I'm restoring our John Deere FB-B Grain Drill, which is still in regular use. Several of the cast iron shoes have broken, and I also am in need of the rubber tubes that slide inside the shoes as well as the metal "funnels" that attach to the top of the rubber tubes that the seed and fertilizer falls into from the bins. I have some part numbers from a couple of the existing tubes and funnels (M18748 is the tube and BB3607M is the metal funnel) but John Deere wants $24 for each rubber tube and $61 for each metal funnel which is insane. Moreover, they say they cannot get a drawing in their computers of the parts to even confirm the parts are what I am looking for. I'm hoping that someone on the forum can help me out. I have a parts drawing in my operator's manual, but even that is not apparently available to the guy at the Deere dealership I am talking to. I need a lot of the tubes and funnels and I can't order blindly. What's more, I need a few of the cast shoes. Does anyone know where a person could look for the cast shoes - used or new - and how I can confirm the part numbers are what I need? The metal funnels for example are simple stamped metal pieces that should never approach $61 apiece so I think something is awry at the dealership. Thanks much for any help.
