Move waste with haste

This loader is fortified to tackle even the toughest transfer-station duties. Extensive guarding keeps run-ins with obstacles from trashing machine uptime, and state-of-the-art electronics deliver long-term reliability. To keep things cool, hydraulic driven fans in the Quad-Cool™ system reverse automatically to blow away airborne trash. And the 624K WH's unrestricted visibility, low-effort controls, and comfortable cab help ease taking out the trash.

Features

KEY FEATURES

  • Unique Quad-Cool design helps keep our loaders cool in grueling conditions.
  • John Deere turbocharged Tier 3 diesels deliver impressive torque reserves up to 55 percent (624K/644K). For pullthrough power when the going gets tough.
  • Heavy-duty waste-handler buckets range from four to eight cubic yards. Third-function hydraulic valve is available for use with grapple buckets.
  • Optional high-lift booms increase dump height so you can move materials and push productivity to even greater heights.
  • Choose the axles that are right for you. Hydraulic front differential lock and conventional rear is standard; front and rear hydraulic differentials are available.
  • Heavy-duty wide axles are standard on the 744K.

CONTROLS

  • Industry-leading 360-degree visibility gives a clear view of the work ahead and obstacles around you.
  • Efficient HVAC system helps keep the view clear, the environment comfortable.
  • Sealed-switch module allows convenient, fingertip control of multiple machine operations.
  • Up front, a state-of-the-art multifunction monitor with easy-to-read gauges and messaging provides vital operating info at a glance.

IN-CAB COMFORT

  • Standard air-ride armchair seat adjusts multiple ways for extra comfort.
  • Independently adjustable louvers and defrosters provide effective airflow to help keep the glass clear and pressurized cab comfortable. Activated carbon fresh-air filter reduces odors.
  • Choose either joystick or two-lever pilot-operated control. John Deere PowerShift™ torque-converter transmission employs Smart-Shift™ technology to ensure smooth-as-silk gear changes.
  • Responsive steering and full 80-degree articulation increase maneuverability in tight quarters - for fast cycles and fewer three-point turns.
  • Return-to-carry, boom height kick-out, and return-to-dig are set with just a touch of a button. These advantages help speed production in repetitive loading applications.

MONITOR

  • Advanced, multi-language monitor with analog gauges and LED indicators provides: Vital and general operating information including transmission mode, gear, engine rpms, and ground speed.
  • Diagnostic readings of most sensors and switches, enabling technicians to quickly troubleshoot problems.
  • Customized machine settings that allow the operator to match the loader's operating characteristics to specific applications by preselecting transmission functions such as Quick-Shift and Auto-to-1st for maximum productivity.
  • Conveniently positioned switch module helps reduce operator fatigue with clearly visible backlit and sealed controls.
  • In-cab lockable master switch makes it easy to disconnect electrical power.


QUAD-COOL SYSTEM AND REVERSING FAN

  • Fan automatically reverses to help eliminate cooler-clogging buildup. Or select reversing through the monitor as required.
  • Quad-Cool system places the radiator, intercooler, air-conditioner condenser, and transmission and optional axle coolers in an independent package. Outside air flows through the perforated top, side panels, and coolers, and out the rear instead of drawing air through the engine compartment, for increased efficiency and durability.
  • Transmission oil cooler has its own air-intake screen for more efficient cooling.
  • Three-millimeter perforations act as a "first filter," preventing entry of most airborne debris. Anything that gets through the side screens easily passes through the cooler cores.
  • No stacked cores in these waste handlers. Both sides of all coolers are easily accessible.
  • Hinged grill and fan swing open a full 90 degrees, further simplifying cleanout.

GUARDING AND DURABILITY

  • Articulation joint shields and driveshaft guards resist trash buildup.
  • Front window bars protect glass without obstructing all-around visibility.
  • Axle guards help protect the seals and resist refuse wrapping.
  • Extreme-duty steps are mounted in close where they're less vulnerable. Their flexible design takes abuse and comes back for more.
  • Extreme-duty front loader frame cover, lower loader frame guard, transmission side covers, and boom cylinder and hydraulic line guards give additional impact and debris resistance.
  • High-intensity halogen driving and work lights are powerful and well protected. Optional ROPS-mounted gel-filled strobe light alerts bystanders of the machine's presence.
    Bolt-on hinged or optional hydraulic belly pans provide unmatched protection of the fuel tank and drivetrain. Hydraulic versions have built-in safety features that open and close easily for cleanout.
  • Self-adjusting inboard wet-disc brakes run cool, clean, and unexposed to corrosive materials. Optional extreme-duty axle cooling kit helps beat the heat for long-term durability.
  • Sealed-switch module keeps out dust, moisture, and debris, so it virtually never wears out. Job-proven touch pad eliminates rocker switches and nearly 100 wires and unsealed connections.
  • Electrical distribution center employs extremely reliable circuit-board technology and solid-state witches, eliminating the need for a multitude of wiring harnesses, fuses, relays, and connections.

UPTIME/SERVICEABILITY

  • Vertical transmission and engine oil and fuel filters allow quick and easy no-spill changes.
  • If something goes wrong, an advanced monitor gives easy-to-understand diagnostic messages and even offers possible solutions to minimize downtime.
  • Conveniently located sight gauges let you check fluid levels at a glance.
  • Centralized lube banks make greasing less messy.
  • Color-coded fluid sample and diagnostic test ports help speed preventive maintenance and troubleshooting. Noninvasive design helps prevent contamination.
  • Conveniently displayed periodic lubrication and maintenance chart helps ensure that nothing is overlooked.
  • Large hinged doors open wide, providing quick and easy access to the engine and Quad-Cool system.
  • Hydraulically driven variable-speed fan runs only as needed to help maximize fuel efficiency and reduce noise.
  • Four-thousand-hour hydraulic filter change interval and large fuel tanks help maximize uptime.
  • Both sides of all coolers are easily accessible, for quick and easy cleanout. Corrugated fine-mesh screen air cleaner efficiently filters the airflow.
