Cully 1 #1 Posted June 29 Need Help Identifying a Mystery 42” Rear-Discharge Deck for a 1989 Wheel Horse 520-H I have a 1989 Wheel Horse 520-H, model 31200E02, and I’m trying to determine if the 42” rear-discharge mower deck that came with it is actually the correct deck for this tractor. This is a barn find. 10.1 hrs on the tractor and attachments in boxes. Mower and single stage blower. The deck has several features that don’t seem to match the manuals or photos I’ve found: ● The PTO/input pulley is at the back left and sits higher than every other 42” rear-discharge deck I’ve seen. ● The deck has a front tongue and cable arrangement that nobody has been able to identify or show where it attaches on a 520-H. ● The pulley arrangement is drastically different from other Wheel Horse 42” rear-discharge decks I’ve found online. ● The deck does have a legend plate, shown in the photo labeled A1 (legend), along with a full deck view in A2 (deck). I have found another 42” rear-discharge deck from a 312-8 that looks completely different, which has me wondering if my deck may belong to another Wheel Horse model or even another tractor altogether. I’m posting pictures of: 1. Entire top of deck 2. Close-up of the tongue and cable 3. Close-up of the pulley arrangement 4. Any castings, stampings, or part numbers I can find 5. Legend plate (A1) and overall deck view (A2) Questions: 1. Can anyone identify this deck? 2. Is it correct for a 1989 Wheel Horse 520-H (31200E02)? 3. If not, what tractor did it originally fit? 4. Would a 42” rear-discharge deck from a 312-8 be compatible with my 520-H or provide usable suspension/attachment parts? Any photos, manuals, measurements, or firsthand experience would be greatly appreciated. I’m trying to determine whether I should restore this deck, modify it, or start with a different donor deck. Thanks in advance for any help. Share this post Link to post Share on other sites

WHX?? 57,628 #4 Posted June 29 1 hour ago, Cully said: restore this deck, Resto heck that deck looks like it's never saw a blade of grass. Never fit a 520. Verticals only and not worth trying to convert. Yah a 10 hour tractor??? NOS fer sure. Share this post Link to post Share on other sites
gwest_ca-(File Mod) 12,416 #5 Posted June 29 This is the same 42" rear discharge but built for the 300, 400 and 500-Series of tractors. The other 36", 42" and 48" width of cut mowers of this type use the same attachment hardware. Click on the fuzzy picture. Share this post Link to post Share on other sites
Lee1977 7,743 #6 Posted June 29 The 3120OE02 Is Correct for a 1989 520-H, I have one. The 1989 models also have the key switch on left side. Share this post Link to post Share on other sites
