David414 289 #1 Posted June 8, 2020 Brought a used 48" SD deck and the model number sticker only has 783 or could be 782. I can't read the rest of the model number. Seller claims it came off a 520 WH. I need help in identifying the model number and year. All pulleys came off without using a puller, and pulleys are not keyed. Just removed the spindle nuts, and pulleys slid off. It has a two piece deck, the main shell and a second elongated metal deck that sits on top of the main shell. Thanks!

gwest_ca-(File Mod) 11,033 #3 Posted June 8, 2020 I don't know if this will work or not Go to this page which is 19 of 26 pages. The decks are in older to newer order. https://www.wheelhorseforum.com/files/category/18-mower-decks-reel/?sortby=file_name&sortdirection=asc&page=19 Start at Mower Rotary 48in SD 1993 78360 3-4-500 OM IPL SN.pdf which is when they started with that type of model number. Look for the 3-4-500 which is a deck for your size/style of tractor. All 48" decks have the top reinforcement plate. A very strong deck. Garry Share this post Link to post Share on other sites
daveoman1966 3,745 #4 Posted June 8, 2020 111726 or 110172 is the correct spindle for 42 or 48 decks that DO NOT use the Woodruff key in the top pulley. Share this post Link to post Share on other sites
