mikemc53 10 #1 Posted August 16, 2020 I have been trying to find replacement blades for either or both of my tractors. I have a 1974 B-100 with 36" side discharge deck and a 1978 C-81 with a 36" rear discharge deck. I really only use the C-81 because the deck for the B-100 has been cannibalized and doesn't have much left. I did notice the blades are the same size but the B-100 has what appears to be high lift blades and the other does not. First, are they interchangeable? They sure seem to fit but not sure if there is a problem putting one in the other deck. Secondly, and most important, where can I get replacements? Nobody seems to have part numbers that cross reference these and both pairs of these are pretty beat and I could really use a new set or two. Thoughts?
