Short answer
Oregon sells 50TGR1HL3 as a set of three for 50-inch Toro/Exmark zero-turn decks. Toro lists 17.5 in blades for select 34 and 50-inch TimeCutters built 2011 and later, and its 50-inch TimeCutter 77508 has two serial ranges with separate parts records. On Cub Cadet's 50/54-inch double bagger, a 50-inch stamped deck needs a chute adapter first.
