John Deere has added Tier 4-F engine technology to the 944K hybrid wheel loader, leading to an increase in fuel economy over the company’s Tier 4-I model.
Other machine updates include improved coast control performance, a heated and ventilated seat, and remote jump-start terminals.
Equipped with a 536-horsepower, Tier 4-F John Deere PSS 13.5-liter engine, the 944K front end loader manages 9 to 14 percent lower fuel consumption compared to its Tier 4-I predecessor.
Along with the engine update, Deere points to an increase in coast control performance. The standard coast control feature gives the operator the capability 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 coast control-setting lights are on, the loader will deliver a 33 percent increase in deceleration performance, and an overall extension of service brake life, according to the company.
Other machine modifications include the addition of a heated and ventilated cab seat, and lower operator and bystander noise levels thanks to Tier 4 technology aftertreatment devices for the SCR system that help make the exhaust quieter, Deere says.
Outside the cab, remote jump-start terminals were added to all 944K Tier 4-F machines 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 accidental contact with battery terminals.
Additional updates include a bolted-shut engine fan door that reduces the possibility of accidently opening during operation; the consolidation of the engine stop switch and 24-volt electrical 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.
The hybrid loader retains standard traction control that automatically limits torque to any wheel when slippage occurs, designed to eliminate runaway tire spin and tire slicing.
Warranty coverage on the wheel loader includes an eight-year or 20,000-hour (whichever comes first) nonprorated assurance on wheel motors, generators, power inverters, and brake retarders. This offer was extended to July 31, 2019 (from October 31, 2018) to existing machines in the field and on new 944K loaders.
With the loader, John Deere dealers can provide Ultimate Uptime, featuring the WorkSight suite of telematics solutions.
As part of Ultimate Uptime, owners receive predelivery and follow-up inspections that include five years of JDLink telematics, machine-health prognostics, remote diagnostics, programming capabilities, and the ability to add dealer-provided uptime solutions to a customized package.
