John Deere expanded its E-Series articulated dump truck (ADT) lineup with the addition of the 260E and 310E, an announcement the company made at ConExpo-Con/Agg 2017.

According to John Deere, the 260E and 310E boast updated styling and new cabs, frames and axles compared to their D-Series predecessors.

“Our customers in the field expressed interest in the features that launched with the larger E-Series models, including increased hauling capacity; a larger, quieter cab; convenient ground-level daily service and increased travel speeds,” says Maryanne Graves, ADT product marketing manager at John Deere Construction & Forestry. “We worked closely with road builders, site developers and the mining, quarry and aggregate segments to develop trucks that are purpose-built and feature the performance, productivity and durability they expect from a John Deere machine.”

The 26-ton, 321-hp 260E and the 31-ton, 354-hp 310E feature a John Deere PowerTech 9.0-liter Tier 4 Final engine. A purpose-built ZF transmission includes a high-capacity retarder, eight forward gears and four reverse gears. Compared to previous models, these trucks have a 125 percent increase in retardation capacity, the company says.

In addition, John Deere added the 844K Series-III and 844K Series-III Aggregate Handler to its wheel loader lineup. The machines offer customers increased uptime and the ability to sell more material more efficiently to improve their bottom lines, the company says.

“The 844K-III is designed to take on the toughest aggregate and material-moving applications in the world,” says John Chesterman, product marketing manager of production class four-wheel drive loaders at John Deere Construction & Forestry. “We worked closely with our customers to design these productive machines to be even more rugged and reliable. The Aggregate Handler configuration of the 844K-III can load out 24 short tons of non-heaping, lower-density processed matter in just two passes into on-road dump trucks. Heavier heaping materials achieving 12-plus tons is not a problem.”

The new wheel loaders offer a 13.5-liter John Deere PowerTech Tier 4 Final diesel engine that delivers 380 hp for the 844K-III and 401 hp for the Aggregate Handler configuration, John Deere adds. The models are equipped with a standard five-speed transmission with torque-converter lockup in gears two through five. This feature increases acceleration, speeds and cycles, and optimizes power and fuel efficiency during transport, roading, and ramp climbing.

John Deere also introduced the 950K crawler dozer at ConExpo-Con/Agg.

“The 950K crawler dozer is one example of how John Deere is listening and responding to our customers, and investing in the production-class dozer market,” says Nathan Horstman, crawler dozers product marketing manager at John Deere Construction & Forestry. “Contractors are demanding more precise grading on large projects, and the 950K is giving customers the power and control to be more successful than ever. The 950K is a Deere-designed machine that is fully supported by John Deere dealers and is a strong contender in its size class.”
