    The most comfortable seat in the woods.

    This cab is a keeper — so comfortable it will keep you in the woods, working. The 643K's cab is welcoming and spacious, as well as efficiently designed for maximum productivity. You'll appreciate the clear and expansive sight lines, the air-ride suspension seat, and the well-lit Standard Display Monitor (SDM). Instantly check your saw-speed rpm to know when the cutting can begin. The SDM also lets you check your saw speed, fuel levels, and temperature — without bringing work to a standstill.









    When you have a John Deere, you have the John Deere dealer network at your disposal. You'll appreciate the difference you'll see in the knowledgeable sales staff, the certified service technicians, and the well-stocked parts inventory.
