John Deere 644k Features


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