Sorry, I don't have anything that long. I looked at the shaft in parts catalog. I know I am not supposed to rely on graphics in a PC but it appears to be a square bar inside a square tube. Ag department stores sell this type of drive shafts. If shaft is NLA from Deere have you tried piecing one together from another source?
Hopefully this is the same tiller you have. It came on my 332. It does have a square sliding shaft (not rectangular as I thought). Maybe they use different configurations on different speeds as my 400 pto’s are rectangular. The spline is covered with grease for storage but I’m guessing you have the count and dimensions already. My shaft does not slip apart easily, and I’m glad for that, not sure what retains it. If you have any questions I’m happy to go measure or investigate. Hope you can find one, I’m sure you will, plenty of time now till spring.
