JOHN DEERE 944K HYBRID WHEEL LOADER

Technical Description

The John Deere 944K Hybrid is a large-capacity wheel loader featuring a revolutionary hybrid-electric drivetrain system engineered to maximize productivity while minimizing fuel consumption and operating costs. Powered by a John Deere 13.5L engine delivering 536 horsepower and 1,866 lb-ft of torque at 1,600 rpm, the machine employs an AC electric transmission with four three-phase switched reluctance motors and dual AC permanent magnet generators to recapture energy during deceleration. The loader accommodates bucket capacities ranging from 8.5 to 10.0 cubic yards, supported by an operating weight between 119,607 and 124,614 pounds. Standard features include exclusive traction control that automatically limits torque to prevent wheel slippage and extends tire life, plus coast control for dynamic braking adjustment during deceleration. The machine utilizes 35/65 R33 tires with wet multi-disc braking on all wheels and incorporates a Z-bar linkage with dual-slab boom cylinders for exceptional visibility. With a maximum travel speed of 24.2 mph in fourth range, the 944K Hybrid delivers quick boom-raise times and rapid cycle times, making it ideal for quarrying and aggregate operations. The hybrid-electric drivetrain components are backed by an 8-year, 20,000-hour warranty, while the Interim Tier 4 compliant engine ensures environmental efficiency alongside reduced fuel consumption compared to conventional loaders of similar capacity.
