stevasaurus 22,711 #2 Posted August 18, 2019 Go to the Manuals Section...Implements...mower decks and type in 78345. You will find a ton of stuff to help answer your question. Says it fits 300 and 400 series horses. Share this post Link to post Share on other sites
Lee1977 6,647 #3 Posted August 20, 2019 They made 1973,1974 and 1975 4 speed B-80's short frame might not be enough room for a 42" deck . The 1976 B-80 is a long frame 8 speed it will fit but it will be under powered to handle the 42" deck. Share this post Link to post Share on other sites
