ON THE CUTTING EDGE
  • Power without compromise Choose between variable and constant engine speeds in normal and performance modes. Drivetrain and hydraulic functions are powerful, responsive, and quick, to deliver
    exceptional productivity in the most demanding applications.
  • E-Drive innovation Innovative E-Drive transmission system delivers premium performance and efficiency. System includes an engine-driven generator plus an inverter to control the electric motor
    that drives a simplified PowerShift transmission.
  • Move more with less Efficiency is outstanding, with up to 18-percent more tons moved per gallon of fuel burned than top competitors.
  • See it like never before New Advanced Vision System includes two digital cameras mounted on the rearview-mirror platforms that integrate with the rearview camera for a single display on a dedicated in-cab monitor. Overlayed within the monitor’s rear-camera view, dynamic reversal projected-path lines help operators visualize the loader’s anticipated reversal path based on its articulation, for sight
    lines to people or objects directly within the path.
  • Material matters SmartWeigh option features dynamic weighing technology that allows operators to weigh without interrupting workflow and removes the need to lower and reraise the boom after tipoff. Shared through the onboard monitor, SmartWeigh is easy to calibrate and effortlessly integrates with JDLink™ so you can track and visualize payload data from almost anywhere. Available
    as a factory-installed or field-kit option, you can also try SmartWeigh at a low cost for 250 machine hours.
  • Smooth operator Purpose-built PowerShift transmission provides smooth control through four forward speed ranges. Direction changes are accomplished by the electric motor, completely eliminating shifting in some truck-loading applications.
  • Make a good impression Running wide open at 1,600 rpm, the in-cab noise rating is just 70 dBA. Reduced exterior noise makes the 644 X-Tier a great choice when working in residential areas.
  • Level up AutoLevel enables near-perfect parallelism throughout the boom-raise-and-lower cycle, letting operators set their desired attachment angle to within ± two degrees.
  • Field proven John Deere E-Drive technology in our 644 and 944 Wheel Loaders has collectively logged over three million field hours — a testament to the durability and performance of our transmission components and systems.
  • The coast is clear Coast-control feature slows the loader down without the operator having to touch a pedal, helping extend service-brake wear life.
  • Creature comforts Spacious cab boasts ample legroom and features ergonomically placed controls, foot pedals, and sealed switch module. Seat-mounted hydraulic controls include two programmable multifunction buttons and intuitive electro-hydraulic (EH) controls.
  • Integrated controls With the capacity to control up to six functions on the single hydraulic joystick, cycle times and productivity when using hydraulic attachments are improved.
  • The bucket list Enhanced-performance buckets with integrated spill guards, curved side cutters, and impressive rollback maximize bucket-fill performance and material retention. Choose from hi-vis
    and JRB-style couplers to boost fleet versatility and machine utilization.
  • Time to take sides All daily service points including fuel are conveniently grouped on the left side of the machine at ground level, for easy access. Hinged doors enable wide-open access to the
    engine, cooling system, and other components.
