Abstract
A cutter head assembly comprising a first longitudinal member; a second hollow longitudinal member provided with at least one aperture, being coaxial with the first longitudinal member and radially spaced apart therefrom; cup-shaped elements fixedly mounted to a corresponding aperture and to the first longitudinal member; blade holders to removably secure a rotatable blade to the cutter head. These blade holders are designed so as to improve mulching action and resistance to impacts of the cutter head, for use in land clearing and in any operation involving mechanical vegetation cutting.

A cutter head assembly comprising:
- a first longitudinal member;
- a second hollow longitudinal member provided with at least one aperture, said second longitudinal member being coaxial with said first longitudinal member and radially spaced apart therefrom;
- at least one cup-shaped element comprising four side-walls, each said at least one cup-shaped element being fixedly mounted to both a corresponding one of said at least one aperture and said first longitudinal member;
- and
- at least one cutter blade mounted in said at least one cup-shaped element by means of a blade holder having a substantially fin-shaped top surface;
- wherein said blade holder has a longitudinal width that completely fills the interspace between one of said at least one aperture of said second hollow longitudinal member and an adjacent at least one aperture of said second hollow longitudinal tube.
