635H Swing Boom Skidder

Overview

�ǿմ�ý's highest capacity skidder equipped with a versatile swing boom improves productivity in the most challenging terrain. The additional working envelope and ability to position the grapple well outside of the working track of the machine is an asset in applications where skidder travel is restricted or limited by terrain characteristics.
