摘要： A snow removal system that has a primary cutter assembly and a series of specialized attachments. The cutter assembly is formed from a length of aluminum bent to form a single horizontal cutting bar with two vertical cutting wings. The cutter bar has a tailpiece formed from a length of stiff but flexible plastic attached to the back edge. An elevated center bar serves as the thrust point and fixture for several of the attachments. The attachments to the cutter assembly include: a toggling plate; extensions to the vertical side bars that can be forward, vertical or trailing; a starting aid and depth setter; an edge limiting aid; a broom, set to the proper angle for a given application; an extension to the plastic tailpiece; and a bottom protector plate. Thrust or pull for the cutter assembly is achieved by the use of several special push-pull tubes. A simple elastic cord is used to secure the plastic tailpiece to the cutter assembly for storage.
