John Deere 944K Hybrid Wheel Loader Reaches 1 Million Field Hours

  • The 944K Hybrid Wheel Loader reached 1 million operating hours in the field, showcasing the durability and performance of the John Deere electric drive solution.
  • Since its launch in 2015, the 944K has provided customers with a reliable, highly productive, cost-effective equipment solution designed with their needs in mind.

A test meant to the durability and performance of the JohnDeere machines, the 944K HybridWheelLoader has logged 1 million operating hours in the field. Withtheachievementofthismilestone, customers can be confident in the 944K’s quality and reliability, evening the toughest of conditions.

“Whenever we develop a machine, customer needs, such as durability, productivity, profitability and low operating costs, are always at the forefront of our designs. Byreachingthe 1 million-hour mark on our 944K loaders, we are affirming that electrically driven machines offer proven durability and performance advantages for our customers,” saidGrantVanTine, solutions marketing manager, JohnDeere. “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 Hybridmodelprovidescustomerswith a reliable, efficient, cost-effective solution. The 944K Hybrid features a 536-horsepower, FinalTier 4 engine, which delivers impressive torque and responsiveness while maintaining good boom and bucket speed. AtCornejo&Sons (Summit Materials), the 944K replaced a size-class large r competitive wheel loader. “The 944K meets our production requirements as well as our previous piece of equipment, and at a lower-cost,” said AdamWare, site manager for Cornejo & Sons (Summit Materials), which owns a 944K Hybrid Wheel Loader. “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.”
