control of decelerator mode and response, forward/reverse ground speed, steering modulation, and forward/reverse speed ratios, and even record machine usage.
Grade-Control Ready
When you order your dozer with electrohydraulic (EH) controls, it’s grade-control ready, giving you the ability to add the grade-control system of your choice. Optional Slope Control provides in-depth factory integration and is supported by your John Deere dealer.
Optional Slope Control system provides simple-to-use grade control that allows operators to set a desired slope and hold grade through changes in existing terrain. It helps both new and veteran operators hold grade with less effort and without needing an external elevation reference.
Engine
EPA Final Tier 4 (FT4)/EU Stage IV diesel meets emission regulations without loss of power or torque. Four-valve head delivers increased intake-air and exhaust-gas flow for each wet-sleeve cylinder, for long-lasting performance.
Standard Eco mode maximizes fuel usage by up to 20 percent compared to conventional torque-converter transmissions, automatically adjusting engine rpm and powertrain settings based on load, without loss of performance.
