John Deere 644k Wheel Loader Features


The EPA Tier 3/EU Stage IIIA PowerTech engine has a lot of torque, which helps keep the boom and bucket moving quickly in and out of the pile, even when the material is wet or hard.


  • Powertrain and hydraulic performance that can’t be beaten help keep the ground speed and lift boom quick for faster cycles.
  • K-Series Loaders have a wide stance that gives them more stability on the sides so they can carry heavy loads and work on rough terrain.
  • With a low center of gravity and a well-balanced front-to-back design, the full-turn tipping load capacities and stability are very good.

Hybrid-Electric Drive
