Important Fitment Note
MTD-built tractors were sold under many different brand names and may share individual blades or spindle assemblies. However, that does not automatically mean this complete 6-piece kit fits every mower using one of these components.
This kit should only be used when your deck requires the complete combination of 3 compatible 618/918-0660-family spindles + 2 long 742/942-04125-family blades + 1 short 742/942-04124-family blade.
