KEY FEATURES
SmartWeigh™ Technology
SmartWeigh™ is a John Deere-designed and supported payload weighing solution that’s easy to calibrate to deliver accurate measurements and dynamic weighing capabilities.
New Mirror-Mounted Cameras
Enhanced visibility and radar object detection systems improve awareness and can help prevent costly damages.
Auto Level and Z-Bar Link
New P- and X-Tier utility loaders now have Auto Level, which helps to reach near-perfect parallelism throughout the boom raise and lower cycle. Enhanced performance buckets and Z-Bar linkage on P- and X-Tier utility loaders help maximize productivity.
Redesigned All-Day Comfort Cab
The updated cab in the John Deere utility loader lineup provides operators with a top-notch workspace. It includes various features to keep operators comfortable and productive, no matter the task.
Increased Functionality with Electrohydraulic (EH) Controls
EH controls provide increased functionality, enabling operators to customize machine operations according to their preferences. This customization enhances productivity across a wide range of jobsite applications.
Innovative John Deere E-Drive System
The Electric Drive (E-Drive) system is made up of a brushless electric generator and motor, power electronics (inverter), an electric brake resistor, and a simplified PowerShift™ transmission. E-Drive provides customers with enhanced size class performance, ease of operation, and longevity. The entire system dynamically adjusts engine speed to meet tractive and hydraulic loads, ensuring that 644 X-Tier loaders can efficiently maintain stockpiles, heap hoppers, and load trucks.
Industry-Leading Sustainability Benefits
The 644 X-Tier is the most fuel-efficient machine not only in its size class but also in the next class up. This means operators can process a greater amount of material through the crusher or asphalt plant while minimizing fuel consumption. Its design efficiencies also contribute to environmental impact reduction, resulting in lower carbon emissions and a reduced environmental footprint.Related
