ABSTRACT:
A rotary cutting assembly to be attached to a rotary shaft of a weed trimming device for cutting vegetation. The rotary cutting assembly includes a cutting member constructed of a hub and a plurality of cable ties secured to the hub such that a spoke pattern is formed. Due to the cable ties' relatively heavy mass and ability to resist a wide range of dynamic stresses that may be placed thereon during normal operation of the weed trimming device, the cutting member of the present invention can be used to cut through thick and dense vegetation. The cutting member is encased between a top cover and a bottom casing. The bottom casing is defined in part by a semi-dome shaped portion which is sized to engage the outer periphery of the top cover to encapsulate the cutting member to ensure that the hub and the head portion of the cable ties remain protected and insulated from the environmental elements typically encountered by weed trimming device.
