Edge protection system of working mechanism

摘要

An implement assembly (10) includes an implement (12) having a forward edge (24) and an edge protection system (20). The edge protection system (20) includes at least one edge shroud (100) having a lower leg (134) that includes a lower end (136) and a lower end inner surface (138), an upper leg ( 110), and a wedge portion (126), the upper leg (110) including an upper end portion (112) and a connecting portion (118). The upper end portion (112) has an upper end inner portion (116) that may be angled to the lower end inner surface (138) and/or a horizontal plane (32) extending between the upper leg (110) and the lower leg (134). The system (20) also includes a boss assembly (34) stmctured to couple the edge shroud (100) to the implement (12), and including a pry boss (36). The angle (152) of the upper end inner surface (116) may be such that a clearance (212) is formed between the upper end inner surface (116) and the pry boss (36) when moving the edge shroud (100) forward in a disengaging direction (202) relative to the implement (12). The clearance (212) reduces factional force (206) opposing movement of the edge shroud (100) in the disengaging direction (202). The pry boss (36) may also include at least one pry notch (58) having a pry surface (60), the pry notch (58) being staictured to receive a free end of a pry tool (308) for prying the pry boss (36) out of the assembly (10) in a pry off direction (304).
