the arrangement in fig4 improves mulching action since the elevated leading edge of aerodynamic member 11 cuts vegetation at an elevated level while the vegetation is still attached to the vegetation roots primary cutting member 15 then cuts the vegetation to the final cutting height another variation of the embodiment fig5 shows a longitudinal edge view of blade 10 of fig2 along line 31 which employs multiple vegetation shredding and aerodynamic vegetation directing members detail 11 and 12 ahead of the primary cutting member 15 this arrangement where all cutting edges are configured to the same approximate cutting height is useful for mowing vegetation that would be trimmed many times per week such as golf course grasses another variation of the embodiment fig6 shows the longitudinal edge view of blade 10 of fig2 along line 31 with the inclusion of multiple vegetation shredding and aerodynamic vegetation directing members in various orientations and elevations detail 11 and 12 in relation to the cutting plane 21 the vegetation shredding and aerodynamic vegetation directing member arrangement in fig6 detail 11 and 12 further improves mulching action since members 11 and 12 will cut vegetation at multiple levels while the vegetation is still attached to the vegetation 39 s roots the leading edge of the primary cutting member 15.
