John Deere Forestry and Construction unveiled its new 644K hybrid wheel loader at World of Concrete this week. It was developed using a culmination of show floor input from Deere’s “Chatterbox” customer feedback program and in-the-field comments. The loader will be on display at the AGG1 Aggregates Academy & Expo in March. Look for more detailed information about the machine in the RollOuts section of our upcoming March issue.
