This blade set will fit the following models of tractors with 46" decks.
120,140,300,312,314,316,317,318,110,112,170,175,180,185,210,212,214,216,240,245,260,265,285,320,STX46 and early LT166's.
These blades also fit the mowers listed above that are equiped with a model 47 mower deck and model 48 mower deck. Both 47 and model 48 decks actually cut 46 inches. This can be very confusing. They are model 47 and model 48 decks, not 47" decks and 48" decks. If you are unsure about this fitting contact us and we can determine which blade you are needing.
