Who It's For

This pulley is ideal for homeowners and professional landscapers who maintain Bad Boy, Ferris, Simplicity or Snapper mowers listed in the fit guide and who need a reliable, OEM-style replacement without modifying the deck. It is particularly useful when a worn or seized idler pulley is causing belt slipping, noise or poor deck engagement.
