644K Hybrid delivers up to 25-percent better average fuel efficiency than its conventional IT4 counterpart with a lockup torque converter. In applications such as V-pattern truck loading, fuel savings will be even larger.
EPA IT4/EU Stage IIIB 6.8-L diesel runs at a constant 900, 1,200, 1,500, or 1,800 rpm. Constant speed reduces engine wear, noise levels, and fuel consumption. Top speed provides maximum power and productivity, while the slower settings increase efficiency.
Hybrid-electric drive smoothly and efficiently recaptures energy to slow the loader when the operator lets off the accelerator. This lessens the load on the engine and reduces fuel consumption.
The NeverGrease™ option includes a pin-joint system for the linkage and boom joints that eliminates greasing, extends pin-joint life, and provides consistent life across the system.
Quad-Cool places the radiator, air-conditioner condenser, intercooler, and hydraulic, transmission, and optional axle coolers in a unique boxed configuration that's isolated from engine heat.
All daily service points, including fuel, are grouped on the left side for quick and convenient ground-level access. Sight gauges enable quick fluid-level checks.
Sealed-switch module keeps out dust and moisture while eliminating nearly 100 wires. Prevent unauthorized machine operation with keyless-start requiring a numeric pass code.
Optional rearview camera and radar object-detection system
