PURPOSE: A cutting unit for a glass eliminator is provided to selectively use a string type cuter, a linear cutter, or a circular cutter according to the need of a user, and to prevent entanglement of cut grass. CONSTITUTION: A cutting unit for a glass eliminator comprises a base plate(110), an impeller(120), a circular blade, a linear blade(160), an automatic string-unloosing unit. The base plate can hit and clear cut grass, and replace various cutters. The impeller is combined with a rotary shaft of the grass eliminator. The impeller is hinge-combined to be spread by a centrifugal force due to rotary force of the base plate. The impeller is coupled from a lower part of the base plate to the rotary shaft to rotate together with the base plate so that cutting work can be conducted by the centrifugal force. |
