www.rockproducts.com ROCK products • November 2018 • 51 EQUIPMENT & TECHNOLOGY LOADING & HAULING John Deere added Final Tier 4 engine technology to the 944K hybrid wheel loader, providing customers an increase in fuel economy from the Interim Tier 4 model. Other updates include improving operator comfort and increasing uptime, while lowering daily operating costs. "Customers deserve a dependable wheel loader that actively works to minimize downtime and cut down on fuel consumption," said John Ches- terman, product marketing manager, production class four-wheel drive loaders, John Deere Construction & Forestry. "New and exciting features on the 944K provide operators with a comprehensive loader solution that increases productivity, while efficiently managing costs. But we also main- tained popular features like standard traction control that automatically limits torque to any wheel when slip- page occurs, essentially eliminating runaway tire spin and tire slicing." Equipped with a 536-hp, Final Tier 4 John Deere PSS 13.5-liter engine, the 944K boasts 9 to 14 percent lower fuel consumption compared to its IT4 pre- decessor. The updated engine delivers impressive torque and responsiveness to help maintain good boom and bucket speed in and out of the pile. Along with the engine update, opera- tors will also enjoy an increase in coast control performance. This standard feature gives the operator the capa- bility to adjust the aggressiveness of the machine during deceleration with three different settings. The higher the setting, the more electric braking will occur during application. When all three lights are on, the loader will deliver a 33 percent increase in decel- eration performance and an overall extension of service brake life. Other machine modifications include the addition of a heated and ventilated cab seat to provide maximum comfort. With improved Final Tier 4 technol- ogy, operator and bystander noise levels were also lowered. Outside the cab, remote jump-start terminals were added in a closed and locked engine compartment. These allow for faster and easier jump-starting, can be used with a trickle charger in cold weather and are color-coded/insulated to help prevent improper connections and acci- dental contact with battery terminals. Other updates include a bolted shut engine fan door that reduces the pos- sibility of it accidently opening during operation; the consolidation of the engine stop switch and 24-volt elec- trical disconnect switches on the right side of the machine to provide easier access; and the relocation of the engine block heater plug-in for easier access in colder climates. Warranty coverage on the 944K wheel loader 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. This offer was extended to July 31, 2019, (from Oct. 31, 2018) to existing machines in the field and on new 944K loaders. Fleet managers looking to get the most out of their 944K wheel loader can rely on their John Deere dealers to provide Ultimate Uptime, featuring John Deere WorkSight. With Ultimate Uptime, owners receive predelivery and follow-up inspections that include five years of JDLink telematics, machine health prognostics, remote diagnos- tics, programming capabilities and the ability to add dealer-provided uptime solutions to a customized package.
