944K Hybrid Wheel Loader

944K Hybrid Wheel Loader John Deere

  • Net Power: 400 kW (536 hp) @ 1,600 rpm
  • Bucket Capacity: 7.65 m³ (10 cu. yd.)
  • Operating Weight: 53 500 kg (117 947 lb.)

Features

Engine

PowerTech™ EPA Interim Tier 4 (IT4)/EU Stage IIIB engine coupled with a hybrid-electric drive delivers significant fuel savings over 9-yard3 (6.88 m3) loaders with conventional drivetrains.

Hybrid-electric drive system is designed to be more dependable. Brushless A/C generators and motors, water-cooled brake resistors, and solid-state power electronics deliver reliable, long-term performance. Reduced engine-speed range increases wear life over conventional drives.

Productivity

Flow-sharing hydraulic system boasts the fastest cycle times and the quickest boom-raise time in the 944K’s size class, speeding short-pattern truck loading. Each boom and bucket function has its own hydraulic pump for quick, smooth operation, and faster truck loading.

Front fender has been cut back to enable greater visibility to the front tire, so the operator can see when slippage occurs. Fender extensions are available.

Engine runs at a choice of three constant operator-selected rpms, so boom and bucket functions are powerful, responsive, and quick, while optimum fuel efficiency is maintained. Reduces overall machine noise and operator fatigue.

Hybrid-Electric Drive

Hybrid-electric drive smoothly and efficiently recaptures energy to slow the loader when the operator lets off the accelerator. This lessens the load on the engine and reduces fuel consumption.

Nevergrease™ Pin Joints

The NeverGrease option includes a pin-joint system for the linkage and boom joints that eliminates greasing, extends pin-joint life, and provides consistent life across the system.

Quad-Cool™

Quad-Cool design places coolers in a boxed configuration that’s isolated from engine heat, for increased efficiency and durability.

Transmission

Coast-control feature functions like dynamic braking in a hydrostatic transmission, slowing the loader without touching a pedal and helping reduce service-brake component wear.

Controls

Joystick steering adapts to ground speed to deliver smooth, low-effort control for fatigue-beating comfort. F-N-R switch with up- and downshift buttons ensures fast, smooth shifting and directional changes.

Cab Comfort

More spacious cab is 10-in. wider than the 844K-II, making it the largest in its class.

At only 108 dBA, noise is much less noticeable to bystanders than with other loaders, making this loader a good neighbor. For the operator, cab noise is only 72 dBA.

Serviceability & Uptime

All daily service points including fueling are grouped for quick and convenient ground-level access.

The 944K is available with four bucket options, a 6.88-m³ (9.0 cu. yd) spade-nose rock bucket, 6.5-m³ (8.5 cu. yd) heavy-duty granite spade-nose rock bucket, a 7.65-m³ (10 cu. yd.) general-purpose pin-on bucket or a less bucket option.

Four standard tie-off points are located on top of the cab above each ROPS post that meet MSHA and OSHA requirements. The operator or technician can simply remove the bolt and install their safety device while performing service on the 944K.
