From small stems to big timber, softwood to hardwood, level or sloped ground, John Deere has a disk saw felling head thatu2019s 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.
