John Deere introduces marine Tier 3 auxiliary engines

PowerTech 6.8L auxiliary engine

MAY 5, 2014 — John Deere Power Systems has introduced a full line of radiator-cooled, dry-exhaust-manifold PowerTech auxiliary engines suitable for powering a variety of deck auxiliaries including pumps, winches, cranes, hydraulics and generators.

The line-up meets U.S. Environmental Protection Agency Marine Tier 3 emissions regulations for U.S. waterways, and offers reliable, cost-effective power to customers for their auxiliary applications.

“We’re pleased to expand our product line with Marine Tier 3-certified auxiliary power solutions for customers working the U.S. waterways,” said Heather Balk, marine market planner at JDPS. “Our customers can depend on the performance of these engines to keep their operations productive.”

Marine Tier 3 PowerTech auxiliary drive engines were developed based on the proven hardware of the John Deere PowerTech non-road Tier 3/Stage III A in-line, 4- and 6- cylinder engine platform.

With displacements from 4.5 to 13.5L and power ratings from 74 to 448 kW (99 to 600 hp), these engines offer constant- and variable-speed ratings to meet a wide variety of application needs.

The PowerTech 4.5L engine is available with constant-speed ratings of 78 and 129 kW (105 and 173 hp) at 1800 rpm.

Variable-speed ratings for the lineup include:
PowerTech 4.5L: 74 kW (99 hp) at 2200 rpm
PowerTech 6.8L: 187 kW (250 hp) at 2200 rpm
PowerTech 9.0L: 280 kW (375 hp) at 2200 rpm
PowerTech 13.5L: 448 kW (600 hp) at 2100 rpm

“Our Marine Tier 3 auxiliary drive engines offer more of the reliable and cost-effective solutions that customers expect from John Deere,” Balk said.

John Deere Power Systems is debuting a radiator-cooled, dry-exhaust-manifold auxiliary Marine Tier 3 engine at the 2014 Offshore Technology Conference (OTC), May 5 – 8 in Houston. The PowerTech 6.8L auxiliary engine will be on display in booth 5765.

All John Deere marine power solutions are available through John Deere marine engine distributors and marine dealers.

Marine Tier 3 auxiliary drive engines will be available for order in summer 2014, with expected delivery in fall 2014.
