  • Patent number: 5438774
    Abstract: Mechanically attached adapters are beneficial in cutting edge assemblies for the ease of assembly and disassembly. However, they must be easily assembled and disassembled and must be able to withstand harsh operating conditions. In the subject arrangement, a cutting edge assembly is provided including a base edge having a stop member solidly secured thereto spaced from a leading edge thereof and extending upwardly from the base edge. A mechanically attached adapter has a forward working end portion and a rearward end portion for securing the mechanically attached adapter to the base edge. The rearward end portion has an upper strap portion, a lower strap portion spaced from the upper strap portion and interconnected therewith by an intermediate portion to define a cavity. The upper strap portion has an elongate slot which receives the stop member during assembly. A portion of the base edge is received in the cavity and a retainer mechanism is disposed in the elongate slot spaced from the stop member.
