Moline, Ill. – The John Deere 944K Hybrid Wheel Loader has logged one million operating hours in the field.
“By reaching the 1 million-hour mark on our 944K loaders, we are affirming that electrically driven machines offer proven durability and performance advantages for our customers,” said Grant Van Tine, John Deere solutions marketing manager. “We’re always looking for new ways to improve upon the equipment our customers need and can use our field-proven design to develop and perfect even more solutions in the future.”
First launching in 2015, the 944K Hybrid features a 536-horsepower, Final Tier 4 engine, which delivers impressive torque and responsiveness while maintaining good boom and bucket speed.
The 944K Hybrid also incorporates other features to deliver reliable, long-term performance, especially in quarry or large loadout applications. Most notable are the brushless AC generators and motors, water-cooled brake resistors and solid-state power electronics. The 944K’s electric drive system significantly reduces operating costs for customers compared to conventional drivetrains by eliminating torque converter and transmission rebuilds at mid-life.
Other key features include standard traction control, which automatically limits torque to any wheel when slippage occurs, increasing machine traction in poor underfoot conditions, and enhanced rimpull control. Coast control reduces service-brake wear and includes functions, like dynamic braking in a hydrostatic transmission, slowing the loader without touching a pedal and helping to reduce service-break component wear.
