Abstract
Abstract THIS CLOSURE DEALS WITH A STATICALLY AND DYNAMICALLY BALANCED CUTTING ASSEMBLY FOR USE IN A MOVER. THE ASSEMBLY INCLUDES A ROTATABLE SHAFT, A PLURALITY OF RADIALLY EXTENDING CUTTING BLADE SUPPORTS SECURED TO SAID SHAFT, AND ONE OR MORE CUTTING BLADES ATTACHED TO EACH OF SAID SUPPORTS. THE SUPPORTS ARE ANGULARLY AND CIRCUMFERENTIALLY SPACED IN A PREDTERMINED PATTERN ALONG A CENTRAL SECTION OF THE SHAFT SO THAT UPON ROTATION OF THE SHAFT, THE BLADES CUT A SWATH WHICH IS SUBSTANTIALLY CONTINOUS OVER THE LENGTH OF THE CENTRAL SECTION. TO BALANCE THE ASSEMBLY, THERE IS SECURED TO EACH END SECTION OF THE SHAFT AT LEAST ONE BALANCE BLADE SUPPORT, AND ONE OR MORE BALANCE BLADES ARE FASTENED TO EACH BALANCE BLADE SUPPORT. THE BALANCE BLADES AND SUPPORTS THEREFOR ARE SUBSTANTIALLY IDENTICAL WITH THE FIRST MENTIONED SUPPORTS AND BLADES, AND THEY ARE AXIALLY AND ANGULARLY LOCATED RELATIVE TO THE PATTERN SUCH THAT THEY STATICALLY AND DYNAMICALLY BALANCE THE ASSEMBLY.
