John Deere Releases New Marine Auxiliary Engines

John Deere Power Systems is pleased to introduce the new 6090HFM85 and 6135HFM85 marine engines specifically designed for radiator-cooled marine gen-set and auxiliary applications. The new PowerTech™ 6090HFM85 is rated for variable speed at 242 kW (325 hp) at 2000 rpm and for generator drive and constant speed auxiliary at 262 kW (351 hp) at 1800 rpm. The PowerTech 6135HFM85 is rated for variable speed at 373 kW (500 hp) at 2000 rpm and for a generator drive and constant speed auxiliary at 458 kW (614 hp) at 1800 rpm.

The new marine engines are well-suited for gen-set, constant speed and variable speed auxiliary applications, particularly when wet manifolds and marine society classification certificates are desired or required. The ratings of both engines meet U.S. Environmental Protection Agency Marine Tier 3 emissions regulations and are compliant with International Maritime Organization Tier II standards for commercial applications. The engines are type approved by the American Bureau of Shipping.


“We’re excited to offer these additional air-cooled ratings, which are designed specifically for the marine gen-set and marine auxiliary engine markets, to the current 9.0L and 13.5L radiator-cooled, dry exhaust manifold engines,” said Heather Balk, marine market planner for John Deere Power Systems. “The range of engine options allow our customers to select the best product for a variety of generator and auxiliary application needs including pumps, winches, cranes and hydraulics.”

Features of both the new 6090HFM85 and the 6135HFM85 engines include:

  • American Bureau of Shipping Type Approval
  • Water-cooled turbo and wet-exhaust manifold
  • Options with and without a marine air cleaner/CCV
  • Isolated ground electronics, including the starter and alternator
  • Available with fan-drive options

“Our complete line-up of marine EPA Tier 3 generator and auxiliary drive engines enable our customers to choose an engine solution that best meets their needs and offers the reliable and cost-effective solutions they’ve come to expect from John Deere. Customers can depend upon new 9.0L and 13.5L engines to keep their operations productive.”
