    Choose from three different felling heads to match your application, tree size, and conditions, so you can maximize productivity. The twin-post FD45 and FD55 heads provide deep pockets for high-accumulation performance and are best suited for thinnings and high-production plantation harvests. The single-post FD22B head is best suited for large timber in clear-cutting applications.

    • Multiple head options to fit the machine to its intended application
    • Factory installed felling heads
    • Optimized for John Deere carriers
