After its most successful ConExpo show, John Deere is now offering a 96-month (eight year)/20,000-hour power electronic components warranty on its 944K hybrid wheel loader. The warranty is retroactive to existing machines in the field and provided on new 944K loaders through Oct. 31, 2018.

The warranty includes a 96-month (eight year) or 20,000-hour (whichever comes first) non-prorated assurance on wheel motors, generators, power inverters and brake retarders. Certain customer conditions must be met to maintain warranty coverage, including component rotation between 15,000 and 18,000 hours; drive voltage cables replacement between 15,000 and 18,000 hours; and an annual dealer machine inspection.

“We continue to build confidence in our hybrid technology and the high-design life of machine components,” said Jason Daly, director, customer and product support, John Deere Construction & Forestry. “As our hybrid experience continues to grow, we feel strongly that this 20,000-hour warranty allows a customer the opportunity to go through a 15,000-hour rebuild/re-life without the expense of worrying about power electronic components.”

The 536 horsepower 944K hybrid wheel loader has an EPA Interim Tier 4 engine, and it can provide significant fuel savings over 9-cubic-yard loaders with conventional drivetrains, Deere said. The production-class wheel loader’s brushless AC generators and motors, water-cooled brake resistors and solid-state power electronics are designed to deliver reliable, long-term performance to quarry and large-load applications.
