John Deere’s Tier 3 Marine Engine Lineup
John Deere Power Systems (JDPS) has announced that it will meet U.S. Environmental Protection Agency (EPA) Marine Tier 3 emissions regulations with diesel engines from 99 to 750 hp (74 to 559 kW). New PowerTech 9.0L and 13.5L Tier 3 propulsion and generator-drive engines join the previously announced 4.5L and 6.8L Tier 3 models for commercial and recreational applications.
JDPS said its Tier 3 marine engines also meet current European Union emissions requirements for propulsion engines used on recreational crafts and inland waterway vessels. The engines also meet current limits established by International Maritime Organization (IMO) MARPOL Annex VI.
The PowerTech 6090AFM85, PowerTech 6090SFM85, PowerTech 6135AFM85 and PowerTech 6135SFM85 propulsion and generator-drive engines are the latest additions to the John Deere Tier 3 lineup. Tier 3 regulations impacting these 9.0L and 13.5L engines take effect in 2014.
John Deere has added two new 9.0L models to its lineup of Tier 3 marine engines: the PowerTech 6090AFM85 and PowerTech 6090SFM85 propulsion and generator-drive engines.
The PowerTech 6090AFM85 is an air-to-coolant aftercooled version of the John Deere 9.0L engine and is available in four different propulsion ratings from 285 to 425 hp (213 to 317 kW); gen-set ratings include 297 hp (222 kW) at 1800 rpm for 60 Hz and 261 hp (195 kW) at 1500 rpm for 50 Hz.
The PowerTech 6090SFM85 is a turbocharged and air-to-seawater aftercooled engine. The model is available in five different propulsion ratings from 325 to 550 hp (242 to 410 kW); gen-drive ratings include 298 hp (222 kW) at 1500 rpm for 50 Hz and 373 hp (278 kW) at 1800 rpm for 60 Hz.
John Deere 13.5L Tier 3 propulsion and generator-drive engines include the PowerTech 6135AFM85 and PowerTech 6135SFM85.
The PowerTech 6135AFM85 is the largest John Deere air-to-coolant aftercooled engine. The engine is available in four different propulsion ratings from 365 to 575 hp (272 to 429 kW); gen-set ratings include 448 hp (334 kW) at 1800 rpm for 60 Hz and 373 hp (278 kW) at 1500 rpm for 50 Hz.
The PowerTech 6135SFM85 is the most powerful engine produced by John Deere. The turbocharged and air-to-seawater aftercooled engine features six cylinders and electronic controls, designed to provide high torque at low speeds. The 6135SFM85 model is available in five different propulsion ratings from 425 to 750 hp (317 to 559 kW); gen-drive ratings include 558 hp (416 kW) at 1800 rpm for 60 Hz and 448 hp (334 kW) at 1500 rpm for 50 Hz.
