ABSTRACT:
An apparatus (22) for delimbing felled trees (12, 14) comprises a rigid frame (28) defining a central aperture (42, 44, 46) which is crossed by a gridwork of resiliently mounted cables (76, 92, 102, 104, 122). Trees are pushed top first through the gridwork, which expands and contracts its apertures to accommodate the changing diameter of the tree, while snapping off its limbs.
