Increase your accumulation capacity
FD22B is compatible with the 643J and 843J Wheeled Feller Bunchers. This head can handle any harvesting operation: from thinning to final cut of up to 559.0 mm (22.00 in.), in softwood or hardwoods.

When you work on sloped ground or with big timber, the increased tilt-back angle of the FD22B saw head will give you better load transfer capabilities and stability. The FD22B also boasts large accumulation capacity, strong clamping force for better tree control, and “workhorse” gathering arms—all of which promise productivity and uptime.
