John Deere introduced its K-Series wheel loaders on Tuesday to we in the trade press. The 644 and larger models are available with an optional 5-speed transmission with lock-up torque converter, which Deere claims will improve fuel efficiency by 15 to 20 percent, particularly in stockpiling and ramp-climbing applications.
This video shows how Deere demonstrated the lock-up torque converter's advantage at their Sacaton, AZ, demonstration grounds Tuesday.
The K Series is comprised of eight models in the 2- to 8-cubic-yard range, including the all-new 524K (a 125-horsepower, 27,100-pound machine with 2.75-cubic-yard standard bucket and static tipping load of 22,700-pounds).
The K Series comes with a lockable front differential, and offers the option of a lockable rear differential. Differentials can be locked on the roll, and an auto diff lock feature reads ground speed using radar and compares it to transmission output speed. When the two don't match up, the system knows a wheel is spinning and locks up the differential.
The 544K through 844K now can be purchased with joystick steering, which enables operators to start the loader with the push of a button. A security mode prevents engine starting until a code is entered on the sealed keypad. Special codes can be set for the owner, operator and transport, allowing various levels of access to the machine.
The new electronic monitor also displays payload-weight data courtesy of an embedded John Deere payload weighing scale powered by Loadrite.
An optional rear obstacle detection system provides an alert if any object is in the loader’s direct path while backing up. It is combined with a rear-camera which displays through the LCD monitor.
NeverGrease Pins have an exclusive sealed design that Deere says never needs greasing. The pins are a feature on the 544K through 844K.
