Deere's 944K Hybrid Wheel Loader has reached 1 million field hours since its introduction in 2015.

John Deere has announced that its 944K Hybrid wheel loader has logged 1 million operating hours in the field.

“Whenever we develop a machine, customer needs, such as durability, productivity, profitability, and low operating costs, are always at the forefront of our designs," said Grant Van Tine, solutions marketing manager, John Deere. "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. 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, Tier 4-F engine. At Cornejo & Sons (Summit Materials), the 944K replaced a size-class larger competitive wheel loader. “The 944K meets our production requirements as well as our previous piece of equipment, and at a lower cost,” said Adam Ware, site manager for Cornejo & Sons (Summit Materials). “The other machine burned about 24 gallons of fuel an hour, where the 944K burns around 9 gallons per hour while doing the same work.”

In addition to its fuel-saving capabilities, the 944K Hybrid has 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, Deere says.

Other 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, designed to virtually eliminate tire spin and slicing. 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.
