John Deere - 844K-III

  • This field is for validation purposes and should be left unchanged.
  • Key Features
    • Increased Engine Power
    • Heavy-duty axles
    • Standard five-speed transmission
    • Advanced onboard diagnostics
    Hydraulics
    • Increased hydraulic forces, engine power, and torque make quicker work of tough aggregate piles.
    • Hydraulic plumbing has been improved and articulation-joint and linkage pins enlarged to help boost productivity.
    • Bulkhead fittings eliminate long hoses, simplifying replacement and component exchange.
    • Hydraulic tank is positioned behind the cab for easy access, and hoses have been routed away from other vital operating components, for longer wear life.
    Engine

    Our FT4/Stage IV diesels meet emission regulations without sacrificing power or torque.

    This technology is simple, fluid efficient, fully integrated, and fully supported. It employs field-proven cooled exhaust gas recirculation (EGR), easy- to maintain high-uptime exhaust filters, and selective catalytic reduction (SCR).

    Productivity
    • Bigger material-handling buckets reduce fill time in processed aggregates, better retain loads, and ultimately conserve fuel.
    • Low center of gravity and optimized fore-and-aft balance deliver solid stability and full-turn tipping-load capacities.
    • Transmission shift logic and programmable clutch cutoff have been improved, for increased productivity in a variety of conditions.
    • Fuel-efficient John Deere PowerTech™ engines provide generous displacement, power, and lugging ability.
    Serviceability And Uptime
    • Quad-Cool design places coolers in a unique boxed configuration that’s isolated from engine heat, for increased efficiency and durability.
    • Standard hydraulic reversing fan automatically reverses at predetermined intervals, or can be programmed through the monitor to eject debris from the cooler cores.
    • Color-coded fluid-sample and diagnostic test ports help speed preventative maintenance and troubleshooting.
    Other Features and Options
    • Slip-resistant steps, platforms, and handrails provide uninterrupted three-point access.
    • New slip-resistant plates at the rear of the machine enable more sure-footed grip.
    • Want to increase traction, flotation, and stability? Spec the low-profile tire option.
    • With larger material-handling buckets, the aggregate handling option can load out 24 to 26 short tons of non-heaping, lower-density processed matter in just two passes. With heavier materials, achieving 12 to 13 tons is not a problem.
