    FR27 felling head FR27 felling head

    From small stems to big timber, softwood to hardwood, level or sloped ground, John Deere has a disk saw felling head that’s designed for your job. The new FR27 boasts our highest single-cut-capacity, with over 16 percent more accumulation area than the FR24B, making it an excellent choice for large timber. Delivering efficient, multi-stem high-accumulation performance with huge pocket and tall horns, the FS50 and FR50 felling heads are best suited for thinning and high-production plantation harvests. For more versatile applications, the FS22B and FR22B heads are robust enough to handle large trees, with the tree-handling performance to also efficiently accumulate mid-sized timber. If lightweight is a must, the FR21B is our lightest, high-rotation head that is optimized for small to mid-sized timber. 

    • Wide range of in-house felling head attachments 
    • Optimized for John Deere carriers 
    • Heads are factory-installed 
    • High-rotation heads provide easier placement of bunches

    Operating for long hours is common. As the day goes on, maintaining consistent productivity is important. One factor in keeping high, consistent productivity is a comfortable operating environment. The M-series boasts greatly increased window area for better visibility and more cab space over prior models. Low-effort electrohydraulic (EH) controls allow you to customize the button and lever layout to your preference and save your settings when switching between operators. 

     

    • Large and spacious operator station designed with operator input 
    • Ergonomic controls and increased cab volume over prior models  
    • Floor-to-ceiling front window, large side windows, skylight, and optional floor window (standard on leveling machines) significantly expands operator visibility
