Productivity
PowerTech™ Deere diesel delivers best-in-class net horsepower, net peak torque, and a whopping 60 percent torque rise.
When rpms drop, horsepower actually goes up. John Deere Power Bulge advantage develops 15 percent more power to help maintain good boom and bucket speed into the pile.
You won't find a smoother shifting loader. The Power Shift torque-converter transmission employs smart-shift technology to continuously evaluate speed and load conditions, and adjusts clutch-pack engagement to suit. For extra productivity without extra effort.
Low center of gravity and optimized fore-and-aft balance delivers unmatched stability and impressive full-turn tipping load capacities.
Best-in-class powertrain & hydraulic performance maintains quick ground speeds & boom lift, even on steep ramps. For faster trips from pile to hopper.
Comfort
Choose from single-lever joystick or two-lever fingertip pilot-operated hydraulic controls. Both include John Deere's innovative Quick Shift feature that allows pushbutton gear changes.
Standard joystick steering offers exceptional control & fatigue-bating comfort for V-pattern truck loading. Also adapts to ground speed, making it useful for load-and-carry operations.
Backlit pushbuttons in the sealed touchpad allow fingertip control of numerous functions. No tools required to adjust boom height kick-out, return-to-carry, or return-to-dig.
Standard air-ride seat adjusts multiple ways for extra comfort. All-around visibility is unobstructed and 11 automotive-style louvers provide effective airflow to help keep the view clear, the spacious cab comfortable.
Uptime / Service
Quad Cool™ places the radiator & transmission, hydraulic, axle, and air-to-air coolers in a separate compartment for extra efficiency & decreased debris buildup. Optional reversing fan back-blows every 30 minutes to help keep cores clean.
All daily service points including fuel are on the left side for quick and convenient ground-level access.
Extended engine, hydraulic, and transmission service intervals contribute to low daily operating costs.
Remote fluid sample & diagnostic ports enable technicians to perform preventative maintenance & troubleshoot problems more quickly.
If something goes wrong, an advanced diagnostic monitor gives easy-to-understand messages and even offers possible solutions to help get you back up & running quickly.
