The dependable, economical 644 G-tier is all business. From stockpiling and truck or hopper loading, to short load-and-carry tasks and material handling, this mid-size wheel loader’s got you covered. Its lower
initial acquisition cost doesn’t mean you have to sacrifice quality and support. The 644 G-tier delivers the rugged reliability and ease of operation you expect from John Deere — a company with over a half-century of experience designing and manufacturing exceptional wheel loaders.

  • Proven design and reliability The John Deere 644 G-tier leverages components and technology featured in both our current and former series loaders for decades. Powertrain, hydraulic, and electrical systems are the culmination of thousands of hours of proven experience in the field.
  • Minimal maintenance and operating costs Extended service intervals plus parts and fluid costs over 12,000 hours of usage are as much as 14-percent lower than the nearest competitor.
  • Peace of mind Renowned John Deere and dealer support, parts availability, and warranty help keep customers up and running.
  • Streamlined servicing All daily service points including fuel are conveniently grouped on the left side of the machine at ground level, for easy access. Hinged doors provide wide-open access to the  engine, the cooling system, and other components. Cooling package is isolated from the engine compartment, so the fan pulls fresh air that is not preheated through the coolers.
  • Maximize jobsite versatility In addition to current P- and X-tier options, the coupler accepts buckets and attachments dating to K-Series Loaders to help maximize machine utilization and fleet versatility.
  • Cab comfort Roomy cab features ergonomically placed joystick controls, foot pedals, and sealed-switch module. Seatmounted right-hand joystick includes integrated F-N-R switch. Optional air-ride seat increases the level of operator comfort.
  • User-friendly control The 644 G-tier features common controls that will be familiar to both novice and experienced operators. Optional front-differential lock provides additional traction in muddy or loose-material conditions. Pilot controls are intuitive to operate. In-cab adjustable boom-height kickout and return to carry as well as return to dig can be easily activated from the convenient
    touchpad, speeding production in repetitive applications.
  • Remote diagnostics and support To maximize uptime and lower costs, JDLink™ connectivity provides machine location, utilization data, and alerts to help you maximize productivity and efficiency. JDLink also enables John Deere Connected Support™. Dealers use Expert Alerts based on data from thousands of connected machines to proactively address conditions that may otherwise likely lead to downtime. Your dealer can also monitor machine health and leverage remote diagnostics and programming capability to further diagnose problems and even update machine
    software without a time-consuming trip to the jobsite.
  • Keep free of debris Optional programmable fan automatically reverses at predetermined intervals to keep coolers clean throughout the day. Or run individual cleaning cycles through the monitor.
