The revolutionary hybrid-electric drivetrain consists of the John Deere 13.5L engine, gearbox, two 3 phase Alternating Current (AC) permanent magnet generators, power electronics or inverters, four 3 phase Alternating Current (AC) Switched Reluctance (SR) motors, four 2 stage reduction final drives, and two brake resistors. The electric drive components are backed by an 8-year, 20,000 hour warranty providing peace of mind when investing in this machine.
Enjoy peace of mind with a standard, limited, or basic warranty on specific 944K electric drive generators, brake resistors, wheel motors, and inverters for 8 years or 20,000 hours, whichever comes first.*
*Through July 31, 2022. Components must be rotated between 15,000 and 18,000 hours. Drive voltage cables are not covered and must be replaced between 15,000 and 18,000 hours. Annual machine inspection must be performed by an authorized John Deere Construction and Forestry dealer.
The 944K is the most fuel-efficient machine in its size class meaning that it can move more material while burning less fuel. This allows operations to put more material through the crusher while burning less fuel. In addition, it’s design efficiencies help realize additional environmental impact reductions through common tasks on aggregates jobsites helping to lower carbon emissions and reducing the 944K’s overall environmental impact.

The 944K comes with exclusive and customizable features that ensure maximum productivity occurs while also reducing fuel consumption and tire slippage, which are major drivers in a machine's operating costs.
Loaders in this size class are expected to last multiple lives and total cost of ownership is a key factor in upfront purchasing decisions. Since the 944K does not contain major components like axles and a transmission, those components will not need to be rebuilt or replaced like a conventional drive loader. Because of this, a MidLife event between the 15-18k hour range costs approximately 50-60 percent of the cost of rebuilding a traditional drive machine.
Maintaining visibility to your surroundings is crucial in applications that the 944K is utilized in. With that in mind, John Deere has designed the machine to allow optimum operator line of sight to key components like the bucket and tires while also offering additional features that enhance visibility around the entire machine. The 944K cab is the largest in the Deere loader lineup and provides functions that enable overall ease of operation.
The 944K offers the lowest preventative maintenance cost per hour in it’s size class over traditional drive loaders and is designed with ease of serviceability in mind through both ground level and left and right side lighted platform access. It also comes with the Quad-Cool™ Cooling System, a John Deere exclusive, that places the radiator, air-conditioner condenser, intercooler, and charge air, hydraulic, fuel, gearbox, power electronics and axle coolers in a unique boxed configuration that is isolated from engine heat to more efficiently cool these components throughout the day.
