plumb-r 34 #1 Posted May 4, 2020 Could someone give me the blade dimension for the deck blades of a1980 read discharge deck? I've found two different size blades and both say they fit. Share this post Link to post Share on other sites
gwest_ca-(File Mod) 11,033 #2 Posted May 4, 2020 Sorry I don't know the blade lengths. Mower Rotary 1980 42in RD model 05-42MR01 106079 and 106108 blades replaced by 106635 3-blade set (3/4" center hole) Most online parts lists are shared by more than one size or type of deck but fail to identify what fits what. Assuming that is how you are coming up with different blades. Garry Share this post Link to post Share on other sites
