LOADING HAULING Ease of Operation, Fuel Efficiency Drive John Deere 644K Hybrid Loader The new 644K Hybrid Wheel Loader from John Deere is now available for value���driven customers looking to lower own��� ing and operating costs. The 644K Hybrid utilizes two sources of energy: diesel and electric. The hybrid loader cap��� tures regenerated energy as it���s being created and uses it to power the machine. consumption up to 25 percent, helping contractors lower their daily operating costs,��� said John Chesterman, global product marketing manager for 4WD loaders, John Deere Construction & Forestry. ���But there is so much more to the 644K than fuel��� efficiency. The hybrid���s features make it easy to control, virtu��� ally becoming an extension of the operator.��� ���John Deere is committed to delivering the right hybrid solu��� tions to meet our customer needs today, tomorrow and well into the future,��� said Andrew Kahler, engine and driveline product marketing manager, John Deere Construction & Forestry. ���The 644K Hybrid is a result of our dedication to in��� tegrating the best technology available to better the industry and provide our customers superior uptime and productiv��� ity, while lowering daily operating costs.��� Another benefit of the hybrid design is noise reduction on the jobsite. Since the engine runs at a constant speed instead of increasing and decreasing speed as the machine is worked, the engine noise is continuous and therefore less noticeable to both the operator inside the cab and by��� standers outside. Engine The 644K Hybrid is equipped with a John Deere PowerTech 6.8���L IT4/Stage IIIB engine that runs at an operator���selected constant speed from 900 to 1,800 rpm. The hybrid boasts a net 229 hp and is equipped with all the key features of the conventional John Deere K���Series Wheel Loader line. During operation, a simplified, PowerShift, countershaft��� style transmission maintains smooth shifting for added pro��� ductivity whether the operator is stockpiling, truck loading or ramp climbing. The 644K Hybrid has four operating speed ranges, but no reverse gear or clutches as direction changes are performed by the electric motor. An integrated, spring��� applied, hydraulically released wet���disc park brake requires reduced maintenance and increased machine uptime. The machine���s hybrid technology delivers performance that is equal to or better than the conventional 644K, depending on the application. The engine���s constant operating speed maintains continuous hydraulic flow at all times, which de��� livers crisp hydraulic responsiveness and reduces cycle times. The electric motor smoothly delivers torque resulting in fluid operation and a smoother ride. As a result, the 644K Hybrid delivers optimal performance for novice and experi��� enced operators alike. ���With fuel prices on the rise, the 644K Hybrid can reduce fuel IDLERS | PULLEYS | IMPACT BEDS | ACCESSORIES QUALITY.
